Satellite U920T - dropping wireless connection

My Satellite U920T seems to sporadically drop its wireless connection and reverts to 'limited' connection which provides no internet access. This is the case on both my home and work wireless networks.
Can anyone offer any advice please?
Thank you

Do you use original preinstalled OS that you got with your notebook?
Is latest WLAN driver installed?
Is the situation the same when you use it with battery or AC power supply?
For testing purposes have you tried to restart your home router and check if the same will happen again?

E3200 - Dropping wireless connection on the Mac

Pros: Gig Eth switch, no front-facing indicator lights, familiar web interface...
Cons: WiFi Protected Setup doesn't belong. Continually drops wireless connections to my Mac Book Pro (but none of my other devices), which worked just fine on the E3000 this unit replaced and works perfectly on other WiFi networks. REALLY SLOW web interface - average time to move from one page to the next is something north of 9 seconds. Again, never a problem with the E3000 that this unit replaced. Price? I wouldn't complain about price if this thing actually worked as expected.
Other Thoughts: I'm hoping it's just a flaky/defective unit and not indicative of the overall quality of newer Linksys products. Firmware isn't the issue - it's running the latest one from Linksys' site.

First of all please verify that you have got a 802.11n card in your computer. New generation routers (i.e. E3200) speaks an entirely different language with 802.11g cards, so while those adapters can work with the E3200, but they are not optimized to provide good performance. It is like having to translate from one language to another in real time when going from N to G.
Well, there are few things you should keep in mind with regards to N routers:
1) For the best possible speeds, you need to be using WPA2-AES as your security mode. Any other security mode will see your speed/range capped.
Any G devices in your wireless network will tend to hamper the performance of your overall network.
Ensure that your router is running the latest firmware from homesupport.cisco.com The new firmware includes performance enhancements and fixes.
The router by default uses a channel setting of auto, which means that it would keep switching channels depending on the interference. I’d recommend you set it to a fixed channel. Usually, 1, 3, 6 and 9 give you the best performance depending on your environment of course. I’d suggest you try different channels, observing each for a while, to see which gives you the best performance. You can follow the link here on how to change channels.

WRT54G keeps dropping wireless connections

Wired connection to the router works fine. But it drops all the wireless devices (PC, phone, tablet) multiple times each day, sometimes only 30-60 minutes after reconnecting. Power cycling the router "fixes" the router and allows reconnection. There are 2 topics in the FAQ section that looked helpful:
Getting poor or no signal from a wireless router
Top causes of dropping wireless connection on a Linksys router
but clicking on those does not bring up anything. Anyone know where to find those 2 FAQs? Any other ideas for what might be causing this?

Hi. You may need to do firmware upgrade on your router as is the case these days for legacy routers. What is the hardware version by the way? You can find it at the bottom of the router right after the tiny print of the model. Access homesupport.cisco.com and search for the model. When you get the router's page click downloads below support sections and from there you have to select the hardware version, once you do that you will see the firmware version for the said hardware version. Usually it is a bin file when you save it and you can open that one on the router's page. Once you access your router's page go to Administration and click Firmware Upgrade and select the file you downloaded from the website. Make sure that you do this upgrade with a computer plugged-in to the router. When upgrade is done, you do a 30-second reset and unplug/replug the router also for 30 seconds. You may refer to this link http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&vw=1&articleid=4030.
As for the link for Getting poor or no signal from a wireless router, I found this one from Cisco's public kb site but not able to for the other one but I believe they are related.

Try to change channels as well on your router: you can try 1,3,6,9. Make sure the router is placed at least 3 feet above ground and check the antenna as well if it is still okay.

WRT330N Dropping Wireless Connections

I have a WRT330N which I have been using for a while with a couple of wired connections and 3 wireless connections.
It has been working great for months, but has suddenly started dropping wireless connections. I basically haven't touch the thing since I set it up and it has worked flawlessly.
Any idea why it would suddenly start behaving this way? Nothing else about the environment has changed either.
Could it be dying?
BTW, it will drop connections with a system literally sitting right next to it.. so distance isn't an issue.

Try to upgrade the firmware of the router .
And also do not use any electronic devices in the range of router .

WRK54G dropping wireless connections

Hi,
I have a WRK54 firmware Version 1.56.01
It keeps dropping wireless connections and can't get back on, requires restarting (power) the router to allow wireless working again.
I have set the MTU to 1300
Doesn't allow me to update the firmware, error "Upgrade action is not finish!! Upgrade file pattern error."
Using Windows XP SP2
Any ideas?

Are you trying to Upgrade the firmware on your Router from your Wireless Computer? If yes, then you can Hardwired your computer to the Router using an Ethernet Cable and then try to upgrade the firmware of your Router....
If still you are Unable to upgrade the firmware on your Router, then you need to Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable..... Now you can try to upgrade the firmware on your Router.

Satellite U940 PSU6VA - Wireless connectivity issues

_*My specifications:*_
*Model:* Toshiba Ultrabook (Satellite U940 PSU6VA-00S002)
*Operating System:* Windows 8.1 x64 (upgraded from Windows 8 x64)
*Wireless adapter:* Intel(R) Centrino(R) Wireless-N 2200
*Wireless adapter driver version:* 15.10.0.12 (which is the latest for my device)
I have had this Ultrabook since February 2013, and throughout that period I have always had wireless connectivity issues, even after performing a factory reset. My wireless icon fluctuates between three states:
* Internet access
* Limited (in which case I cannot connect to the internet or any device on the network)
* Not connected - connections are available (and if I try to make it connect to the network, it will fail)
Sometimes my computer would instantly reach the "Internet access" state upon startup, and would remain in that state. Other times, it would be "Limited" for several minutes after starting up my computer before it finally connected, and even then the connection would drop out every now and then. At the worst, it would remain either "Limited" or "Not connected" indefinitely, no matter how many times I reset my wireless adapter or restarted my computer.
Until recently, I had always thought that these issues occurred randomly. However, I recently noticed that I always have a perfect connection whenever there are no other computers connected wirelessly to my home router, and I always experience issues of varying degrees when there is at least one other computer (or even a smartphone) connected wirelessly to the router. If there is another computer connected to the router via an Ethernet cable, this does not cause any problems; it is only wireless connections that interfere with my computer.
It is only this computer that has these problems; the other computers in my house never experience these issues, no matter how many computers are online. Also, my computer does not only experience these issues with my home router; it has the same issues on my university's wireless network.
My question is, how can I fix this? Is this a known bug, or is my wireless adapter defective? I know I can connect using an Ethernet cable where possible (I never have problems with Ethernet connections), but this is not always possible at university.

I just checked the page you linked to, but it recommends that laptop users obtain their drivers from their OEM rather than from Intel.
I had already checked for driver updates through both Toshiba Service Station and Device Manager (and checked both again just now). Toshiba Service Station tells me that there are no updates available, and Device Manager tells me that "the driver software for your device is up to date".
Should I update to Intel's latest driver anyway? If so, should I also install the Windows 8.1 version of "Intel PROSet/Wireless Wifi Software"?

I have found the WLAN channel setting in Device Manager and I will test it when I get the chance. But how do I change the WLAN standard?

Time Machine Causes MacBook to Drop Wireless Connection

Recently I started having tons of problems with my wireless connections (dropping after a few minutes, unable to reestablish)
The fix was to turn off Time Machine.
Help! How can I use time machine on my computer without it causing me to lose my wireless connections!
This affects my computer no matter what network I am on. As soon as Time Machine starts the backup I lose the connection to the wireless router.

Satellite L500 - Lost wireless connection

My Satellite L500 recently lost wireless connection. I looked up the Realtek wireless device in Device Manager, and it says the device is working properly. I have tried using "ping 192.168.1.1" to reach the router, and I get "Transmit error - general failure".
Any ideas?

Hi buddy,
And now does Windows recognize some WLAN networks in range? Your posting lost wireless connection is not very useful
You should try a WLAN driver update that you can download on official Toshiba page:
http://aps2.toshiba-tro.de/wlan/
If you still cannot find or connect to WLAN networks disable the WLAN power saving mode in Windows power profiles. You have to set it to maximum performance.

T41 dropping wireless connection

I've had nothing but trouble with my T41 wireless connection.The model number is 2374-3HU.
With Windows XP installed, my home wireless connection (which has excellent strength) would drop intermittently. The network would not be found and I would pull my hair out over this. I wiped out XP and installed Windows 7, hoping the problem would go away. No such luck.
The first time I set it up, the network was found and ever since then it comes and goes but I am never able to connect to it. I have a Toshiba connected to the same network and have never had a problem with it.
Are there any firmware updates that can be applied to resolve this very frustrating problem?

Hi itmanager8815,
Unless i'm wrong your computer got the Intel 2100 3B wireless adapter?
If that's the case i would only recommend to replace the mini PCI wireless adapter since i had some really bad experience with those adapters as well as some other old Intel wireless adapter in the past.
I would say that the 2100 3B mini PCI adapter is basically useless. At the time when i had a Thinkpad T40, T41, T42 and T43 i replaced the Intel wireless mini PCI adapter with the Thinkpad Wireless (Atheros) and it worked a lot better. I also had a lot of disconnect issues with the 2100 3B and 2200bg. The newer Intel wireless adapter like 5300 and 6200 i find to work great though.
I don't know any solution to fix the problem with the 2100 3B since i tried in the past without success.

Macbook keeps dropping wireless connection

Hi
this is my first post so be gentle with me LOL
I have had many issues with BT over the last 8 months, mostly due to the speed I had in my area (was 0.45MB when wired at one point), but I recently started to have an issue with the laptops in the house.
I have 2 teenagers and luckily for them we all have Macbooks as I have given them my old ones when I have upgraded I am using a macbook pro (less than a year old & wireless N) and my eldest boy is using a Macbook (about 6 years old with wireless G) you might see where I'm going here....
the problem is the older macbook keeps losing connection on the wireless, I have called and spoken to the 1st line support guys in India but it's a bit of luck if you can understand them let alone find someone who knows what they are doing. As I work in IT I completely understand and normally ask them to read my notes before advising me especially as I had so many issues last year when I was given a number to get through to the priority care team LOL , so far I have tried the following:
moving the Hub 3 to several locations around the house
reinstalling snow leopard
using a wireless dongle
I live in the middle of nowhere so there are no other houses around which have a hub3 sp none can be affecting me and I've checked this by using programs like inSIDDer.
Finally I thought I'd take it to work to see if I could get the model number of the wireless card and order a new one and guess what it works fine!! So I thought I'd check at a friends and again it works fine for the whole time I'm there.
Brought it home and it won't stay connected GRRRAAA!!!!!!!
I've heard that the hub3 doesn't like having a wireless N & and wireless G laptops on the connecting at the same time is this correct? Has anyone else heard of this?
finnally I do have windows machines in the house and none of them (2 laptops and a desktop which is wired) are having an issue but the Sony TV which is wired directly in to the hub will also drop connection randomly between 8 PM and 10 PM every day so I'm leaning towards the hub being a rubbish router instead of the problem lying with my Macbook

There is some help with wireless connection on this page.

ATV keeps dropping wireless connection, loses connection information...

Hello.
I'm running the latest OS for ATV. Every other day I'm noticing, when I flip over to my ATV, that's it's lost its connection to my wireless network. I realize this may be the result of interference, but when the ATV drops its connection, does it also "forget" network connection information? I mean, I can understand dropping a connection because of interference, but shouldn't it remember the connection information, so when the connection is available again, it just reconnects?
I never had this issue with OS 2.x and only started with the OS 3.x upgrade.
I don't have the option to hardwire the ATV.
Regards,
Kristin.

Since I went to 5ghz wireless N on Apple Extreme device none of my 4 ATVs have lost connection. That was 18 months ago. Before then I too experienced frequent and frustrating loss of signal problems. I picked up a used Apple Extreme on Amazon for about $100 and set it up in the basement, near the center of the house. It communicates well through 2 floors and multiple walls.

X100e regularly dropping wireless connection

Had my new x100e (Windows 7 Home Premium, 2GB RAM, 22GB hard drive) about 3 weeks now- trouble is it drops the wireless connection consistently and regularly every three minutes- I've sat and timed it. Then it will immediately start reconnecting. Have used the laptop at home, at a coffeeshop, and at my university campus. Same behavior at each location. I bought this to replace my lenovo S10 netbook- which I absolutely lloved and never had a minute of trouble from with daily heavy use so this is disappointing. Also currently using Word 2007 trial and it goes buggy on me fairly regularly- won't save- claims not enough memory. I copy my text, shut down Word, reopen Word and paste my text back in, and then it will let me save. Again, disappointing given my last experience with a lenovo product was so outstanding. I'm thinking maybe the Word issue has something to do with Windows 7? But my main concern is the wireless dropping- Should I return the computer? Thanks for your help.
Solved!
Go to Solution.

UPDATE- I had already changed my settings to Maximum Performance a few days previous and dropping continued. Since this post I went to Device Manager and Power Management tab on the wireless adapter- I unchecked the box for "Allow computer to turn off this device to save power." Dropping issue appears to have cleared up- still have some seldom drops but nowhere near the regularity and frequency of before! Thought I'd post this in case somebody else has same problem.

E4200 v2 - Dropping wireless connection

I purchased this router as an upgrade from my Cisco/Linksys E3000 that I have had for over a year. I use wireless almost exclusively in my household and when the E4200 V2 is working it is great but then it seems to slow down. Actually it is not slowing down but dropping packets on the wireless segments after varying periods of time. The wireless connection does not drop ( i used vistumbler to view the connection in real time ) but all connections exhibit dropped packets. I had Amazon send me a replacement and it did the exact same thing. I even restored the router to default and setup just the wireless connection both using the Cisco connect and the web interface and the problem still happens. To test this I set a constant ping of the router's gateway address on my WLAN and observed 25% to 40% dropped packets. After a reboot it is more stable, but it becomes more unstable over time. The wired connections are solid and did not drop any packets but wireless is a joke!

There are many reasons why you experience poor signal or connection. Your intermittent wireless connection has a relation to the kind of setup that you have in your home or office. Is the connection dropping on all wireless computers or just one?
You have mentioned, you set the router to factory defaults and re-configured it. Did you try changing the channel on the router to either 1, 6, 9 or 11? There could be an interference with other wireless devices in the network (cordless phone, microwave etc.) since they work on the same frequency.
Try this and see if that helps.

Wrvs4400n keep dropping wireless connection

hi there,
has anyone got problem with wrvs4400n keep dropping the wireless connection? i tried to find out anywhere but not much hints are given how to solve the issue.
i have 1.1.03 firmware installed, and currently running on
b/g/n mixed on channel 9
wpa2 personal mixed security
the rest of the settings on default
i had the router running for about 3 months and most of the time i have to either restart the server to get the wireless working again. normally the wireless works ok until few days when suddenly I just can't access the internet using the wireless.
once i replug my computer using cable, the wireless router suddenly can give me IP address and the wireless return back to normal.
i have tried to use
different channels
changing to G/N, and B/G mode
change key renewal frequency
reduce RTS Threashold
accessing the wireless router from 3 different wireless network card
none of them really works, normally after few days, 1 week top, i suddenly lost wireless connection again. the SSID still there, i can authenticate, somehow the wireless just won't give me IP address
checking the website, it seems like i'm on the latest firmware from linksys and they don't seem updating the firmware anymore, is this product not supported anymore?
anyone knows of the same problem ? or has already solved the issue?

Hey Stewey,
I have a similar problem with my iMac G5. My roommate, who has an HP, bought a Linksys WRT54G when we moved in to our place and it gives me trouble with Airport sometimes. We use G only and WPA Personal. I updated the firmware in February and I swear it got a bit better, but it still goes out sometimes. If I move it just a few inches in any direction, generally it will start working again. Resetting it also helps sometimes. I don't know if its the fact that it doesn't say it's compatible with any Mac on the box, but it's annoying as all ****. My roomie rarely has problems with it (our rooms are the same distance away from the router), but my friend brought his PB over to do some work and he had trouble in my room as well. Is it Linksys, or is it Airport? I have no idea. Our router is out in the living room, next to the TV and Xbox 360, so it might be interference. If possible, try moving the router to higher ground and away from other electronics.
I tried looking up your router online to see if I could find anything else out. Didn't find too much info, but it says that you get free 24 hour tech support. You don't see that too often. If you can't figure it out, give them a call.
Good luck!
