Problem with WiFi driver in arch linux

Hi everyone

I've been trying to solve a problem with my arch (endeavour) instalation and wanted to know if anyone here can help

Everything is working well, excepting the WiFi connection. It is extremely slow, sometimes disconnecting from the network, and in the task bar, the WiFi icon shows that the signal strength is weak, although the router is in the same room. Switching between r8168 and r8169 as recommended doesnt work. Any ideas?
