Hi, 5Ghz working good, 2.4Ghz N not stable, connection shows 144Mbps during the test real speed max 5-10Mbps when I switch to Legacy connection drops to 54Mbps but I can get up to25Mbps, download speed, Upload speed is always excelent only download problem. I have the similar issue with Original firmware and with Dd-wrt, did someone had same problem ? Thanks Below is my router information. Linksys WRT1900ACv2 OpenWrt 18.06.2 r7676-cddd7b4c77 / LuCI openwrt-18.06 branch (git-19.020.41695-6f6641d) driver name: mwlwifi chip type: 88W8864 hw version: 7 driver version: 10.3.8.0-20181114 firmware version: 0x0702091a power table loaded from dts: yes firmware region code: 0x0 mac address: 00:25:9c:13:8d:f6 2g: enable 5g: disable antenna: 4 4 irq number: 49 ap macid support: 0000ffff sta macid support: 00010000 macid used: 00000007 radio: enable iobase0: e1100000 iobase1: e1280000 tx limit: 768 rx limit: 64 qe trigger number: 281366

mbit or mbyte? i mean with 54g its indeed possbible to get about 32 mbit download/upload. with 144 802.11n depending on the conditions you get about 90-100 mbit max. both values are just samples for really perfect conditions which do not exist in these days anymore

mbit, I think 802.11n has and issue, is shown 144 in connection details but speed goes to 10mbit max almost for any device...

from your description it seems like one of those typical compatiblity issue with your client device(s) so simpy bugs in the marvell firmware. the problem is just that marvell refuses to do any support for these chipsets. they do not fix bugs and ignore all problems since a very long time.

I have this problem on all my devices... To bad, would be a nice router... I'll take wrt3200 from one of my friends and test speed with it...

RomSand commented 5 years ago

Same thing on wrt3200. did someone get higher speeds on this routers on 2.4 Ghz ?

RomSand commented 5 years ago

Was told by linksys that 2.4Ghz part of the chip is broken and to return it to store )

For anyone encountering this issue, make sure you have WMM turned on (checked) on the wireless settings. Unfortunately, this will break many ESP-based IoT devices; however...
