I've been on cable broadband for years without any problems. My setup was a standard cable modem plugging directly into my ethernet port on my PC.
Recently, to create a wireless network in my home, I have added a broadband router to my setup. Now the cable modem plugs into my new routes which then plugs into the ethernet port on my PC. Generally, PC internet access is fine and my secured wireless network works great too.
However, on my PC, when I don't touch it for say 1.5hrs or so, when I return and try to access the internet I get the dreaded 404 page cannot be displayed on any website. Interestingly, my PC can still download things from the net (such as AVG updates or similar), so there is some sort of connection still there. Maybe I am losing the DNS or something meaning I cannot visit any www type of websites?
To fix the problem I have to either log off and back on windows or restart my PC. This works every time - I don't ever need to touch the modem or router.
Any help or advice would be much appreciated.
Thanks in advance everyone
