Splitter issues

Just had xfinity service installed a few days ago. Initially didn’t have a tv receiver for my downstairs tv, but have since added one. That outlet is also where the gateway is connected so I had to add a splitter (xfinity issued) in order to connect both the gateway and x1 receiver. Now internet is lagging in my son’s room which is the furthest point from the gateway. I can only assume this is due to the newly installed splitter. Is this a common occurrence, or is there something I can do to improve the signal to my son’s room?

Quick answer, No. From what I understand from your post you had to add a spliter to the "main" Coax in the wall, one for the Cable Box and the other for the Router/Modem?. The real issue is it could be several things, but luckily it is easy to find out which it is. First, how large is your house? Standard single home size or less and the router should cover it without lag. This is what I would do. Use the same Device for these tests*. Download SpeedTest.net on your phone. With the setup as it is now atand at the router and run the test, log the download speed. Move half way between the router and your son's room, run it again, note changes if any. Final, go into your son's room and run it one last time, note changes. Then disconnect the splitter and reconnect the router only, re-run the tests, note changes. If the speed test shows a difference when split and not split then that maybe it. You can also go to your local Comcast Store and get a new router, coax cables and ethernet, they should provide them free of charge. Ethernet should be CAT5E (written on the cable), Router models differ, but ask for the latest one, I was just able to get a new one from them that works much better. If NONE of that works then Message back and we will work on it! Good luck

You are welcome. While the stats requested by the other user will provide some useful information, simply testing the wifi strength around the house in the 2 different scenarios gives you basically the same result, but without you having to know how to access and read all that stuff.

We know there was no issue until the splitter. So, the WAN must have been fine. The LAN also had to be ok until the splitter was added and if there is a way that adding a splitter can ruin the signal coming in, before it hits the spilt, then that's just a bad design. Therefore it must be the LAN, also he did not mention that the speed was bad, it was the signal, again rules out the WAN. So, the problem is the LAN, then I would want to know, since I do not know the layout of the house, where the signal drops because it maybe interference from something in the house. Most likely it is the splitter since that was the only change.
