Random & Consitant disconnections

you see i dont understand why it's to do with my provider though. Like i said it is ONLY my pc that's effected out of a total of 8-9 devices online at any given time. i even went close range, i'm talking about 10 foot from the modem and im still disconnecting. aslwee as going around and turning the wifi off on as many devices as possible yet still my pc is the one that constantly disconnects. I went and i brought a brand new wireless card and even that didnt fix it as well as wiping my c drive and reinstalling windows. The modem is also brand new it's an EE brightbox 1 (r) or something even though they were supposed to send up a brightbox 2. regardless of that the problems only started happening when we got this new modem. I just want to be able to get on the web again for more then 20 minutes but noone anywhere not even my providor has answers. (EE is the best coverage we have where i live and its a very off the grid area so network coverage isnt the best) This problem has never happened and i've lived here for almost 2 years now and suddenly it decides too. im not sure if its the windows update not liking this modem or it's just the modem being terrible... even though it's technically better then my old one

Hi there
Afraid I'm out of ideas now ---

As a last resort totally switch of the cable box (not just re-set but disconnect from mains completely) and do a complete box reset --there's usually a button you have to hold in for 10 secs or so when switching it back on again.

(Before you do this remember any passwords / settings though).

Also I don't understand why you've enabled any proxy settings -- shouldn't be necessary. I assume you get connections if you connect directly to the box with a LAN cable --if you don't have any LAN connections on the computer just use a USB-->LAN connector -- very cheap in Maplin in UK. This will at least test if there is another problem with your computer.

I still somehow suspect the set up is at fault though.

One final idea -- try a Wifi extender -- you can fiddle around with this to set different channels etc without disturbing the main router / cable box. It will have a different SSID - usually like SSID-EXT where SSID is the original name of your main wireless network.

This will set you back though about 50 - 70 EUR though (not sure of the GBP-EUR rate at the moment -- seems to change hugely every time a Politician opens his / her mouth !!).
