I ran a coax cable from my house approx 200' out to my workshop where I connected a TV and STB and that works fine. However I tried connecting an Actiontec WCB3000N network extender (purchased from Verizon, it's the correct version) so that I could have a wifi signal out there also and that seems to have two issues:
1. The green coax light is flashing (I'm assuming it doesn't have a strong enough signal?) and my router shows the extender as inactive.
2. For some reason this seems to cause a disturbance in TV data network availability which primarily affects on demand programming, but also slows down the channel guide. When I disconnect the extender then everything works fine.
The WCB3000N works fine when it's in the house and there are no TV issues then. I've checked and remade the coax connections so the only thing I'm left with is assuming that the cable run is too long at ~200ft.
Anyone enlighten me?
