Since installing a Linksys Wireless router (WRT54G) with my ntl cable modem I get the following:
After I boot up and connect to the internet (winxp SP2) and then try to access the web, I get an error message that tells me that †˜no connection to the internet is currently availableââ‚ ¬â„¢ and asks me if I would like to †˜work offlineââ‚à ‚¬Ã¢â€žÂ¢ or †˜try againââ‚ƚ¬Ã¢â€žÂ¢ to attempt to connect. I click on †˜try againââ‚ƚ¬Ã¢â€žÂ¢ and it uses the connection, no problem. It then works perfectly but if I don't access the web for a few minutes I get the same message. If I click on 'try again' it works OK again.
I set up the router using Automatic Configuration †“ DHCP; under which there is no †˜Keep Aliveââ‚ƚ¬Ã¢â€žÂ¢ option. The option to keep the connection alive only appears under PPPoE and PPTP.
Iâ₠¬ÃƒÆ’¢â€žÂ¢d be very grateful for any advice.
