EA4500 WiFi TX rate issue

Keywords: WiFi Cc:

Description

recently i flushed my EA4500 router to CHAOS CALMER (15.05.1, r48532).

but i have two issues in my WiFi the first one the TX Rate is always 1.0 Mbit/s, MCS 0 and the second issue when i raise the TX power is not changed it is always stuck on 18 DB even when i tried to change the country code.

and when i try the 5Ghz it is also stuck on 6Mbit/s

Thanks in advance i hope you can fix this issue for me because i like the performance of the router and it is really reduced the latency.

Yes, I see the same thing on the N and G bands on the E4200 and the EA4500 both with the trunk build. Country code doesn't make any difference. Limit flashed in rom maybe? This router has a nice amount of juice for as cheap as it is now, but the Cisco firmware nor openwrt seem to have decent range.

The openwrt firmware does leave cisco's stock firmware (probably backdoored) in the dust.

Thanks Devs!

I am using EA4500, with the up-to-date version (Designated Driver r49035) Installed
I found the wifi driver works tricky on the TX process
ping test <1ms, loss 0%
Bandwidth test, more than 100 Mbits
But, if the traffic is low, the last packet in the router might not send to the client, only another packet arriving will trigger the packet sending, which might cause high latency, and unstable feeling, tcp connection lost.
So I guess, there might be a mistake be taken in the driver, probably forget to set a timeout method to flush the buffered packets to the client.

i don't have an issue with ipberf (bandwidth test) but there is some high latency through wireless and it is more on 2.4GHz than 5GHz but it is happened on both and i am using Chaos Calmer 15.05.1.

I'm not a coder, but is there anything we can do to assist. I believe this router does have some potential, but limiting it to 63db instead of 100db makes a huge range difference.
