Dell 1397 WLAN mini-card can't find internet connection

I've got a Latitude E6500 laptop with Windows 7, 64-bit.  I've tried connecting to three wireless networks and each time the wireless card manages to connect to the router, but is unable to connect to the internet.  When I connect using the ethernet I have no problem and I'm able to connect to the wireless using other devices.  I've downloaded the latest BIOS and windows drivers.  I've ensured the security is configured correctly, the wireless is on, the password is correct.  Why is this such a headache?

Re: Dell 1397 WLAN mini-card can't find internet connection

If possible,  I would temporarily remove the Wireless Security from your Router and see if you can get connected through Wireless.  Once you have established a wireless connection without security, you can proceed from there and re-establish wireless security on the router and client.

You should only be  using WPA2-PSK  AES and NOT WPA or WEP

Re: Dell 1397 WLAN mini-card can't find internet connection

I have been looking for an new driver for this network card, the driver that is shipped with the new Dell's in not compatible with Windows 7, or the wireless card is not compatible with Windows 7. When upgrading to Windows 7 after running the verification utility the WAN card comes up as incompatible? There seems to be nothing posted on the site referring to this as being a problem?

Re: Dell 1397 WLAN mini-card can't find internet connection

I'm having the exact same problem with my Inspiron 1440.  It too is Win 7, 64-bit.  Like you I've tried updating drivers, quadruple checked all settings etc.  I took the notebook to Best Buy and they connected right away to their wireless.  I took the machine to my workplace, and it also connected there.  I tried an Ubuntu live CD with no luck at home.  I tried setting up a different brand of wireless router at home, but still no internet.  Then I disabled the 1397 WLAN mini-card and plugged in a spare USB wi-fi dongle.  I finally was able to get to the internet.  This has caused me quite a lot of frustration.  It just shouldn't be this hard.  So here are my choices:  1)  Let the notebook have a USB thingy sticking out the side;  2)  Take it back to Best Buy and pay a probable 15% restocking fee;  3) Research and find out what routers are being used at Best Buy or my workplace and buy one of them.

Same problem with the Dell Inspiron 1750.   There is some kind of problem running Windows 7 with the WLAN 1397 wireless and there have been no new drivers posted to the Dell Drivers and Downloads site.   I would suggest to anyone placing a new order to make sure you avoid the WLAN card.

If anyone has a solution, please reply.

Re: Dell 1397 WLAN mini-card can't find internet connection

I am new here, so don't chew me up. I just, as of 7/23/10, received an Inspiron 1750 with the same network wireless card in it. I have a Wireless Cisco WRT160NV2. I have a PS3, a Wii, several laptops and PCs on it running both wired and wieless connections running any anything from W2000 to now this Windows 7 that came on the new laptop. I have the same problem. I have been dinking with this for hours now. I have tried all the obvious paths, no firewall, Autoassign on the DNS, opened the router up without security and I can not connect to the router at all, The laptop "sees" the router but I can not connect to it. There is another unsecure router somewhere in my neighbor hood that I can connect to. Which makes me think there is an issue between Dell and the Cisco. Any ideas on this as well as what you were experiencing? Did you get a resolution yet?

In my case, I had to get a new WiFi-Card for the 1750...

Look for latest drivers for the wireless adapter

Look for a firmware update for the router

I would download WireShark and do a packet trace.  Is it just not "seeing" your wireless router or is it seeing the router but not receiving an IP address?  Start from the basics and go from there.  Make sure you have enough IP addresses in your DHCP IP Pool. 

Hope this helps narrow it down.

Re: Dell 1397 WLAN mini-card can't find internet connection

 John Nashville,

 

Some of the network cards work better when you go to the device manager, click on network, your wireless adapter, advanced and change the Antenna diversity from Auto to AUX.

 

What type of security are you using on the wireless router? Try channel 11? Try mixed mode?

Re: Dell 1397 WLAN mini-card can't find internet connection

Thanks for the responses.

Status - WellI guess I can mark this one down as, " Owner got too excited about his newlap top and went stupid". Yeah I know, doh. It should be noted that this Refubished Laptop did not have any real documentation with it and I am new to the Windows7 world. Things are a bit different in Win7, but hey for $389 whatcha want?

Anyway the resolution for me was as simple as entering the MAC address of the new LT, into the Linksys MAC filters section of the Linksys software for the WRT160NV3. And I do not mean the Linksys Advisor, use the browser and eneter 192.168.1.1.  Complete connection suddenly after that, go figure.

To find your MAC addresses in WINDOWS7, go to the START button and in the "Search programs and files", space to the left of the "Shut down" button, type in "CMD". In the black box that pops up, enter this, "GETMAC" and press ENTER.

Presto,  your Physical Addresses, or MAC addresses,  are displayed.

 As a note, in my case, the following is true:

All firewalls, spam filtering, etc., in Windows7 Home Premium are enabled.

Security on the router is setup for WPA-Personal (PSK) and of course with Wi-F1 Protected Access Password.

I am broadcasting the SSID, not a big deal.

Both IPV6 and 4 are enabled in the connection properties for the 1397 WLAN mini-card. No sharing is setup since I have the only WIN7 system in the house.

Driver in use is the stock driver, Broadcom 7/7/2009 ver 5.30.21.0

Otherwise, I do not recall any other changes I made to the default settings. All the Advanced setting are default 

 

 John
