Following a Windows reinstall: Cannot access Router

Baldrick

Baldrick

Hi

I wish I had found this XP Forum sooner. I should have guessed there'd be one and hopefully 'Networking' is the best forum heading to submit it under.

My problem: Due to what is best described as a 'clogged up system' I've reinstalled Windows. I've done this before on my trusted XP machine and not had any problems but this time it's got me well beaten! I use this machine mainly for recording and editing music with software unsupported on later versions on Windows.

With XP 'successfully' reinstalled (albeit graphics in low-res) I carefully set the IP Addresses back to what they were and Windows tells I am now connected to my 3Com USB Wireless Adapter and my signal strength is excellent. Despite this, I can not ping my router (198.162.1.254). All other household devices (wireless and cabled) are still working.

As suggested elsewhere I've unchecked the "Enable IEEE 802.1x authentication for this network" box. This was following an initial error message after reinstall of "unable to find a certificate to log you on to the network". (Unchecking this box turned out to be the only way I could get "Status: Connected/Signal Strength: Excellent".)

I have tried disabling the wireless connection and connected PC to Router using a cable (proven to work on another device) but still can not access my Plusnet Router (the one shown on the left, if it's of any use).

I have also reinstalled 3Com and allowed the default wireless settings but can not get any connection to the wireless adapter.

I am on the latest 3Com Driver for XP (May 2006).

My connection status varies between "Signal Strength: Excellent. Status: Validating Identity" and "unable to find a certificate to log you on to the network"
OR
sometimes with "Enable IEEE 802.1x authentication for this network" unchecked I get "Signal Strength: Excellent. Status: Limited or no connectivity"

I've an audit trail of everything I've so far tried during the past 3 weeks. I currently have "Status: Connected/Signal Strength: Excellent" with...

C:\>ipconfig /all

I can successfully ping myself (198.162.1.250) but nothing else including 8.8.8.8. However I can ping 198.162.1.250 from my laptop (as well as the Router on 198.162.1.254). I'm pretty certain there is nothing else on 198.162.1.250.

I feel sure this is not a Router nor an ISP problem but I suspect a fundamental Windows setting for out going traffic within XP I've missed.

Has anyone got any suggestions please?

Regards
 
First of all, I seem to have made some typos quoting 198.162.1..... They should read 192.168.1... I'm not at home at the moment and will need to recheck what I said above when I get home in a few hours time.

When you say do I have my "wireless set for windows", I'm not sure. Where is that done, please?

"when you connect with a cable can you ping then?" No, ping fails to return anything on cable and wireless.

I've looked at some of those google links but after a while I suffer from information overload. Those I've not looked at, I'll see if any of them are relevant.

Many thanks.
 
Turning On or Off the Windows XP Wireless Network Management

  1. Go to the Windows Control Panel and select Network Connections.
  2. Choose the Wireless Network Connection.
  3. Right click, and select Properties.
  4. Click the Wireless Networks tab.
  5. On the Wireless Networks tab locate the “Use Windows to configure my wireless settings” check box.
    To use Windows XP, select this check box.
 
Clarification: Upon re-reading my original post I need to correct my 'typos' regarding IP addresses. I inadvertently stated 198.162.1.250 as my XP's IP address. It should have read 192.168.1.250 with my Router being 192.168.1.254.

Here are some ipconfig and ping results...

I CAN NOT ping my XP machine (192.168.1.250) from the Laptop as previously implied. Apologies for misleading anyone. Although I can ping 198.162.1.250 where ever that is.

Sorry for any confusion.

you should see above after clicking properties on network connections, make sure there is a checkmark in internet protocol and click install, (even if it is already checked, you are going to reinstall

https://www.onlinecomputertips.com/support-categories/networking/286-reinstall-tcp-ip-on-windows

above is a little more detailed, but you will select protocol once the install dialog box opens.
 
Have executed the netsh commands

netsh int ip reset reset.log (see attached)
netsh winsock reset catalog
.... Sucessfully reset the Winsock Catalog.
.... You must restart the machine in order to complete the reset.

rebooted

which has resulted in "Signal Strength: Excellent / Status: Limited or no connectivity" and cleared out my IP Addresses and still shows I am connected to my 3Com Adapter

next run checkdisk

in cmd prompt type in

chkdsk c: /r

press enter

type Y for yes to run at restart, press enter, then exit and restart, checkdisk will run and it is a lengthy process depending on your disk size, if any errors are found, then run again, you can view report in event viewer/applications/winlogon

================

there is a checkmark in internet protocol and click install, (even if it is already checked, you are going to reinstall, even if the checkmark is there, click install anyway.

Hi Elizabeth

I've spent a bit of time reinstalling TCP/IP today but still further forward. To summarise;-

Starting with my manually entered IP addresses and with the 3Com Adapter recognised by Windows showing "Signal Strength: Excellent / Status: Connected"...

netsh int ip reset netsh-ip-reset.log

I discovered this sets "Obtain an IP address automatically" and clears out my addresses although it still shows
"Signal Strength: Excellent / Status: Connected"

upon reboot it picks up the changed settings and fails to find the 3Com Adapter...

"Signal Strength: Excellent / Status: Acquiring network address"
"The connection has limited or no Connectivity....." message appears and the Status changes to
"Signal Strength: Excellent / Status: Limited or no Connectivity"

I also selected the alternative method of reinstalling using the Wireless Connection Properties after reintroducing my IP Addresses but this didn't alter my settings at all after rebooting.

"Signal Strength: Excellent/Status: Connected"

To check my results I reran netsh int ip reset netsh-ip-reset2.log which had the same results as the first time.

I have recorded my efforts in Resetting and Testing TCP-IP on 10 Mar 2018.txt I hope it's not to difficult to follow.

Maybe you might spot something amongst all of this?

Kind regards

Rick

are you still getting any help at the above forum?

after some more research, suggest try the following:

Remove all the stored wireless network profiles and search for the network and enter the encryption key.

reboot and see if it works now, if not then next:

ipconfig /release

ipconfig /renew

in cmd prompt type the first, press enter, then type the second and press enter, check to see if working, make sure that the wireless zero configuration service is set to automatic in services also.

have you done the follwoing?

right click the current connection in Network connections and choose repair


===================

when you reinstalled windows, exactly how did you do this and what does it say on the cd used as installed media, exactly please.

=========

also any warnings or errors in device manager?
any errors in event viewer, need source and id number, please.
