From: Tomi H�s� on 8 May 2008 07:53 How is it possible that my D-Link modem is working with one of my Windows XP computers, but not with the other? The computers have about the same software, but different manufactures. So, my D-Link DSL-G624T wireless ADSL modem router is only working with my Fujitsu Siemens Amilo L7310GW laptop, but not with my HP Pavilion dv5037A laptop. The HP laptop still works with my old ZyXEL Prestige 660R-61 modem, so is my HP laptop blocking the MAC address of the D-Link modem router or something similar? I have tried these with my HP laptop: 1) Scanned for viruses and spyware with Avira AntiVir PersonalEdition Classic 8, Ad-Aware 2007, Spybot - Search & Destroy and Windows Defender. 2) Emptied the cache and deleted cookies for all my web browsers. 3) Went to address 192.168.1.1 (D-Link address) and got "Internet Explorer cannot display the webpage". 4) Pinged 192.168.1.1 and got "Request timed out.". 5) ipconfig /registerdns 6) ipconfig /flushdns 7) ipconfig /release 8) ipconfig /renew 9) netsh winsock reset 10) restarted my computer 11) restarted D-Link 12) reseted D-Link 13) restarted my computer

Possibly the other way round. Check that the wireless encryption settings are the same on both laptops. Connect to the router with the laptop that works and check what wireless settings are required and if mac access control is enabled. What response do you get from ipconfig /all Jim.
From: Jack (MVP-Networking). on 8 May 2008 20:05 Hi It might be that the computer is configured to work with the Zyxel with static IP that does Not match the D-Link sunbet. Male sure that the HP is set to obtain an IP automatically and that the D-Link Router DGCP is On. Jack (MVP-Networking).

According to the "ipconfig >/all" info (when using D-Link) the subnet masks are incorrect -- how do I >change them? You're getting an apipa address and mask which is what the computer defaults to when it cannot connect with the dhcp server. That's not the problem. It just confirms it's a wireless problem probably with encryption. You say the settings are the same on the working and not working computers. What are they specifically? And what is the router set up to use? If you're using wpa-psk encryption ensure you have the correct setting for aes or tkip. Some hardware can't handle aes so you might have to use tkip. Jim.

With D-Link I tested several different setting combinations one by one, for example I enabled DHCP Server, then Virtual Circuit, and finally NAT, and then connections with both of my computers worked except the _wired_ connection with HP laptop, so I looked what was different and enabled "Client for Microsoft Networks" and "File and Pinter Sharing for Microsoft Networks" in Network Connections, but what is strange is that my ISP told me to disable them in Windows in year 2007, but maybe the ISP's network settings have changed again. My D-Link DSL-G624T might have a bug when you try to use WEP. First of all, I can't make D-Link's WEP work (I have tried 64bits and 256bits WEP keys with both of my computers), and when I change back to WPA, all my connections, wired and wireless with both of my computers stop working. Only restarting (unplugging power adapter and then plugging it in again) D-Link seems to work (restarting my computers isn't enough). And, by the way, here are my network related settings in both of my Windows XP laptops in case someone is interested in them: (1) _Wireless_ Settings Control Panel: Network Connections: Wireless Network Connection: General [x] Client for Microsoft Networks [x] File and Pinter Sharing for Microsoft Networks [x] QoS Packet Scheduler [x] Internet Protocol (TCP/IP) Wireless Network Connection: Internet Protocol (TCP/IP) - Properties - (*) Obtain an IP address automatically - (*) Obtain DNS server address automatically - Advanced - IP Settings: - DHCP Enabled - [x] Automatic metric - DNS: (*) Append primary and connection specific DNS suffixes [x] Append parent suffixes of the primary DNS suffix [x] Register this connection's addresses in DNS - WINS: - [x] Enable LMHOSTS lookup - NetBIOS setting: (*) Default: Use NetBIOS setting from the DHCP server.
