IBM Thinkpad T40 Won't Connect With Wireless Card
Apr 12, 2011
I have an IBM Thinkpad T40 with Windows 7 Ultimate. I have all the updates from both Windows Update and Lenovo. Everything is working great except that I can't seem to get my wireless PC card to work still. It's a Trendnet TEW-421PC card. Windows found the driver for the card but it still doesn't work. I even downloaded the driver from Trendnet's website and installed it and it doesn't work. The "Activity" light blinks continuously and Windows detects the card but I can't seem to get it to connect to the internet. I had Windows troubleshoot it and it says there is a problem but none of the solutions seem to help. I can connect to the internet with an ethernet cable but sometimes I like to connect wirelessly.

I currently use drivers from 2008:Driver Version 4.176.75.21 - 10/1/2008 for my Dell Wireless 1505 Draft 802.11n WLAN Mini-Card.Whenever I run Microsoft Update it tells me to upgrade to the latest drivers, however, with the newest drivers I experience a SIGNIFICANT drop in throughput- something like from 108 mbps with my current setup to 1-15 mbps with the "updated" drivers.I'd like to have the most up to date driver, but do not want to limit my Wifi bandwidth either.

So i have windows 7 home premium (because this computer cant handle the features of ultimate anyway) build 7600 installed on an IBM thinkpad a22m. the video card is an ati rage 128. I have installed winxp drivers, 2k drivers, even 9x. every person i ask says its to old (which i choose not to believe) The drivers install, but it just disables them with error code 43. The same thing happened with windows 7 7100, and vista home basic on the same machine.

I've formatted the laptop and it worked great, but I saw that there was no wireless card and opened it to insert. I put a card from Dell laptop and when I turn on laptop, I got this error:
Error 1802 Unauthorized network card is plugged in - power off and remove the miniPCI network card.
I searched the internet and I saw that for this error, solution is updating/flashing bios with "whitelist removal". I did it and turn on the laptop and it worked normally, until I unplug the charger. Whenever I unplug it from the charger, laptop shut down immediately, just like it is without the battery in it. I tried to get back the original bios, but still the same. It shut down in Windows (7 32bit), in Safe Mode and in Bios. So the laptop is running great when I plug charger, battery shows a 100%. Previously battery held around 2-3h.

I have both x86 and x64 Seven installed. Wireless Card is Realtek 8185 b/g, router is belkin 802.11b
For x86, 7000-7048-7057 all connected to the 802.11b router with WEP 128bit without problem.
Since 7057, I installed x64 Seven and verified that the WEP key is correct. But, it just can't connect. "Unidentified network", Access type: No Internet access. ipconfig /all tells me that I didn't connect to the router at all. The router's dhcp didn't assign the x64 any ip.
If I boot up the x86, I then can go to Internet without problem.
I tried the troubleshoot. The program reset my wireless network card then let me retype my wep key. At the end, it was unable to fix the issues and it lists the problems as below:
Windows cannot connect to "....." Detected
"Wireless Network Connection" doesn't have a valid IP configuration Detected
Now, if I manually set a valid IP "192.168.2.3" and mask "255.255.255.0" and gateway "192.168.2.1", I still can't connect to the router. But, from the router side, the dhcp list shows my x64 ip address.
Also, even if I reset the router to Open (without WEP), x64 still can't connect to the router. None of above can make me ping the router. So wired.
Please help me. I do like x64 over x86, because in there the office 2007 and SAS 9.2 won't freeze/without response. And, I don't have the lan access to the router.

I cannot use wireless access, getting msg. wireless lan adapter has been disabled in device manager, checked device manager there is a Network adapter, (Realtek PCIE FE Family Controller) and then there is Other Devices under there is the network controller(yellow !). Downloaded controller drivers from HP,( sp53955) and for some reasons the drivers are not installing. Also when I try to set up a wireless connection all i can get is broadband and cable. I am quite sure this is because there is a problem with the wireless adapter.I continued my search and discovered that this notebook uses the Atheros ar9285 wireless adapter, I disabled the unknown network controller and enabled the Realtek since this one appeared to be the one that was installed by HP.

I'm running 7 Ultimate & have no problems at home but when I go out to my local diner I have no internet access. I have a great connection to their router but cannot connect to the internet. Once in a while,like maybe 1 out of 20x it will connect. I see folks on a weekly basis using the internet with no problems.

I have an Acer TravelMate 5740G (all other system specs are fine so i'm only posting the networking relevant stuff) and it does not connect to wireless networks - Acer Nplify 802.11bgn from a broadcom 802.11n wireless adapter apparently has the best driver (as advised by MS device manager)this pc has been able to connect to a grand total of 2 wireless networks?
1. at uni it connected on its own for 15 minutes, any time i've attempted to manually connect it says "could not connect to [network name]"
2. connected just fine to a 3g iphone 4 acting as a portable hotspot at home, my wireless settings are as follows:Open WEP PSK w/ 1 key index everybody else in my family can connect to this wireless network i can connect with my phone, my dad with his lappy, my friends with their lappies. there are NO xp computers in the network there are 3 Windows 7 desktops on the network the internet works just fine with the rj45 cable ---> i'm 100% sure the issue is not with my home network config OR the router at uni, the router + settings are not the issue because they service 15,000 people a day without issue ---> i'm 100% sure the issue is not with other network configs OR their routers i have tried every change under the sun (that i know of) with my laptop's own configs.i've attempted to update all the WNIC drivers, i've made the WNIC as open to connections as i possibly can.i have disabled ip6 and tried, i have enabled ip6 and tried, and i get no connections happening. i'm at the end of my wits, i just want my wireless to work, and i have NFI how to make it happen.

I've got a handful of Dell laptops that recently stopped reconnecting to a wireless network after being on the lan. WLAN shows connected, but can't reconnect until we do a IP refresh. Some machines are running Dell WLAN cards and another is running Intel card. Can't seem to nail down the problem. One user mentioned she was having this problem after MS updates so wondering if a patch/hot fix is jacking up these machines. To add salt to the wound, I brought my Dell Inpiron 1420 home today...plugged in the network cable..did some work, then decided to move to the couch.

I have a laptop (HP Compaq cq62) with Windows 7 64 bit and I have a strange problem with my wireless adapter. When I close the lid the laptop goes into sleep mode. When I open the lid and log in on my laptop, the wireless adapter can not find any routers. I have to go to my network settings window, disable my wireless adapter, enable the wireless adapter and then it is working.

I have 3 computers all running 64bit Windows Home premium all have 802.11n cards. 2 have no problem connecting to the wireless network the 3rd can see the network but won't connect or has the dreaded yellow exclamation mark with limited connectivity.
This seems to be a windows issue but not sure. When I look at the wireless profile in windows it says the security is WEP but the router is set up as WPA-2. I have tried changing the setting in Windows to WPA-2 but that then generates another error in the network discovery window saying the settings are not correct or something to that effect.
1) I have reinstalled the driver didn't work.
2) I have removed the security altogether didn't work.
3) reset the router didn't work (Although as stated earlier the other 2 computers connect with no problems)
4) Deleted wireless profile and started again didn't work.
The following worked untill I restarted the computer but would not after that even if I applied the same steps.
1) Assigned a static IP - This worked but once I restarted the computer it would no longer connect. Tired different IP address from 192.168.1-149. No joy
2)Copied the network profile from both the other machines same result as #1.

I have just set up a wireless network, and my phone (android) can connect to it fine with the correct wep key, but my laptop (windows 7) cannot. it sees the network but when I try to connect it does not ask for a wep key, it just tells me it cannot connect. I have tried going into the 'network and sharing center' and connecting manually but no dice.

I recently built my own gaming pc, spec'd as follows:
Asus Rampage IV Formula
Win 7 Ultimate 64 bit
I73930k
GTX 680
120gb ssd
etc.
I have installed Win 7 Ultimate 64 bit with no real problems. Except the internet connection! I have Sky Broadband which has a Sky router. I can connect my laptop wirelessly so i know it works ok. The only way my 'new' desktop will connect to the Sky router is by using an Ethernet cable. It simply cannot connect to it wirelessly.

I have an Acer Aspire v5-571 running Windows 7 Home Premium 64 bit, and I've been running into trouble connecting to my home's wireless network for the past couple days. It just says that my laptop is unable to connect. I've tried everything I can think of; I've reinstalled and updated all drivers from the Acer website, done system restores from weeks ago, installed all Windows updates, and I've even wiped my PC and reinstalled windows.
