Hi everyone: I’m having an extremely frustrating problem connecting to my Netgear DG384G v3 wireless router in my flat.

In short:

Ever since I reformatted my hard drive and reinstalled Windows XP Pro, internet browsers do not detect a connection to the internet despite a wireless connection being detected in the network connections (and the icon in the system tray) when my wireless adapter is plugged into my PC. Connection problems only occurred after the reformat, another PC in my flat connects wirelessly to our router with no problems (before, during & after the time I reformatted; I’m posting this using his PC) and the router config settings have definitely not been changed in any way so its not a router problem. It appears that the wireless adapter is able to detect a signal from the router but the router is not sending information to the adapter (I can’t even connect to the router setup IP address 192.168.0.1)?

More detailed:

1) I wiped the PC’s harddrive then reinstalled Windows XP Pro – I thought the recovery disk would have drivers with it (like others I’d used) but it didn’t so I had to manually find nVidia chipset & 3com Ethernet controller drivers and SP1 (for USB 2.0 functionality), download them on another PC and transfer and install them on mine. I got SP2, this didn’t change anything, I changed back to SP1, still no change to connectivity.

2) When my Netgear WG111 v2 wireless adapter is plugged into a USB port, Windows recognises it as a device connected to the PC.

3) My Netgear DG384G v3 router is working normally – the power light is on, the internet light is on and the wireless light is on, all are green, the internet light blinks intermittently as normal, the other two are solid.

4) When the wireless adapter is plugged into the PC, wireless networks are detected and I can detect and connect to my Netgear router using the same WEP key and SSID as before (set at the time of router setup and not changed since). Bubble comes up with “Wireless Network Connection 2 (NETGEAR), Speed: 54Mbps, Signal Strength: Very Good”

5) When a browser is opened and set to any website the DNS error screen (“The page cannot be displayed, The page you are looking for is currently unavailable” etc) in IE, “Server not found, Firefox can't find the server at www.google.co.uk” in Firefox

6) When opening Internet Explorer, the bar at the bottom of the window displays “Detecting proxy settings” for a few seconds before the DNS error comes up.

7) The router settings cannot be opened via a browser, either by using the router setup CD or by typing http://192.168.0.1 into the address bar. The same error msg is displayed in IE, Firefox displays “Unable to connect, Firefox can't establish a connection to the server at 192.168.0.1”

8) I can connect to the router setting page in the above way using my flatmate’s wireless connection to the same router.

9) Opening up the properties of the wireless connection shows that data packets are sent but not received, e.g. after leaving the wireless connection on for 4 hours – 15000 packets sent, 0 packets received

10) I tried bridging the wireless connection with the 1394 Net Adapter connection in “Network Connections/LAN or High Speed Internet”, this had no effect. reversing this also had no effect.

11) All settings (IP etc) were set to be automatically provided, no effect.

12) I looked at my flatmate’s connection settings (IP address, subnet mask, DHCP server etc) and manually specified as many of them as I could on my connection, no effect.

13) I used my flatmate’s connection to go into the router settings and manually specify my PC’s Physical address (MAC no.) as being always allowed to connect, no effect.

14) I effectively turned off the router’s firewall (by setting it to allow incoming connections on all ports), no effect. Changed it back, no effect.

15) I removed the WEP, no effect (not likely to be the cause anyway, since I can connect to router using the WEP key as described).

16) All other functionality of the PC is 100% normal; no devices are listed as not having drivers installed in device manager. PC is running SP1, ISP is AOL though I have been unable to find the AOL CD so I’ve not tried reconfiguring with that (but I didn’t use the AOL CD to start-up in the first place when the internet worked before the reformat)

The fact that no data is being received in the connection properties thing seems to suggest that the router is not recognising the PC or some such thing that is preventing the PC access the internet connection despite detecting and apparently connecting to the router’s wireless signal. Perhaps some networking device is not working / hasn’t had software installed for it?

I would appreciate it if anyone could help, if I’ve left out any information you might need to solve the problem them please let me know. I’d also like lists of any possible things it might be (e.g. suggesting to check the firewall even though I’ve said I’ve checked it and it didn’t have an effect) just incase I’ve missed something on one of my checks that someone knows to have caused a similar problem from experience.

I’ve not yet tried wiring the router into the back of my PC since that would involve temporarily moving the PC into the living room and since the problem doesn’t appear to be with the router and it’s the wireless connection that’s giving problems I don’t see what wiring it up would achieve, even if it could connect to the net that way. Of course if I’m wrong, please let me know & why connecting to the router via an Ethernet cable could help my wireless connectivity when the router is setup and working already.

I’m all ears.

Kind Regards,
Michael Barker

can't log on to domain when ethernet cable is plugged in. If you unplug the ethernet cable, you can log on as if it were on the domain, plug the cable back in and you have access to all resources. Have any of you seen this? Thanks
Sorry, not sure if that's a suggestion of what I should do or a question that you are asking for an issue of your own?

Also, how do I explicitly make sure the computer is set to obtain IP's via DHCP? Just in case I missed this when I thought I'd set all settings to be automatically attained.

Another thought:

If I manually specify the IP etc settings to ones that are correct and thus should allow the PC to connect to the net wirelessly (ie the effect of having the correct settings automatically provided to it by the router) but it still doesn't then what does this mean? (pt12 and what I expect to happen again if I make any IP changes as has been suggested on other forums, not had a chance to try them yet).

Is there a software or hardware component/setting that would somehow stop the router recognising the PC's presence or stop 2-way communication between the PC and router even tho the PC can detect the router's presence with the wireless adapter and connect to its wireless network using the WEP key?

I have a feeling the problem lies in this area, also maybe to do with the fact that due to the reformat the PC effectivly has the earliest version of XP-Pro running with SP1 installed & no other windows updates from between XP's 1st release and SP1's release - was there a later Windows update between XP & early SP1 and SP2 that might have adressed something like this? Before the reformat the connection worked fine on a system that had all the updates post-SP1 but not SP2 or any of the post SP2 ones (due to a registry problem stopping SP2's install, the reason I eventually went for the reformat).

Windows IP Configuration

An error occurred while renewing interface Wireless Network Connection 2: unable to contact your DHCP server. Request has timed out.


I’m guessing this gives some indication of the root of the problem? I should probably of noted that when I was manually specifying the IP address etc I couldn’t find a menu for specifying the address of the DHCP server, tho the connection was set to be DHCP enabled. The DHCP server on my flatmate’s connection to the router is 192.168.0.1 (the router’s IP address), that address along with the DNS etc are all provided automatically on his PC.

If a possible solution to this involves modifying the DHCP address or settings could you please explicitly say what menus these settings are changed in because I couldn’t find any DHCP setting menus when I tried to manually specify all of the addresses, I have to access the internet on other computers so this just saves time because I can only check the forums a few times a day.

Thanks again.

Possibly an issues with the router configuration??

Try a static IP address in the remote machine as the 169.x.x.x address means for some reason a valid IP address has not been assigned.

Something like 192.168.0.165, Sub Net Mask 255.255.255.0 and Default Gateway of 192.168.0.1 might resolve your problem?

If the same router works fine wirelessly with my flatmate's PC, does this not rule out a router configuration problem?

Also, the same router worked fine with my PC before I reformated it (as stated) using the same USB wireless adapter with the same driver and same firmware, indeed the router was setup using my PC a few months ago, the only configuration my flatmate had to do to set up his connection was intall his adapter's drivers and plug it in.

I'll obviously try what was suggested but the fact that the connection worked fine before and currently works fine on a different PC seems to point towards some sort of configuration issue with my PC, especially if the IPCONFIG/RENEW failed in the way that it did and the adapter is being asigned a generic IP because the router wont give it a valid one and the network properties thing is showing that no data packets ar registered as being received, depsite them being sent.

question: what software are you using to control the wireless NIC?

built in XP software?

if so, disable that and try using the manufacturers software

im sorry if this was mentioned already but im in a rush at work and dont have time to read the whole thread

I've tried both: with the Netgear software and using the XP wireless control thing, same thing happens with both.

Is there some sort of application or client that XP uses to control DHCP and/or DNS function? If so, could it be possible that because my platform is (since the reformat) essentially a very early copy of XP-Pro that ONLY has SP1 installed on it and no other updates whatsoever that this DHCP service could either not be installed or not functioning in some way? If this is the case any ideas on how to find the relevant files for downloading, ie from Microsoft or just go for googling them.

Thanks

Well I can't connect to the internet (obviously!) to us the Windows update system, so any updates I'd get would have to be downloaded manually on another machine then transfered via memory stick to my PC for installation.

The reason I went for the reformat in the first place was that the PC hadn't been connected to the net since before SP2 came out (long, irrelevant story)so was still on SP1, I installed SP2 as soon as I got it on the net but there was a problem with the installation, I removed SP2 and tried to reinstall but a single registry key had become corrupted and so couldn't be removed or overwritten thus stopping SP2 from being installed.

I just left it on SP1 for ages, then decided to give up trying to fix the registry key and just wipe the whole HD and start again with a clean install of XP - I assumed the Mesh recovery-disc would be a disc that would effectivly reset the PC to the factory settings, with all the drivers etc but it turned out to just be an OEM XP-Pro disc and nothing else! After manually searching for, downloading & installing the drivers that weren't on the driver backup disk I tried to connect but found there was no USB2.0 support, found out the version of XP I had was pre-SP1 and so got SP1 for the USB support.

Since my PC before was on SP1 and the connection worked fine, unless SP2 is also culmative of every single windows update that came out prior to SP2 I don't want to risk clashes where some parts fo the system will be more updated than other bits (if updates etc for them are not manually installed).
I installed SP2 but this didn't have any effect on the connection so I then uninstalled it for the reason above.
