Very slow Wifi 5GHz, Intel 8260 (2x2), bad wifi performance in general !!! #307

Open Kherby opened 6 years ago

Kherby commented 6 years ago

Today i've noticed that websites were loading very slow when i was connected with my WRT3200acm. Iperf test shows again that something is wrong with the throughput.... This happens every day and i have to reconnect Wifi or restart the Interface to fix it. Also the general 5GHz Wifi performance is bad most of the time, same with 2.4GHz. The throughput is not stable for some reason, even when i'm very close to the Router...

Why is the speed dropping to ~30-40Mbps when i'm only 1m away from the AP ?? Why is this only happening with the WRT3200acm and not with my other Hardware ?? Is the wifi unit defective ?! Do i need to contact Linksys for a replacement ?? Or is it just the marvel driver causing this issues ? What can i do to fix the sloppy wifi performance ? Btw, im even using Linksys High Gain Antennas (WRT004ANT)... I'm using the latest Intel Wifi drivers and 5Ghz works just fine with my other Hardware... For example here is a test with my DIR-860L @ 5GHz:

How about the test result with stock firmware?

Kherby commented 6 years ago

I'm going to post a stock firmware test result later, but i'm pretty sure it will be the same... :/ Do these iperf tests look normal for you ? Especially the test 1 meter away from the router ? Also the Wi-Fi signal strength does change alot and i haven't encounter that with any of my other Wifi Routers before. My warranty will be over soon and before i blame the marvel driver i really want to make sure that my hardware is not damaged.

Other people with OpenWRT doesn't seem to complain about fluctuating throughput, so i kinda think that my hardware isn't allright... ? Do you have any idea how i can make sure that the Wifi chip is alright ?

ghost commented 6 years ago

I just want to chime in here due to I also have the WRT3200ACM with the four high gain antennas from Linksys (aka Belkin).

Might I add @yuhhaurlin is not a developer for OpenWrt but for Marvell itself (some folks get that mixed up) as this github repo is by the maintainer (kaloz) for the Marvel mvebu target at OpenWrt.

I have had similar issues however you have left out lots of crucial information.

Contrary to some information online the Linksys high gain antennas are not intended for multi level dwellings (though it does work just fine installed in the basement mounted on wall with antennas pointed upwards).

One major drawback for the WRT3200ACM series for 5ghz DFS channels is lots of RF interference and actual radar signals.

Exactly what WiFi channels are you testing on, is there lots of interference on current or nearby channels plus are all your tests on the same channel?

yuhhaurlin commented 6 years ago

If you have the same issue with stock firmware, you can check with Belkin. How about other clients?

Kherby commented 6 years ago

I've tested a Dell Notebook with Qualcomm QCA61x4A 802.11ac (2x2) Adapter and the throughput seems to be better and way more stable than with my Intel 8260 (2x2) Adapter....

The Intel 8260 doesn't seem to be a bad adapter but for some reason it doesn't work well with the Marvel Wifi chip or the used driver... With the Qualcomm Adapter it seems to be fine and there are no evil speed drops to 30-40mbps like with my Intel 8260 adapter... I'm using driver version: 20.60.07 (09.05.2018) at the moment. Should i test an older Intel driver ?

@ryan-dev: All test done via channel 100(DFS-Auto) @27dBm and at the same place... I bought the high gain antennas and i only use them on a horizontal plane and installed them poitining updwards... There are some other 5GHz AP's in my area but not that much and none of them are near Channel 100 and as i said i dont have any problem with my DIR-860L using OpenWRT and the Intel 8260 Adapter. I've also tested channel 36 and 52 @20dBm and it doesn't make any difference, same drops, ~same throughput.

Marvel and Intel 8260 doesn't seem to go well together and I don't think my Intel adapter is faulty as i only have these problems with the WRT3200acm. As requested im going to test my Intel Adapter with the stock firmware but im pretty sure that it won't change the problem at all...

Is there anything else i can do ? I really want to fix the problem and it maybe could help others as well !

No more speed drops to 40Mbps and stable performance :/

So imho the bad performance with my Intel 8260 Adapter has to be something with the Marvel Wifi driver within OpenWRT. The good thing is that i now know the hardware of my WRT3200acm isn't damaged. I bought the device only for OpenWRT and the stock firmware doesn't even give me 10% of the functions i need for my network and internet setup.

@yuhhaurlin, can you please fix this problem ? I beg you...

Kherby commented 6 years ago

So as i really need OpenWRT for my setup i did a clean flash of the latest Davidc502 build r7360 and the problem with the speed drops and bad performance does reappear... :(

@yuhhaurlin , there has to be something wrong with this driver. With my Intel AC8260 adapter it seems to be completely out of line...

yuhhaurlin commented 6 years ago

Thanks for your information. I will check it later.

Kherby commented 6 years ago

@yuhhaurlin , i have an additional information that might help you... I had some setup problems with the lastest build of davidc502 so i reverted back to the latest build before r7360...

Right now i'm using build r7210 and my initial testings @5GHz with iperf reverse mode (-R) are looking quite good... But without -R the Speed is still dropping down to 40Mbps. So when my Intel adapter is receiving the data instead of sending it everything seems to be alright...

It's so confusing !!!

yuhhaurlin commented 6 years ago

Yes. Look like Tx has problem with intel 8260.

PalebloodSky commented 6 years ago

It's absurd there are totally separate developers and projects for the closed source and open source Wi-Fi drivers for these WRT routers. The reputation is already poor for Belkin/Linksys' lack of support and this kind of stuff keeps happening. It should be one source code for all and things would get much better.

yuhhaurlin commented 6 years ago

How? Open source is not the same as proprietary driver.

jukkapirinen commented 6 years ago

I think @palebloosky means the firmware blob what is not opensource? But similar it is for atheros as well?

Edit: or he means the Linksys OEM is using own proprietary driver?

Kherby commented 6 years ago

@yuhhaurlin Any news ? Can we expect a fix for the Intel AC8260 adapters ? :)

@b-h-l-c It was driving me crazy as well... At the beginning i thought that my adapter is faulty or the antennas of my Notebook are damaged in some way, but I quickly realized that the poor performance only occurs with my WRT3200ACM@OpenWRT. With my other AP's the Intel 8260 card is working just fine. I realy hope that yuhhaurlin will be able to fix this problem as the Intel 8260 is a pretty common adapter used in many notebooks...

PalebloodSky commented 6 years ago

The last Linksys firmware update changelog says this: "A-MSDU max frame size capped at 7.9K to improve interoperability with Intel 9260-based clients", I wonder if something related could fix the 8260s too.

yuhhaurlin commented 6 years ago

Thanks for your information.

BrainSlayer commented 5 years ago

okay i put some informations here about iperf. running iperf on the WRT itself is a bad idea. iperf will decrease the network performance by its own cpu load and the timer accuracy in these devices is not as good as in a standard pc. so it will fuck up every measurement. run iperf on a second pc connected to the router and then do your measurements. everything else will just give you bogus results

BrainSlayer commented 5 years ago

next hint. use always multiple tcp streams. single tcp streams are meaningless and will never show the full performance. and best for measuring the real throughput is using udp for sure. all these tests here are tcp based which isnt really the best way to get the maximum throughput

yuhhaurlin commented 5 years ago
  1. Test from router is simply to check if throughput has problem.
  2. For our QA, the throughput is measured with multiple streams in shielding room for UDP and TCP between LAN and client.
  3. In open air, it is better to have a reference AP to compare throughput.
  4. Different clients with difference version of drivers sometimes will get different test results.
  5. You need to know capability of your client to know the throughput it can reach.
Kherby commented 5 years ago

@BrainSlayer I've always tested the Wifi throughput with a decent PC (i7, 16GB RAM, SSD) as server, which is connected via Gigabit LAN. Could you please tell me the iperf commands (server+client) for proper testing with UDP?

Same issue here with an Intel 6300agn as client (and WRT3200ACM as router). When transmitting in laptop->router direction using the stock image, the bitrate stays at about 200 MBit/s, using OpenWrt it periodically fluctuates between ~200 MBit/s and ~40 MBit/s, resulting in an effective rate of ~120 MBit/s. In both cases Windows reports a constant nominal bitrate of 450 MBit/s. I would really be interested in a fix. Let me know if you need some information from me.

Kherby commented 5 years ago

I'm going to test Intel 8265 in a few days (HP Probook) with the WRT3200 @OpenWRT and let you know if the same problem occurs.

And i would appreciate if someone could tell me the right iperf commands for multiple TCP streams and UDP testings...

makedir commented 5 years ago

Was hinted by someone else to this thread.

I have the following issue on my WRT1200 with the latest firmware by David502. I got a new laptop which is my first unit, which is able to do at least 866mbit over 5Ghz, my older laptops just all could do 300mbit. It has an Intel 9260 card. The issue now is, that the moment I send files from it to the network, the file copy process breaks down after 1-2 seconds and goes to 0 kb/s and idle out after a long time and give a network error. Doing a ping while this happens, the ping to the router suddenly all goes up to about 133ms. Downspeed from the LAN to the laptops works normally of about 33MB/s (which is also though not close to half of 866mbit, it should be in theory for half duplex be around at least 420mbit). Windows show 866mbit and 4 green bars to the WRT1200. Config for the 5Ghz is option htmode 'VHT80'. Setting it to HT40, and the upload works stable for the 300mbit. Anyone else have similar issues or know what could cause it?

I tested a second router (non Openwrt, factory firmware) I had to hand which also can do 866mbit on 5Ghz, and the upload works stable from the laptop to the LAN, though a bit slow, about 27mb/s.

Kherby commented 5 years ago

@yuhhaurlin Any news ?

alexhartl commented 5 years ago

@Kherby , could you test your performance when running Linux on your notebook? On my machine (Intel 6300agn) wifi performance is quite bad running Linux with 2%-10% packet loss for both the stock image and OpenWRT. I wonder if this is a problem for all Intel cards or just for my card specifically. Not sure if this is related to this bug, though.

makedir commented 5 years ago

I actually noticed, that I also have bad performance with an Intel 6235 card with my old laptop. That was actually the reason why I bought a new laptop... which now has a 9260 card. The 6235 has random high ping jumps (60-100ms) and also it seems to have a bit of packet loss too, because I always have random lags when I use InputDirector to remote control over to a PC, and the connection uses UDP.

These problems, also with bad performance for the 9260, also happen with another router I have which doesnt use OpenWRT. I can also make the router crash and reboot by a certain way of sending large amount of files. The bitrate also fluctuates a LOT, between 20-65MB/s, also goes to 0KB/s for some time.

Kherby commented 5 years ago

@alexhartl, i will test the performance under linux but i can only speak for the Intel 8260 chipset... In the meanwhile i've also updated to the lastest Intel driver (20.70.0.5) and the lastest mwlwifi driver version but the bad performance (Tx) haven't changed. I'm still hoping that @yuhhaurlin will sort out these issues...

Don't you have another router to test, if the Intel cards behave that bad on them too? Because I tested it, and they do, at least, someway. Maybe the better place to post the problems is on the Intel forums, or next to this.

alexhartl commented 5 years ago

I tried with a TP-Link router and a Ubee router and didn't have any packet loss and good rates with both of them. However, they don't have the same capabilities as the WRT3200 (only 2x2 mimo), so yes, this could also be an issue on the Intel side. Yet I think if Intel cards still weren't able to handle 11n properly on Linux there would be tons of discussions about this around the Internet... I'm not sure if we're talking about the same issue here, because my packet loss problem only occurs with Linux and concluding from your use of InputDirector, you were running Windows on your old laptop, right?

makedir commented 5 years ago

Laptop Wifi cards just can do 2x2. My 6235 card was never stable for years and had always problems on the 5Ghz, it was a bit better on 2.4Ghz. The moment you used n mode it became unstable. But the 9260 is terribly worth, it seems to get even worse the more channels it uses simultaneously. 1 channel (50mbit) ok, 2 not so ok, 3-4 bad bad bad. Yes Windows, and when I use InputDirecotr and go with the mouse over to other PCs, I have random lags with it. Because it uses UDP, it is really "picky" for tiny little packet losses. I always thought it was because of bad OpenWRT wifi drivers, but I have the same issue on another router with the Intel card.

My Intel 8260 card does work completly fine with my DIR-860L B1@OpenWRT (MediaTek MT7612E, MT7602E) and as i said it's also working fine with the lastest stock firmware of the WRT3200ACM. Only mwlwifi@OpenWRT seems to have problems with this card...

still no word from the devs...

chris-dk commented 5 years ago

Unfortunately I am facing the exactly the same problem ("speed drops reducing the average speed") with my setup: WRT1200AC v2 running OpenWrt 18.06.1 and Lenovo T480s (Intel 8265) running Fedora. It is a pitty to not have the full speed available.

Are there any news for future development or any plans to fix this problem?

OpenWrt SNAPSHOT, r8119-87d7a596ec wifi drivers from Fixed hidden SSID problem of 88W8997.

diizzyy commented 5 years ago

Have in mind that there are a multitude of environmental factors that can and will affect your wireless performance which makes debugging hard apart from obtaining the exact same hardware if it's even possible.

For what it's worth, I'm having zero issues with various phones, laptops and consoles and they're getting at least ~200mbit depending whether they're 11n or 11ac (5Ghz) if there's good signal strength.

A few devices that works fine (I don't know specs of all devices used) - WRT3200ACMs running OpenWrt master miniPCIe AR9382 (Windows 7+Linux, 11n), Intel 9260 (Windows 10, 11ac) Qualcomm Snapdragon 615/617/625/810 (11n and 11ac) Playstation 4 (low signal strength, doesn't seem to perform any slower than with my old TL-WDR3600)

In my personal experience older Intel cards (6xxx) and (8xxx) have poor reception and can be quite unstable irregardless of radio used in AP (both on Windows and Linux) while they may occasionally work fine but it's rare. In general I'd say that older hardware irregardless of brand works quite poor compared to current gen or previous.

In general I'd say that older hardware irregardless of brand works quite poor compared to current gen or previous.

That might be true but in my case (Intel 8265 2x2) the stock wifi driver of the Linksys Firmware works absolutly fine (no speed drops and good perfomance), DIR 860-L B1 (MT7612E) works fine and my Asus RT-N66U (BCM4331) also works fine with this Intel card! So this tells me that there is no general issue with the Intel card or the Intel driver and problem is only caused by the mwlwifi driver...

Well, maybe the last commit has fixed the speed drops/bad performance with the Intel cards. I haven't had the chance to try the latest driver yet, so feedback is welcome. https://github.com/kaloz/mwlwifi/commit/ccdb4faec454519adf171595ffb94679dc5b1469

All I can say for now is that i'm kinda dissapointed that there is no real feedback from the dev regarding to this problem after such a long time and many reports! :/

ghost commented 5 years ago

I am using @davidc502 OpenWrt builds on my WRT32X and a Dell Precision 5510 with Intel 8260 WiFi card and get an average of 300+Mbps download and upload speed over 5GHz connection and I did not experience connection drops except there was 1 build (I can't remember which build) which my laptop kept dropping the connection, but it's stable with this current build. I am still using the old davidc502 LEDE r8082 (Which is the September 20 2018 build).

What's your settings like? Can I see? and what's your router SKU?

Alternatively, you could try updating your Intel WiFi driver firmware to see if it still drops. or try MTU size of 1400 and see if it helps

makedir commented 5 years ago

Blah blah blah. I also am using Davids build on a WRT1200 and have bad bandwidth with both older Intel cards and also an 9260. It is the only 5Ghz device in range, no radar, no walls, 2m air to air connection. ~300Mbps is terrible where it should be 866.

yuhhaurlin commented 5 years ago

Air to air the throughput should be divided by 2.

makedir commented 5 years ago

... I get about 12-22MB/s with an Intel 9260 on 5Ghz, no other routers, no walls, real throughout, it just randomly drops by 50%, even goes to zero sometimes. And 22MB/s isnt (866/2=433mbit), it is something like 180mbps.

diizzyy commented 5 years ago

@makedir Snarky comments doesn't help at all, in fact it will make people care even less about your issues.

makedir commented 5 years ago

What issue? It is not my issue anymore. I bought a proper AP months ago and disabled the wifi of the WRT. I guess they develop this wifi driver in their free time it seems so it is not really a complaint. Wifi never worked on these routers, and if they changed the driver, they brought in 10 new bugs. It also seems they have stopped working on the firmware for the WRT1200 long time ago, it was last updated 2 years ago or something.

s-pimenta commented 5 years ago

As I said before, they are not taking the issues seriously, even seen people offering MONEY to get this DONE quickly, but seems no one cares at Marvell...

It's a shame having a good hardware with so poor software support...

tiagogaspar8 commented 5 years ago

After reading every comment here I just want to say some things. First I have to say I face the same Issue, but I see it in file transfer, when sending files from my PC to my server I see speeds of 500+mbps suddently dropping to the same speed of around 40mbps, that should be a hint. Second thing I have to say is that this issue is valid for only my Intel card (8265), as my phone, a OnePlus 6 can easily achive 500+ speeds without sudden drops. Third thing, I have contacted Intel for them to try to solve this issue (?) and if @yuhhaurlin has anything for me to forward to Intel to help them solve this issue I'd be glad to do it. 😄

makedir commented 5 years ago

@tiagogaspar8 There is only one solution: Buy a standalone wifi access point and plug it into your router. I did this already monthes ago, and since then I get 77MB/s (600mbit+) speeds with my Intel 9260 card through 5Ghz!. No drops, 100% stable. This issue wont ever be resolved. I also already had contacted Intel about it 6 months ago. They ignored it and were no help too.

jukkapirinen commented 5 years ago

Could it be similar issue I had with OnePlus devices that it didn't follow up the advertised capabilities?

Especially not exceeding the packet size Max MPDU length 3895

One way to check this is to setup another AP as a sniffer (monitor interface) what can handle larger packets, e.g. ath10k.

Edit here the related issue

https://github.com/kaloz/mwlwifi/issues/295#issuecomment-391610963

tiagogaspar8 commented 5 years ago

@makedir I have already spent too much money on this router and every other device achieves very high speeds in wireless so I'd rather replace the wireless card on my PC with another one. Intel has been nagging me with this issue as I don't answer fast enough and they want to solve this issue as fast as possible. Now, I need to know if this problem we're all having is with the intel driver or with the mwlwifi firmware. Maybe the Intel driver has a bug that other AP's "ignore" and mwlwifi just can't deal with it and forces those sudden drops (?) I'm willing to test anything @yuhhaurlin wants to help fix everything.
