I just want to note that both of our issues could be completely different and have no resemblance to eachother, but I figure it sounds similar to me so I thought i’d tell you my experience.
We experienced this for several weeks on and off, our internet would randomly cut off (but the router would still be transmitting empty signal), and we’d have no connection to the internet. After about 5 minutes, the internet would reconnect for everyone in the house, and go off again soon after.
We called our ISP (Telus, a canadian network), and they sent a technician. He diagnosed the problem and could only tell me what was causing the internet to go down, not what was causing the problem. Since our computers are considered foreign hardware he basically said “The moment I try to diagnose what it is on your end, is when I start charging $100 an hour for my time”.
My computer, and the other gaming resident of my house are set up with our computers in the attic, which connect to a splitter in the middle room, which connects to the router on the stairs directly below us. 2 connections go into the splitter, which then send 1 whole connection to the base router. The technician said the error was only happening when both of our computers were connected with a solid line to the splitters simultanously, and as soon as one of us were unplugged it would stop.
He said that something one of our computers was doing was sending data or whatever through the splitter, and something in that data was causing the splitter to throw a constant group of errors, and once the errors reached critical mass, the splitter cut the connection so it could clear the errors. He saw these errors through the ISP’s software, so we never got to see what they were.
I personally first started seeing this happen when i used Gameranger to play Star Wars Empire at War with other people, it soon got to the point where if gameranger was connected to the network, it would shut off almost instantly. We later started using Tunngle, which made the occurence less common or instant, but it still happened. I have since been using Evolve, which has provided me with the least issues in all cases. This is really the only thing I can even imagine could be causing the issue.
And still, I don’t know, I have no way to diagnose what ever caused it, so I pretty much have no way of stopping it from happening. The Technician suggested it could be a virus (suggested this because the problem stopped for a series of weeks and started up again afterwards, showing the anti-virus’s inability to keep up with its evolution.)
I don’t know, you characterize your situation as being caused by ROBLOX, so that suggests to me it might be nothing like my problem. But do with this information what you will, it sure has given me a hell of a time. For all I know, ROBLOX could be causing it.
*Also note i’ve said splliter alot, to avoid confusion I would characterize it more as a hub that emits a seperate wifi signal that all of our computers plug into directly.
