Range and reliability issues with PACE 5368AC -- Is there are better router/gateway?
I just switched from Cox cable internet to AT&T fiber internet 50 with a PACE 5368ac gateway, and I am having a lot of issues. Internet drops out multiple times daily, and even though the router is located in the exact same place as my old Cox router (Netgear DN6300, which they no longer offer), the range is far more restricted. I'm talking 40 feet tops, but even outside of 20 feet I'm getting maybe 1-2 bars on phones and tablets. Also, when the internet is cooperating, I'm getting speeds consistent with my plan (60 download, 50 upload), but when it's not, and that's just as common, it's more like 20/10 at best. We are not gaming or anything like that -- just standard internet use and only a few devices. Does anyone have any thoughts on how to improve my range and/or reliability? Does AT&T offer a more reliable/higher performing gateway that I could swap this one out for? The representative I spoke to last week said this is a newer router and shouldn't give me any problems, but if it's not the router then what is it? I'm also not against range extenders or getting a better router, although DMZ+ doesn't sound like a particularly desirable solution either, but I can't imagine that I would need both (and spend all of that money!) to fix problems that I never experienced with my old, outdated router and subpar internet service. Any advice would be greatly appreciated! I'm really starting to regret switching at this point...
