I'm going to detail how my system is set up because I think it's important, plus I live in an apartment building, which makes it slightly more confusing.
We have one Directv dish on our roof. From the dish is a coax cable that goes into a router of some sort on the side of our building. A cable from that goes around the building outside into my apartment into a kind of splitter, one goes into my HR24 receiver, the other goes into a DECA Broadband Adapater. From the DECA Broadband Adapter is an ethernet cable that goes into my router and that's it.
I've been having network problems lately, which are long to describe so if you want the short question here it is: Can't I just have my directv coax go directly to the directv receiver and then have an ethernet cord go from same receiver to router?
For more information on my problems, here you go:
Recently noticed my internet was going slow so I went to speedtest.net to see if my perception was correct and I'm getting a fraction of the speeds I was before. When my speeds are a fraction I also tried to connect to my router through 192.168.1.1, like I always have, and it didn't work. I opened a command prompt and it said my default gateway was 192.168.254.254. So I went to that. Entered a generic username and password and got into it. The page was a Frontier page. Frontier is a different ISP in town, not mine. The page also seemed to call my router a modem. Reset my router, modem, all of it. Even bought a new router and the problem persisted, but only sometimes. Sometimes I would turn on my computer with a wired connection it would be normal, then would seem to change randomly at certain points.. Even my Xbox and wireless devices were using the 192.168.254.* ip configuration.
It wasn't until today that I started unplugging ethernet cables from my router and going into "connected devices" on my router's setting page that I noticed the cable that goes into my router from the DECA Broadband device has the IP of 192.168.254.254, So I'm pretty sure that's my problem. The DECA Broadband Adapter... Don't know why this just started after 2 years of Directv service. Anyways, I think I've isolated the problem, now my question is how do I fix it?
