ARRRRGGHHH HELP, I'M HAVING A 'MARE!

35 replies
Found 17th Dec 2009
Firstly sorry for the generic 'can't connect to the internet' post.

I'm currently sat on my dads laptop, which is connected to the wireless network fine. However, mine will not.

It finds the router ok, and even says that is connected to the internet (the symbol in the tray bottom left shows 2 screens and a world) but i'm getting Internet Explorer cannot be displayed.

When I run the diagnostic, it is saying 'Cannot communicate with microsoft.com - network diagnostics pinged the remote host but did not recieve a response'.

It gives me the option to resent the Wireless Network Adaptor, but i've tried this and it doesn't help.

I've also completely shut down and rebooted my laptop and the router several times.

I'm running Windows Vista and my laptop is a HP Pavillion dv5.

I'm fresh out of ideas and i've got essays to write...

If someone is feeling benevolent and could offer some help or advice, i would be eternally grateful.

Many thanks

Are both machines using the same IP address? (This will result in one connecting but not the other.)

Can you try connecting your laptop to the router using an ethernet cable? If so, does it work?

Will keep thinking...

You may have a corrupted winsock

This may help.

Scan your PC for malware afterwards, every which way you can.

Have you tried the help pages here?

You can also chat with an HP adviser on the above link
(I have used them before & they are really helpful)

I've just popped an ethernet cable in but it hasn't worked.

I don't think they are using the same IP address, because we have had them both up and running on the same network for months.

thanks

So what IP address does it have (the faulty laptop)

Had the same problem recently in that my laptop had lost its ip address had to get someone out to it, don't know what he did but it only took him 5 minutes not much help I know. Can recommend the nationwide firm I used they charge £35 for call out and first 30 mins then £7 per 30 minutes after

Are you 'not connecting' or is it that the browser isn't accessing the internet.

I just ask because the latter could be a firewall issue. You may need to allow IE as a trusted program or whatever the process is on your firewall. Simple test would be to disable the firewall and then try reopening IE.

Original Poster

The ip address of the broken laptop is 192.168.1.68

the healthy one is 192.168.1.70

the browser doesn't seem to be accessing the internet i don't think, i've got AVG - should i fiddle with that?

i'd turn off all firewall software while you try and fix the problem (AVG is anti-virus though, not firewall).

Have you renewed your IP address? ipconfig /release and then ipconfig /renew, to ensure DHCP is working.

Original Poster

I just tried ipconfig/release but it says 'the requested operation requires elevation'

bad news?

no, you just need to open the command prompt as an administrator.
Go to All Programs, Accessories, right click Command Prompt and click Run as administrator.

Then try the commands again

Firewall is usually something like Norton, Windows own or ZoneAlarm.

It could be that you either have a firewall that is blocking IE or that you have both a third party firewall and you have left the windows one on as well and they are conflicting.

Original Poster

ok, done and done. What should i be looking for?

Thanks for your patience by the way...

can you ping anything?
try ping 4.2.2.1 and see what the response is.

It used to be half the time the Anti Virus software was responsible - no soooo much nowadays though. You can always try uninstalling it and reinstalling when you do get connected. It's not doing much for you anyway if you're not on the 'net!

I think it's more likely the modem/router though. Reboot it, and the PCs. CTRL+ALT+DEL has solved more computer problems than any helpline!

*Sorry just realised you've said you've rebooted in the op - I'll get me coat...

I had windows firewall on, tried turning it off but it didn't help.

just pinged 4.2.2.1

the response was packets sent:4 recieved: 4 lost: 0 average round trip: 23ms

is that the data you were asking for?

yeah that's what i was after, just to prove that you have no internet connectivity.
can you ping the router? prob 192.168.1.254? do ipconfig /all to check, and look for default gateway.

Original Poster

just done.

results sent:4 recieved:4 lost: 0 trip: 24ms

hmmn, wierd.
The working laptop, is that XP or Vista?

Original Poster

Vista. Its a pavillion dv7.

I'm bemused because when i open network and sharing centre, it says connected to o2 wireless router and the to the internet as well. Signal stregnth is excellent, and when i look at the connection status it tells me ipv4 connectivity: Internet .

You could download firefox or chrome on another computer and transfer over the exe file and install it on the problem laptop to see if IE is the problem.

have you tried manually set the ip and the default gateway for your wireless network? I had similar problems when I'm working at my dad's off his router. My wireless network is configured auto setting for ip, but as soon as I manually enter the IP and default gateway, it works for me. Give that a go.

Sorry for my ignorance, where should i look for the information (ip and default gateway for my router) and how do i manually enter?

Again, thank you for your patience...

If you don't mind, send me your email address via PM, I'll send some pictures and instructions over.

How does trying to ping 4.2.2.1 prove that there is no internet connectivity? Did you try it on your own machine?
My machine has perfectly good connection, but 4.2.2.1 still returns Request Timed Out, so possibly an unused address.
A better address I would have thought would have been 74.125.79.147, which is one of Google.com many IP's.

If both PCs are set to DHCP, and both have received Ip addresses, but Dad's connects and yours doesn't then it's got to be either your PC or the router.

It's 'possible' that the router has been configured to only allow internet access from your dad's PC, but unless either of you have fiddled with the settings on it, that would be unusual.

If you open Internet Explorer and go to Tools --> Internet Options, then the | Connections | tab, what do you have set under the "Choose settings if you need to configure a proxy server for a connection" ?
If you only ever use wireless or cabled ethernet then it should be set to 'Never Dial a Connection'.
On that same tab click the [Lan Settings] button what do you have?
Ideally you don't want 'tick' marks in any of the boxes, (if you previously used the laptop at school / uni etc it's possible it is looking for a proxy that is no longer available).

Good luck

if you're not getting a reply from 4.2.2.1 then I suggest you might want to look at your own setup, as that IP address is a well known easy IP to remember for those of us that work in this field. :thumbsup: Unless of course you find 74.125.79.147 easier to remember.

Original Poster

I do indeed have 'never dial a connection'.

under LAN settings i have a tick in the 'automatically detect settings'

However, i've always used Wireless, both at home and at Uni.

Can I ask what 4.2.2.1 is? I meant no offence by it, was just stating that i can't contact it from my 'connected to the internet' PC either. using an online website to remotely ping that Ip address I can see that it does respond, but from my work PC I still get no response. Intrigued now as to what that IP address relates to


As for the OP's problem, if Winsock is ok, and the I-net settings are ok, and the wireless settings are ok, (and changing to cabled makes no difference), then it seems to me to be pointing more and more at the Router?

Ah, the key bit of neglected information - lol
Was it working fine yesterday AT THE SAME TIME as your Dad's one, or have you only ever had one or the other connecting to the internet?

Haven't got a clue what it is, but I've been using it for years now, it's a great little address and I will be annoyed if/when it ever disappears.

have you added the IP details manually as suggested earlier on in the thread?
You'll need to do ipconfig /all and get IP address, default gateway, subnet mask and dns server(s), and put them into your network configuaration instead of the DHCP option. Also, try using a brand new (unused) ip address, eg 192.168.1.123.

AH HA!

I've never been happier to see google!

Thank you for all your help, very kind indeed. Rep has been added to everyone.

Make sure you turn your firewall back on.
