Your welcome tomturneruk
I’m glad it is all working again and the solution might also help others if they get a similar problem too 🙂July 25, 2009 at 5:04 pm #196863dockehr
Memberjeepers01, once again you came through with an excellent post on solving a problem. The real clincher were the “illustrated” posts. A well-deserved Thanks.
tomturneruk, to satisfy my curiosity, did you encounter connection problems right from the start, or had you changed settings and then the problem occurred?

Participantdockehr – Thanks for your kind words 🙂
tomturneruk – To fix IP addresses (to make them static) see example below
Choose an IP address below the router DHCP starting address. ie in this case tell the DHCP server to start issuing addresses above 192.168.0.21. Also making sure that other devices on the network use different addresses. The Default Gateway is your router IP address
I use fixed DNS Server addresses from http://www.OpenDNS.org because they are very fast
If you choose to use them it is best to change them in the router as well to get the full advantage of the surfing speed increase I have found I get over my ISP’s rather slow DNS servers. It really does make a difference to the surfing experience, for me.
I get between 20 and 30ms pings whereas from other ISP’s the pings can be up to twice as long.Hope this helps

MemberIt is all from an internet connection I used in a hotel. It seemed to get into my computer and change everything – IP and even workgroup name.

MemberI’ve got as far as trying Start>Run>ipconfig /all
My netbook doesn’t give any information at this point
All I get displayed are the words:
Windows IP Configuration
(I’ve checked on one of our laptops that I’m typing the cmd correctly and it’s working on the laptop.).
Does this mean something is seriously amiss – any suggestions for what to do next?
Many thanks,
SAPAugust 22, 2009 at 5:57 pm #196873jeepers01
ParticipantTry Start > All Programs > Accessories > Command Prompt
Then ipconfig /all
It may be something as simple as scrolling the dos box window to see the details after Window IP Configuration ?Else do you have a working network, wired or wireless at the moment?

Why so complicated? Just press Windows key + R and typeCode:cmd /k ipconfig /allBut as sap1 wrote he did this and only got the line “Windows IP Configuration” which is quite strange, almost as if the networking stack is not installed.
I’d recommend checking for malware with Spybot Search & Destroy and an anti-virus program.
If this and one or two reboots yield nothing I’d reinstall Windows XP Servicepack 3 and the subsequent patches. At least this solved a arcane VPN problem for me.August 22, 2009 at 8:29 pm #196874jeepers01

There are always several ways to achieve navigation within XP, so of course there are invariably alternatives. The important thing is to get to the objective.Quote:But as sap1 wrote he did this and only got the line “Windows IP Configuration” which is quite strange, almost as if the networking stack is not installed.That is why I asked sap1 if there is a working network connection at the moment as if there isn’t it will probably point to IP stack corruption or indeed the absence of the entire stack.
Quote:I’d recommend checking for malware with Spybot Search & Destroy and an anti-virus program.Yes it would be a wise move to see if any ‘nasties’ are the cause and perhaps there will be other symptoms that sap1 has not reported here as yet which may confirm this.
With the information supplied so far it is looking to me as though an F4 at boot reinstall will be the most effective way of restoring the system to normal operation. Time will tell 🙂

Even when my system has problems I actually like to get to the bottom of it but I avoid reinstalling Windows. It’s a pain the south to get all my configurations in all my programs right again. 😉August 22, 2009 at 10:26 pm #196875jeepers01

Yep you’r right, it’s the last resort to have to decide on a complete re-install. A complete pain in the wotsit 🙂 🙂I also think you could be correct in your malware suspicions as sap1 posted last Thursday

MemberThanks for your advice so far.
We’re now thinking its something to do with our router. Yesterday two laptaps would connect but my Sammy still refused (sticks at Acquiring Network Address”). Today, without changing anything the sammy and one laptop connect but the other laptop doesn’t – any further suggestions?August 24, 2009 at 7:29 pm #196876jeepers01

*Have you tried re-booting the router (power down/up)?
*Then re-boot each laptop in turn and connect to the wireless network
*Check the router is set up for DHCP ie serving the IP addresses for each device that connects to it.
*If you are using fixed IP addresses that could be your problem. Just make sure they are all different but on the same subnet
*Check if there is later firmware for you router
*Check the wireless channel is not too close to any adjacent router channels, next door’s router for exampleHow did you get on with the suggestions in the previous posts?
Can you report back some detailsAugust 24, 2009 at 8:31 pm #196881sap1
Member-
*Have you tried re-booting the router (power down/up)?
– Yes several times
*Then re-boot each laptop in turn and connect to the wireless network – yep got 3 machnes connected, one that doesn’t (laptop, not sammy)
*Check the router is set up for DHCP ie serving the IP addresses for each device that connects to it. – yes
*If you are using fixed IP addresses that could be your problem. Just make sure they are all different but on the same subnet – not using fixed IP addresses
*Check if there is later firmware for you router – there is, but when try to upload it, it doesn’t seem to take effect. However was working fine till about a week ago
*Check the wireless channel is not too close to any adjacent router channels, next door’s router for example – have tried changing channelsWe now have one laptop that won’t connect to our secure network but will connect to other local unsecure networks. This laptop was connecting fine to our network all day yesterday whilst the sammy would not.
How did you get on with the suggestions in the previous posts? All suggestions have been useful to give us some idea as to what to look for.
Many thanks!!!!

ParticipantSo the sammy has sorted itself out and the laptop is now the problem. Strange.
As you say it does point to the router especially as you are having problems re-flashing it. I assume you are using a cable connection to load the firmware upgrade. What router do you have? there may be a history of similar problems to investigate.
You could try changing the wireless driver in the laptop to see if it improves but not working on a secure network points to either the laptop driver or the router. If it was working yesterday then something has changed to cause this. Have you tried removing the laptop wireless connection and then reconnecting?
How many concurrent connections do you normally have on the router at a time. It may be it is having problems serving 2 or 3 machines at once. I wonder if it will connect, if nothing else is connected to the router at the same time, by wireless and cable on it’s own.
Are you able to test the laptop on another secure network, because that would confirm the router as the culprit 🙂
