M40X-250: Unstable wireless connection 54mbps

Hi,
a month ago i bought a new m40x-250 and a brand new US robotics maxg router, the problem is, i'm using it wireless and we set it on 54mbps, we secured the network in the recommended version of us robotics which is WPA, so everything looks normal, but the problem is after several minutes connection (internet) falls out and then its back, like ten times in one hour.
So i thought it's my laptop, so i sent it back to Toshiba, complete check up, they found nothing, system works perfect! got me thinking and i put the router on 11mbps, now the wifi works excellent, but my question is howcome not on 54mbps?? It should be cos it's both that standard, on the router and the laptop (802.11g) now i use 802,11b.
the only thing i can think of is my pc card.
Can someone give me some advice here??
Thanks!

Hello Kris
Unfortunately many users reported about this appearance and it is obviously because of WiFi card. If you check Wireless board you can find lot of topics with similar theme.
A few days ago I have found interesting article about WLAN connection interrupts under SP2. Try to disable this.
Go to START > RUN > put services.msc. Please found option Wireless Zero Configuration and change the status. I really dont know if this can help but you can try it.
My notebook has no the same WiFi card and I can not test it. Please let me know what happen after status changing.
Good luck!

[SOLVED] unstable wireless connection

Hi,
Wireless connection has some troubles. I don't get connection drops or anything in everyting.log mentioning errors with wlan. I tried wicd, Networkmanager and netcfg - but alas - no better results in any of them. The problem is that when checking mail, upgrading packages, ... sometimes connection cannot be made. Most of the time, running the same program immediately a second time, won't give this error. Less error-tolerant programs just crash/quit with an error-message.
Errors are like (in Dutch, I tried an English translation after ***):
Herleiden van v3.lscache4.c.bigcache.googleapis.com... mislukt: Naam of dienst is niet bekend. *** Failed to resolve from ... Name or service unknown.
wget: kan host-adres '‘v3.lscache4.c.bigcache.googleapis.com’' niet herleiden *** Cannot resolve host-addres
I've on the same laptop Sabayon and Ubuntu running where those problems do not occur.

The thing is, I cannot run it when it happens, because it is not a disconnection. It is more like small hickups. Fault-tolerant applications won't give an error. But using wget/curl might fail 1, 2 or three consecutive times, but can succeed flawlessly a 4th time. :-/

R400 - unstable wireless connection

Hi there,
I have a fairly new Lenovo R400 and since I upgraded from Vista to Windows 7 I seem to log on and off every other minute, which is really annoying. Anyone knows the reason for this?
I've installed all drivers from the disc that Lenovo sent me. I've even been looking for additional drivers on this page, without any luck however.
Any good suggestions?
Thank you
/ Andreas
Solved!

Extremely unstable wireless connection

Since Saturday my connection just stops working every 15-30 minutes. Disconnecting and reconnecting solves the problem, but I'm sure there's a better option than netcfg -r'ing all the time.
There was a kernel update on Friday (3.1.9 -> 3.2.1), so I suspect that could be the problem. Any ideas?
EDIT: I noticed there was a new kernel update available, the connection seems to work for now... It worked for over 2 hours yesterday before acting up, though, so I'm not sure if the problem's actually solved yet.
EDIT2: Kernel update didn't help

Well, there's only so much you can do on your own. Still, there are some things for you to consider.
First, we still don't know if it's a bug that only affects you. It may be more widespread, but I still wasn't able to find anyone reporting similar trouble as you have. It may be caused by the fact that your wifi card isn't that common - it should be supported by the kernel, but the fewer people use a device, the longer it may take until a bug gets recognized and fixed. It still may be caused by something in your system, but I'm out of ideas on how to figure that one out. And since it's a kernel we're talking about, I'm of the opinion that the kernel developers should be made aware of the issue. Here are some guidelines on how to report kernel bugs, but it would be appropriate if someone more accustomed to this process could step in now and give more information on how to proceed. I never had to do something like that myself, so what I'm saying is just what I could find out by googling and directly on kernel.org.
And second, reporting a bug won't fix your immediate problem. Even if you report it, we don't know if it ever gets any serious attention, and even if it does, when it's going to get fixed. Staying on outdated kernel can hardly be called a solution either. So, these are the only options I think you have, besides reporting a bug, which you should do either way:
- keep using older kernel and watch changelogs and your bug report mailing list for any development
- be ok with having to reconnect every now and then while using fully updated system, and again keep watching the situation. You may consider using tools like networkmanager or wicd, which should be able to reconnect you once you lose connection
- since you're using a desktop PC (which I assume you don't move around), consider using ethernet connection for now if that's an option
- get a new wifi card. Simplest solution available, if working wifi is your only option and you can spare the cash, they aren't expensive nowadays anyway. Obviously not a very elegant solution, but it will work for sure
Sorry I couldn't help any more. Again, someone please step in if you have any more ideas.

T60 -- Bad Wireless connection. Help please!

Hi Guys, my T60 has unstable wireless connection problem. I make sure the radio is "ON". It gets connected to the DSL network but it gets disconnected on and off ( the radio turns off by itself sometimes). Something wrong with my Intel PRO Wireless driver 3945abg? Can anyone guide me how to fix the problem??
Thank you!!
-meLittlebee

Hi there,
I'm having the exact same problem - installed the OS (Windows XP Pro) adding SP3 and updating all drivers.
Then I connect to the wireless whitout any problems. I go to sleep, and next day wireless don't work!
The Machine is a T60 2008-WGV. I have made a image of the clean disk with Clonezilla, and therefore I can restore the OS quickly to a working wireless, but I find it quite anoing to have a clean OS every morning, in order to use network.
anyone please?

Wireless connection unstable on Leopard

Hi, I just got a new iMac as part of a free upgrade because my local store could not seem to fully repair my previous iMac and I am having issues staying connected to the internet while using Leopard.
Everything usually starts off fine but it seems that if I'm on my online game for 30-45mins the internet will suddenly disconnect. When I go to the list to view my available networks they are all missing for several seconds before reappearing and the computer automatically reconnects itself to my network only to disconnect another 10-15 min later and repeats the process. I've only had this computer for a few days and have managed to keep a stable connection of several hours only 2-3 times.
Before when having initial connection set up issues there seemed to be a problem with a driver that was easily fixed when uninstalled and the computer restarted. My only theory is that the computer may be over heating causing it to loose the ability to see my router but I don't know if there is a way to improve fan efficiency while using Leopard.
Please help me out.

Hello Tigerhawk,
While I am not an expert on Apple Wireless, I may be able to offer you some general advice and perhaps narrow down your problem description.
From what you wrote, I deduce as follows:
- On your old iMac, you also used wireless and never saw this issue. In other words, your current issue was introduced with the installation of your new iMac?
- You are still using the same Access Point?
- Your iMac is bootcamped and you first experienced the issue on the non OS-X system.
- Later, when using OS-X, you experienced the same issue.
Just a few more questions to get things into perspective:
- You are using 10.5.3 (I suppose). Given this is a recent update, you also saw the issue on 10.5.2?
- If there are other people in your household, do they suffer the same issue?
- Are you using 802.11n (Airport Extreme)?
- What brand is your Access Point?
- If all wireless items are Apple branded, are you using 802.11n only, or 802.11b/g?
- Are you using encryption? If so, what type? WEP? WPA/WPA2-Personal/Enterprise?
Lately I installed Airport Extreme on my own Mac and found the connection to be sluggish and would sometimes loose connection or experience signal deterioration. While installing the base station (Airport Extreme), I pretty much went the default way with the base station in Bridge mode.
I found that giving the base station a fixed IP address (instead of the default DHCP) and also manually configuring the DNS addresses made the wireless experience a lot better. Of course, this could be an isolated incident. Before I gave my Macbook (10.5.2 at that time) to my girlfriend, I also noticed irratic connection stability. But that was on a non Apple branded Access Point, so not a fair comparison. This Macbook is in her house, so I cannot test at the moment. As another comparison, the iMac in my GF's house (latest generation May 2008) is just screaming fast using an Airport Extreme base station. I did not observe dropping of connection. The Macbook still did drop connection, even when on the Apple Base station. Wired it is very fast and she's happy with that for the moment
You can try perhaps as follows for testing purposes:
- Remove all security from your wireless connection (open system).
- If that improves the situation, move to WEP.
- If that this works fine, move to WPA and observe.
- If all of the above do not change your experience, you may try the manual configuration I mentioned earlier.
Hope this helps in any way.
Best regards,
Eirram

Equium M40x - Wireless Connection not working

I have recently changed ISP from Orange to Virgin [cable] I was using the Orange provided Livebox with my Laptop and there were no connection issues. Virgin have supplied me with a Netgear WGR614 wireless router.
Now my Equim will not connect to it. Can anyone offer a newbie some help or advice? Is there a driver update needed or will i need to purchase a new wireless card for my laptop? Currently my wireless network connection is via an Atheros AR5005GS.

Do you see the wlan of your router and can you connect to it? Remember, you have to enter encryption key again for your new router.
If not, I think the trick with Netgear router is, to enable wlan functionality.
To do so, you have to connect router with normal lan cable. Then enter IP adress of router in internet browser, you can find this information in manual with username and password too.
Try this, as I don't know what exactly is your problem with your wireless connection.

Dear Steve, will anything be done about this wireless connectivity issue?

This is no fun whatsoever....
I am telling you - browsing interenet on iMac is no fun, seriously.

People, help me in refining this list - did I leave something out?
P.S. I was thinking lately, why, after spending so much money, should I spend several days already, in agregate, trying to understand the issue and how it should be resolved? Have I not paid for not having such problems?

Here is a lot more:
http://www.macintouch.com/readerreports/wirelessnetworking/topic4035.html
Highly interesting is the post of J.Exby which i reproduce here:
For months I've not been alone in holding to the notion that the airport client software on Mac OS X 10.4.x has been problematic and unstable in certain (noisy, crowded, channel overlapped) wireless environments. Issues littered around the Internet Mac forums include problems of networks appearing, then disappearing. This is a difficult problem to pin down, given the difficulty of reproducing the conditions that might cause wireless network dropouts.
A major symptom of the problem was seeing the constant messages of:
"An error occurred joining the AirPort network" (Try Again) (Cancel)
when attempting to connect to a wireless network, despite that network being seen, having correct security settings, etc.
Various temporary fixes/ideas floated around the mac community have included:
- reseting pram, nvram and PMU
- installing 10.4 from scratch, instead of 10.3 to 10.4 upgrade process
- Repairing permissions, run Combo updaters, etc
- putting system to sleep or reboot for temporary connection fix
- applying AirPort 2005-001 patch (or not)
- upgrading (or downgrading!) AirPort basestation firmware
- changing AirPort channels
- enabled (or disabling) Interference Robustness
- disabling Bluetooth and BT peripherals
- removing WEP/WPA passwords out of Keychain
- running Keychain First Aid on user/login keychains
- buying new AirPort extreme cards
- replacing AirPort base stations with other vendor hardware, etc.
With the stability of our Windows XP clients now (after driver updates) and the change from Apple base stations to Belkin Wireless Pre-N Router having no appreciable benefit for our Mac notebooks, the OS X AirPort client software suspicions only grew.
During troubleshooting I always have
Applications--->Utilities--->Console
and
iStumbler (96)
running, and I watch output as wireless scans are performed.
From the Terminal I also run:
/System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport -s
and usually see constant
AirPortScanner WirelessScan error -2013261821 airpInternalErr
messages.
After two days of testing (and fixing?) I am even more convinced there are bugs in the powerpc 10.4.x AirPort Extreme Framework!
This is what I found:
Environment at our office:
- wireless Network A (802.11g channel 1, WPA personal)
- wireless Network B (802.11b channel 6, WEP 40bit ascii)
- wireless Network C (802.11g channel 11, WPA personal)
(WAR-marching around our office exterior shows at least 12 outside wireless networks found at various signal strengths!)
Test systems used:
- iBook G4 (10.3.x and 10.4.5)
- Powerbook G4 (10.4.5)
- Intel iMac (10.4.5)
Primary symptom on iBook: networks not displaying long enough under the AirPort icon/menu (or Internet Connect) to connect to ANY network reliably! Perhaps connect to Network A intermittently, never even see Network C.
iStumbler showing some networks respond to poll, then immediately stagnate/disappear.
Primary symptom on Powerbook: stable connections to Network C most times, difficulty "switching" to Network B or A once moving closer to source. Usually stable "seeing" networks via AirPort menu icon, but still have occasional dropouts (due to fluctuating signal strength or interference?).
Primary symptom on Intel iMac: NO PROBLEMS! Can connect to (and steadily "see") all valid Networks A, B, C !
iStumbler constantly polls all available networks, with no dropouts.
Steps taken:
1. Wipe iBook hard drive, install 10.3 from dvd. AirPort signals unreliable.
1a. Perform all 10.3.x Software updates, Repair Permissions, reboot. AirPort still unreliable.
2. Reset PRAM, nvram, PMU. no improvements.
3. Reseat AirPort Extreme card, ensure antenna is firmly plugged in. AirPort still unreliable.
4. Wipe iBook, install 10.4.3 "fresh" from Full retail version DVD. AirPort still unreliable.
4a. Perform all 10.4.5 Software (combo) updates, Repair Permissions, reboot. AirPort still unreliable.
5. Hold down the Option key, and click on the AirPort icon in the menu bar.
select About AirPort...
pay particular attention to each system showing:
iBook: AirPort Framework 421.13.0
powerbook: AirPort Framework 421.13.0
intel iMac: AirPort Framework 426.1.0
Aha! A big difference with the AirPort Framework component version on the Intel iMac!
6. So, using the Terminal let's get this newer Apple80211.framework onto the iBook.
First on the intel iMac:
cd /System/Library/PrivateFrameworks
sudo tar cf ~/intelApple80211frame.tar Apple80211.framework
Copy this intelApple80211frame.tar file onto a USB thumb drive, CDR, iPod, scp, etc. to copy it onto the iBook (home directory).
7. With the tar file copied into the home area on the iBook, turn off iBook's AirPort via the menubar icon.
Now launch Terminal and:
mkdir backup-framework

8. Turn Airport on via the menubar icon.
iBook now has HUGE improvements in wireless connectivity! It can "see" all Networks A, B, C reliably and can connect to any of them when in range (having enough signal strength). Switching between networks is successful 90% of the time. Occasional message of:
"An error occurred joining the AirPort network (Try Again) (Cancel)"
usually works after clicking (Try Again), whereas before Try Again almost always failed.
I am unsure how this newer Apple80211.framework will affect future Software Updates on the iBook, but frankly I could care less now that it's able to access all of our wireless networks!
I am unsure if this is the magic-bullet solution for a majority of people, but I'm stunned that Apple appears to be providing new and improved Apple80211.framework software with the intel iMacs, but many of us have been fighting AirPort problems on PowerPC platforms for months!
Come on Apple, OS X 10.4.5 should contain the SAME software component versions for ALL CPU platforms!

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.

Lenovo G400s Wireless Connection Limited Access on Windows 7 Ultimate - 32 bit

Just bought Lenovo G400s, install windows 7 ultimate - 32 bit on it.
It turns out the wireless network driver need to install manually, the disc driver that came with laptop was for windows 8.1. So I went to lenovo website, put on the series and download the wirelss network driver which is around 250 MB.
I installed the driver and connect to the wireless network. My office wireless was on security and use static ip. I changed the ipv4 ip static already. It connected for a while, 1-2 second then lost connection. I checked with ping to google, got 2 records of live connection which is very short. After that it try to reconnecting itself again and again with status said "Limited Access"
I search in google, read some forums about problem in different series, so I use another computer go to Intel website to download latest driver. Got it installed, but it's still the same.
I try download broadcom driver, but it's really different and doesn't work at all.
Now I don't know what to do.
Windows 7 Ultimate - 32 bit
Inter(R) Centrino(R) Wireless-N 135
Driver Provider: Intel
Driver Date: 1/26/2014
Driver Version: 15.11.0.7
Digital Signer: Microsoft Windows Hardware Compability Publisher
What makes it weird, although from intel website said the driver date is in 3/21/2014, and the version is 16.11.0, but this information I get from device driver was different.
Here's the intel's website if you're wondering:

Can anyone help me?
Solved!
Go to Solution.

Today I want to install windows 8.1 on it, because the laptop came with windows 8.1 driver disc.
However, I try the wireless connection once again , one final try before I clean install the OS.
It turns out the internet connection is connected. Ping is quite stable, got a small drop. Nonetheless, IT'S CONNECTED!!!
I don't know what happened, I tried thousand ways yesterday and gave up. Today I don't set anything just try connecting with static IP set the ipv4 just like I did yesterday, and it connects without hassle!! is there a pc fairy or what?
The possible way I can think of is the router's internet connection's got restarted since It's a new day at office.
Despite how it solved still mystery to me, I think I mark this thread as Solved.

Question about wireless connectivity...

Where exactly in the Verizon contract, or Terms of Service does it state that wireless connectivity is NOT guaranteed as solid connectivity, nor are provisioned speeds while wireless as well? Would be a wonderful thing to have proof of just in case, if you get my drift.
Solved!
Go to Solution.

It's there in the TOS; but finding you the exact paragraphs and lines is not productive.
A brief amount of research would provide:
>that the fastest most common in recent years wireless throughput is 54Mbps (wireless G) which is only at half the speed of a wired connection.
yes, one might be able to receive 108Mbps, but what that actually is is (2) 54 Mb streams hitting you at the same time. Your 'receiving' equipment must
be capable (neither the 2 streams nor the receiving quipment is provided by your ISP)
yes wireless N is out, but one usually has to purchase own equipment for that (not provided by Verizon) (or any other ISP that I am aware of)
>As has already been mentioned by posters before me, the various things that can possibly affect your wireless reception include everything electronic in your immediate area AND ALSO any of your neighbor's electronics if you share a common wall
>even the computer you are trying to use, in too many ways, can affect your wireless reception
SO there is really no way anybody could guarantee wireless

Printer loses wireless connection when it goes to sleep?

My printer loses wireless connection to my router when it goes to sleep and I have to input the WEP key again. As long as the printer is awake it works fine. The wireless light remains on.
Printer is HP Officejet Pro 8500A Plus and the router is a Verizon 7500.

If you mean WPA, that is good.
Let's set a static IP address for the printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') to 250
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router's IP (on the Network Config Page) for the gateway.
- Enter 8.8.8.8 for the first DNS and 8.8.4.4 for the second DNS. This is Google DNS. You can choose another external DNS if you wish.
- Click 'Apply'.
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.

Macbook slow wireless connection

Hi guys, just got my new Macbook, and its wonderful except for one thing.
My wireless connection was just fine for the first few days, but ever since today its been horribly slwo. The other windows pcs on my wireless network are still fine, so the problem seems isolated to the macbook. I used the network utility to ping my router and the result of low pings of 2, 3 ms followed by a fat lag spike of 1000+ ms ensued. The ping log looks like this.

Anyone know what might be the problem? The internet was very fast until this afternoon when it stopped working. I looked around online and it seems like a lot of other macbook core2duo users might have this kind of network problem as well. If i sent it in to applecare would they just change the airport card inside the macbook?
I have tried changing the SSID and the broadcast channel to make sure they didn't coincide with any of the surrouding networks and that didn't solve the problem. I also tried connecting to some other networks and got the same ping problem.
Thanks.

Since the problem suddenly appeared, it might just be interference.
(There is an "interference robustness" setting in airport that may or may not help.)
Do you live in an environment with a high density of wireless devices?
Did you install any software or updates since yesterday?
Have you tried restarting your router?

Thinkpad T440p unstable wifi connection

I purchased a Thinkpad T440p during last Christmas. I always have unstable wifi connection. I have updated all the drivers, changed to different wifi enrionments, and restored my laptop to factory conditions. Still, it is very unstable. Anybody here can give out possible solutions? I know I am within the warranty period. But I am using laptop everyday, and don't want to ship it to Lenovo for a long-time fix.

Try this driver?
