Wifi unstable

My MacBook Air (MID 2012) keeps dropping the wifi connection after upgrading to OS X Mountion Lion.
Every couple of minutes the internet doesn't work but the wifi symbol says that it is still connected. After deactivating and reactivating the wifi it workes fine until the next wifi drop.
What I have alreday done:
- Reinstalled Mountion Lion (2x)
- Added other DNS Server
- Changed the MTU
- "KeepAlive" bash (ping router)
What should I do?

0. Forget everything above.
1. Start terminal (shell)
2. cd Library/LaunchAgents
3. mkdir Back
4. mv *.plist Back
5. cd /Library/LaunchAgents
6. sudo mkdir Back
7. sudo mv *.plist Back
8. cd ../LaunchDaemons
9. sudo mkdir Back
10. sudo mv *.plist Back
11. Restart Computer (TopLeft Corner Apple than Restart)
WiFi should work normaly.
NOTHING is REMOVED just MOVED.
OS X will recreate bunch of agents and daemons and put in mentioned folders for you.

Wifi unstable and extremely slow on my Aspire V Nitro VN7-591G-7.

Hi again ! My previous problem is now solved. But now I have issues with my wifi. The wifi works perfectly on other devices but on my Aspire V Nitro VN7-591G-7, it's just impossible to do anything on the internet... I've read it's a common problem and there are solutions. What steps should I follow in order to solve this ? I'm running Windows 8.1 by the way. I really like the performances of this computer so I wish to get rid of this stupid problem ! Thank you very much.

Can you describe "unstable and extremely slow" in more detail. Are you connected to the 5 GHz band of your wireless router or are you connected to the 2.4 GHz band? Are you having problems with all websites or just a few? Which web browser are you using? IE or chrome or firefox? What is the model # of your wireless router? Is your wireless router supplied by your ISP? Or did you buy it retail? What BIOS version is currently installed on you laptop? What BIOS version is designated as the latest version on Acer's website? Does the problem occur when you use other people's wifi such as a friend, relative or neighbor? Have you tested it somewhere besides your home? Does Acer's website list an updated wireless driver for your computer? http://us.acer.com/ac/en/US/content/drivers

Wifi unstable, networkmanager doesnt show errors

My wifi is currently very unstable, sometimes my latency jumps up and down and sometimes connection is lost even though networkmanager still displays two bars signal strength. After turning off wifi and then turning it on again it usually works for a few minutes before it starts doing weird stuff again.
I have a thinkpad t440s and gnome 3. When I boot windows it works flawlessly, so im guessing its a problem with a driver or a configuration. I just cant figure out what it is.
lspci -k:
03:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b)
Subsystem: Intel Corporation Dual Band Wireless-N 7260
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
Its a intel wifi card, so i guess that should be okay?

I dont have any problems with my wifi at all, but I figured id post my output since I use the same driver and have some of the same output. I have a Lenovo Thinkpad T530 with:

Subsystem: Intel Corporation Centrino Ultimate-N 6300 3x3 AGN
Kernel driver in use: iwlwifi

and I have zero problems with signal strength, and my wifi is not at all unstable:

As you can see, I dont have muzzel's time event error, and my output looks roughly similar to neubauten84's output. All 3 of us have different wireless cards... If you want my output for comparison on something, just let me know.

Wifi unstable with lion

WI-FI unstable with lion upgrade

patoody and mauricio1956 ,
There was a 10.7.3 Airport update for iMacs that may help you if you have right vintage of iMac, according to this article:
http://support.apple.com/kb/DL1501
If it doesn't help, please start a new topic thread and tell us what router you have make, model, and vintage, as well as which iMac you have. Also tell us if the issue is reproducible in a remote WiFi hot spot or not.
laoistom,
If you are using Time Capsule, please post to the Time Capsule forum. Otherwise just post to the Time Machine forum.
RRK, This is a user to user forum. And the issue you have is not with an iMac. I suggest posting to the MacBook Air forum a new thread so someone can isolate your issue.
Everyone here note, the mauricio1956 posted this way back in October, and has not posted since. It is likely because they didn't provide enough detail, or posted in the wrong forum to get advice. Generally posting a followup post on a thread is only recommended if you have a solution for people. Tagging along you won't generally get results to get a solution to your enquiry as your post is hidden from most thread readers..
mauricio1956,
If you are still with us, let us know which update you applied, what router you are using, and if the issue is reproducible on any other computers.

TimeCapsule Wifi unstable (when on a non-Mac devices)

I have a TimeCapsule and I connect many devices to Wifi: --> iMac,Windows Vista PC, Samsung Galaxy Tab with Android, Iphones, etc..
I am having wifi crashes mainly when connected on a Vista PC or Android Tablet. Suddenly the internet crashes and I need to reconnect manually. When streaming online content (video from Youtube or audio from interent radios) fron non-MAc the crash will happen at some point (sometimes earlier, sometimes later)....but this is not limited to content streaming as it also happens when surfing the web.
I noticed that the wifi network disappears from the list for a while, as if AirPort restarts. I need then to reconnect manually.
Whern on a Mac device, this seems not to be a problem and I do not experience crashes....
I upgraded firmware to the latest version, but nothing changed.
Does anyone know this issue and the reason why and how to solve it?
Unfortunately my experience with Mac products is that if you remain within the "Mac world" using Mac products, your are good to go, however compatibility with other brands is an issue, and this is a great inconvenience when we talk about an Air Port!...
Thanks a lot for any advvice as I tried everything to solve this and this forum is my last hope.

Different products use different wireless chipsets.. even apple have used different wireless cards in each Generation of the TC and each update of the computers they build. But at least Apple only works with a small range of hardware and can sort out the drivers. Drivers can and usually are the problem, although some wireless chipsets really just don't work well together.. you will notice this on any brand.. to brand difference. Wireless is voodoo still .. it is about 50% science and 80% black arts. (in voodoo you don't need to add up to 100%).
Vista .. shudder.. was built with known issues in the wireless management that were never fixed. Upgrade that computer to XP.. or win7. Vista is just a dog. it will be faster and more stable. Replace the wireless card to match the TC.
Some of the earlier Andoid also are known to have issues.. check if there is firmware update or anything available to help. Android had a really nasty bug. Cannot remember much about it now.. so google.
I would suggest you at least make the wireless have some hope of working.
You will need to do the following.
1. Use SMB names not Apple type naming. SMB is short, no spaces, pure alphanumeric. Apple uses spaces and particularly apostrophe.. don't. That applies to all names in the TC, so change the TC name and wireless name.. give a different name to 5ghz.
2. Use WPA2 Personal (AES) security. Use a passkey of 8-12 characters same rules as above.
3. Lock the radio channels. TC is set to auto by default and will wander channels to find most clear.. the wandering is a problem.
4. You might need to either lock IP via dhcp reservation or manually set IP on the device.. Often issues involve address failing and constant reconnections. It will eventually fill the table.
5. You must use 5.6 utility on the Mac so you can check the log of the TC and actually see the wireless clients.
6. Do not expect vista to get any better.. but at least download the latest driver for the exact wireless card used from the wireless manufacturer.
If none of this works.. use the lateral thinking approach..
Get a cheap TP-Link, edimax etc wireless router. Use it in AP mode.. and plug it into the TC. Use a different name and wireless channel to the TC. Use that for your non-apple products.. it costs $30 or so for N-lite which is all you need. Simple easy effective. That doesn't mean that vista will ever work of course.. vista is fundamentally flawed. Nor can I guarantee early android.. but at least it will be right kind of product.

Wifi unstable -- battery drain

One day I will get to the bottom of why my phone will periodically decide to try and cook itself by discharging the battery. Caught some good evidence today, while it was eating the battery, the wifi signal was in and out for over an hour, which causes the dreaded Google play services to wake up, and keep everything else awake while doing something terribly important a lot. Chickens and eggs, was the signal bad because so much current was being consumed by play services, was the phones wifi bad or was the router bad? Perhaps others with the battery discharge issue could grab the same screen shot and see if wifi is the culprit for them.

I have the same problem with WiFi and off, the issue was Google Play services, this is what I did settings > apps > all > google play services > clear data > uninstall updates > restart the phone > update the app > check again .

MacBook Pro Early 2011 WiFi unstable connections

I have been having issues in trying to stay connected to my WiFi network using my MacBook Pro 13" Early 2011 Version on Mavericks 10.8. I will have connection for anywhere between 20 to 30 minutes, sometimes less then that, and then it will just lose connection. It wont come back on until I either reselect the WiFi connection and possibly enter the password again, or I just turn it off and then on again to have it autoconnect. I have not had a single issue with my LG Nexus 5 phone that has been on the same network without a single dropped connection. I need to see if there is a fix for this as I need to have a stable connection for my school work as all of it is me having to turn in assignments online. Has anyone else had this issue or ever heard of it?

Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.

Mountain Lion on Mac Mini - WiFi unstable for Internet Sharing

I have a Mac Mini Mid 2010 MC270LL/A previously on 10.6.8 and everything worked fine.
I have it plugged into a Plasma TV via HDMI and network via CAT6, but it also doubles as a WiFi access point via Internet Sharing.
Previously WiFi was secured via WEP, I don't recall if 10.6.8 had anything stronger, most likely not, otherwise I would have gone WPA2.
I have now done a clean install of 10.8. ie erase hard drive, boot from USB and lay down a clean install of Mountain Lion.
Software update downloaded a new Firmware, which has also been applied and rebooted.
Now I've set-up Internet Sharing, used same SSID (maybe should have picked a new one in hind-sight), but secured via WPA2 - the only option.
Previously my Macbook Air 13" MC965LL/A, had undergone the same clean install treatment via wipe, then boot from USB and install 10.8.
The Wifi worked flawlessly with Macbook Air on 10.8 connecting to Mac Mini on 10.6.8 (Secured via WEP), no drop outs, connected even after sleep.
Even the power nap feature worked really well, I was impressed that when I open the lid on the Macbook Air, I had emails already waiting for me.
Now with the Mac Mini on 10.8, it's a really sad state, constant WiFi dropouts, my File Sharing disappears, Screen Sharing stops, it's a real pain.
I'm hoping it's not the new firmware, I guess I'll find out when I restore to 10.6.8 and see how it goes.
Anyone else have issues with Mac Mini WiFi on 10.8 ?

This is the System log on the Macbook Air while sleeping - connected with wifi to Mac Mini under 10.8

After 2.0 Upgrade original iPhone WiFi unstable and not connecting

I upgraded my original iPhone (8GB) to OS 2.0. I had some issues getting it upgraded with "problems accessing the iTunes Store" but once thoese resolved seemed ok. Even bought and synced Super Monkeyball.
I now notice that in my home where I have two airports (old G Extreme and a G Express) neither will connect to the iPhone for more than a few seconds and for the most part the phone doesn't see them.
Anyone have this issue and any suggestions for resolving?

Hi Menk - do me a favor will you? Go into Settings > Mail, Contacts, Calendars > and then scroll down to "Calendars". Question: How many sub-functions do you see?
After I did the upgrade, I have two sub-functions. I look at the same path on a 3G iPhone, and see they have three. The 3rd sub-function is "Calendar Type". Do you have that on your upgraded iPhone?
Also, when you are in the Calendar apps, on the top left hand corner. do you have a "Calendar" button? I don't have one after my upgrade but I see that 3G does.
Look forward to hear from you ...

Ipod Touch 5 random restart and wifi connectivity issues

Good day to you sir...
My Ipod Touch 5G 32gb model white has issues towards random restart and wifi unstable even though I have full bars and a working wifi internet connectivity
Here are details that might help on my case..
I bought the Itouch 5 on singapore exactly around January 2013 registered on January 1 on Apple web for warranty.
Around early Feb, i experienced some random restart and I tought it was just some bug after update, it was gone and came back around late march with some wifi issues, but not regularly, only around certain cases on using it for a long period of time. I am still experiencing it now.
The device never experienced drops,dents, nor water damage.. it is protected by an Ozaki case and screen protector bought in a Mac store. Never been Jailbraked. I used it for music, videos and gaming purpose. I have 3 idevice other than the Itouch (iPad 2, Ipad w/ retina display and Ipad Mini with no occuring problems both updated to ios 6.1.3 (so is the itouch). I would like to know what course of action should I take about this problem. I have restored the Ipod Touch 5G via iTunes but the problem still occuring both wifi and random restart. I bought the device on a legit mac authorized dealer. (Power Mac i think) in Singapore, but I live in General Santos City, Philippines. I would gretly appreciate if you give me exact details what course of action should i take.
P.S. my Ipod Touch 5 is running on iOS 6.1.3..

If you restored to factory settings/new iPod and still have the problem that indicates a hardware problem.
Make an appointment at the Genius Bar of an Apple store..

Galaxy Note II Unresponsive for minutes at a time

I'm on my 3rd galaxy note 2. My first one had an overheating problem that caused the battery to last for 2 hours even though it was idle. They ended up replacing it for me. My 2nd one was actually perfect. I had zero problems with it for nearly a year until the day after the 4.3 update, the screen went off and never came back on. I just got my replacement about a week ago and I'm having an issue with the screen becoming unresponsive for minutes at a time.
I factory reset the phone yesterday thinking that maybe I had a rogue app installed but it seems that any time I try to launch a game or if I try to browse the internet while an app is updating, the phone is unusable for a few minutes. It's like it can't multitask. Eventually it'll come back with the phone at my home screen with my background image gone, but eventually it comes back too. It's similar to when windows explorer crashes and it reloads. I'll go through the same process for 2 or 3 more times before the game finally launches or the internet browser is finally usable.
Before I call this phone defective, I was wondering if it's a problem related to 4.3 that I should be aware of? I installed a monitor and it looks like with no apps open, from a fresh reboot my ram is 50-80% used which doesn't leave much room for opening apps or playing games. I even installed a virus protection and scanned for a virus (i know viruses on smartphones is a stretch) and it returned no issues.
Any ideas? I could factory reset it again, but I just did that last night and it didn't help still having the same problem with very minimal apps reinstalled. One note, I factory reset it with the restore from backup functionality turned off, so the apps I did install were from scratch, not my google account.

I decided to call in. I tell the rep my problems and he tells me to launch the phone in safe mode. Done. I could reproduce the issue. It then says wifi unstable. The phone freezes with wifi on. Tells me to turn the wifi off. No more freezing while in safe mode, I guess wifi is the problem didn't think that was an issue before. He tells me that wifi issues have been reported but none of those issues cause the phone to freeze, he said that samsung told them to tell customers to turn that feature (ie: wifi) off until the next software update. He said samsung is working on a fix for the wifi issues but said there's no eta. I asked him for his gut feel and he said phones that are newer than 18 months normally get priority, given that the note 2 was release in november of 2012 and we're in 2014, that he estimated 3-4 months for the next update. I know I can't hold him to that but even if he's right, I have to leave wifi off for 3-4 months?...Now to the best part, "Since there is no freezing with wifi off in safe mode, and in safe mode the phone behaves in the state samsung designed it to be in, I've determined that it's not a hardware or operating system issue, so there's nothing I can do for you. I'm sorry I couldn't send you a new phone or resolve this problem for you, I hope you find a solution for the software issue you're having, good night."
Rather than get mad I realized I wouldn't get anywhere with him so I didn't try to push the issue. I know I have unlimited data so it's not that big of deal, but wouldn't you consider the phone not working regularly with wifi turned on a hardware or os system problem? It's not like I can uninstall and reinstall wifi. The drivers are embedded in the system and since it's a refurb phone, who's to say that the parts that were refurbed are really factory oem?
Now I'm stuck with a phone that is unusable randomly for 3-5 minutes using the phone normally with the mobile network/wifi because the agent didn't consider the problem to be hardware or os related and the only way to keep it from having issues is to not turn on wifi and keep the phone in factory default settings.
I'm not going to threaten to leave or go somewhere else because it would serve no purpose, maybe that's why there was no attempt made to help me other than saying no from the beginning of the conversation, but in my 15 years of being a loyal customer, you would think "i hope you find a solution on your own" would be after sending me a new device if the problem persisted.

4.3 upgrade issues - battery drain, unstable WiFi, freezing, wake-up lag/freeze

I've been (also) experiencing issues since my Galaxy S3 was pushed the 4.3 update on the morning of 1/11/2014. The worst is the battery drain - losing more than 50% of battery life within 4 hours of 100% with only minor texting during that time - with the charging process taking nearly 3 times longer to fully recharge. The moment it's removed from the power cord, it drops to 98%. This was not happening before update.
Today, I called Verizon's technical support who recommended a factory restore. Since I read endless posts/experiences of this not resolving the issues, I chose not to take that path and to work with Samsung to understand when a fix would be pushed. After 45 minutes on the phone with Samsung explaining the issues as if they'd never heard of such problems with the update - I was told that I clearly had water damage to my battery which was causing all of my issues. Sure, and everyone else who owns an S3 in these forums has the same water damage. Of course, the moment I asked to speak with the Samsung rep's superior, our phone connection grew dim, sputtered as if it were a bad mobile connection, and suddenly disconnected.
I experience the "Unstable Internet Connection" to WiFi when no other phones have issues with these networks. They're the same networks I've always used - but since the update, they're now "unstable".
The lag to wake up when I receive a call or text sometimes takes 10 swipes and a few freezes before it finally unlocks.
I've downloaded no new apps since the upgrade, yet apps I used regularly prior to the upgrade now randomly freeze on me, requiring me to remove the battery to restart the phone.
Unless Verizon is willing to let me out of the 2-year contract since I'm not able to use my phone in the manner to which we'd agreed in that contract, they had better start acknowledging a large-scale problem with this update and work dilligently with Samsung for a speedy resolution. Just seems odd that this update was pulled back in November for these exact issues, yet Verizon chose to allow it to be pushed to their S3 users in January without resolution from Samsung. Gee, wonder if it's so we'll all upgrade to the S5 as it's release is a few months off. Hmmmm.

I agree, the upgrade is awful. All I can do is complain publicly and if all of us do, maybe something will be done sooner.

Unstable wifi on battery

Hi all,
Recently I started having problems with my laptop's wifi. It started losing packets, which caused the network being very unstable, even when I am standing next to the router. However, it did not do this all the time. This made it hard to debug. After some weeks, I now found out that it has to do with running on battery. If I run on battery, packets drop and when I run with the power cable attached, the wifi is just fine.
I have an Alienware M17x R4 running arch linux in combination with xfce. My wireless card is the Intel Corporation Centrino Wireless-N 2230 (rev c4).
I made 2 test reports with mtr connecting to google, to compare the situation with and without powercable. You can clearly see the difference.
(I removed the Ip's and domain names for privacy reasons)

I also tried turning the powersave off with
iw wlp8s0 set power_save off
but this didn't make any difference.
Does anyone know how to solve this?

I have no idea what it mght do, but xfce4-power-manager also installs upower.
How about this. Can you boot up to the multi-user.target (hopefully without also starting any of teh xfce4 stuff -- particularly upower) and then use the internets from there. See if the battery powered machine in the multi-user.target acts the same way. I'd suggest even using basic networking tools to connect, though I think netctl would also do the trick, since it is just a set of shell scripts around those tools.
I also have an Intel Centrino 2230, and it was a great card (I have since moved on to the only dual band card that is usable with my machine). I do have a coupel friends though who had nothing but problems with the iwlwifi module in general. I have seen a lot of work going into the iwlwifi module in terms of kernel commits, so hopefully things are getting better. I have been meaning to give that card another go, just to see. Maybe I'll do that sometime this weekend. If I get around to it, I'll report back on how things are with 3.11rc6.

Iphone 4 running 4.3.5 wifi very unstable/will not connect to network

Hi all iPhone users. Im new to this so please bear with me. I have an iPhone 4 (had for about 1 month or so). I have recently updated to the new 4.3.5 software. Sice then, my wifi seems to be very very unstable. Im only about 10ft from my router and when I go to connect, I get an error saying 'unable to join network'. I previously had an iphone 3gs and that connected fine further away.
When my iphone 4 does connect, the connection lasts about 10-15 secs and then it will not load any web pages although it shows its connected. I have tried all methods on previous threads but nothing seems to work. Ive also tried retting my router and changing the wifi channel to make the signal stronger but nothing seems to work.
Ive seem some threads where people have 'put them in the freezer' but im not willing to do that as the phone is only a month old. Ive tried the network reset, the hard reset, re-installing itunes and trying the update again but it nothing seems to work.
Any help or advise would be much appreciated.
Thanks

Hi folks,
SOLVED
iPhone 4 wasn't having any joy (and neither was my new 4s).
Tried turning OFF the security on the router, connecting the iPhones (yep, they connected OK) then turning on the security (WPA2-PSK [AES]) and both iPhones still connected.
So, it looks like this is the way to solve a non-connecting iPhone 4/4s with a Netgear WiFi router.
Hope this helps others with the same problem.
Regards
RB
