Hello,

I need help to resolve WiFi connection issue which happens sometimes.

Some times I observed WiFi connection issue with mt7603e driver over 2.4 Ghz AP.
When device is in use, suddenly all 2.4GHz connected stations gets disconnect and later unable to connect STA devices to AP unless device gets reboot.

Seems either mt7603e driver does not respond or mt7603e chip-set.

Following are the logs and observation:

root@OpenWrt:~# iwpriv  ra0 stat
ra0       stat:
Tx success                      = 0
Tx fail count                   = 0, PER=0.0%
Rx success                      = 0
Rx with CRC                     = 63035, PER=0.0%
Rx with PhyErr                  = 0
Rx with PlcpErr                 = 0
Rx drop due to out of resource  = 27256
Rx duplicate frame              = 0
False CCA                       = 0
RSSI                            = 0 0 0
TX AGG Range 1 (1)              = 0
TX AGG Range 2 (2~5)            = 0
TX AGG Range 3 (6~15)           = 0
TX AGG Range 4 (>15)            = 0
AMPDU Tx success                = 0
AMPDU Tx fail count             = 0, PER=0.0%
WPS Information:
Enrollee PinCode(ra0)           25150087

Enrollee PinCode(ApCli0)        04178569
Ap Client WPS Profile Count     = 0

efuseFreeNumber                 = 26


When issue observed I see "Rx drop due to out of resource" continue incremented and "Tx success" is stable.

Does it is wifi driver issue or mt7603e chip issue ?
Because "Rx drop due to out of resource" is read from chip register set.

Does any one observed similar issue ?

Thanks,
Amul Patel

For mt7603 you want to follow snapshots/ master, to get the most current mt76 code, which is still under heavy development.

The discussion might have continued from here.
