Dead laptop - bad wifi card or ???

Hi all,
Oddball question: I have a Lenovo t410i that is completely dead. About two years ago, I dropped a bit of water on the keyboard, and something got fried so that the keys wouldn't type correctly anymore. When I went to replace the keyboard, I accidentally ripped one of the cables from the Intel Wifi Card (model 622anhmw). When this happened, the laptop would not power on. After two years, I am finally sitting down to try and fix this, but before I go buy a new wifi card (the cable was ripped out with the solder connection), I wanted to ask if anyone out there knew whether simply replacing the wifi card will actually solve the problem.
Seems like it's a pretty strange thing for the laptop to route all power through this tiny card, but I've seen stranger things.
Thanks!

My WAG is a blown fuse (if there are any in that laptop) or something else that got yanked on and shorted when the cable was ripped out.
You'll need one of the members, mods, or gurus her on the forums with repair experience to offer advice. Sorry, it's above my pay grade.

Bad wifi card macbook?

I use a late 2008 MacBook. My wireless internet connection seems to time out and slow dramatically from time to time. If I turn the airport off and then back on, it seems to get it going again. I use ATT U-verse and our connection is typically extremely fast but lately the speed has been intermittent and won't load webpages. However, when I connect my computer directly to the router via ethernet cable, the speed is constant and the problem goes away. Is this a sign of a bad wifi card?

Not necessarily...if the card failed, you'd most likely not be able to use it at all. Which protocol are you using to connect? It may be useful to delete the current network 'location' and recreate to see if that helps.

Lenovo yoga 213 wifi card not working in the new laptop

I purchaed lenovo yoga 213 from Best Buy Boston and have brought to India.From the day one,the Bluetooth and Wifi is not working.On taking to their authorised service centr-Hitech technologies they have tried to replace the wifi card but even they are not able to solve the problem.I am trying to contact Lenovo for replacement of Laptop,but there is no response from them.What should I do?

Lenovo service centre has done all these after getting a replacement card
from Lenovo and again they have reported that the wifi replacement card
recieved is defective ,so they have asked for 2 nd time replacement of
wificard as well as the touchpad which they say carries the antenna for
wifi.The bottom line is i am tired of running around to service centre and
have not been able to use the laptop from the time i have bought the
laptop.I thought if there is a manufacturing defect lenovo,being a reputed
brand will replace the laptop.

DV6 6167cl - Dead WiFi Card After only a few months

I've only had this notebook since summer of last year (11) and already the network card is dead. I've ordered another part from the parts store but if you ask me it should be free of charge. Has anyone else had trouble with the WiFi card in the DV6.
No matter what I do I can't enable wireless. I've tried everyting - pushing the f12/wifi enable button countless times but it just won't turn blue. Lucky for me I have a Linksys USB WiFi handy or I'd have no Internet for a few days at least.

Upgrade Wifi Card in my Satellite Laptop Help.

So our cable/Internet guy come out to our house to fix the internet, when he was done he did a test on all the computers, all were fine accept this laptop. The wifi speed is only pulling in half of what all the others are, even if we hold it directly next to the router.
I want to upgrade the wifi card to something that can take more advantage of our high speed interent, but i have little experience with laptops. I have been building and repairing my families desktop PCs for years, so i do have some experience in this area though.
i did some reading on how to phisically replace the card, so i can probably handle that pretty well, my real problem is finding out what cards are compatable. I can't find any detailed enough specs to find this information, such as, does the wifi card in this laptop use a PCIE slot or something else? Are there different size cards i need ti look out for, and i read something about BIOS white liisting.
One article said some manufatcurers black/witelist some hardware, and i was told to check and see if i can find if this is so, and if i can find the list. I would apreciate any help with thiis issue, thanks.
Anyways, my laptop version is, Satellite Toshiba C875D-S7331

I would love to see that list also I replaced my card with an azurewave broadcom card mod BCM94352HMB I can now connect at 866 mbps on AC but have found no way to get bluetooth to work the different driver installs tell me to turn on the Bluetooth I could not find anything in the bios to enable. The card is a 802.11/ac/867Mbps WLAN+BT4.0 half mini PCI-E.
computer is a S855-S5254....Both win10TP and 8.1 installed the proper broadcom driver automatically but I have not figured out the BT yet. This card picks up wifi better than the realtek that was original. I have read a lot of complaints on the intel cards so I went this way.

Faster WIFI Card for Toshiba L455D Laptop

Looking for a wifi card to replace the ATL8187SE card in my L455D. My reason for wanting to do this is because the 8187 max. download speed is aroung 20 Mbps and I need a card that can double this speed so I can take advantage of my 50 Mbps provided by my internet provider.
Thanks

Not sure what the issue is that's resulting in a change for you. However, the MBP's wireless reception has always been comparatively poor relative to many other laptops. It's not a Mac issue per se, it's the aluminum casing, which blocks the wireless signal whereas polycarbonate does not. MacBooks (non-Pro) get significantly better reception than MBPs with the same wireless card.
Nevertheless, to answer your question, here's an ExpressCard 802.11n adapter and a cheaper USB 802.11n adapter that will work with your MBP.
Hope this helps...

Compatible WIFI card for Thinkpad a21m, wifi orinoco silver no longer working

Thank you for having this forum available.
My husband passed down his Thinkpad A21M Type 2628-GTU to our son. The wifi card that was with it is a Lucent Technologies Orinoco Silver 11mbit/s t/n 03549501 p/n012938/c. When powered up last night, the ethernet was fully functional, but the wireless card didn't connect to the net. My husband assumed the Lucent card was bad. Is there something compatible I may buy to replace it? Do you have a suggestion on what he might have missed in trying to get it to work at home?
He has used this laptop all over the country including at home before, so I would imagine he knows what he is doing. But, we do have a new service provider since the company upgraded his computer system.
Thank you so much!

Welcome to the forum!
Honestly, it's time to upgrade to a newer card anyway, at least b/g. Any PCMCIA wireless card will work with your A21m, it all depends on your router, and your personal preferences.
Hope this helps.
Cheers,
George

Ralink RT3290 802.11bgn Wifi Card - Possible Issues [SOLVED]

Dear Lucky owners of such a card, At least from my experience I realized it is not that bad card, even if most probably many production pieces were faulty or not working properly, and many issues can be resolved. Let me list in order of time the issues I faced and solved about this wifi card: 0) First issue is not about RT3290 card itself but it is related to 802.11w encryption compatibility in between Windows8 and Cisco not allowing 802.11n speed rates so failing to G speeds only. - SOLUTIONS: a. As first test I would recommend trying another router from different brand to see if connecting at 802.11n speed rates b. If you prove point a issue, then try to fix the issue based on following post (in which you can see the reply from myself Emanuele on the 29th of Nov 2014): https://supportforums.cisco.com/document/113836/windows-8-clients-cant-associate-cisco-unified-wireless 1) Signal strenght issue: original wifi card RT3290 installed on my HP laptop was having really bad antenna, with signal fluctuating and sometimes bad even really close to any Router I tried. - SOLUTION: Replace the RT3290 card even with same new card. (In my case as laptop was under warranty, I proved the issue via screenshots and they replaced with new card solving my signal strenght issue). 2) Original issue (1) was actually resolved after HP replaced the wifi card with same model, but with the latest driver installed 5.0.45 seems like wifi rates change too frequently based on high sensitivity of the driver itself, so that suggested me issue was still there, so making me re-testing anything from scratch. - SOLUTION: Install 5.0.37 Driver - frequent rate changes issue (with driver 5.0.45) disappears and sensitivity of signal to rate changes seems to be a really good compromise to have good throughput. 3) To check out 2nd issue above I started again using a third party software inSSIDer free version to check signal while I was doing speedtest on web.
- RESOLUTION:
inSSIDer normally works on Windows7 without any issue but on Windows8 (at least tested with RT3290) I have just discovered somehow this software was slowing down wifi card performance drastically showing a speed up to 0.1Mbps rather than 40Mbps. Simply closing the application issue was not recurring, so uninstalled it and after solving all the other issues above this card works perfectly (at least so far ) Hope this post will be informative and will help other about-to-get-mad guys as me

Hye. After I read up your solutions, I am quite impressive and really want to try out those solutions. However, I am not very computer wise and I really appreciate if you make a video on solving this problem. Up to you if you want to upload it on the youtube (so that others with similar problem can view it and solve the problem too) or you want to direct email to me ( [email protected] ). I really hope you can help me because I am stuck with this problem since last year. Thank you!!!

Bad WiFi reception

Hey!
I have a K8N Neo2 Platinum wich included a WiFi card. With the included antenna, I get a horrible reception. I get a low to very low reception in one area where I get 90% with my laptop with built-in antenna! Is there something wrong with my antenna, is it just a bad antenna, or is there something wrong with the PCI-card? What can I do to improve reception??
Thank you for all help!!!

got the same problem, if you want you can build a custom antenna (blueprint on the web) that can help. For me i just got a Wireless accesspoint, case solved... last time that i buy a board with integrated "solutions"

2180us wifi card update? New card not on white list

I bought a dual band 802.11ac card with the intention of updating the single band 802.11n card in my laptop. It is a dm4-2180us. When I put it in I discovered that the BIOS will not boot the computer. I since learned that the BIOS has a white list of acceptable cards. All others are prevented from booting. All seemingly from 4 years ago!
What options do I have to go to 802.11ac dual band? Is my otherwise perfectly fine laptop stranded with sub par networking?
I have two of these laptops and two of these cards I cannot use.
I am frustrated.
-Tom

So, it seems that HP agrees that the white list was a bad idea in that they no longer do it. But that does not solve the problem for people who have laptops from that period. My understanding is that a lot of the BIOS's have RSA keys, so that it is impossible for a user to modify them. Actually I have looked for a modded BIOS for this model and it seems to not be avialable.
Also there are no cards avilable that offer ac or dual band. For that matter how would I know what is on the whitelist other than a handful of cards from 5 years ago.
HP is still updating the BIOS from time to time. Mine is in the file sp60704.exe (01651.fd). It is probably a 2 line code change. I wish they would supply an update removing the white list.
I'd get a USB dongle but the machine has USB 2.0 and that is actually slower than the new wifi cards. Also USB has its own throughput issues, even if I had USB 3.0 it would run slover than the max data rate.
I feel that HP owes buyers of these older machines some kind of a fix. Especially given that their policy is to not implement white lists in BIOS anymore.

[SOLVED] Problem with Networkmanager and two WiFi cards

I have two WiFi cards, one onboard my laptop, one USB. I use the USB one since gets a stronger signal, but the other one tries to connect.
Is there a way of stoping that.
I don't want to cancel the possibility of using it, just when I plug the USB antenna.
Thank you

Thanks for the reply.
This is what I get:

Hard blocked: no

Soft blocked: no

2: phy0: Wireless LAN

3: hci0: Bluetooth

4: phy1: Wireless LAN

If I try to "block" either number 2 or number 4. The WiFi disconects. It's as if they were the same card.
Any ideas?
Once again thank you

Yoga 2 11 support for new AC Wifi card

I just recently upgraded my Yoga 2 11 with a new Crucial MX100 512 GB SSD. While in the laptop, I pulled the factory Wifi card and bought and installed the Intel Dual-Band Wireless AC 7260. I get the dreaded error on bootup that it has detected a unsupported wi-fi card. Is there a supported AC card for this machine, or plans to support this Intel card?
The top card is what came from the factory (real piece of junk), and the bottom is the new Intel card.

Have you considered looking at what's available in the Lenovo Outlet ?
Here's one example, Y11s Haswell: http://outlet.lenovo.com/outlet_us/itemdetails/59RF0542/445
Listed as a refurb. My experience with refurbs from the outlet is that I couldn't tell them from 'new'. YMCV.
Happy Hunting!

[GAVE UP] New Wifi card problem - no orange "Wifi on" light

For some silly reason the Intel Wifi 4965 agn mini-PCI card in my wife's laptop will not work with anything newer than Ubuntu 8.04 Hardy Heron. Linux will not even "post". (I think that's the right word) So, I ordered an Intel Wifi 5100 agn mini-PCI card as a replacement.
When I installed it, Linux recognized it (hooray!) but will not use it. (boo!) The dmesg output says that the radio is disabled by the hardware switch. (the physical switch on the case of the laptop) Also, the orange "Wifi on" light does not light up any more.
Physically, the new card is an exact replacement for the old one. I don't think the two wires are on backwards. (they are labeled) I did not see anything in the BIOS related to Wifi. Toggling the switch off and on does not help. It is a Toshiba Satellite A215-S5837 with an AMD Athlon64 processor.
Has anyone experienced this problem?
Does anyone have a suggestion of what to try?
Thank you!

Thank you for the suggestion. I installed the firmware, the modules were loaded correctly, and the OS detected it, but it wouldn't work.
I pretty much have given up. I returned the card mentioned above. I even bought and tried another wifi card without success. My experience has been:
Intel wifi 4965 miniPCIe: Works great, but anything past Linux kernel 2.6.27 (I think it was) will not boot with the card in the computer and with the wifi switched on.
Intel wifi 5100 miniPCIe: The wifi switch never appeared to detect it. Linux detected it and installed the drivers for it, but the "wifi on" light never turned on, and Linux couldn't use it because it didn't think it was on. I gave up and returned it to Newegg. The problem may have been related to this, but that is for miniPCI cards, and not miniPCIe.
Intel wifi 3945 miniPCIe: It is branded as a Toshiba card, and so I thought it would work in a Toshiba laptop. I bought it cheap off of Ebay. It is neither detected by the OS or the wifi switch.
I'm not sure what I'll do now. I may buy a PCMCIA card. I may just leave Hardy on it until it dies.

Is it possible to replace the wifi card with another one?

Hi
I have a t400 with intel 5100 wifi card and now I want to install mac os on my laptop.
problem is that mac os does not detect the 5100 series of wifi card and I want to know whether it is possible to replace the current 5100 model with a older series?
Is there any certified service center in Uppsala/ Sweden to do that?
Thanks,
Solved!
Go to Solution.

Lenovo restricts the wireless cards to Lenovo branded units certified to work with the machine. This is done through a whitelist in the system BIOS. I recently disassembled the latest (version 3.14-1.06) T500/W500 BIOS and found the following whitelist table. This is raw big endian hex appended with what I found by searching the device ID's. Redundant entries are for varying vendor IDs.
86803B428680111000 Intel Corporation PRO/Wireless 5350 AGN [Echo Peak] Network Connection
86803D428680111200 Intel Corporation WiMAX/WiFi Link 5150
868036428680111000 Intel Corporation Ultimate N WiFi Link 5300
868037428680111200 Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection
868037428680161200 Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection
8C161C008C16350000 Atheros AR5007EG
EC107281EC1020E000 Realtek RTL8191SEvB (Yuck, Realtek! I'd hate to have one of these...)
86803D428680161200 8086:423D Intel Corporation WiMAX/WiFi Link 5150
8680840086801513 Intel Corporation Centrino Wireless-N 1000
Your T400 is from the same lineup and probably has the same list. Remember, you'll need to purchase a Lenovo branded unit.
Also look for a PM with additional information.

Wifi card not recognized after reboot.

I've got a Lenovo X140e and an Intel wifi card. (Intel Corporation Wireless-N 7260) that I installed myself, since the support for the Broadcom card it came with was spotty.
If I reboot my laptop, the card won't show up with either iwconfig or even lspci. If I do a cold reboot (power down entirely and start back up), it will show up just fine.
What gives?
Relevant lspci output:
01:00.0 Network controller: Intel Corporation Wireless 7260 (rev 4b)
Subsystem: Intel Corporation Wireless-N 7260
Flags: bus master, fast devsel, latency 0, IRQ 38
Memory at f1300000 (64-bit, non-prefetchable) [size=8K]
Capabilities: <access denied>
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi

When the card is recognized, rfkill lists it as unblocked; when it's not recognized, it doesn't show up at all.
I've got i3 installed; for connection management I've been sort of trying different things - netctl never works but wifi-menu has been pretty reliable. I haven't installed any special power management stuff at all - I'm not really sure how to find out what was auto-installed?
