DNS issue on T-Mobile ISP
I switched to T-Mobile ISP a week back and only reason for that was couple of pretty good offers. From the time I switched I honestly was regretting as I was facing DNS issues with a few websites and sometimes my work VPN too. It will not be able to reach a few websites for a few minutes and then it would just work like nothing happened. Initially I could not understand what can cause this but then it occurred to me that it must be DNS issue. To my horror, I realized that DNS (and in fact even many basic settings) can not be configured on this T-Mobile gateway. I was facing this issue on a macbook, everything else just worked fine so I then thought of seeing what my macbook was using. It showed local network configured as DNS server, I removed that and added cloudflare's DNS1.1.1.1. That has fixed my problem. In short: If you are facing trouble in reaching some websites periodically and this is happening only on a few devicesthen try switching DNS on your device to 1.1.1.1 or some other open DNS servers.
Home Internet Gaming Connection Issue
I've had t mobile home internet for about a week and the download speeds are actually amazing. and streaming tv doesnt skip a beat, I have no complaints on that end. I'm impressed to say the least. but the whole purpose of buying this gaming computer and getting internet was to game online. Anytime I try play gta v online, fortnite, red dead online, pretty much any online game, I connect to a server for about 10 seconds - a minute and I get a timeout connection failed message. I noticed on all games it says my NAT type is strict which I know isnt good for online gaming. I accessed the t mobile router settings to see if I could change the NAT settings or forward some ports but there is literally no options to change the settings. Before I cancel my service this is my last option to ask the t mobile technical support if there is a fix or work around. thanks
