Hello world,

I have on my PC (Win XP SP2, Symantec Antivirus 9.0, Zone Alarm 5.5) a 3Com card
(3CRPAG175).
Now it is about one week that I cannot connect anymore to my home router.
ipconfig/renew tells me: "unable to connect DHCP"
wireless network connection status shows 0 received packets
The signal is very strong but using firefox I will end up in no connection.

If I plug an ethernet cable no problem at all. I can surf, update programs etc. etc.


Any help/hints

Thank you very much

Hello Dodici and welcome to Geeks To Go,

I will first offer you the most basic troubleshooting steps to correct your problem and if it does not prove useful in correcting your problem please answer the second set of five questions.

20 Basic trouble shooting steps for No connectivity on Wireless Network:

1. Turn Off your Computer.
2. Unplug power from the Modem.
3. Locate the tiny button (about the size of a pencil lead) onb the back or front of the router - accessed through a tiny hole - now hold that button in for 20 seconds.
4. Unplug power from the router.
5. Plug power into the modem - wait for it to sync up (DONT MIX UP THE POWER CORDS FOR THE MODEM AND ROUTER - CAN DAMAGE THE EQUIPMENT IF YOU DO)
6. Plug power into the router and wait for it sync up (SEE NOTE IN STEP 5)
7. Turn on the computer
8. Click on START then CONTROL PANEL
9. Click on NETWORK AND INTERNET CONNECTIONS
10. Click on NETWORK CONNECTIONS
11. Locate the wireless card in the window and right click on it
12. Select VIEW AVAILABLE WIRELESS NETWORKS
13. In the Wireless Network Connection window that appears left click on your wireless router SSID broadcast.... (LOOK TO SEE IF IT HAS A LITTLE PADLOCK IN THE UPPER LEFT CORNER)
- - - If not.... then just click the connect button and then answer yes when it asks if you want to connect to the unsecured wireless network....
- - - If it does.... well then your router is faulty becaus in step 3 we restored it to the factory defaults...
14. Close out the Wireless Network Connection window and click on START
15. Click on RUN
16. Type in CMD or COMMAND and click OK
17. Type in... ipconfig andf hit enter
18. This should give you your correct ip address range of 192.168.1.101 or 102, 0r 103 depending on the number of computers on your network...
19. Type in EXIT and hit enter
20. Try to access the internet

If you have followed steps 1 through 20 and you are still unable to access the internet please answer the following questions for further help.

1) What is the Model and Manufacturer of the Wireless Adapter currently Installed on your problematic PC?

3) What is the Model and Manufacturer of the Wireless Router you are using?

4) Are you using the software that came with your wireless adapter to manage your connectivity to the router, or if using XP are you using the Wireless Zero Configuration (referred to as WZC)?

5) What IP Configuration are you using (Example.. DHCP, PPoE / Static, Automatic)
