This is a weird one and difficult to explain. I have spent roughly 3 days trying to find a fix for this but it seems that nobody has experienced the same problem as me in quite the same way.
I have just purchased a new machine. Built in wireless (802.11n Wireless LAN Card + Realtek PCIe Family Controller) with two aerial things at the back.
The internet is completely sporadic after five minutes of being on. If I re-boot the machine for those first 5 mins it works perfectly but then just goes weird. I can load some webpages instantly, others just can't connect at all, they time out... - but if I am streaming in another tab the video is never interrupted and continues to download at reasonable speed despite the connection problems on the other page? What?
I am at a loss now. I rang my ISP Tech Support but the guy on the phone exhausted all avenues of investigation, most of which I had tried myself before-hand anyway, before giving up and telling me that he had no idea whatsoever.
I'm really gutted because I just blew £400 and I can't send it back unless there is a 'fault' - and there does not appear to be any problems at all with my machine - the connectivity is stable and fine, I just can't load webpages unless the browser wants to at that particular moment.
Any suggestions or thoughts would be massively appreciated. I NEED to get this sorted.
