did not have the problem when on Cisco router 25Mbs - switched to 50Mbs - got Thomson modem and have nothing but problems since then. Called UPC many times, reported the problems, i always got stupid bimbo on the phone calling me trying to convince me this is my computer problem. We have 5 laptops in the house, different makes and models, 4 different operating system (Windows 7, Windows Vista, OpenBSD and BackTrack Linux) and they like stubborn donkeys keep telling me, this is computer/laptop related problem. Sometimes it drops few times in 5 minutes, sometimes laptop with BackTrack Linux connects to the modem then it's been disconnected...then it connects again - gets drop off again - and this play lasts for the whole night sometimes. Next day - it is other way: laptop BackTrack Linux keep connected while Windows 7 keeps disconnected. OpenBSD is different since it monitors the connections and when loses the connections it resets the wireless card and ask DHCP for new IP number again, so the only thing you see is the wireless card indictaror blinking sometimes. For me it looks like this is wireless router problem, since it loses the strenght of the signal sometimes down to one bar - even when my laptop is 3 meters away from the router. Then a second later the signals jumps up to 5 bars..
UPC is ignoring the problem all the time. They have stupid bimbos working with them as Customer Service Consultants and they completely ignore what I am saying about the laptops; they keep repeating like a parrots: this is your laptops related problem; when I asked them - you want to tell me, that 5 laptops with 4 different operating systems are having the same problem - they just keep saying: This is problems with your computers not the modem since we did check the modem and it works ok.
Today i lost my temper and wrote them they are stupid thick donkeys and i want to see a technician in my home, someone who knows the stuff. I have network diagnostics files (on Windows so they could not tell me they support only Windows based computers) I want him to look at them (can't send them since they not accept attachments to emails and the files are 250MB one and 250MB another one) both files contain all registered issues with network while it worked, when it stopped, what happened then and what happened when windows was fixing the connection, all this kind of technical stuff.)
As for now it seems like the only solution to this is to turn off and on the wireless card itself (since to be honest this is the only thing that Windows is doing when fixing this problem automatically) or - i f you have a wireless switch beside the keyboard (like my HP has) just press it to disconnect the wireless and press it again to connects it again. It will negotiate the IP address with the modem/router again and it will work...at least for some time. It looks like the modem has problem with lease time for DHCP IP address it sends to the computer and then something is not OK with it when computer tries to renew the lease time...it just got - i do not know to call it - half rejected and wireless connections stalls then.... most of the time with 'Limited Access" information. Sometimes when you open Wireless Center (or something that has similar name) it shows exclamation mark on the connection between the computer and router AND red 'X' mark on the side of router/internet side...sometimes it shows just the 'X' mark on the router/internet side and sometimes just the exclamation mark on the computer/router side..... the side it shows the problems varies. But the outcome is alwas the same: computer can't connect to Internet.
I am tired of UPC and this problem. They just keep ignoring me as a customer and keep lying to me that this is not modem/router related problem but problem with my computers.... yeah, my arse... - 5 of them at random loose connection - every day different one...
And another thing - UPC has new meaning for english word: UNLIMITED which NOW measn UNLIMITED = 250GB
For me - technically - it is still LIMITED even while the limit is really high, it still has a cap on it, so it is LIMITED in some way...or maybe I do not know english good enough
Cheers. Keep pushing UPC to fix it or to change modem. When I had Cisco 25Mbs modem - it run like a charm. actually - it was even faster then it is on 50Mbs now (when I am able to connect to the net at all) where I have never had faster speedtest result than 29Mbs... In fact most of the time i have 17Mbs and there are times when i can't even pass the test since the connection just is so slow... And i am paying for 50Mbs.. Someone is make fun of me i guess.
Sorry for mistakes..... English is not my mother language but i hope you can figure out what i am talking/writing about
