Even on the 'good' modem I occasionally get drops in the RU connection (ie. I get signed out and also lose remote connection). On the good modem this doesn't affect anything else; I don't lose the ability to navigate.
What I am currently thinking is something like this: perhaps my internet is not very stable. Let's say I get microbreaks in the signal. For some reason, this computer deals with them OK when connected via some modems, and with others it gets confused/blocked somehow.
I have tried the flushdns command before (as well as release, renew etc). I tried it again just now (just in case !), and still no luck. The problem persists.
The Chrome error I get is "This site can't be reached. The connection was reset."
Good question - yes, the problem occurs with Viewer open, even without actually being connected to another machine. I *think* that it happened once without RU being open at all. I don't think that RU is the cause of the problem here, BUT it increases the frequency of the problem from days to minutes!
I have been using RU Viewer for a couple of years on my old laptop without issue. I recently bought a new Dell laptop with Windows 10.
When running RU Viewer, I regularly get a complete loss of internet on my machine. I cannot access the internet from ANY program/app (browsers, RU Viewer etc). I am still connected to the WiFi, but it's as if there is no connection to the outside world. The timing varies, but on average RU will work perfectly for about 10 mins before the whole thing cuts out!
I CAN still ping - both the modem and external websites.
This issue is only present over WiFi. If plugging in via an Ethernet cable, there is no problem.
To make matters even more confusing this problem only happens with certain modems. My neighbour's modem works perfectly at my house, yet my own TWO modems both show the same problem (one brand new, the other old).
In all cases, I can run my old Win7 laptop right next to the new one, connected to a remote computer, and never experience this problem; it's definitely something specific to this new computer. As I said above, it works perfectly for a little while (up to an hour sometimes, but usually much less) but then it suddenly cuts out.
I've tried reinstalling the WiFi Adapter driver. I've tried various settings in Windows. I even tried reinstalling Windows. Nothing has fixed the issue. The problem is the same with or without AV/firewall activated.
I am suspecting some sort of configuration problem within Windows, but I'm open to any suggestions at all.
I am going nuts here!! Any suggestions very welcome.
