its not able to gain an IP address , please note that i have 2.4GHZ only and please note when i used my old linksys router the device worked FINE so definitely there is something i need to configure in the router to make it function
please help as im not that expert in configuring the WRT

screeeeeem · April 21, 2020, 5:27pm

to add on it shows under associated stations but its not able to gain an IP address

please advise

Have you enabled legacy mode?

screeeeeem · April 21, 2020, 7:34pm

Yes with no luck

This is probably a device based on a ESP-8266 chip, that are incompatible (or the other way around) with your WRT3200-ACM router. You can read about his issue here:

screeeeeem · April 22, 2020, 2:49am

eduperez , you are super !!!!!
when i disabled WMM it worked like a charm , my question now is what is WMM ? is it really worth using it ?
PS : im still testing my other devices to make sure no impact is there

thanks a million !!!!

slh · April 22, 2020, 2:51am

WMM is a hard requirement for 802.11n and above, if you disable it, you effectively limit wireless throughput to pre-802.11n speeds (54 MBit/s).

screeeeeem · April 22, 2020, 2:54am

Hi slh
i dont believe that is true , my speed test shows more than 13 MBps and in the old router i just checked and that WMM feature isnt there even

slh · April 22, 2020, 2:57am

I haven't gotten my math checked recently, but I think 13 MBit/s << 54 MBit/s.

WMM is part of 802.11n (and upwards), if your (old) router exposes a knob to disable it or not.

screeeeeem · April 22, 2020, 3:03am

i thought you were saying bit not byte , my bad
im not worried about that as my MAX speed is 25MBps so it wont make any difference at this stage , im just checking my streaming services to confirm the resolution

I need to disable WMM on OpenWrt for an Epson printer, the same exact problem, connects but doesn't recieve an IP.

This happens on a few different Atheros devices I've tested while running OpenWrt, but on factory firmware the printer is fine with WMM enabled.

It doesn't seem to be a incompatibility problem, at least in my case.
