I was wondering if people could please give me a few pointers to troubleshoot some internet/network issues I'm experiencing in a house I just recently purchased.
I have Orcon ADSL. My network is both wireless (for two iPhones and one iPad) and Ethernet over power for two desktops, a HTPC, two Xbox 360 (used for Media Center extenders), and one PS3.
The Orcon Genius router is on the top floor next to the phone outlet. The HTPC is also on the top floor, with one of the Xbox's on the floor directly below it in the master bedroom. Performance (network, not internet) seems to be very good. On the same floor (it's a three story place) are the two desktops. Internet to them is very flaky. On the ground floor (in my mancave ) I have the other Xbox as a Media Center extender, and a PS3. Network performance to that Xbox is poor at best. The PS3 hasn't had much attention thus far.
Most things point to poor network performance, but the internet doesn't seem 100% either. What steps can I take to try and pinpoint where the issue(s) lie? Are there some basic tests I can do?
Any help would be appreciated.
