I hope the replacement card fixes the problem. Over the years I have had just one bad network card -- and it drove me nuts tracking down that it was, indeed, a failed card.

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!!!

Lenovo M90Z Not Detect WIFI Adapter

Dear Forum
I have problem with my Lenovo Thinkcentre M90Z.
Recently, the Wifi Card was not detect any wifi signal available in the near site.
I trying to uninstall the driver to solve the problem.
But unfortunatelly, after unisntall the Wifi adapter dissapear from the network adapter list.
I have try re-isntall the driver but no result.
Also try to re-attach the WIFI card to the slot, but it still not recognized by the OS.
Any solution for this problem?
Here the screen capture of the device manager and the network adapter list :

Have you tried Safe mode with Networking? Check if the adapter is being detected in Safe mode. You can reboot in Safe Mode by pressing the 'F8' key repeatedly as soon as you turn on the computer. If you're using Windows 8, refer to this link for how to start your system in Safe Mode:
http://windows.microsoft.com/en-us/windows-8/windows-startup-settings-including-safe-mode
If the adaptor is being detected in Safe Mode, try updating the drivers and uninstalling any new hardware or software that you might have installed recently. If it still doesn't work, try doing a system restore back to the point when the adaptor was detected.
If the adaptor is still not getting detected even in Safe Mode, it's probably a faulty adaptor, or it might not be connected properly on the mother board. You might have to open the system to check the connections. Keep in mind that opening the system up might void your warranty if the system is still in warranty.

do not have access to the net.how can i fix the problem??i must install driver?????where can i find linux drivers for my laptop model? because i searched lenovo website and it does not have drivers for linux for B590

Do this in terminal while you have connection via lan cable:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43
The last option is using ndiswrapper with this windows driver

HP Pavilion 5500 not detecting any 5G Networks (Jan 2015) [Ralink RT5390R]

I have resently been having trouble with slow internet. My Desktop PC has stopped working with my wired router and refuses to find my 5G network.
My connection was getting average scores of 40 Mbps but now im only getting 3-5 Mbps while my phone and laptops are getting 35-40 Mbps. My Desktop is the only thing struggling with the internet and it has a direct ethernet link.
I resently had a Service Provider technition here to see if it was my router but it is only my pc having issues.
I have looked around this site for hours looking to find a solution and have tried almost everything but posting my issue directly. My internet was working fine till about 2 weeks ago from 01/04/2015 but dropped speed severly. Now when i try to connect to my router, it appers to only work on 2.4 Ghz, the tech said that it shouldnt matter what network it can see aslong as it is directly connected but its no better than my android.

Hi Alex,
Please post the HP product number for your PC. How to Find the HP Model Number and the HP Product Number or let HP automatically find your PC model number and HP network attached printers. This will allow others to review your issue, make suggestions and review your responses. This is usually the best way to get assistance.
I very much doubt that you have a driver issue since your issue is recent. However, review the recent updates made to your PC both from Microsoft and HP. Move your PC close to the wireless router for a test to see if you have an obstruction issue.
Download Vistumbler to one of your laptops and your PC to verify that your wireless router has both 2.4 ghz and 5.0 ghz service.
HP may have updated drivers for your PC but since you issue is recent it might very well be that the hardware adapter has failed. Running Windows diagnostics and HP diagnostics including UEFI diagnostics might discover the problem.

Airport dual enet snow and usb 802.11g wireless usb adapter

Can I use a wireless 802.11g adapter with my imac (iLamp)to connect to my snow base station, or bo I need ans xxx.11g /b adapter?

Sorry - I missed that from the title of your message.
The answer to that question is no - an exclusively 802.11g USB wireless adapter will not be able to connect to a Snow Base Station. I'd be surprised if this was ever an issue - I don't know of any exclusively 802.11g USB wireless adapters that work with Macs.
I suggest you avoid use of USB wireless adapters with Macs. Yes some people have used them successfully, but still more people have nothing but grief with these devices. Very, very few USB wireless adapters have any MacOS driver support in the first place.

Slow wifi with Ralink rt3290 network adapter

I formated my laptop and installed win 7 x64 once again.My wifi was fine before but now I have installed all the drivers from HP support and my wifi speed is very slow although other laptops in my house have normal speed (about 10 times faster).I have a Ralink rt3290 adapter with driver version 5.0.45.0, I have tried to uninstall and install all the possible driver versions with no success.I tried all the forums I could find and did DNS flushing and such, the router is configured fine and is not too far or too close to my laptop.If I connect with ethernet cable my speed gets to about 80mps, when on wifi I get 5mps and on the other laptop I get 40mps.I really don't know what to do and I don't think that the adapter itself is broken.Can someone please help me?? Thank you,John

Yes there are older ones, but it sure seems odd that the older you go back the better they work... I am going to give you a link with revision histories of the drivers. Try any of them you want...I would start with 5.0.5.0 http://h20565.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=5229456&swItemId=ob_113862_1&swEnvOid=4059#tab-history I would also check to make sure the wireless card antennas are securely fastened to the wireless card. There are rare circumstances where one of the antennas are not securely fastened to the card during assembly and that causes all kinds of issues, needless to say.

Identify 802.1x support wireless adapter

hi guys:
IS there any good ways to detect if the client's computer support 802.1x(OS or adapter)?We would rather not check each client's computer one by one.Thaks for help.
regards

No, not really. You'll just get a string of "Cannot Associate" type messages.
The other danger there is things like .... Intel had a series of drivers for the BG2200 that would cause MIC errors .... if the AP sees two MIC errors in sixty seconds, by default, by spec, it will shut down for a while. The radio goes off-air .... everything drops.
There is a timer / setting / parameter you can tweak to keep that from happening (I don't remember which one), but thoses are the kinds of risks you run when you don't / can't control the client specification.
Good Luck
Scott
