[solved] netcfg drops wifi connection

Every time i connect to a wireless network (no matter how strong the signal is), after 1-2 minutes, the connection is dropped and i have to manually start it again. This never happens with the ethernet connection.
I use wifi-menu to connect to already created profiles. I have Arch x86-64 with a Broadcom BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01) wireless card and use the b43 driver from AUR.
After quick search in the forum, i found that the kernel should automatically reconnect or that i should apply a patch or that i should disable the QOS of the driver. As these suggestions are a bit old (especially for a rolling distro), i thought to consult the experts!
Please advise!

Disabling the QOS of the driver solved the problem.

How can I stop my ipad from dropping wifi connection?

Thanks for trying those steps out!
Rtbeal, I would recommend that you contact AppleCare so they can run further tests and diagnostics to help you solve your solution better.
If you can also access an Apple Store Genius Bar or Apple Authorized Service Center, that would be much better.

Why does my iPhone 6 keep on dropping wifi connection

after I used my iPhone 6 for a 2 weeks it started to drop wifi connection so I restored it and it worked for 1 month then it started to drop wifi connection again and restoring it dosen't solve the problem anymore and I updated it to 8.1.3

I have tried resetting everything and it makes no difference. Problem is same in different locations. Apple store verified problem which is why they exchanged phone for new model but wifi is still poor and drops frequently even though the iPhone 3GS in the family work perfectly on same access points.

My i Phone drops WiFi connection after just a few minutes and wont reconnect unless I reset the network settings and reboot the phone?

My i Phone 4s has suddenly started to drop wifi connection after nealy months of near perfect connections?
To restore a wifi connection I have to reset the network settings and restart the phone, this only fixes the issues for around 2-3 mins?
Other quick fixes like switching wifi on and off/ switching to airoplane mode for a few secconds have no impact.
This is really annoying as I am using my data allowence very quickly, and as the phone is continually searching for a wifi connection the battery time has reduced dramatically.
I just wondered if any one else has the same issue, and any suggestions as to how I can fix this.
Thanks in Advance

Reboot.
Restore (from backup)
Restore (as new)
Test after each step. If one of them doesn't fix the problem, make an appointment at the genius bar.

IPad Air after upgrade to ios 8 continue to drop WiFi connection

On September 19, I upgrade my ipad air to ios 8, and it had been dropping Wifi connection ever since. I was browsing using Chrome and next thing the browser hang up; then error message informed me to no network connection. By the way, my network was strong (5 bars), because I was streaming to my Roku in HD without any issues. At the same time, my Airplay do not want to stream the content in full screen either. It only mirror what have see on my ipad, not allow me to go full screen on TV. I hoped Apple will step up and correct this issue as soon as possible; I miss the good old day of reliable upgrade from Apple.

Yes, and hopeful 8.1.1 will help. It's supposedly in beta testing.

IPad randomly dropping wifi connection

I have seen quite a few posts regarding iPad dropping wifi connection. I have tried all the usual reboot router, updates, etc but the issue remains.
I need to keep switching wifi off then on again to re connect?
Does anyone have any better ideas than waiting for a bug fix?
Thanks

Thanks for the quick reply.
I have not had this issue outside of my home wifi so I suppose this points to a router issue.
When I read that others have had the same issue I presumed it was a bug.
"Updates" does mean router firmware updates.
I am using WPA2-PSK security but have tried WEP and WPA-PSK setting with the same result.
The router is a Netgear RangeMax model DG834PN
It is in g&b mode( whatever that means)
I appreciate your comments.

Why does my iphone 4 keep dropping wifi connection since ios5.0.1update

Why does my iphone 4 keep dropping wifi connection since ios5.0.1 update, it worked perfectly before, my wifes 3gs connects fine and stays connected while my £400 paperweight losses connection, thinking of going back to nokia! Sort it out apple!

If the "oh so Great Apple" were to monitor these forums then they might see all the problems
that the people who have paid good money for their devices are having, i suppose they can do no wrong
In your eyes, i just thought that if you pay a lot of money for a product that works fine, and you update
It with a firmware update that they kept going on about how good it was and it can do this and it can
Do that, then i think they should sort it out. I don't care if i "don't deserve to be an apple owner" or not,
The fact is i paid my money and it should do what its suppose to do, i moved from Nokia to Apple because
The N97 was crap and i put up with it for too long, and they didn't do anything to fix the bugs they just stopped
Selling it and basically said tough s**t, so now this is happened i hoped Apple whould be better but they seem
To be just like the rest.

ISA550W dropping wifi connection

Just wondering if anyone else has seen the IAS 550W dropping WiFi Connection
I have 2 SSID's on two differnet Vlans so they are seperated.
I have several users purly using WIFi connection and every now and then teh connection dropps out and then reconnects with in 20 -30 secs.
Havent been able to figure out whay the connection dropps in first place
As i have several Ap connection s avaiable on my machine i keep connecting to wrong network when my main connection dropps off.
Any on e any ideas?
Thanks
Nick

For testing purposes can you set a static channel on your ISA. This channel would have to be one that does not overlap with any of the other AP's channels. If your enviromental noise level is high then i wouldnt recommend keeping a static channel.
Hope this help with your troubleshooting

Hub 3 dropping wifi connection peripherals

Hi
First post here as never had any problems with Hub3, however, recently I'm losing the wifi connection to printer/airport express/other macs. they are shown as connected to the hub but my laptop is not connected to them. If I restart the router everything reverts to being OK.

Hub 3 dropping wifi. Problem solved so far.
I suddenly realised that I had swapped my iphone charger (which was sited very close to the router) with the wifes as she needed a longer cable, mine was the apple charger but got replaced with one of the cheap sort you can buy in the local shop. So I swapped it back and so far (5 days later) no loss of wifi. Bear in mind I was rebooting nearly every day.
As an aside, I have re-newed my BT broadband contract today and asked about a new router with my new contract. They offered me a HH4 for £35 + postage at £6.95 or a new HH4 FREE if I took the new contract without any discount for a year. Full price was £18, I'm on a discount at £13.85 rate for a year. This is not infinity. (not available as yet).
I asked if I could buy a HH4 at a later date for £35 + postage if my problems return. They said yes at anytime during the contract.

Ipad dropping wifi connection

I am noticing that my iPad Gen 1 is not maintaining wifi connections. It is dropping constantly. I cannot update my online newspaper subscriptions nor stream. Any solutions?

Try #5.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

TC drops wifi connection with hidden SSID on restart/logout?

All in all I'm new to the Mac family as of January and have only one complaint...holds true to the Airport functionality in Leopard. I experienced the Airport/2Wire DSL gateway dropping wifi signal I found plenty of on the support forums.
I figured buying the TC would solve the problem yet it still is a problem if I hide the SSID? My XP PC connects fine whether hidden or broadcast, in fact I had an easier time connecting and using TC via my work PC then with my MBP? I see and connect via wifi no problems in XP parallels or my work PC, hard drive connects as well. Yet as soon as I hide the SSID after I get my MBP connected, when I logout or restart I can not find or even search for the network. I have to enable/broadcast again to get the MBP to connect. Once I hide it I'm still good until I restart or logout of any of the accounts?

Hello:
I just purchased a new Motorola DROID 2 Global, and am having difficulty connecting it to my home WiFi network. My router is a DLINK 655 router, which I have set to 802.11n only with WPA2 encryption and I do not broadcast the SSID. I have gone through the setup process on the DROID 2 by entering the SSID on the phone providing my password etc. The phone keeps attempting to connect to the WiFi network, but just cannot do so. I have a Lenovo laptop which has no problem connecting to the network at the same time, and I have connect it many times.
If I change the router setting to broadcast the SSID, the phone will connect. But as soon as I hide it again, the connection will drop. The saved network setting on the phone will show "Not in range" even though I am standing right next to the router, and the phone connected to it just a minute ago when the SSID was being broadcast.
Has anyone else experienced this problem? Is there a solution to this problem or is this a known limitation of the phone?
A soft reset may resolve your WiFi connectivity concerns. Please remove the battery from your phone while is ON. Re-insert battery after 10 seconds. Power phone ON and allow it to register applications.

Windows 7 desktop drops WIFI connection

Hi -
I seem to see a lot of posts with this same problem, but no solution that's relevant to me. I have a DLink DIR 655 router that has the latest firmware installed (I updated it yesterday). One of the machines on my wireless network is having problems.
Two Microsoft Surfaces, three Windows phones, and one Canon WIFI printer all work fine, its only a desktop that uses a USB Wireless card that has the problem. I am currently using a Medialink MWNUSB150N wireless card. Note, however, that I had
exactly the same problems with a DLink wireless card.
The problem is that the WIFI connection drops frequently. The systray will indicate that I am connected to the wireless network with internet access. Then I will notice that web pages are not loading, but it will still show that I am connected
to the WIFI network and the internet. After a short time, the systray will show that I am connected to the network, but have no internet access. After some more time it will show that I am not connected, but will usually show that connections
are available. When I try to reconnect (my SSID shows as available at this point), then I get an error saying no network is available. At this point, my SSID no longer shows as available. I've run the troubleshooter probably 100 times over
the course of several months. It never helps. Rebooting sometimes helps. Sometimes it seems like I need to do a voo doo dance to get the connection back. Following is the result of running netsh wlan show driver.
Any ideas?

Questions:
Regarding your advice to check the wireless security settings - I don't know exactly what to do. I went into the router admin page and checked the wireless security - its set to "WPA-Personal". Other than that, I don't know how to tell if
its using TKIP or not.
The next time it fails, I will try your suggestion to remove the network and reconnect. I can't remember if I tried that at some point, so I'll give it a shot. I'm waiting for it to fail right now as I tried something yesterday that I think has
a low chance of success, and it hasn't failed yet. I noticed that the option to "allow Windows to turn off this device to save power" was checked for the wireless adapter, so I unchecked that value. I only think it has a low chance of
success, since the timing of the shutdowns was pretty random and did not "smell" like a power saving thing, but thus far it hasn't failed. I'm still within the window of randomness, though. Sometimes it works for a little over a day and
sometimes it fails after less than 5 minutes, so I'm just keeping my fingers crossed for the moment.
Comments:
Tried using different USB ports, USB 2.0 and USB 3.0, and front panel vs. real panel just in case there was anything weird going on. No difference.
Updated the driver using the "update driver" button. Windows believes I have the best driver installed. I did look for other versions, didn't find anything.

Dropping WiFi Connections after new Mac Min and Upgrade

First of all does anyone know why this discussion was archived when there was never a solution posted?
https://discussions.apple.com/message/12586041?tstart=0#12586041
Secondly (why I found that thread among many others addressing the same problem). I received a new Mac Mini for XMas (cool, I needed it) which worked fine with my other computer and devices (2 iPads, 2 iPhones, 2 Win7 Laptops and 2 Win7 desktops) for a couple days, so I thought. Now all these devices got along very well until Mr. Mini comes along. Then I note wireless drops occasionally, it seemed to come back so I wasn't too upset, yet and decided to deal with it later and enjoy my vacation.
Now, after I allowed Leopard to do its upgrade (I had deferred that) I now have all the above devices dropping wifi and physical LAN connections as long as this Mini is powered on. I shut it off, Internet is blazing, I turn it on, Internet falters and screeches to a halt.
Since all my other devices have worked cooperatively for several years and this device comes along and crashed the party im pretty convinced its not my router or computers. I am not interested in trial and error here. i have many better more important things to do and this is Apples responsability to figure out. I am a very savy IT dude (career professional) and want to get to the bottom of this for everyone.
Soooo.... What changed? Why does this device kill my network when it is turned on (note, no alterations from out-of-the box to any network protocol or config.) and why does a thread (one of many) without a solution get trumped on by Apple?
