BT Business hub keeps rebooting

[dholt]

Hi there, 

I am having problems with my bt business hub router. It is the 2wire one, and it is often rebooting when i dont want it too. e.g I open Hotmail in firefox, then it suddenly clicks and the lights on it go off, except for the power light which blinks green. After a while it clicks again and then dials up to broadband, turns wifi/lan on etc. Then I can use it again, until it crashes again. I have noticed that it reboots mostly in firefox when i open hotmail in firefox, but curiously it doesnt do it when I do the same action in internet explorer. Although, recently, however, it has been restarting in other situations as well, eg i opened a website (not hotmail) on my netbook using google chrome and it restarted again. Or I was accessing shared files over my network > restarted. It is getting very annoying for the whole family, especialyy during bookings/card transactions. I have looked through the logfiles but cant find anything different. I will post it anyway, just to be sure:

After that comes when i came to the house, and changed the SSID, It hadnt rebooted before that, of what I know. Since, it has rebooted countless times, up to 10 times a day!

What I posted just there at the top was the EVENT LOG, so this is the SYSTEM LOG:

Once again, the log is only until i chaned the ssid. 

Hoping for help,

Hi Dholt,

Changing the SSID shouldn't really make a difference, could be a faulty power supply or hub itself, is it a 2700 or a 2701?  Shouldn't make much of a difference either way I guess.

Do you get any power cuts or power surges?  This would cause the router to reboot, if not its more than likely faulty, call the tech desk on 0845 600 7020 they'll check a few things and probably get another power supply or router to you.

Thanks,

Steve

Did you tried changeing the wireless channel ? Go with 3/7/9/11 channel and see if it made any difference

The 2-wire hubs are well known for overheating and getting a little slow and cranky as a result (when the electronics start to cook the speed at which the router can process commands drops and this can cause problems), we ended up putting ours on £10 laptop cooler. Not an ideal solution but it worked for us.

The Chrome web browser when launched also submits a flurry of  DNS prefetch requests and is known to upset any router running a tad slow.

Something else that will cause a router to run slower is Firewall activity where the hub stops somebody from accessing your network externally. It will show up in the logs something like this...

Unknown inbound session stopped  and there will be an IP address (probably originating in China)

Do Not Panic, this sort of thing goes on all the time. It's the digital equivelent of a a kid checking the coin slot on payphones looking for loose change. Suffice to say the rarely find anything and it only becomes a problem if they are scanning your ports thoroughly and frequently.

Check the WiFi logs for anything unusual, if you are using WEP encryption I also strongly advise changing over to WPA. This will not stop somebody piggybacking your Wifi completely but does however make the process more complex & time consuming, so they should go away looking for easier targets. Competant hackers are known to reboot the router inorder to cover their tracks.

Last of all run a full virus scan on all machines, better still use a Linux boot disc and scan because if you have inadvertantly installed a virus with another piece of software or toolbar regular AV will probably not find it.

I have never had an overheating problem on the many 2wire devices I used or have access to.    They are all mounted vertically which allows a good airflow.   Some are wall mounted.
