MBP 2011 dropping wireless connection

my wifi connection drops every 2-3 minute and reconnects in 15-20 seconds.when I connect to the internet with my neighbor's modem it works fine.
Although I made a very wide research i found nothing helpful about this issue. Can you help me to solve this dropping problem?
i tried to delete /Library/Preferences/SystemConfiguration folder and restart computer.. it didn t work
i tried to change my modem/router channel.. it didn t work(i tried 1,6,9,11 channels).

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!

Hi buddy,
> I kept O.S. original for a week and the problem was the same
If you had the same problem with factory settings you should test another router. Maybe its a malfunction of router or something else (not compatible to your WLAN card).
Furthermore ask the manufacture of your router if they know something about this.
In worst case its a hardware malfunction of your notebook. You should contact nearest service centre. I believe they can fix it under warranty, because A660 is pretty new notebook.
Good luck! :)

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.

New macbook pro 2011 weak and dropping wireless connection

Just looked throught this part of the forum and found out there are a lot of people out there which seem to have the same problem as me.
I purchased a new modell 2011 MBP on the very first day from our apple store.
At home, sitting directly beside the wireless router I didn´t noticed anything wrong.
I have got beside of the Mac OS a bootcamp Prt. with Windows 7 on it and everythign works fine so far.
Five days after purchased I started traveling on business and at present we are for some weeks in Melbourne. Were having a wireless connection in our appartement and here I have got massiv problems with my connection.
We are having altogether four windows mashines with us, my IPad, my Iphone, another HTC smartphone, and my new Macbook.
All the other devices connecting to our room wireless without problems. The net strengh is not fantastic but the other devices bringing it up to four bars on the windows wireless symbol in the task bar. None of the other computers where ever loosing the connection.
Only my macbook can not make it over three bars and its going on and off. Donwloads fail freuquently because the conection is interrupted more than one times..
In my opinion this problem is even worse on the Windows OS and a bit better but far away from beeing good and acpetable on the Mac Os.
I hope its only a driver issue and there is no hardware problem with the new mashine. Other than this I love the new notebook and I am very satisfied with its performance.

Hi,
I've noticed similar behavior - specifically with the new 2011 MacBook Pro 13 and 17" models (tested) on Cisco infrastructure - using a 1252 and 3500i/e series APs running in dual-band mode, with 5GHz preferred. I've seen the transfer rates when in close proximity to the AP move between 72mbit and 243 - occasionally 300. My 2010 system in the same position is a solid, dependable 300.
They did modify the wireless chipset in the new 2011 MacBook Pros to replace it with a true 3x3 802.11n device. Cisco have long praised the Broadcom chipsets so I will see if their wireless team can advise me on what this new gear is capable of.
I currently look after a very large deployment of wireless LAN equipment so my wireless performance is absolutely critical to my work - the 2010 system was a godsend and a testament to how wireless devices should be built. It looks to me like this could be a software issue so I only hope Apple resolves this ASAP. I'll hang on to my 2010 system for now...

Actiontec MI424WR dropping wireless connection intermittently; wired connection works

I've had this router for about two years, with no issues.
Beginning on Saturday, our two laptops and phones began losing their connection to our wireless network, dropping the signal every 30 seconds or so. I tested the wired connection by plugging the laptops directly into the router, and both computers functioned properly - no issues connecting or staying connected. I have my Roku hard-wired to the router, and that also has had no issue, so it'd definitely a problem with the wireless signal to my devices.
Spoke to a CS rep, who had me first check the internet signal (green, blinking sporadically, which I was told indicated no issue with the connection), then had me reset the router and unplug. No dice. She said the internet signal seemed fine, and that "everything looked good on her end", whatever that means. They're sending a new router which I'll receive today or tomorrow, but I have trepidation.
Has anyone else had this issue? I saw alot of router issues on the forums, but wasn't sure if everyone was having this specific problem (just wireless connect issues).
Solved!
Go to Solution.

This turns out to be good advice. I changed the channel on my router settings to 11 (per an earlier post on a different thread), and I haven't had an issue since. Here's the original post: "01-21-2011 11:32 AM that type of problem doesn't sound like a router issue, but instead sounds like a wireless transmission issue. you may be able to resolve that fairly easily.. Try to change the wireless signal. you can do that in the router. open a browser, and go to http://192.168.1.1, user name is admin. and the password is most likely the serial number found on the service tag of your VZ router unless you changed it. Once you login successfully, go to the top and hit wireless, then on the left basic security. then go to option 3 which is channel 1, 6 and 11 and are the only channels you should try. So it will likely be set to auto, change it to 11 and put the check for keep settings even after reboot (Directly under the channel) and then hit apply., after you hit apply, test your connection out, if you notice a difference, leave it like that until the problem happens again, and if it happens again, go back into the router, and try channel 6, test it out. and then finally 1 if the first two don't work."

Dropping Wireless Connection & Speed Slowing Down

Hi,
Up until a week ago I had two BT lines, I will call them line 1 and line 2. Line 1 (front room) was used purely for phone calls, and line 2 (middle room) had Broadband activated on it. When it came time to renew the yearly line rental I checked and had it confirmed by BT that the available Broadband speed was faster on line 1, so I decided to cancel line 2, and move my Home Hub 4 into room 1 having arranged to activate Broadband on what in theory should be a line that gives a better speed.
My current problem is two-fold. Firstly I am not yet getting the line speed that I was expecting. I have spoken to the Technical Help Line, and understand that following the activation of Broadband on the line in Room 1 I should wait 10 days for the available speed to stabalise. Currently I am 7 days on from line activation.
A few days ago I was getting download speeds around 2.70 Mbps, with upload speeds around 0.38 Mbps. The IP profile for the download speed at that time was set at 2.77 Mbps. The IP profile for the upload speed was set at 0.45 Mbps. Over the past week I have done numerous speed checks and found that the speed did vary, as might be expected, but was generally always around these figures. Because of the line check speeds I was given by BT's own staff I was expecting the available speed to get better, not slow down! I was originally advised to expect line speeds of between 3.5 Mbps - 5.5 Mbps.
Over the last 24 - 36 hours the speed has slowed down, and a few minutes ago these are the figures I observed:
Download speed achieved during the test was - 1.3 Mbps
For your connection, the acceptable range of speeds is 0.8 Mbps-2 Mbps.
IP Profile for your line is - 1.33 Mbps
Upload speed achieved during the test was - 0.34Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.45 Mbps
Line speed then is one issue, but there is another.
My second, presently very frustrating problem is that even though the Hub 4 is consistently powered, and maintains a steady Blue light showing that Broadband is available, my wireless connection that I receive from the Hub keeps dropping. I should add that the distance from the Hub 4 in Room 1 to where I work with my laptop in Room 2 is only about 15 - 20 feet. I used the old Hub 2 until a few weeks ago, and neither my daughter on her laptop, or myself, had any problems with 'dropping' the wireless signal, whichever room we were in, or even if we used our respective laptops elsewhere in the house. I was convinced enough by the publicity 'blurb' to believe that Hub 4 was more reliable, with fewer drop-outs. So far this has not proven to be the case.
I know that I need to wait a few days more till the 10 days are up, but would really appreciate some kind soul commenting on the above. I have looked at the Logs, but without knowing what segment would be helpful in aiding a diagnosis of my two issues I didn't want to provide unnecessary information. So if any particular element of the Logs would be useful, please let me know.
Yours in hope,
Alan

Hello again,
With your help I was able to locate the place to change the channel manually, which I did, thanks for that. It only resulted in a marginal improvement, but any improvement is good I guess.
HH4 has now been showing a steady connection for three + days, so, as requested, here are the noise stats:
16:14:16, 26 Nov. ( 76.170000) DSL noise margin: 22.00 dB upstream, 12.20 dB downstream
16:14:16, 26 Nov. ( 76.080000) DSL line rate: 448 Kbps upstream, 3104 Kbps downstream
I have done several speed tests and they all show broadly similar results, namely that my download speed is usually around 2.67, whereas my IP Profile is set at 2.74.
I don't know whether this is worth mentioning but I only have an old style BT socket on my line, not one that has a test socket inside, so I can't do any of the tests using that facility.
Although my broadband connection has been stable and active on the HH4, as far as using wireless to connect my laptop in another room I do still get several dropped connections each day.
Even when I am connected to my HH4 by wireless, and my signal, as now, is only in the four bar bracket, by looking at the other Networks that are active in my street/area I can see, although it is rightly secured, that someone is using a HH3 and the signal on that is powerful enough to register a full five bar (excellent) strength on my laptop. How near or far away from me that user with a HH3 is I do not know, the point is however I can receive a more powerful and consistent signal from their Hub than my own. I must confess to being puzzled by that. What could be the reason?
Is there any further help or guidance that you can give that might assist in raising my IP profile, in the hope that my speed might increase? Or do you have any further suggestions as to how I might reduce the noise on my line to a more acceptable amount, so that my signal might give me a better wireless connection?
Thanks again for any advice or help you are able to give.
Regards,
Alan

Urgent! T420 with N6205 keeps dropping wireless connection and cannot recover

Hello everyone,
I bought my T420 model with N6205 network card last December, since then, the wireless connection never functions well. Here's the problem(it happens in my apartment):
Every once in a while (normally within four to five days), my wireless connection drops automatically. It would first appear as no connection and it'll try to reconnect, then it appears as successful connected for 5 to 10 seconds(but definitely no internet access), and it'll drop the connection completely again, then automatically repeat :reconnect, drop,reconnect, drop ... never stops. Though I can still use cable to connect to my router to have internet access.
This problem occurs to none of my smartphones, ipad, ipod touch, my old laptop and my roomates' wireless devices under the same wirless environment. They always have solid wireless connection.
Of course, regular approaches have been taken trying to solve the problem:
1. manually disable wireless functionality on my T420, and enable it again
failed
2. reboot computer
failed
3. go to power manager and turn PCI express off
failed
4. uncheck allow the wireless LAN radio to be turned off when inactive
failed
5.updated to the latest driver through lenovo
failed
6. restart router
successful
So it may be that I've got a bad router? This is why I didn't post my problem in the first place, since I was hoping it may disappear with other routers.
I changed to a new router, the problem persists.
There's no way I can restart the router every time when my laptop looses connection, it'll affect the other users.
Based on the description of my problem, I believe there's a great chance there's something wrong with my T420 rather than with my router.
Is there anybody who can help me with this?
Can lenovo staff see this post?
Any suggestion about who I should turn to?
Thanks a lot.

What security mode are you using.
WPA or WPA2? You could change the router to WPA only and see if that helps. I have see some portable devices that don't negotiate the protcol properly but never a notebook. If you have Bluetooth turn it off. It seems to affect my 1x1.
I have the 1x1 card and it pretty bad connecting at 24 to 48 Mbps only with a good signal. I don't know why Realtek is used in a Business class notebook. Maybe some others can add what they have and is working 100%.

WRT54G V8 Dropping wireless connection

Hello,
I have an issue with my Lynksys WRT54G V8 (firmware upgraded to V8.00.2). No problem whatsoever with wired connection, however, it appears to drop my wireless connection every 10 or so minutes. I appear to be able to connect to my neighbors unsecured connection with no problem however.   The only way I can figure out to reconnect is to power the device off and on again. Disabling and enable the wireless adapter on my laptop does nothing.
Here is what I have tried:
I have moved the device to be closer to my laptop (it is now approximately 6 inches away).
I have changed the channel to be 11 instead of default 6.
I have changed client lease time from 0 to 999
I have upgraded the firmware to 8.00.2
Verified that my SSID is unique
This is the 3rd wireless setup I have done (separate places, 1 office and 1 in my home and this one in my vacation home). This is the first time I have had any issues. It is the same laptop, I have the same model of cordless phone in my home as the vacation home.   The only thing I am not sure of is the firmware level of the other two devices. They are the same model.
Any suggestions before I return this device and buy another model?
Thank you

After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you have not done this since the last firmware upgrade, please do this now, and see if it corrects your problem. If you saved a router configuration file, DO NOT use it.    If the above does not fix your problem, then read on:
There are many causes for poor wireless connections, and many solutions:
Set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
Also, you did not mention what type of encryption you were using. If you are using WPA2, or "WPA with AES" (= WPA2 ), then note that Windows XP requires a patch to run WPA2. Go to Microsoft Knowledge base, article ID=917021 and it will direct you to the patch.
Sadly, the patch is not part of the automatic Windows XP updates, so lots of people are missing the patch.
If the above does not fix your problem, download and install the latest driver for your wireless card.
If you continue to have trouble, try the following:
For wireless g routers, try setting the "Transmission Rate" to 54 Mbps. For wireless n routers, try setting the "n Transmission Rate" to 162 Mbps, and the (wireless g) "Transmission Rate" to 54 Mbps.
If you still have trouble, download and re-install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps.

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 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?

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.
