Very Slow 5G WiFi Connections for Laptop and Tablet - MAC80211 version 10.3.4.0-20180330

ejouellette commented 6 years ago

Hi Everyone,

I've been successfully running David's LEDE distributions on my Linksys WRT3200ACM router since Fall 2017 with no issues until Feb 24, 2018 (r6302). The last firmware that worked well for me is r5917. Every version after that, including the latest r6868, causes my WiFi connection for both my laptop (HP Envy 17) and Tablet (Samsung Galaxy-Tab-A-2016) to come to a crawl. I have very strong WiFi signal (computer in same room as router). When the adapter first connects, it says it's connected at 433Mb/s speed, however, in the LEDE GUI wireless status, it shows under Rx / Tx Rate: 18.0 Mbit/s, 20MHz 13.0 Mbit/s, 20MHz, VHT-MCS 1, VHT-NSS 1 Yuk!! Reverting back to r5917 fixes everything. My laptop is running Windows 8.1 Pro with Intel Dual Band Wireless-AC 3160 card with latest drivers. I've played with router and adapter settings and channel frequencies. Nothing helps.

Here's a brief summary:

Build | Download Speed (Mb/s) | Upload Speed (Mb/s)

5917 145+ 16 6302 <= 2 12 6520 <= 1.3 <= 6 6565 <= 1.2 <= 8.6 6868 <= 2.4 <= 9

What should I try next? I believe this issue is related to the MAC80211 WiFi driver / fw for the Marvell 88W8964 chip. Any help would be much appreciated! Thanks, Ed

My two cents:

50/50 Mbps FFTH internet connection
WRT3200ACM + LEDE 17.01.4 + mwlwifi fcaea79
Xiaomi Mi A1 + Android 8.0, connected to the 5GHz band, a couple of meters away from the router
SpeedTest Android App, latest version, and default options
Results: 14ms ping, 40ms jitter, 45.9 Mbps down, 46.4 Mbps up

I can saturate the internet connection at 45Mbps using the 5GHz band (far from the speeds reported here); however, I have not done any tests recently using only internal traffic. If you feel I can be of any help, just tell me.

yuhhaurlin commented 6 years ago

I think you need to list version of mwlwifi instead of version of LEDE.

ejouellette commented 6 years ago

Yes, sorry about that. The last version of mwlwifi that works for me is 10.3.4.0-20180118-1 (kmod-mwlwifi - 4.9.77+10.3.4.0-20180118-1)

With that driver, all my 5GHz connections work great, including my HP Envy laptop and Samsung Galaxy tablet. Here are some results: wlan0 ... Envy-TS17 -70 / -96 dBm 54.0 Mbit/s, 20MHz 433.3 Mbit/s, 80MHz,VHT-MCS 9, VHT-NSS Short GI

wlan0 .... android-xxx1 -76 / -96 dBm 150.0 Mbit/s, 40MHz, MCS 7, Short GI 150.0 Mbit/s, 40MHz, MCS 7, Short GI

wlan0 ... Galaxy-Tab-A -72 / -96 dBm 54.0 Mbit/s, 20MHz 292.6 Mbit/s, 80MHz, VHT-MCS 6, VHT-NSS 1, Short GI

Comcast speed test with this 10.3.4.0-20180118-1 mwlwifi driver has result: 160 Mb/s down, 12 Mb/s up (I have 150 Mb/s service). With all newer mwlwifi driver versions, Comcast speed test is < 10 Mb/s down (16x slower!), < 10 Mb/s up for 5GHz devices.

@eduperez: I also tried LEDE 17.01.4 + mwlwifi fcaea79. It also has very slow result (Comcast speed test is < 10 Mb/s down), most likely due to 10.3.4.0-20180330 mwlwifi driver.

yuhhaurlin commented 6 years ago

Please user iperf to test throughput between router and client.
Please swap firmware to see if this issue is related to firmware (/lib/firmware/mwlwifi/88W8964.bin).

eduperez commented 6 years ago

@2Torr I just tried to use iperf3 between the phone mentioned above and a desktop PC connected to the router by an ethernet cable, and I'm getting about 250 - 275 Mbps with fcaea79. Will try with other wireless devices later.

ejouellette commented 6 years ago

@eduperez: I have extreme slowdown for 5 GHz WiFi connections only for 2 of my wireless devices: HP Envy-17ts laptop Samsung Galaxy-Tab-A-2016

all of my other 5GHz connections (e.g. android phones, Samsung TV, etc.) seem fine with the latest fcaea79 mwlwifi driver.

eduperez commented 6 years ago

@2Torr I'm trying to get my hands on more 5GHz devices to test

jukkapirinen commented 6 years ago

I got new phone OnePlus 6 and have problem with upload speed from Phone to wrt1900acs. Because not sure if it is issue with the phone or the AP I submit bug report also to OnePlus https://forums.oneplus.com/threads/wifi-upload-speed-very-slow.838296/

This happens when roaming from Archer C5 to wrt1900acs and slowness is only on 5GHz. 2.4GHz is ok. (Edit, same behaviour with or without roaming FT / 802.11r is enabled or not) Other way around no issue, so when roaming back to Archer or other APs speed is OK.

Also if I just restart WiFi on the phone, speed is OK again.

I'm at r7020-43d70a7a9d 10.3.4.0-20180330

Before I was in r5329-769e1bac7b 10.3.4.0-20170810 and it had the same issue

While running iperf it is associated like this, either if iperf running slow or not.

64:A2:F9:xx:xx:xx  -62 dBm / -89 dBm (SNR 27)  70 ms ago
        RX: 866.7 MBit/s, VHT-MCS 9, 80MHz, VHT-NSS 2       451 Pkts.
        TX: 702.0 MBit/s, VHT-MCS 8, 80MHz, VHT-NSS 2       350 Pkts.
        expected throughput: unknown

Here iperf, first is from phone to Server in LAN, second from Server in LAN to phone.

In station dump only difference what I see when it is slow that preamble is short. All my other devices connect long preamble. Is it possible to force to long for testing?

Here steps to reproduce the issue 100%

AP1 = Linksys WRT1900ACS, Openwrt r7020, mwlwifi 10.3.4.0-20180330 AP2 = Archer C5 v1, Openwrt r7021 Phone = OnePlus 6, OOS 5.1.5

Have same SSID configured on both APs on 5GHz and place so that they overlap a bit.

Connect Phone to AP1. Upload speed is OK.
Walk near AP2 so it gets connected to it. Upload still OK.
Walk back near to AP1 so it gets connected to it, upload speed is very bad.
Switch phone wifi OFF ON to reconnect to AP1, upload speed is good again.

jukkapirinen commented 6 years ago

Any other logs I could collect? I have this issue only with wrt1900acs..

jukkapirinen commented 6 years ago

I monitored the AP wlan interface while roaming, seems OnePlus 6 capabilities gets changed while roaming. Could it cause WiFi Driver to confuse? I have also collected tcpdumps from both AP and Phone, but not sure what to look from them. At least there is a lot of TCP Dup Acks, TCP Re-transmissions and TCP Previous segment not captured after roaming.

Attached screenshot below for the capabilities, left side association and right side reassociation.

Summary: HP Envy-17 device experiences ~10x slower download, ~2x slower upload speeds (between device and router) with latest mwlwifi 2018-03-30-fcaea79a-1 driver, compared to mwlwifi 10.3.4.0-20180118-1 driver. Samsung Galaxy-Tab-A-2016 device experiences only 5% slower download, ~25% slower upload speeds now (after software update), even though it still associates with router as: 54.0 Mbit/s, 20MHz; 6.0 Mbit/s, 80MHz

i can confirm that something is weird, i never had wifi issues for a long time on 3200acm, i think, the last commit did this. i am on lede 17.01.4, totally something cannot register itself, or wifi goes away, and must be the last commit, i think, before always working.

Tested with OnePlus 5 with OOS 5.0.4 it has the same issue...

@p3x-robot I'm having WRT1900ACS, no issues for long long time with WiFi, until now with OnePlus 6 (and OP5 seems).

I think there is something wrong with the OnePlus WiFi also as you see the capabilities gets changed when re-associating. But how is ath10k handling it?

Tried to disable beamforming also, didn't help.

Edit: upgraded OP5 to OOS 5.1.2 and still the same

p3x-robot commented 6 years ago

just, i have no idea, when it started going wrong, because, i was rebuilding every time, i saw a new commit, that's sad... but in the last weeks, it was going bad. sometimes, i couldn't find the wifi, sometimes, even after reboot. i will shoot the error log, if it goes bad again.

p3x-robot commented 6 years ago

though on android i can hit 200-500 mbits. so weird, but i sometimes not working with mwlwifi latest.

p3x-robot commented 6 years ago

i think hostapd cannot connect to AP, that's what happens sometimes, i remember, but i will find to log once it goes bad again ...

Attached network captures for slow iperf upload from Phone to LAN. Taken from AP and from phone.

No one else has OnePlus 5 or 6 could test this?

yuhhaurlin commented 6 years ago

@2Torr You can wait for future release to check it again.

yuhhaurlin commented 6 years ago

@bbogey If stock firmware has the same issue, please report your problem for stock firmware.

yuhhaurlin commented 6 years ago

@p3x-robot I have no idea what the problem you have.

p3x-robot commented 6 years ago

sorry,it was stable for long time, then it was weird, but given we have like 50 devices in the apartment, i have no idea.

@yuhhaurlin i think you are awesome, i was questionig like others as well right now... no problem at all. ciao

jukkapirinen commented 6 years ago

@yuhhaurlin I don't think they bother this old device. I'll try check with OnePlus as the issue is only with OnePlus devices. Because it will most probably never be fixed their end either I ordered new AP with ath10k and maybe return the phone also...

yuhhaurlin commented 6 years ago

@bbogey The strange thing is that reboot the phone will fix the problem. Unless using sniffer to capture air packets, I have no idea how to check it.

jukkapirinen commented 6 years ago

I have the mon capture. Not sure if it would help.

No need to reboot the phone. After initial association speed is good. Problem is only after re-associating back to wrt1900acs and only with 5GHz and only with AC.

Here again the screenshot from mon capture. Left side is the initial association and right side re-association https://user-images.githubusercontent.com/9322054/40606797-3d96d568-626f-11e8-94b4-c5542354008f.PNG

Looking at your capture, I noticed a couple of things:

c2:56:27:cc:58:95 is not a valid MAC address. First thing I noticed is the OUI wasn't typical for Belkin, and when I did a lookup, there is no vendor assigned c2:56:27. This is very strange.
The capabilities you've got highlighted are in the assoc req packet - ie the contents of the packet going from the device to the AP. In other words, you're highlighting an issue with your device, not anything to do with mwlwifi.

In short, while I believe you may have an issue, the information you're posting hasn't indicated anything having to do with mwlwifi, the MVL8964, the firmware, the WRT1900ACM or WRT3200ACM. And, I'd posit, all the information in this thread points to other more likely sources.

jukkapirinen commented 6 years ago

@derosier it is valid address. For different APs I have created custom MAC addresses.

Yes screenshot I have provided to show up the odd thing I noticed from phone assoc request like wrote above. So phone capatibilities are different in association and re-association. The thing is that wrt1900acs together with OnePlus does not work together. Archer C5 (ath10k) works fine with OnePlus. And with any other device combinations no issues...

Kherby commented 6 years ago

Same problem here, 5ghz wifi speed is very irregular, drops often down to 3-5mbps and stays there, my wifi card (Intel AC8260) shows 390mbps and Luci shows 6.5-27mbps @20mhz. I cant enjoy my WRT3200acm because of the wifi performance, it's realy frustrating !!

Pls fix this, it's ridiciolous how bad this marvel wifi is... Sometimes i do think my WRT3200acm has a faulty wifi module but it seems that im not the only one with these issues.... :/ My router from 2012 is performing way better and it really shouldn't be like this and that's not a joke.

yuhhaurlin commented 6 years ago

@Kherby @bbogey's issue is related to WRT1900ACS and it happened after reassociated. What problem that you want me to fix? Please run iperf and show me the number.

jukkapirinen commented 6 years ago

And one more thing In hostapd-phy0.conf there is preamble=1 And in AP probe / (re)assoc response

.... .... ..0. .... = Short Preamble: Not Allowed

For OnePlus 6 in station dump it shows after associated:

preamble: long

And after re-association

preamble: short

For any other device it isn't short ever.

But I don't think it matters as it is used only for b and g standards?

Kherby commented 6 years ago

@yuhhaurlin I would love it if you finaly would fix the Wifi firmware, so my 5Ghz doesnt drop to 3.5-4mbps anymore when downloading something over the internet. The problem will happen on my WRT3200acm as well, that's why im writing here. Why do u want me to run iperf ? It's clear that the wifi troughput is completely out of line.... If i switch to my other Wifi AP and i'm getting full speed immediately, if i reboot the WRT3200acm im getting full speed as well for some time....

Or there any Magic wifi config that will work/fix the problem ? I'm running iperf later, can't access any client at the moment as im not at home.

yuhhaurlin commented 6 years ago

Please use iperf and show me the number.

Kherby commented 6 years ago

I'll do that !! I guess u want 5ghz WLAN >> LAN test right ?

jukkapirinen commented 6 years ago

Ok contacted Linksys.

http://community.linksys.com/t5/Wireless-Routers/After-reassociating-to-wrt1900acs-with-OnePlus-5-or-6-upload-is/m-p/1317289#M35242

Edit: They called me today but as I'm the only one reported the issue, at this time it probably goes nowhere. They will call again after one week.

Here's the source for OP6 wifi driver and it is pretty recent fork

https://github.com/OnePlusOSS/android_vendor_qcom-opensource_wlan_qcacld-3.0/tree/oneplus/SDM845_O_8.1?files=1

If someone has Pixel or Essential or some other device with Qualcomm chip and Oreo 8.1 could you please test if you could reproduce the reassociation issue.

jukkapirinen commented 6 years ago

Is it normal that client acts as beamformer also? I only read that it is used in APs to send beamformed frames. Edit: looks like ipad Air 2 support beamformer also, no issues with ipad.

jukkapirinen commented 6 years ago

Got Netgear r7800 and bridged to wrt1900acs directly on LAN port. No issues with r7800 in speed after reassociation.

Next maybe I'll take mon capture from both at the same time and see if something found. Also will compare with earlier captures. Edit: looks like monitor can capture only broadcast packets even I'm at 10.3.4.0-20180330

In mean time OnePlus has corrected the Short Preamble and VHT capabilities in reassociation, not sure what other changes they did, but no help in this issue.

jukkapirinen commented 6 years ago

After reassoc I started upload from the phone via wrt1900acs.

Here is left monitor capture from wrt1900acs, right from r7800. I don't see all frames in wrt1900acs capture what I can see in r7800.

The missing packets are repeteaded elsewhere also. Common for all missing packets is that the length is 4684. Could the issue be with this limit what Phone does not follow now? Max MPDU length: 3895

sniffer missing packets from linksys

Here attached the missing frames

jukkapirinen commented 6 years ago

Looks like the culprit was these too large frames sent by the phone. OnePlus made a new version for me and there is no these large frames anymore and it seems to fix this issue.

ghost commented 6 years ago

Sounds like router firmware/wifi driver needs large frame support.

Not sure about that, wrt1900acs work very fast and responsive even with the smallest frame size. But yes for misbehaving clients it would help.

@yuhhaurlin

On my wrt1900ac I'm haveing same problem. :-(

yuhhaurlin commented 6 years ago

For WRT1200 or WRT1900 (which uses 88W8864), the maximum A-MSDU size is 3839.

yuhhaurlin commented 6 years ago

I wonder if I can close this issue?

yuhhaurlin commented 6 years ago

Bit 11 (Maximum A-MSDU Length) of HT Capability Information field:

0: 3839 octets. 1: 7935 octets.

Bit 0..1 (Maximum MPDU length) of VHT Capability Information filed:

00: 3895 octets. 01: 7991 octets. 10: 11454 octets.

A VHT STA that sets the value of the Maximum MPDU Length subfield in the VHT Capabilities Information field of the VHT Capabilities element to indicate 3895 octets shall set the Maximum A-MSDU Length in the HT Capabilities element to indicate 3839 octets. A VHT STA that sets the Maximum MPDU Length in the VHT Capabilities element to indicate 7991 octets or 11 454 octets shall set the Maximum A-MSDU Length in the HT Capabilities element to indicate 7935 octets.

The length of an A-MSDU transmitted in a VHT PPDU is limited by the maximum MPDU size supported by the recipient STA (see 10.13.5).

yuhhaurlin commented 6 years ago

If you use WRT3200ACM (88W8964), you will not encounter this kind of thing.
