I have been able to wirelessly connect my Inspiron 700m running win XP Home to the internet using a Linksys Wireless Broadband b Router BEFW11S4(ver 4). But I cannot set up a 2 Laptop wireless network to share files! I cannot even see my own computer in My Network Places!
My other computer is an ASUS M2400N (Centrino) also connected wirelessly to the Linksys. From the Asus, I am able to ping 192.168.1.1 (the router), the Asus machine itself but not the Dell. Using the
As for the Dell, I can ping the router, but i cannot ping myself or the Asus.
For some reason, it appears there are 2 Network Adapters (Broadcomm 440x 10/100 Integrated Controller and Intel(R) PRO/Wireless LAN 2100 3A Mini PCI Adapter), and each having its own IP Address. Could this be what is causing the problem? HELP!
The Broadcom network adapter is the wired ethernet adapter in the laptop. If you are not using it you can right click on it and select Disable. The icon will no longer appear in the notification area. The Intel Pro/Wireless adapter is the wireless network adapter in the 700m. Having both enabled will not cause any problems.
Make sure any software firewalls running in the 700m are configured properly. The Windows XP SP2 firewall should have File and Printer Sharing checked in the exceptions list. If you are running any third party firewalls like Norton Internet Security, McAfee Security Suite, Zone Alarm, etc, they need to be configured to allow access for File and Printer Sharing. These products typically provide for a Trusted Zone, an IP address range that allows access. Configure this IP address range using the same address range being assigned by the router. Most likely your BEFW11S4 is issuing IP addresses in the range 192.168.1.100 - 192.168.1.150, the default. Norton AntiVirus 2005 has a worm blocker which acts like a firewall.
I have a similar problem and followed the instructions above.
My main PC is directly connected to the router Dell Wireless 2350. My laptop is connected wirelessly. Both PCs get internet OK and the main PC can access shared files on the laptop. However, the laptop gets an error message saying the main PC is not accessible and contact administrator to arrange access permissions. I have tried disabling Norton (although it is only NAV2003) and spybot and windows firewall and zone alarm but this doesnt work. Please can I have any other suggestions as to what is causing the problem.
Thanks
PS How secure are internal networks. Once set up, you need to allow the firewall to byepass connections from the other PC which seems to have an IP address that is not unique. What is to stop someone from the internet pretending to have the same IP address and getting in that way.
In the future start a new thread. It gets too confusing troubleshooting multiple problems in the same thread.
NAV2003 is antivirus only, unless you are running Norton Internet Security. You should re-enable NAV2003. Simply disabling Zone Alarm will not disable its firewall. To do that you either need to uninstall it or properly configure its Trusted Zone. ZA is well documented in its user manual, downloadable from Zone Labs. The Windows firewall should be configured with File and Printer Sharing as an exception (checked off in the exceptions list in SP2) or disabled in SP1. Spybot is not a firewall.
Wired internal networks are very secure. The router acts as a firewall so unsolicited internet hacking is blocked. The router cannot help with outgoing traffic from a trojan on the PC. That's why a software firewall is useful. Wireless network security is always iffy. Given enough time a persistent hacker can get into a secured wireless network. But with so many unsecured wireless networks out there, a hacker is going to spend his time there and not on a wireless network that is properly secured with WPA or WEP, SSID broadcast disabled, and MAC filtering.
Each PC on your network has a unique IP address, otherwise you would be getting IP address conflict messages. They are probably similar to each other, except for the last few digits.
Double check the firewalls - you should only be running one software firewall - and if the problem is not resolved post a new thread explaining the problem and include as much detail as possible about your network.
