Wireless addresses

[Crumlin]

Have got a laptop with wireless problem. Rarely picks up an IP address on wireless when using DHCP. This occurs on any wireless network, have tried a few. Switch it to static though and the connection is rock solid. It has a strong signal, I'm sat next to the router trying it now, but sticks on acquiring a network address. As I said, sometimes it will get one, then vanish just as quickly. Thought DHCP might be poorly on the laptop, but then surely that would effect it on the LAN too, which is working perfectly.

Haven't got the luxury of wiping it, and have tried grabbing the latest drivers for the wireless NIC, still nowt.

Answers on a postcard please

The winsock entries can sometime get corrupted and cuase this problem.

Firmware upgrade on router? Reboot the router?

It's all wireless routers, don't think I can do them all

Cheers BM, I'll give that a go.

Ello,

Have you tried the usual - update the drivers for your wireless card, check all the settings for it in the OS and the BIOS.

Also try re-configuring it to use a different wireless channel - might be something in the environment (PCs, TV, Microwave(!) etc) that is malleting that specific frequency...

Worth a shot.

Just a thought...

is the wireless router set to be the DHCP server? If that's set to off/no/disabled then that might be part of the problem.

Have you got an RJ45 netowrk socket on the wireless router? If so just plug in to ensure DHCP is working as expected on a wired connection. It could be fooked

DHCP on the router is not properly set.

After you get an IP, do

ipconfig /all

if your OS is Windows. Then check for how log is the IP address leased.

I don't know what all this dchp ip talk is about but it all sounds very impressive...
