Switched to Orange today and broadband virtually unusable

Switched to Orange today and broadband virtually unusable

Hi all

My broadband switched over from O2 to Orange today and I connected the BrightBox at about 3pm. Since then the connection has been dropping very frequently (say once per minute or two) and consequently it's impossible to use VPN / Remote Desktop to connect to my work servers. Not to mention impossible to stream BBC iPlayer etc or online gaming (my son, not me, honest!). I'm frequently having to refresh pages to get them to load.

I spoke to Orange and they said this was normal during the 10 day line stabilisation phase, however I don't recall it ever being as bad as this when I switched to O2 a few years ago.

I've looked at the log on the advanced settings page of the BrightBox router and there's nothing to indicate that it's dropping or re-syncing.

However there were entries warning about a possible DoS attack from the laptop I was connecting from! This related to a time when I repeatedly tried to log on to 192.168.1.1 but it kept on just returning either a blank page or else Chrome saying "Google Chrome's connection attempt to 192.168.1.1 was rejected". Odd...

With O2 the max speed we were getting was 14Mbps, but typically 7-10Mbps was more common, and the connection was very reliable.

I should add that it's not the wireless that's dropping as I've disabled the wireless on the BrightBox as I use an Apple Airport Extreme as the wireless access point.

So my questions are:
a) is this normal?
b) will it improve over the next 10 days?

Thanks very much

a) No
b) Probably not

Can you get the stats for the line from the router, the fact the PC is having trouble with going to the router suggests something is wrong.

Do an ipconfig /flushdns to clear the DNS cache, also unplug the Airport just to make sure its not an issue

Hi Andrew, thanks for replying.

I've run ipconfig /flushdns and have also connected via ethernet cable straight to the box and am still getting these problems. And what's more I can't connect to 192.168.1.1:

"Google Chrome's connection attempt to 192.168.1.1 was rejected. The website may be down or your network may not be properly configured." I've also tried to get to it from my iPhone but I get a similar message in Safari.

However I'll keep trying and will post the line stats when I get through.

Thanks

Tim

How sure are you that the router is at that IP address?

What is the gateway address listed when you do an ipconfig /all

I get logs of DoS attacks from my Vista laptop every time I switch it on. It is quite normal but nothing to do with trying to access the router's GUI (192.168.1.1 is the usual IP of the BrightBox).

If it keeps disconnecting there must be log entries like:
Tue Oct 2 12:21:03 2012 PPP connection up (VC1)
Tue Oct 2 12:21:02 2012 PPP: IPCP up

Very nice connection

Upstream 1279 (Kbps.)
Downstream 18851 (Kbps.)
Noise Margin 6.9 dB 5.1 dB
Line Attenuation 11.8 dB 20.0 dB

Margins are fine and logs show it is not dropping out. So now to figure out why the other machine does not like the router.

Some firewalls complain about possible DOS attacks when something odd is going on with DNS. What are the DNS settings on the machine that is not performing very well, and what firewall / AV suite is it running.

[re: MrSaffron] [link to this post]
 
Thanks...!

I've restarted the Airport Extreme and the Windows 7 laptop and things seem to be better on other devices apart from the Windows laptop (connected by wifi or ethernet).

Outlook won't connect, nor will iTunes Match, Skype or Spotify... Meanwhile my iPhone is streaming iTunes Match music fine... And my iBook can refresh web pages when my windows laptop won't...

The DNS settings on the Windows laptop are supplied by the router (or the Airport Express ?)

Thanks again

Ok, I think I've found the problem! The Airport Express was using manual DHCP and had the same IP address as the BrightBox! Doh...

IIRC the O2 box was 192.168.1.254.

Fingers crossed, and thanks for everyone's help.
