In your main PC, open Internet Explorer, go into tools, internet options, advanced tab, and make sure that "use SSL 2.0" and "use SSL 3.0" are checked. Hopefully it works. You can google that error code if it doesn't.
Now, with the other problem with the router, I'm not sure what your set up looks like. It is difficult for others to attempt to diagnose the symptom. Are all three computers plugged into the router, then the router to broadband internet? Or, is your main PC connected via phone modem giving your other computers internet access through your ethernet port? Please be more specific.
Can any body offer any advice to solve a problem I'm having.I am trying to set up a wireless network system & have come to a standstill. I have got my main computer on line but cannot get my other 2 working. My router is an SiS 900-based fast ethernet ad & my ISP is AOL. My 2 main problems are once on line with my main PC & I try to log on to MSN I get an error code 81000306. I also cannot get onto quite a few other sites such as Ebay etc. My other problem is I cannot figure out how to change my IP addresses on number 2 & 3 PC's as I think thats the reason they will not work on my router.Any help would be most welcome
