Hi all.

Having read some of the posts here, I have been impressed with this forum. I wonder if such expertise could help my problem.

Two dells hardwired to a router on BT BB. PC One has no issues other than getting no cnxn which is normally solved by rebooting the router. The other has just suddenly refused to connect. I have changed the CAT cable, tried no firewall, and can ping ok. IPconfig shows no surprises.

Assuming its a machine thing as the other pc can connect, use browser, get email etc. The fact the the pc with issues can ping ok is a surprise, and the IPconfig looked ok. {Although not an expert here}

I should say its my 15 year old son's pc on a network with his mums. I live round the corner :-)

More info :on the troubled pc 2, in 'Network Connections' under 'LAN or High Speed Internet' the connection is showing as 'connected'. Also, strangely, an icon comes up on the task bar saying 'the BB cnxn is uplugged'. Well obviously it is connected physically. Have changed the cable with no different result! Since thats been coming up the issues have occurred.

Router is LINKSYS WAG54G ADSL Gateway, hardwired not wireless.


Any help is really appreciated. I will post a trace as soon as I return to my son's tomorrow. Is it worth just trying IP release and renew? Pushimg my knowledge here now

Hi CPFC
That is an odd one
Step 1) start internet explorer >tools>internet options>connections tab>lan settings
All the boxes should be unticked.
Step 2) Can you ping apple.com from the broken computer.
If Not
Step 3) renew release ipconfig
if no change do you know how to set a static ip address?
Cheers

Ps have you tried switching ports on the back of the router - could be a dud port.

Cheers for that Peterm.

I can ping bbc.co.uk ok, so I presume that's the same as a pinging apple.com I will try again anyway. There is only one port on the pc, so if that's a dud....I can't check it against another without putting another one on the mobo. [I might just to check]

I will try IP release and renew.

He's trying to say on the back of the router.

If the computers are close enough to each other... just unplug Ethernet cable from one and put it in the other. If the problem switches to the other PC, we know you have an issue with the port (on the router) or the cable. If the problem stays put, it's an issue with the computer (could be hardware or software or configuration).

Welcome to GTG (unless I'm too late in which case welcome back to GTG)

Ahh bobmad, I have already tried that. I have got a new cable to the router from the pc and tried that as well. I do have a spare ethernet card, so I will try that as well to check the port on the pc isn't playing silly buggers.

I'm gonna go with the the IP release and renew thing as the next step. Tell me this is a weird one please: it's making me feel a bit silly.

[bobmad]

This is a weird one. I did tech support for an ISP. Can ping but no connection is very odd. Most of the "normal" things it could be have been checked.

Ahh bobmad, I have already tried that.

So when you moved the computer end of the cable from 1 PC to the other the problem stayed with the PC right? That eliminates some possible causes.

After you've done the release renew, putting in new Ethernet card may be best step. You may want to add it (if you have room) rather than replace the other card. Please use a static IP address (because the DHCP one is the broken one) to make troubleshooting easier.

[peterm]

did you try the static b4 replacing the network card

[CPFC]

Hi bobmad.

Yes, when the cable was swapped, the problem stayed with the troubled pc. Thats mainly why I think it is machine specific as opposed to the router etc.

Hi peterm :

I will try to set the connection up again with static before I pop on a new ethernet card. I should be ok with that, I'll open the thread with instructions as a precaution. At least I get to stretch my knowledge a bit more. IP release and renew did not seem to work.

At least I feel better about this, I was getting concerned thinking I might be being really stupid lol.

Thanks both for your time and effort so far.

You are not stupid. You did much of the troubleshooting correctly before you posted.

You've just got an odd problem on your hands.

[CPFC]

Cheers for that bobmad ! I've cut and pasted the first sentence to all my friends :-)

I will return to my sons on Saturday and have another bash. I'll post the results back up. Again, cheers for the help so far.

Oddly enough I am just enrolling for a CISCO networking course. I keep telling myself I have to get used to this lol.
