I'm having a problem with my network since last week - my desktop internet access slows to un-usable speeds & the modem is dropping connection more often. Wierdly, wireless performance is as expected (although obviously affected by the drops too). Might be coincidence but this coincides with some building work that included some new sockets....
Here's a quick network map:
Obviously I initially suspected the homeplugs/wiring since this has had some changes.
I'm no electrician, so I'm ruling out simple things first - changed cat5 cables on homeplugs & unplugged all other components around them. No change.
I'm getting consistant 4/5ms pings to the router from the desktop, even during the incredibly slow internet performance on desktop so I'm now suspecting the router. A download test between netbook (WiFi) & desktop (ethernet) suggests that the desktop downloaded the first few K really quickly & then died a death (netbook downloaded as expected). On the offchance, I have rebuilt the desktop OS from Vista64 to Windows7Ultimate64 to rule out OS issues (its slowed down a bit recently & needed a rebuild). The netbook dual boots XP & Windows7 - both fine.
I'm thinking the next steps to diagnosing where the issue is are:
This should point the finger at either the desktop, homeplugs/wiring, or modem router. Other ideas/reccomendations to help diagnose the problem are welcome.
Thanks

Here's a quick network map:
- BT broadband (or similar - arranged through work @ 3.5Mb doanload, 300kb upload. Pretty stable.)
- Netgear ADSL Wireless Modem Router (in kitchen) connects via cat5 cable to...
- XyZel Homeplug 200mb connects via Mains circuit to...
- XyZel Homeplug 200mb in spare room, connects via cat5 cable to...
- Netgear 4port hub connects via cat5 cable to...
- - Desktop
- - Laptop (occasionally connects wirelessly to router)
- - Laptop Work1
- - Laptop Work2
- - Netbook (connects wirelessly to router)

- Connect netbook to spare room hub & test internet via ethernet.
- Connect netbook to router directly & test internet via ethernet.
