IP address problems


[link to this post]
 
My mum is with Sky and has the Netgear DG834GT router from Sky.

Recently, when she switches on her computer, she's getting two messages:

IP address is not recognised

and

IP address conflicting with other network

She's having a nightmare trying to get internet access though she does get it eventually. Strangely, it seems to be at the weekend the problem is worse because when she switched on this morning, there was no problem

Does anyone know what could be wrong? She's convinced that somebody else is using her broadband connection.

I've tried searching for the error messages and best I've come up with is to remove Sky's firmware from the router - but would that cause problems with Sky?

I'd be grateful for any advice.

Has she got the PC to Obtain IP auto?

And router has DHCP Server ON, with assigning IPs in the 192.168.X.Y range?

Make sure the Wireless is OFF, if she doesn't need it, or, if she does, it's set to WPA2 with a difficult key.

Yes, PC is set to obtain IP automatically and DHCP server is on.

Wireless is on and it's set to WPA2 with the key that sky assigned.

It's only recently that this problem has popped up - and nothing in the household has changed.

That's correct!

Think this can happen when it can't connect to Net, only Local.

When this happens again do a 'IPCONFIG' in a DOS Window (assuming it's a Window PC) and post results.

Also look in Network Connections for an Internet Gateway.

Think I had similar occasional trouble when I 1st used my DG834GT. It was caused by that router having UPnP ON and that causing an Internet Gateway to appear haphazardly on my XP PC. Try switching UPnP OFF in router.

EDIT: Is she connecting wirelessly? I only had problem on my wireless PC.

I'll need to check. The laptop connects wirelessly but I'm not sure how often that's used.

My brother also has his Xbox going but not sure if that's wired or not, plus iPhone and goodness knows what else (it's amazing what you get told is also needing internet access after you've asked a question!!)

It's weird that it's just started happening. I have to say though, the internet connection has always been deathly slow and unreliable but these new problems have just popped up.

And apparently, every now and again, she's getting the message that there is limited or no connectivity.

I get this occasionally as we have 2 ipods and 2 playstations connecting wireless, and 2 PC connecting wired.

When you get it:

Start, Run, type cmd.exe press <return>
Type ipconfig /release <return>
Then type ipconfig /renew <return>

This will force it to release the IP address and get another one.

When you get the limited or no connectivity message, right click on the network symbol and select Repair.

Which of all the devices does this occur?

What O/S is her main desktop?
