OK so i have 3 TVs with a swm setup with one line coming from dish going to a 4 way splitter. I have an hr24 hr21 and an h21. I also have MRV. The hr24 has the deca built in. The other 2 have the deca modules on the back of them. I have my router next to the hr24 but when i hook it up to my router i get internet but lose MRV. I've searched and read that it does that and i need something to fix it but what exactly do i need to get my MRV and internet access working??
