A few days ago, my old Toshiba cable modem broke down and I had to get a new ******** SB5101 cable modem. My Linksys BEFSR41 network router doesn't work with the new cable modem. Resetting the network router to factory defaults didn't work. I had to disconnect the network router from my system. Yesterday, I was not able to log into the Internet and I thought that there's a problem with the new cable modem. My sister called the cable TV company but they won't send anyone out until Thursday (next week). This morning, I turned on my system and found out that the cable modem was working! While searching the Internet two days ago, I found out that some people have problems using Linksys network routers with cable modems. Do I need new network router not made by Linksys? I have Microsoft XBOX360 game console connected to the network router.
