Some days is OK, like now and other day just forget about it. My setup is TimeCapsule (router/base station) running in 2.4 G mode, 2 widows laptops in G mode, and a older Airport Express 'G' standard. Today, I would say the network between the TimeCapsule is OK. I have a emac connected running tiger and it surfs alright but downloads are just slow (10k/sec downloads). Streaming itunes music works OK, but just forget about video podcasts. My laptops can all surf OK to, but again the WiFi is not great. Somedays however nothing seems to work, iTunes is very glitchy (rebuffering every 5-20 seconds), And surfing is just painful. Yet upstairs plugged into the router the net is up and everything is good. Now I work from home a lot, so I know using the microwave interferes with the G network. But these problem just seem to happen and it's either a OK day or everything just sucks. Short of spending the time and effort of going to 'N', how will I know what the cause of these problems are? My Timecapsule is upstairs in the Hall, the house is open concept maybe max 50' between devices my Signal / Noise is -60/-90 most times. I'm also thinking to going with the powerline modems. Any thoughts?
