I don't think the ISP is the cause, apparently something was changed after the patch otherwise this problem would be occuring before te patch as well.
I can not imagine that a whole lot of ISP's change their setting at the same time tripwire patches RO
I'm on XS4all in the Netherlands so is Monk, but he uses the KPN network and I don't, beast is on planet , also KPN but babbel is in London so that can't be the cause.
What i'm saying is not that an ISP changed its setting, its that ro changed the master server and reporting method. Meaning different ports, and route paths for your internet provider, and a different way of sending data.
Now i might be totally wrong but 3 guys with the same isps is too much of a coincidence for me, especially since monk tried a cable connection too and it worked ok with that. Then when connecting through favorites works.
That implies to like it does with you that there is an issue with the master server, and from what i see most likely by the isp or possibly the modem since people at the same isp usually have the same modem etc.
There are 5 people with this issue on these forums now, meaning in total there are probably like 25 total players with an issue like this. This is an incredible small amount. So it must be caused by something a few people have in common, and so far most likely its the ISP or hardware supplied by the isp. Which is why i made that info thread to get information on what things people have in common.
I'm not saying there is no bug, but the bug only seems to happen when there is something going on with the master server connection. And at least contacting them about this issue and stating in the other thread all programs/hardware that is network related will give a better insight on the issue.
To fix an issue the source must be found, everything is always triggered by something and can be explained in the computer world.
