on 2nd 2701 HGV-C still freezing up

[kevinneal]

I have just recieved a replacement BT Fibre Router and it is freezing intermittently exactly like our original one.

Basically what happens is all computers are unable to access websites for a few minutes (wired and wireless) then it continues working without any interation, the problem is it is dropping about 20 -30 times a day.

BT have done line tests and the line seems to be ok. Which is why we were sent a replacement router. When the websites are unreachable, the router admin is also unreachable. This has happened on a Network Connection, Wireless connection and direct wired connection.

I left a ping running to the router IP address while my laptop was directly connected to the router and still there were ping timeouts for a few minutes. While this happens the Internet light freezes on solid green, but there are no red lights. the router then just starts working again without power cycling and the router is not hot to the touch.

The fact that a direct connection ping timesout surely points to a router hardwear problem, but its very strange that we have exactly the same issue on both routers.

I have just done a full reset of the newest router and the only settings I changed from default were, username and password and the router IP address for 192.168.1.254 to 192.168.181.254 and turned off DHCP because our Xserve is providing DHCP for the network, and it has just frozen again!

I am running out of ideas ...

Me too, hopefully the third router will be here tomorrow, if that still not working my only options would be to get a third party router or to get BT to release us from the contract and go with another supplier.

Try the router "out of the box"  - no firewall, no ports opened,  no wirelss security &c, and just your PC connected.

If it is all clear then start the re-config,  part by part checking as you go.      If it fails then there could well be a modem/router issue and the modem may be sustpect.

Same here. I have done a lot of ways and have drained my resources, but to no avail. I will just wait for any update to have this all fixed.

Does your server handle the DHCP?

In your ping tests, when the timeouts occur, are they preceeded by large latency spikes?

Thanks

[kevinneal]

Hi was that question to me or the person above you? If me, then yes our Xserve handles DHCP and it is disabled on the router.

and yes the are latency spikes beffore the drop outs, see the graph for yesterday, ignore the solid red block for an hour in the afternoon - that was a test with the modem disconnected.

and again at around 5am today there is the first spike/drop out, thats happened 3 work days in a row yet no one is in the office at that time and I can't think of any automated tasks that would happen then

There have been some weird and wonderful issues with the new firmware that ends in 63.  If you have another router to try and it works then I would go with that.

[kevinneal]

Plugged in 3rd router 45 minutes ago, and its frozen 3 times, did notice the firmware on this one is 6.3.9.41-plus.tm

It didn't freeze while I was the only one plugged in, but that could just be due to the intermittent nature of the problem, but even while I was direct connected with no other cables plugged in the latency was awful and the various speed tests showed 14Mb/s

I am going to try turning DHCP off on the server and on on the router just to see if this is the problem

[kevinneal]

wow just had my shortest phone call from BT support ever, basically she rang and said they will pass it on to their fault team and get an engineer to call us and probably visit.

We have also bought a DrayTec Router as something else to try

Update:

Has a BT engineer on site all afternoon, he did discover that the original engineer who installed the Infinity face plate had wired it up incorrectly (there was an alarm connected to the line that was wired to both the digital and analog line unfiltered) so he fixed that and our sync speed and throughput speeds have increase significantly. HOWEVER the original router freezing issue was still there! He witnessed it happen and it completely stumped him, In the end he gave us our 4th BT Business Router and so far it hasn't cut out, though tomorrow will be the real test, The serial number on this on starts 38 there as all the previous ones were 48, maybe a dodgy batch!
