T500 Wireless N stuck at 54.0 Mbps

Lenovo published a solution for wireless N speeds not getting beyond 54 Mbps. I've followed their instructions to the letter loading the most recent Wirelss Driver (ver. 7.4.2.134), Hotkey driver (ver. 2.01.0703) and Thinkvantage Access Connections (ver. 5.12 rev03). This T500 still can not connect faster than 54 Mbps. Using Thinkvantage Wireless Connections, menu "Manage Location Profiles", "Wireless Settings" tab, wireless mode only displays 802.11a,b,g. "N" is not even an option. Strange thing is, on a different wireless "N" router NOT running WEP 128 bit encryption like what I am running, I can connect at 130 Mpbs. Could it be Lenovo hasn't published a fix for wireless N running WEP 128 bit encryption? Any advice?

David.

You need to be running either no encryption (NOT recommended) or at least WPA2 with AES encryption to get higher connection speeds with properly 802.11n Draft 2 compliant devices, like the Intel WIFi card you probably have in your T500 .
The 802.11n Draft 2 WiFi standard does not accommodate WEP encryption, so it not something Leneovo can do anything about with a "fix".

Wireless Switch stuck on the OFF state

Hello! About 2 months ago I switched to the Windows 10 preview and would experience Internel_Power_Error, whatever not a big deal it was once every so often so it didnt bother me too much, then after Windows 10 came out I was experience this error all the time making my laptop effectivly a paper weight. I set the laptop aside since, today I pulled it out and grabbed my Windows 7 Install CD as well as the PowerSpec Driver CD. I was able to successfully go back to windows 7, but for some reason the Built-in switch to toggle Bluetooth and Wireless is stuck on the OFF (Orange/Amber) state. I have a second computer so I was able to research and transfer via USB the correct Ethernet drivers. However my laptop is still indicating that there are no connections available. My Ethernet and wireless Controller, QualComm Atheros QCA9565 802.11b/G/N WiFi Adapter:PCI\VEN_10EC&DEV_8168&SUBSYS_1944103C&REV_0CShould have driver: SP64676However when I try to install this driver it completes its install and says the driver was not installed correctly. I also have PCI Device which is missing a driver acording to the Device Manager:PCI\VEN_10EC&DEV_5227&SYBSYS_1942103C&REV_01 As well as an unknown Device:ACPI\HPQ6007 Is it possible that due to the Switch being in the OFF state these drivers are not able to install properaly? If so how do I go about disabling the Switch completly so the button has no effect on the computer whats so ever? Thank you for your time, I have looked at so many threads and tried everything I could so if anyone can point me in the right direction that would be wonderful! -Andrew

I really need some help here, I have a $900 paperweight sitting on my desk collecting dust. If anyone has any ideas no matter how crazy it is, I will try it. -Andrew

Stuck pixel on new MBP 13

I bought the new MBP 13" the day they went on sale (feb 24) and I just noticed a stuck pixel near the bottom of my screen. Does Apple usually cover something like this within the first 30 days?

Hmm, since you said that, they may be a minimum number of dead pixels acceptable until they will fix it. I believe I read that somewhere before. You won't get charged a restocking fee to return the computer, but you only had 14 days from your purchase date to return it (if you bought it directly from Apple). Looks like your past that date. You may be able to swing something by calling Apple, considering your machine is just 3 week sold.

T500 wireless connects and disconnects every few seconds

The machine has the Intel 5100 adapter in it, and runs W7 x64. There are numerous other devices using wireless in the same house, including two T61ps, which do not have this problem.
The T500 is using the latest Access Connections for W7, and the latest Intel drivers (the machine is 10 days old, and is fully updated using Lenovo System Update and Windows Update. Not much 3rd party software yet due to this and another problem with the T500.)
Every few seconds, the wireless will disconnect, then reconnect immediately. I have tried turning off power management for the wireless adapter, including telling Windows not to power it off for power savings. This occurs running on AC power, haven't tried on battery. (This is irritating enough as it is, but it makes W7's Windows Explorer keep moving things up and down in the display as the network items disappear and reappear.)

Hi Graham,
Try increasing the roaming of your wireless card from aggressive to low and power output to maximum in the power management option.
Hope it helps.

Thinkpad T500 Wireless Driver Issue in Windows 7

The subject pretty much says it all.
I've installed Windows 7 (x64) and everything is working fine with the exception of my internal wireless adapter. I've tried all the Windows 7 drivers provided and also tried the Vista drivers (x64 when applicable). Still nothing. It's (as far as I know) the Thinkpad internal wireless as opposed to any of the Intel ones.
To rule out a few things, yes I've checked to make sure it's enabled in the BIOS, and I'm certain the wireless switch is on.
Anyone have any ideas or similar fixes?
Should it help, my exact model number is: (T500) 2242-CT0

Hi and welcome to the forum!
Try this, install the Hotkey Features, do a mandatory reboot, thereafter press Fn-F5 to radio on the wireless device, once that's done install the wireless driver.
Would be a good idea to check in the BIOS if the card is enabled in there.
Let us know the outcome.

T500 Wireless troubles

Hi all,
After extensive googling and forum bashing (and obviously not finding a clear cut answer), i've decided to put this problem out there -
I have a T500 which is 2 days old, with an intel 5100 wireless card. My old laptop (a T42) can connect to the wireless network (secured) at my place. The router is a d-link DI-624 with the most recent firmware update. The T500 can't connect to the wireless network for some reason. The signal is 'very strong', and it asks me for a password. Although the password comes out as 8 digits (my password is obviously 10 digits), i read that it's just the GUI doing some tricky dicky privacy thing. It takes a little while to think, but in the end all i get is 'limited or no connectivity'.
I checked the router settings and all that. Channels, g-modes etc. etc. The log on the router says that it had registered my MAC address, but unlike for my T42, it did not allocate me an ip in the vicinity of 192.168.0.100+ (which would mean it was working).
Anyway, out of desperation i reformatted the thing so now i have a super clean windows XP home (sp 3) installation. The only drivers i have installed are the power management, wireless lan (the most up to date drivers) and ATI graphics ones. The wireless radio is 'on' (?), and everything else is exactly the same as my old laptop.
It can't be my router as my family can all connect to it, and so can I. The only quirky thing is that on my T42 (XP SP1) i can set the index key to 0. It was previously at 1, and for some reason wasn't connecting until i changed it to 0 (might just be computer fate). But, of course, the index key on the T 500 only goes from 1-4 (don't know if this matters so much).
Long story short - i don't think it's the router. It doesn't use filtering. I can see the wireless network. I can enter my password. I have no firewalls (the installation is CLEAN 100% pretty much). I have the most up-to-date driver for the wireless card (should i have a less updated driver?). I have the wireless radio 'ON' and i think i have all bases covered. (oh, and because it's clean i have NO lenovo apps)
Is the problem a hardware thing? a driver thing? or just some stupid thing i've missed. Please help i have tried pretty **bleep** hard to fix it.

can you back date the bios to the older one?

Wireless network drops out on one MBP, not the other

I have two Macbook Pros as part of a wireless network (Extreme/Express 802.11g). Lately the older of the MBPs (2.16 Core Duo) keeps losing the connection and won't recognize the network. If I restart the Airport Extreme and my modem and the MBP it will sometimes come back. Meanwhile my brand new MBP never loses the connection.
Anybody have any suggestions on where I can start looking or what I can start adjusting to eliminate this problem? Please don't hesitate to let me know if there's other info I can provide to help solve this.
Thanks in advance.

If you place the two MBPs side by side for a few hours, does the older device still lose the wireless signal while newer one remains connected?
If yes, then you may have a wireless card that is starting to act up or the internal antenna connector may be making intermittent contact. A repair shop will need to check things out.
If no, then you're likely picking up some form of wireless interference in the area where the older MBP is normally located. The usual culprits are a cordless phone (sometimes at the neighbors) and nearby wireless networks. Post back for a few suggestions on this.

Migration assistant stuck on new 15' MBP. Help!

I've been having a terrible time with the migration assistant. I have a new 15'MBP retina fully loaded. Been trying for days to transfer my old applications, etc from my older 15' MBP. I could not do it through the wifi (tried but it just died after 18 hours). So I hooked up the computers with fw800 (with thunderbolt adapter on the new computer) and that didn't work. Then I backed up my old computer using time machine and am trying to setup new one with that backup but it's been 18 hours and seems yo be stuck. The bar is at the same place it was 8 hours ago. The estimated time went up from 3+ hours to 5 hours, so I guess something is happening even though the bar hasn't moved? I have about 350gb of stuff so I get it could take a while but it's been about 18 hours. What should I do! This is driving me crazy... I need to be up and running for work tomorrow.

BT Infinity Hub stuck at 2-3 mbps and constant dis...

It first started with the Hub 2 which would constantly disconnect and run slowly from the laptop, playstation, smartTV, BT box, mobile phone a few times every hour. After the poor customer service and days of being told to 'restart the hub' etc etc an engineer was sent out and installed the Hub 3, which seemingly worked.... until a speed check, I have tested the speed every day for the past month and the download speed has never gone over 3mbps and usually sits around 2.5mbps. After weeks of being on the phone and trying to restart the Hub etc they sent a new Hub 3, which when tried to install wouldn't power up at all. The on-demand is constantly affected, and every 3 seconds the spinning triangle will come up and be like that for 10+ seconds. So back to the old Hub 3 which rang in at 2.5mbps. As BT seem so against sending an engineer I don't know what to do, I'm at my wits end with this and feel like going to Sky or Virgin as with BT I've had numerous months of no on-demand and internet at months at a time with no recompense. They keep trying to tell me that our laptop is faulty, except that I've had 3 different friends bring their laptops around and they measure 2-3 mbps, and they still are trying to say it's my laptop.

T500 Wireless radio is always off.

I have set the wireless switch on, checked the Device Manager, and done the Fn-5 thing. Nothing, it seems, will turn the radio on. I am using Windows 7 and I know that the hardware works because it worked for the first three days I had the computer. I have spent days looking for a solutions. All drivers have been checked and are up to date.
The wireless adapter installed is the Intel WiFi Link 5400 AGN. The Lenovo site suggests that I should be looking for a LAN Mini PCI Express Adapter - this seems to be missing. There is no instruction about what to do if this does not appear in the list of Network Adapters. Is this my problem - and if so, how do I correct it.? Any other suggestions, please?

Try going to the device manager and uninstall and installing the wifi card. this should solve the issue.

Wireless keyboard stucks on fn function key

Hello Guys,
i bought a brand-new Apple Wireless Keyboard and its working very smoothly, but i have some problems with the fn + function keys Combo. I'm using Mac OS X 10.7.3 and when i press FN + F11 (for example, but it's concerning all function keys), it should show me the Desktop. But unfortunately only Volume gets louder till i press it again. I have this problem only the first time pressing the keys. For all following combos its working till i dont press any key for some seconds.
Any others having this problem too?
Greetings and thanks for help,
Patrick

I returned the Keyboard to the Reseller and got a new one: it works perfect now! Can be closed.

HP550 wireless button Stuck on red?

Hi
Hope someone can help
Got an old HP550 notebook it's been fine with nothing going wrong till a couple of days ago.
Was installing different flavours of Linux on the laptop, worked fine till I installed a more recent version of Linux Mint.
Since then the wireless hardware button won't change from red.
I've reinstalled my old copy of XP and updated it to latest SP and made sure the propper XP drivers are installed.
The button is still red.
During boot the button is blue then once the OS starts it changes to red.
Diagnostics sat the card is fine, it is just that I cant seem to toggle the hardware status.
Ive reset the card and the 2 wireless arial cables no change.
Is the wireless card or the wiring on the way out??
any help hint and tips welcomed!
