I’m having problems with the wifes PC, the network has suddenly become very unstable, it will connect then soon after it will drop out and ask for the authentication key then connect again for a while before dropping out again, I’ve tried plugging in a a spare USB adaptor but that doesn’t make any difference, this problem really began a couple of days ago when we lost our network connection completely and I had to reboot the router but even after doing that I also had to reboot both PC’s before they would finally connect again my PC (Linux1) is fine but the wifes PC (lLnux2) is incredibly unstable.
Both PC’s are running Peppermint 4

I recently got a new Virgin Media Superhub which I’m finding is not so super, I can’t tell you how often I have to reboot the damn thing I should have known better on this occasion but I had already rebooted before I reported the problem on here now it’s making a fool of me.
before that I had an old Motorolla Surfboard cable modem with a Belkin wireless router and I hardly ever had to reboot especially the modem that thing was indestructible wish I still had it
Those superhubs are appalling, and Virgin know it (their forum is full of “it’ll be fixed with a firmware update” that never comes). How they can release such buggy hardware onto the masses is appalling.
Ok I thought I had this problem sorted but it’s not only not sorted it’s getting worse, I’ve tried all I know this evening but I’m getting nowhere, I thought I sorted it when I removed the PCI Wireless card and plugged in a USB adaptor and it seemed to work ok for a whilw then it just started dropping out again, also I’ve just been informed by the missus that she’s not getting emails with Thunderbird I just tried it myself and sure enough cannot connect to server even though the network icon is showing connected

OK, settle on a particular adapter and send the output I asked for earlier … so I can get the device ID’s to look for drivers, and get an idea if this is a signal strength issue.
Yes we have, same user, same physical location different PC
since the last time we went through this problem I got her another PC and since then the network/Internet has been rock solid until a few days ago when the whole network went down and I had to not only reboot the router but both PC’s had to be rebooted as well, my PC (Linux1) & Chloes PC (Linux3) is fine but this PC (Linux2) hasn’t been the same since

I’ve reverted back to the PCI card and at the moment it seems fine again but that’s the nature of the problem it could start playing up at any time, I’ve ran broadband speed tests on all 3 PC’s on the network and the results are as follows
since I reinstalled the PCI card this morning the connection has been stable and the email thing seems to be sorted out, last night it was hellish and I haven’t done anything different that I’m aware of, the only thing at the moment is the download speed which may or may not indicate there is still a problem
Just thought I post this because I don’t want to waste anyones time
I’ll just monitor it meantime, if it happens again I’ll do what you suggest
Any thoughts on the slow download speed, to be honest it’s not causing any obvious problem, you tube videos play ok although a bit stuttery on full screen ?
