X201 wireless N problem

Thinkpad x201-3294cto
wireless adapter--realtek 802.11b/g/n wireless adapter II
Laptop only runs at speed of 54mbps when connected to Wireless N 300mbps Access Point. Is there a problem with Realtek Adapters? Is there something I should be doing to operate at speed of 300mbps?
Solved!
Go to Solution.

OK--- problem solved. Found out that to run wireless N at 300mbps I had to set security on my Access Point to
WPA2 Personal-AES. I think that is going to be the future standard. Thanks for the inputs.

X201 Wireless switch Hardware problem - PLEASE HELP

Hello everyone,
I have been a regular reader of this wonderful forum and have also participated on a few questions. I have an x201 which I bought from UK 6months back.
After a smooth sail for many months and just when I thought life was going good, I have a wireless switch problem that pops up out of nowhere. I never use hardware switch and had to do it only last week because of checking for my internet connection problems.
Only once in my entire experience with this laptop that I put it off, now it has become so sensitive that even shaking the laptop while typing turns off the laptop. On reading about this problem I found out that it is quite a common problem with x-series and has many users affected from it. After confidently calling the customer support they ask me to pay 200euros just to "TAKE A LOOK AT THE PROBLEM"????. Apart from at least acknowledging the persistent problem across all the models they end up asking me to pay for everything and cannot tell me how much it will cost me or even tell me how long it will take to replace this.
Is there any other way to do this? The support told me that the only other way to repair this will be to buy the Base switch myself and then replace it. I am a biologist doing my PhD and have no knowledge of all these. Apart from all the appluad this laptop got from my colleagues, now they all think this is a joke by Lenovo to be charging for something that is entirely their mistake.
Can anyone point to a solution please and help me. I was really looking to buying an ultrabook next year but looks like replacing a switch is going to cost me 1/4th of what one would be for an entire laptop.
PLEASE HELP

Hi
I am experiencing wireless connection problem on 4s after ios 8.1 upgrade. The wireless icon appears showing that it's connected but webpages do not load. I have checked my internet connection with other devices and seems to be alright. what to do?
I have tried reseting the network settings and forgetting my wireless connection and re-connecting to it. I even backed up my phone on itunes and restored it, factory reseted it. Nothing seems to work.
Also after my upgrade to ios 8.1 my personal hotspot option under cellular data has disappeared.
Would you please help me out? I would really appreciate it.

Hi..
Restart your router then restart the iPhone to test.

Wireless connectivity problems using IOS 6.0.2?

After installing IOS 6.0.2 on my iPhone 5 I can no longer connect to known wireless sites. I've been through troubleshooting with both Apple and my ISP and no luck. I'm thinking there's wireless connectivity problems with this latest update (my iPad 3 is still running 6.0.1 and is fine on my wireless network). Are others having this issue as well?

I am not guaranteeing this fix , but it worked for me , so far. I have an iphone 5 and it had ios 6.0.1 . Worked fine. Upgraded to 6.0.2 and it wouldn't connect with home router most of the time. My son in law an IT guy for the Government came up with a solution. The problem seemed most likely with routers that are bought and not configured and retain the original factory settings. Therefore my phone considers my home network a generic one and I have to manually connect to it. To distinguish the network we did the following.
1) went to settings on my iphone
2) choose "my home network" by pushing the arrow on the right
3) This brought up the network info page. (it says "forget this network " at the top)
4)DHCP will probably be highlighted.
5) touch "static"
6) This will bring up the manual settings
7) We entered the following.
For Ip Address 192.168.1.15
Subnet Mask 255.255.255.0
Router 192.168.1.1
DNS 4.2.2.1,4.2.2.2,8.8.8.8
Leave the HTTP Proxy to off
This will assign a static Ip address not a dynamic one and should work.
If it doesn't , go back to step 3 and select DHCP and return to the dynamic state .

Fix for Airport Wireless Connection Problem stating Self-Assigned IP and not wanting to connect in Lion OSX.

Fix for Airport Wireless Connection Problem stating Self-Assigned IP and not wanting to connect in Lion OSX.
Bought my girlfriend the newest Macbook Pro 13" and began experiencing problems with my wifi the moment we got home. Her Macbook would not connect to our home Wi-Fi while my old Macbook Late 2008 running Snow Leopard connected without a problem. Airport would say that it had a Self-Assigned IP address (168.x.x.x). Did not realize it was a Lion problem until after using her Macbook Pro and becoming jealous of the new OSX, I upgraded. Soon after I was unable to go online. Luckily I had my iPad 2 and I began to scoure the net for help. Ran into allot of suggestions but it was not until I tried the following all together was I able to share the good new, from my Macbook. Hope this works:
First go to Preferences > Network and click on the cog next to the + and - on the sidebar and click Set Service Order
     - Move Wi-Fi to the top and click ok.
     - Set location to Automatic
     - Click Apply
     - Click Advanced
     - Click the "-" on the selected Wi-Fi router you wish to connect to
     - Click Apply
     - Click Lock to Prevent Further Changes
Go to your Mac's harddrive, (Macintosh)
     - Go to Library > Preferences > SystemConfiguration >
     - Delete "com.apple.airport.preferences.plist" file
Turn off your computer
     - push and hold Option+Command+R+P
     - turn on computer
     - when the grey screen turns on you will hear the OS X "ON" sound (for lack of a proper term) and it will momentarily restart.
     - you will once again hear the "ON" sound, let go of all keys.
     - this resets your PRAM
Go to Preferences > Network > Advanced > + sign
     - click Choose a Network
     - Select your network and enter password
Viola!!! I tried this on my Macbook Late 2008 and my girlfriends new Macbook Pro 2010

     No you are clearly mistaken. The Self-Assigned IP address problem exists on many Macbook Pro models, including the current model, which I mentioned as being the original computer with the problem. While my 2008 Macbook is older it was working perfectly on Snow Leopard and didn't suffer issues until switching to Lion. So clearly the problem exists on the operating system and not so much the hardware.
     I called Apple Support and they had no fix for the problem and told me that this would hopefully be addressed in a subsequent update. It wasn't until I came accross the answer after trying many different methods that I got both of the Macbooks to connect to my router. Otherwise I wouldn't or could not have been surfing the internet for the last 4 months.
Cheers.

Macbook Pro Wireless Connection Problems

I bought my 13 inch macbook pro 1 week ago and I've had wireless connection problems from day 2 (I think after the updates).
Problems include:
- Safari cannot connect to the internet for 5~10 minutes after I turn it on, whether it be from sleep mode or completely off or restart (the fastest connection I got after turning it on was about 40 seconds)
- Loading takes ridiculously long and eventually Safari cannot find the server
- Airport signal (on the top right hand corner) is always full when it is not working
- Sometimes internet works but it is ridiculously slow
However, when the wireless connection stabilizes, Airport Signal is 2~3 bars full and internet works SOOO well and I love it so much when it does. But the problem is that it stabilizes like 30 minutes to never after I turn it on and it makes me so mad I want to explode this piece of crap in the microwave.
So I've called apple support, and they made me try four things:
1. Reset modem, router, and computer
2. Delete caches, reset Safari
3. Putting Airport first on the Service Order and resetting DHCP Lease
4. Connecting with Ethernet Cable then resetting the computer
None of these worked, and I'm suspecting that the cause of the problem is the hardware (not the aluminum body that's just bs) because my router and modem are working fine (my other samsung laptop is working perfectly). I don't think the problem lies in my network settings either because I did exactly what the Apple technicians told me to do. So after Appleguy made me try all 4 of those diagnostics, he told me to contact my router company NETGEAR because he thinks nothing is wrong with the mac hardware, so I did. The NETGEAR lady told me if one laptop is working and another isn't, there is nothing wrong with the router. So if nothing is wrong with my hardware, software, router, modem, ISP... Why do I have wireless issues????!?!?!?!?!?!?!?!?!?!
I'm going to return this <edited by host> or get another one with my warranty

Same thing here.
I've got a Macbook Pro 15" bought 6 weeks ago, airport express bought about a year ago. All updated with latest software/firmware, etc. Problems include:
-Sometimes when i pull down the network list, my network isn't even there, yet i'm still connected to it. My airport is appx 10 feet away in an open area.
-usually after opening safari or firefox for the first time upon sleep, restart, or just opening the program after i had quit it, it is miserably slow. it takes about 2 minutes for pages like msn.com to load. finally when they do, its faster than you can imagine. that lasts for about a minute. then its slow again.
-when logged into ichat and i send messages, i would sometimes get a "connection timeout" message. my buddy would end up getting the message about 5 minutes later.
My iphone and dell laptop work fine. i haven't tried running parallels, but if bootcamp works, so should prlls.
I've reset the modem about 20 times. i've reset the airport about 20 times. i even re-installed my OS on the mac and nothing has done it.
Weird thing is that i've had my mac for 6 weeks, and this problem surfaced only 3 days ago.
Clearly its not an issue of any of our ISP's. Due to the fact that this only started for me 3 dyas ago, i'm hopeful that its only a software problem and not something else. Hopefully apple will a) ADMIT THEY HAVE A PROBLEM HERE and b) FIX IT.

A Fix for Wireless Connection Problems

I’ve been struggling with connection problems for a week. Thankfully, I found a fix. Your mileage may vary, but this may be your answer:
Fix for Wireless Connection Problems on MacBook Pro

Yeah BR, please tell me what your cure is. I have the same setup as you, Vista with the same wireless card you have. Cannot stay connected to the internet. Have spent hours on the phone with tech support and they can't fix it. I hate this f....ing computer, will never buy another one. Please let me know what you did. Once I get it running right I'm selling it and will buy a cheap Dell, never have any problems with them. I have keyboard problems, capital letter problems, connection problems, and download can take 1 to 2 days. Pure BS!!!!!!!!!!!!!!!!!

Wireless printing problem

I have wireless printing issues. Here is the setup. I have a desktop pc (windows xp) with a wireless router. I had an HP printer connected to the pc and had a pc laptop and mac laptop with wireless cards for internet access and sharing the printer with the desktop pc. All was going well. I bought a new imac intel core duo and got a canon ip4200 for free. I replaced the HP printer with the canon which is now connnected via USB to the desktop pc. The pc desktop prints fine. The new imac connects to the internet wirelessly, no problem, but will not print correctly. At first, after selecting the canon printer on the imac it would print a document in a very small font in the upper left corner of the paper. After downloading new drivers, tech support, etc it will not work at all. Canon says that the ip4200 is not a "network printer". Is there any way to make this work without changing my whole setup? I am a computer novice!

I had similar problems setting up a printer on my iMac that was hung off a windows PC. I ran 'Bonjour' on the PC and set the iMac up again and all worked fine after that.
Worth a try.

Broadband/internet and wireless connection problem...

Towards the end of 2101 I received an email informing me that BT would be upgrading my local line and I could expect a much improved service. Whether this 'upgrade' has been the cause of my problems or is merely coincidental I cannot say. Prior to my experience since this time I could count lost broadband in hours per year (I never had internet or wireless connection problems).
Since the end of 2010 I now regularly lose my broadband completely every six to eight weeks. 'Home Hub cannot connect to broadband.' There is a worsening loss of speed? over a period of two to four days at the end of which I need to phone BT three/four/five, etc. times until they manage to locate the problem and fix it. It is always some problem they find on the line or with their equipment.
I always mention that this is an ongoing problem. Never do they take any action to escalate the issue.
This week things have become considerably worse.
I have started to lose my internet connection now. 'Safari cannot connect to the internet'.
There are now two issues which arise concurrently.
I phoned BT, finally the operative in India (through a very poor BT wireless phone connection) changed the channel of my router for me. He mentioned something about changing the address and password. This seriously exacerbated the situation. My password is not recognised now when I am asked to reconnect by selecting a network.
The next occasion on which I lost my INTERNET connection and tried to reconnect I got the message 'Airport has the self-assigned IP address (...........) and is unable to connect to the internet.
I phoned BT to report this and was told that this indicated an adapter problem and the problem was now out of BT's hands. I Should contact Apple.
I did so. Apple said I should contact BT to change channels. I explained this had caused the problem and they were now refusing to assist me. Apple tried everything that they could think of to resolve the issue (despite not being required to do so). Eventually the only suggestion they could make as BT had refused to help was to reinstall my operating system. Extremely drastic. But I can now connect wirelessly again.
Service is still intermittent requiring constant restarts to regain connections.
BT's response to a formal complaint was more of the usual banal questions, the usual tests, the usual promises of 'something would be done'.
Their systems are not set up to make any sort of accurate diagnosis of customers' issues. They seem to have a set number of 'fixes' into which they try to fit all problems - one would assume simply to save costs - their cost saving exercises are now costing me money.
That's all for starters.
Any suggestions?
Solved!

I have a similar problem, since BT "upgraded my broardband" my home hub looses internet connection at least twice a day and I have to power reset it. the broadband shows as connected but the internet connection is lost, if I try reconnecting it fails and only a power resetr will work. I have a temp solution by fitting a time switch to the mains adaptor and reseting it at 0200 each day. but before the upgrade the home hub had worked for years and no problems. i have also replaced the origonal home hub 1 with a home hub 2 to see if that improves the situation.
welcome to the forum
This subject has been marked as solved by the originator and you will get more response if you start your own subject rather than continue here.
if you start your own subject just cut and paste your post and then in order to help please can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester (MAC users may have problems) http://speedtester.bt.com and post the results .
are you connected directly to the NTE5 master or test socket or to somewhere else? Do you have any phone extension sockets in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem

C4580 Wireless Printing Problem

We purchased a C4580 a few months ago and successfully installed it into our home network. We eventually had to replace the printer cartridges and went with the high-capacity HP cartridges - then we noticed a problem. Every time we print out a test page on the printer, it is perfect; however, every time we submit a print job wirelessly the page is a mess! The wireless print jobs are full of gaps, incompletely printed lines, and doubly printed letters. AARRGGHH!!! I am thinking of loading an SD card with a print job, inserting it into the printer and seeing if that will work. I have updated all software and have had no luck so far in overcoming this wireless print problem - any suggestions?

I was going to lead you to this page to download and install the Full Feature driver. I also noticed that there are quite a few updates for the software and printer on the same page.
I still think you should install the full featured driver, but if it persists, try some of the updates?

T400 & X201 wireless problem

Hello,
I have 2 Lenovo Laptops (a T400 and a X201, both with Vista) that can't get internet connection over wireless.
I recently installed internet on my new flat.
The router I'm using is a Netgear DGl1000.
I have another computer that can connect to the router via wireless without any problems
I have both an android phone and an iphone that can also connect.
I can connect both Lenovo laptops if I use an ethernet cable.
When I try to connect via wireless, I can connect to the network, I can ping the router IP address and the Windows tray icon indicates that I am connected to the internet, but I'm not. I can't ping anything else.
Anyone has any idea about what might be happening?
Thanks,
Joao

hey joaoleal,
just to be certain .. when network cable is connected, you can get connected to the internet but if using wireless no connection at all even though both units detects the SSID being broadcasted by your NetGear?
could you try this, uninstall the current wireless driver then let windows install its generic driver.
on your netgear, reset the connection and set the SSID to broadcast without any security.
remove any wifi profile your two laptops might have stored and try again

X201 Wireless Problem

For the last couple of weeks, my laptop has exhibited kind of a strange problem. The wireless will sometimes stop working. The wireless adapter isn't disabled, but no networks can be found. Additionally, when this happens, the computer can't be but into sleep mode. The screen goes black, but it never gets to sleep or hibernate. Any suggestions on what might be going on?

I recommend first a view into the event manager (Controlpanel - Administrative Tools - Eventmanager - (in Win7) Windows events - System
Do you find there hints (errors) concerning WLan (driver) or/and powermanagement?
I also recommend to update

X201 Wireless Card not detectable (Centrino Ultimate-N 6300 AGN) (Windows 7 64 bit)

Hey!
I have a slight problem here.
We have 5 machines that got shipped with Windows 7 32 bit versions for two weeks ago, I tested all of them to make sure nothing was defect or such things but everything was fine (The wireless network card was clearly visible in device manager).
For two days ago, we recived recovery discs to upgrade these machines to 64 bit versions.
After installing it on 2 computers that was previously 32 bit versions, I am not able to detect the wireless network card anymore.
I have used System Update to try and find it but to no avail.
The card itself is not even detected by Device Manager (No unkown device or anything either, it have simply dissapeared).
I do know the card is present there so I downloaded two different drivers (1 from Lenovo homepage and another one from a driver update tool) (13.1.1.1 and 13.2.0.30).
I made a manual search and installed the drivers and the card itself by using "Add Legacy hardware" in device manager and picked the card.
It is now detectable in Device Manager but with following error code:
"The device is not working properly because Windows cannot load the drivers required for this device (Code 31).
I have tested both versions but same error code persists, System Update won't help either since it says that there are no new updates for this machine (same thing with Windows Update).
The card was functioning properly in 32 bit version but decided to crap out when upgrading to 64 bit, have there been frequent problems regarding wireless networking with 64 bit?

We have the same problem with 6 new X201 machines preloaded with Win 7 32bit
After reloading the X201 with the Win 7 64bit recovery media the wireless network card disappears.
You learn to disassemble the laptop quickly to get to the CMOS battery because thats the olution I found
Disconnect the CMOS battery to reset BIOS settings completely and the network card appears in windows again.
Even when we tried the same recovery media on a T500 to test it, the same happened. The CMOS battery solution got the WLAN card working again.
I have reported this to Lenovo but havent heard from them yet.

Wireless printing problem with HP Envy all-in-one 110 when running Mac OS 10.7

I just bought the HP Envy all-in-one 110. I have a Macbook Air running IS 10.7. I managed to install the software correctly and the wirless network light is showing on the printer. I ran a test page from the printer and all the settings say they are "enabled." But I still can't get the printer to print over the wireless network. When I plugged in a USB cable, I managed to get it to print. I have a wireless router running over the Sonic.net DSL network. Network strength is good. I've switched off and restarted all equipment several times but still no results. Help!

Hi,
I believe the router may not support Multicasting, a network protocol used for Apple's Bonjour service to operate as it should.
Will be helpful to know the exact router brand and model.
As a workaroung, you may try setting the printer by using standard IP, it should allow you to print, however the router issue (more likely) have to be handled first to allow the full software functionality including scanning.
Follow the steps below to set an IP print queue, it will also help to better understand the cause for the problem:
Enter System Preferences > Print & Scan.
Click the plus sign.
Click the IP icon.
Select the HP Jetdirect Socket protocol.
Enter the printer IP address into the Address field
Now try printing using the newly created print queue, listed as the printer IP address.

Sorry you are having problems with printing from the internet. I have a few more questions to ask you before I can be of much assistance.
What web-browser are you using?
Do you have any problems printing from Word or other non-internet documents?
What did you do to fix your computer (system restore, clean install of the OS, etc)?
Have you tried an alternate web-browser?
Make sure to install all of your Microsoft updates to see if that helps. Otherwise, answer those questions for me please and I will be happy to help.
Don't forgot to say thanks by giving "Kudos" if I helped solve your problem.
