It's not until a problem like this comes about that I realise that I really don't know much about wifi.
Client had a simple 54mbps G router previously. system changed and we put in a TP-link 901ND AP.
It is around 4m away from where it was previously. Wireless keeps losing connection randomly and going really slow. It's an n router. I've scanned around and tried to pick channels which are not being used by neighbouring network. I've tweaked it so its only using 20mhz channel width instead of 20/40. I've tried to move it to BG/G only/N only etc... with no real luck. Today I put it on G only and put the speed down to 54Mbps - didn't do a whole lot. I've replaced the device so I know it's not that.
It's a 2.4GHz band AP. This is where I scratch my head and a deeper understanding of wifi is required.
I suppose I have 2 questions here:
1) anyone got some suggestions?
2) anyone got some links/vids which explains the different standards and how channels work and how it works when they use multiple channels at once.
Thanks in advance.
