Hey Lamperter, I'm sorry if you feel like I hijacked this thread but it was in an obvious attempt to prove more can be done than just returning unsupported message. However, as the company itself is unwilling to provide firmware and everybody mention this chip variant in such a negative context there are obviously some internal reasons to keep it unsupported with silicon bug or two being used as an excuse. Most chips have some hw bugs and workarounds for the same are available, but this didn't result in dropping support for their drivers. So, you can go with this change, but it won't be that useful or required as few others who switch to different card in their router won't need it. For the rest of us 700Mbps with factory TP-Link firmware will suffice.
