Wireless Optik Box and PVR issues after multiple replacements

Hi

What is 3rd party networking gear? I don't have any boosters, and not sure if there is something wrong with my account and streaming as it happens on and off.  Even the other day my PVR lost a bunch of recordings and not sure why?

I've been in touch the last month or two with an escalation manager, testing different ways to use the wireless optik box and it still does the same thing intermittently.  He sent a new box a few weeks back to try and it still has the same issue.  It's very frustrating as even today I had a show paused for maybe 10 min and it jumped to live and wouldn't let me rewind so I missed the show completely.  It's been going on for a long time now and annoying.  I have had a few boxes, and even a technician who came out months ago and checked the speed and blue light and adjusted it so it should be running better, but still issues.  I believe I have the 250 plus internet speed, and it only seems to be happening on one box, not the other wireless optik box which is located in a different room. 

I have called tech support a few times and they reset it or say they can't see issues, but it's very frustrating to pause something for maybe maximum 30 min and it jumps to live, or says I have too many tvs being watched when nothing is recorded/no other tv is on... I have only been having constant issues since I upgraded to the optik line last fall between my pvr not working properly and moving it, to now the wireless optik box also having issues. 

I've even unplugged the blue tooth wireless subwoofer to stop any interfering frequency and it hasn't fixed the issue.
