In my other thread Netgear DGN3500B Wi-Fi download speed is slow I was advised to create a new one just for this error.
The kernel log of my Netgear DGN3500B is full of
eth0: tx ring full
which leads to slow WiFi speeds.
This issue has already been solved on xrx200, but not on xway.
Maybe someone can port it to xway, too.
What´s really strange is that @vasilis74 has nearly the same device, but not the B variant and the issue doesn´t show up at his/her device.
For more info check my other thread,
I hope anybody can help.
