Hey Guys, I have an issue here that hopefully you can help me with. I have a two seperate cable lines coming into my apartment. When AT&T installed my broadband I used one of those lines for just the cable internet and I left the other one for TV. I installed a tv tuner awhile back and with a 1 GHz splitter everything was fine. This was atleast 6 months ago. Yesterday I go to get on the web and the modem lights arent all on. I check the connections and they're fine so I take the splitter off the line and go straight into the modem and my internet service is back again. If I unplug the cable from the modem and go into the tv tuner card I get TV. At this point I know this service is fine so I figure the splitter burned out. I test the splitter by plugging my tv tuner into it and then to the wall and I have tv. Its a 2 way splitter and both sides test out fine. I dont know what the issue can now be.
Could my modem be on its way out? I have a Motorola SB4100. Could the splitter not be working correctly? I figurerd if the tv is working then the splitter is good. Also, are there special splitters to get? My friend just had broadband installed and they put in a splitter that was -3.5db and a had a AT&T sticker on it. The splitter I have is -4.0db and is just a standard splitter I picked up at Home Depot.His internet is working great and his tv quality is excellent.
Thanks guys for reading through this and lending your advice. One thing as well, how do you do a line quality test? I see some of you post these results in your questions.
