Here is the rundown: In mIRC/MSN/YAHOO/AIM I get disconnected randomly. I may be in a middle of a conversation in MSN and it will boot me out. In mIRC I may get BLOCKS of information (like 5 minutes worth) in approximatley 2 seconds, or just get disconnected. I also cannot download anything above 20mb. It will stop at 5mb, 1.9mb, 18.5mb (totally random). I currently have Comcast HSI. I run a Motorola Surfboard 5100 cable modem, plugged into a Linksys BEFSR41. Both cable modem and router are BRAND NEW. Silly as it may seem, this is the 3rd router. We had a BEFSR41 before, but it would "die" on us, about once every other day, until we unplugged it, and replugged it in. Before this, we had a netgear router, which worked flawlessly, BUT COULDNT send e-mail. (Strangest thing, could GET e-mail, but couldn't SEND e-mail. EVEN THOUGH THEY BOTH USE THE SAME MAIL SERVER. I could even telnet and ping the outgoing mail server. Tried in outlook, firefox, mozilla suite, etc. E-mail keeps me in business, so I switched to that BEFSR41. So it seems I just cannot get it right. I just purchased a Cisco uBR904 router, but I cannot get it configured correctly to do what I would like, so will probably be putting it up for sale. Now, the Motorola surfboard 5100 is about 1 month old. The "new" BEFSR41 is 1 month old. Obviously this combination is not working. I DO NOT CARE HOW MUCH IT COSTS, I want a router that will work flawlessly with SB5100. I want a router that will connect all "six" computers successfully without any problems. Is it just my luck. Could there be something absolutely stupidly wrong with settings or something lame? I have spent 15+ hours with linksys tech support, and 5+ hours with comcast, with no avail. Comcast says the same thing "if you can plug directly into the cable modem and there isn't a problem, then we cannot help you, it is your router." Any suggestions please as far as combinations go. I would greatly appreciate it!
