There was a guy in the Just-Dice chat who was getting disconnected every minute or two, and then couldn't reconnect for a few minutes.
I couldn't figure out what was going on, so I asked him if I could use teamviewer.com to take a look around his computer.
It turned out that his ISP's DNS wasn't able to resolve just-dice.com at all. And yet he was able to visit the site in IE, Chrome, and on his phone using the wireless router.
I can't understand how he was able to get to the site at all given that his DNS couldn't look the site up. Can you?
Anyway, I set his wireless connection up to use google's DNS service at 8.8.8.8 and he's had no trouble since.
I would recommend doing the same to anyone who is having trouble connecting.
Here are the steps I took on this guy's Windows 7 machine to set up the google DNS:
1. right-click on the network icon in bottom right - the only that shows your wireless connection strength
2. open network and sharing center
3. click on 'wireless network connection' towards the top right
4. click 'properties' in bottom left
5. click 'internet protocol version 4'
6. click 'properties'
7. to switch to google's DNS 'use the following DNS server'
to switch back, put it back to 'obtain DNS server address automatically'
8. I put 8.8.8.8 into the preferred DNS box. to change it back you don't have to put anything there
9. click OK
That fixed the problem for him, and should do for you too... Good luck!
Edit: I've had a report that using 8.8.8.8 in step 8 didn't work, but replacing it with 4.2.2.4 did. I've also had reports that 8.8.8.8 works fine. They're both well known legit DNS servers.
