I wonder if someone can help. I have a BT broadband account and use a BT Home Hub Version 2 (type A). Recently I have had problems accessing the routers homepage (220.127.116.11) from my devices. Basically I have 2 laptops, an iPod touch & an iPhone 4. Now all the devices can all happily access the hub's homepage but as soon as I turn my main laptop on all the devices suddenly start returning an 'access error: 503 - service unavailable' message. I don't lose any internet connectivity, the problem just surrounds trying to access the hub's page. Oddly the main laptop doesn't get affected though and can still access the router homepage fine. Then I will turn the main laptop off and after a few minutes all the other devices (other laptop, iPod touch & iPhone 4) will now be absolutely fine and are able to access the hub homepage. This problem doesn't always happen but I'd say 75% of the time when the main laptop is switched on it occurs.
I don't think this used to be an issue and the only thing I can think of changing is my main laptop. It has McAfee Security Centre on it. Recently there was quite a few major updates on the McAfee suite downloading. The whole look of it changed and even the system tray icon changed (changed to an M inside a shield as opposed to an 'M' inside a square box). I believe the problem co-incided with this update. Does anyone know of this problem? I think McAfee is prompting this problem. I tried the McAfee forum without joy. Also I introduced the iPhone 4 to my home network recently so maybe that has triggered something. Although switching the iPhone 4 off doesn't suddenly allow the other devices to access the homepage.
Thinks I have already tried without success:-
1- Replacing BT Home Hub with a different one
2- Switching on UDP tracking on McAfee firewall settings
3- Turning the McAfee firewall off for a short period
4- Connecting main laptop via ethernet instead of wireless
5- Running several spyware scans (spybot, mcafee etc) to ensure spyware is not flooding router
6- Eliminating iPhone 4 from network
7- Ensuring hub security is WEP
Something on the main laptop is triggering the issue. None of the other devices lose internet but they just can't get into the Home Hub page 18.104.22.168. Even when the main laptop is switched off it then takes a good 10 minutes for the other devices to be able to get in. Very odd. I do find it surprising that a single laptop being on can affect all the other devices. Some kind of service starts running though that causes some kind of block.
Thanks in advance,
