Ok, I am running winXP service pack 2, i am running Comodo firewall pro, AVG Free (updated daily), AVG Antispyware. AVG Free runs scans daily at midnight and have found nothing, the last anti spyware scan came up with nothing serious, just usual cookies, I also run C Cleaner (which is updated regularly) every time i am finished surfing the net to get rid of all rubbish left behind. No i haven't read the changes to the updated nVidia drivers. I only ever have the minimum programs running since i play online games. Anything that runs in the background slows things down. I know this machine is pretty new but its a habit i have from when i had a POS pc. I wouldn't have thought the router would be the problem since i don't have to restart the router to get my connection back. My Router/modem is a Dynalink RTA 1335, 4 port hub / ADSL modem. My computer is the only one running on it at the moment. I rarely have 2 computers running on it and this one seems to be the only one having connection problems on it ever. I updated the firmware for the router a few months ago, they don't update it very often. What am i checking in the router configurations for exactly? Is this router provided by your ISP? No. Is it also your DSL modem or is that a separate part? Yes it is the modem too. Are other computers connected to this router as well? No. Do you connect to it with an ethernet cable or a wireless connection? it is a cable hub not a wireless one. Can you ping the router? I havent tried pinging the router when the network goes down, i will try next time it does. If you try to renew your IP address, does it give you an error? i have had an error several times when trying to reconnect but i cant remember what it is. What is the make and model of this router? Dynalink RTA 1335 What version of Windows are you using? i have windows home edition, 32 bit version even though the system is a 64 bit system. I checked updates an hour ago and there was nothing that had anything to do with the network. Only Windows Malicious Software Removal Tool - September 2007 (KB890830) and Root Certificates Update.
