My Wifi Connection drops with no reason
It is really often that my Mac Book Pro with Retina Display to loss the connection, It simply stop working, although the Wifi icon it shows the connection is still working.
I have discarded a router issue, since my other devices works perfectly.
I solve this issue by turning off and back on the wifi, but it is really annoying
Does anyone knows how to solve this, or If is this happening with all Mac Book Pro's (Retina)?
The wifi connection means you are connected to your router. Try changing the channel. Try setting up WPA2 security protocol.

Why is my WiFi connection dropping as soon as I walk out of the room where my router is located? Running OSX 10.6.8
Had ISP provider here multiple times. They switched out the router/modem on 4 occasions. They ran new fiber optic cables to my house. They sent a PC tech here with a Mac, and he was able to get a strong wireless connection, but mine, he said, was "weak."
I called Apple support. They had me remove the battery and clear the PRAM. It didn't help.
There's no point in having a wireless connection if I cannot walk 20 feet away from the router without losing the connection.
Do I need a new Airport Extreme card?
How much would it cost to get one, and what is the process of getting it installed? (no longer under warranty)
Deb GoonanMy ISP replaced my router FOUR times. I don't think that's the problem.
We already tried chanign the channel multiple times, channels 1, 6, 11 and even 9 and 4

Potential Fix to the WiFi connection dropping on MacBook Pro
I, along with a number of other people who have posted here, was experiencing WiFi connection drops after a few minutes on my brand new MacBook Pro, which is running OS X 10.7.5. Rather than going the route of plugging in a static IP address, I decided to look at other options within the Network Preferences. Under "Advanced," I went to the TCP/IP tab and set "Configure IPv6" to "Link-local only." By default it is set to "Automatically." The WiFi connection has not dropped since that change was made. It may not fix all the issues being experienced, but it might help at least some people having the disconnect issue.
Nice post, thanks!

Help needed to Replace existing routers due to connection drop with Extreme
I currently have an old linksys router connected to my cable modem in the basement. I then have a second router connected via ethernet to the first router located upstairs since most of my computers are upstairs. I am having alot of connection drops with most of the computers. ONe of the computers hardly even connects to the network. Almost all of my computers are macbook pros/macbooks/imac except for 1 or 2 pcs. I would like to start fresh with the airport extreme/express. Should I set it up similar in that I have an airport extreme base station connected downstairs to the modem and then have a second extreme/express upstairs via the ethernet connection. I do have a printer upstairs as well that most of the computers use that is connected wirelessly.
Any other tips?No,
Express has only one ethernet port which acts either as WAN input if plugged into a modem or as LAN output, if plugged into an end device (PC, Printer), so it cannot be used for input and output at the same time. I'd suggest you do this,
1/
- If modem must stay in the basement and cannot be moved upstairs
- Have modem in basement
- Run an ethernet cable from the modem to your Extreme's WAN port upstairs
- Have Express in the basement and connect it wirelessly
let it join your Extreme's network over wifi, if there is enough signal in the basement
- If there is no signal in the basement from upstairs' Extreme and Express finds
nothing or signal is unreliable, then you need to run an ethernet cable
from Extreme's LAN port (it has 3 in the back) and run it downstairs
and plug into your Express.
2/
- move the modem upstairs and keep the setup same as in 1/
- no difference, you still have to run the coax cable from basement,
so you drill no matter what
3/
- keep modem downstairs
- keep extreme downstairs connected to modem
- keep express upstairs and join it wirelessly to your Extreme's network
- plus side is - there would be no cables running upstairs
- downsides of this setup are:
you'll have router with only one ethernet port upstairs - so if you have"
multiple desktops, you will have to rely on wifi
Extreme's signal is stronger than Express's - I'd put it into a place where
my family spends most of the time
It all depends on your house setup, whether you have desktops or laptops only, ...
As a preference, I like to keep Extreme close to my main computer as I connect to it via ethernet rather than wifi (much better speed). My wifi is only for laptops and iPods.
Also, seing the Extreme's status light tells me what is going on without running to a basement when internet starts acting up.
Rule of thumb - if you can drill, then drill and take advantage of the gigabit speed as opposed to wifi's 100megabit or whatever your signal lets you get up to. This is very noticeable when streaming movies via Netflix, AirPlay etc...
If drilling is too much hassle, you live in an apartment unit or it's a transitory place for you, just use Wifi. If you are planning on living there for a while, cables will make you happier than wifi - no interference to worry about and better speed
It's up to you.
My apple TV is also connected to my Extreme via cable - speed is incredible. Wifi used to choke up every now and then. -
After installing Mountain Lion on my MBP Retina, the WiFi connection drops frequently (not happening to other devices around, like on an iPhone); it also takes a lot to reconnect after wake up. Does anybody have a solution for this?

Any wifi connection problems with new Macbook Pro 13" models?
I currently use a 15" Macbook Pro (about 3.5 years old) that has intermittent WiFi connection issues (intermittently loses signal). This seems to have been a very common problem with this laptop model. My kids, who use Macbooks, have no connection problems. In any case, I'd love to buy one of the new model 13-inch Macbook Pro's but hesitate because of my many issues with WiFi connectivity on my older Macbook Pro. Just wondering if anyone is experiencing connectivity problems with the new model?
I've never had Wifi connection problems with a Macbook and now with the 13" MacBook Pro I was flabergasted when I took my MacBook down the street to a coffee house with free WiFi. I went to connect to their WiFi and found my own WiFi connection listed. I thought this odd even though I was on the same block as my apartment, my apartment is six stories up. I connected to the Coffee Shop WiFi but it was really slow so I wondered if I could connect to my own home connection. I switched it over and lo-and behold I did connect! It was a good 300 feet away! I NEVER saw this with previously owned MacBooks including the black MacBook and the MacBook offered just before they moved the MacBook up to the Pro series.
So I'd say they have improved the WiFi nicely. -
Wifi connecting drops on Time Capsule when I sync iMac with appletv
I've had this issue ever since I got my 27" iMac and I can't figure it out.
My setting:
I live in a 3 bedroom apartment. Livingroom is at the right as you go in. Followed by room 1, then room 2 and right before the kitchen at the end is room 3(mine). I Have an apple tv in the living room, a 21" iMac and a time capsule that I use only as an airport base. I also keep a macbook in the livingroom. In my bedroom, room 3, I have my 27"iMac. Everything is connected to the Time Capsule for wifi as well as a couple of iphones and an ipod touch. Everything is updated with the latest software updates.
My problem is that every time I try syncing my apple tv with my 27" iMac, the time capsule looses the wifi connection and immediately starts blinking orange. I have to restart the time capsule by unplugging it and then the wifi connection is restored. For a while now I've been using a 50' ethernet cable that connects the 27" imac and the time capsule with the wifi off on the imac. This is the only way the wifi connection isn't affected when I sync to the appletv. I've tried resetting and restoring the time capsule several times without helping the issue. I also tried all 11 channels on the wifi connection as well as automatic setting for the channel but that doesn't seem to help. I clean installed snow leopard on my 27" iMac as well with no luck. At this time I don't know what to do, any help would be appreciated. I'm really tired of having that cable laying around. Thanks
~Cplease read this about possible sources of _*wireless interference*_, which may well be your problem.
wireless signals, if they have to travel over long distances or through obstacles (such as concrete walls or steel structures), will lose power. especially on the 5 GHz band you virtually need +line by sight+ in order to get a clean and reliable signal.
consequently, many users (including myself) resort to hardwired connections where possible. except my two airport express units and my iPod Touch, i have all my equipment hardwired to my TC.
additionally, syncing large amounts of data between devices heavily taxes your wireless bandwidth.
best of luck !

Wifi connection issues with Home Hub 5
Hi can any body help because I am starting to get very frustrated with the Home Hub 5 and it's wireless connection.
infinity 2 was installed at my house in the beginning of September, everything worked Ok for three weeks then for no apparent reason the hub kicked out all of my wireless devices (phones, kids iPods, tablets etc) at 6:45 one morning. When I got home from work I rang BT and was told to perform a Pin reset. This seemed to work but less tham 48 hours later at exactly the same time in the morning the hub kicked out all of my devices again, this time I just pressed the restart button on the top of the hub and everything reconnected but the Wifi range within my house had dropped. A few days later the hub kicked all my devices out again (each time it has done this the light on the hub has remained blue showing it is supposedly working OK)
One evening this week the hub of its own accord cycled through all the colours of lights indicating problems and that it was restarting. Today at 10:15 the hub kicked all my Wifi devices out again. I have contacted BT every time this has happened and told them about the poor range of the Wifi signal.
I do not want to be restarting/resetting my Hub every couple of weeks i need a permanent solution.
One of the reasons I switched from TalkTalk to BT when fibre became available was the fact that the Home Hub 5 was supposed to be the best provided router by any of the networks, being the only one that is an AC class router. The thing costs £130 if you want to by one. Quite frankly the £60 TP-Link dual band router I bought when I was with TalkTalk had a better range and was more stable. I would switch back to that if I knew BT's router settings (but they like to keep that a secret)
I really am beginning to regret switching from TalkTalk. Please someone restore my faith in BT.
Sorry for the lengthy rant but I hope you can understand why I've ranted for so long.
NickHi imjolly
Sorry its taken a while to reply to your post.
I wanted to try BT's latest attempt at a solution before i tried your idea.
Since your reply the Home Hub 5 has dropped the Wifi connection to my devices another three times.
The second time less than 30hours after BT's so called fix, which was to make sure the 5Ghz channel was not syncing with the 2.4Ghz channel. Tonight it went again and BT's response was to take the router out of smart channel selection and manually select channel 9,6 or 11 on 2.4Ghz and 36,40,44 or 48 on 5Ghz. Well I havent even bothered with that, if the prats at BT would look at their records they would see they have already suggested that.
This HH5 is the most unreliable piece of garbage i have ever had the misfortune to use. WHY OH WHY did I leave TalkTalk
I have tonight tried your solution. Fingers crossed that this works.

[SOLVED] WiFi connection drops
Hey guys,
I'm having some trouble with my WiFi connection lately as it tends to drop the connection every like 2-10 mins.
It is not directly linked to any specific action, it just happens while browsing the web, watching a video or chatting.
It's definitely not hardware related either as I do not have any connection losses when running windows on the same laptop (Dell Latitude E4300).
lspci: 0c:00.0 Network controller: Intel Corporation WiFi Link 5100
iwconfig: wlan0 IEEE 802.11abgn ESSID:"****"
Mode:Managed Frequency:2.422 GHz Access Point: 00:1C:28:1C:D6:8A

Power Management:off
Link Quality=61/70 Signal level=-49 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

Is this some known bug or is anyone else having the same problem? I couldn't find anything specifically similar to my problem on the forums and the rest of the web but maybe you guys know how to fix this?!
Cheers

You can try out to load the module with
modprobe iwlwifi 11n_disable=1 swcrypto=1
or, to make it permanent, create a file /etc/modprobe.d/iwlwifi.conf containing
#/etc/modprobe.d/iwlwifi.conf
options iwlwifi 11n_disable=1 swcrypto=1
That did it for me (i had the same problems: "wlan0: deauthenticating from 00:11:22:33:44:55 by local choice (reason=3)"). Don't know, if both parameters are needed, wasn't patient enough for testing.
Big maustu! that did the job for me as well.
This problem may be related to iwlwifi and some adsl routers. Everything was ok for me until we changed internet provider. The new provider (Fastweb, italy). placed their own router. Since then, my connection drops every 15 minutes or so and then it hangs. I have to restart network in order to reconnect.
I tried disabling networmanager and connecting with wpa_supplicant and wpa_supplicant.conf and fiddling with the file templates but the problem persisted.
I did pacman -Syu after we got the new router. Just to verify that it is the new router causing the problem I downgraded iwlwifi to previous version and the problem persisted. I didn't bother downgrading the kernel though...
Booting the same pc with another distro that loads iwlagn everything is ok. Another pc with ubuntu that uses iwl3945 is also fine. The problem seems to be just with iwlwifi, my network card and that f...g router which I have not access to.
My network card is Intel WiFi Link 5300.
The logs in case it really is a problem with iwlwifi and someone know how to deal with it.

Wifi connection intermittent with ipad... but fine with my other devices
wifi is working with my laptops, pc and smartphones. however, for some reason the two ipads would get intermittent connections and drop off very frequently. any ideas?
Others have posted similar reports on the forums. What kind of router do you have? What version of iOS is on your iPad? Did you always have these issues? When did they start?
I also have the connectivity problem between my Cisco WRVS4400N router and my iPad. My issues began immediately upon upgrading to iOS 4.2.1.
I've tried many (if not all) of the suggestions posted on the various threads in the forum. In the end I found exactly two router settings that made any difference.
1. Changing my router channel bandwidth from 20 mHz/40 mHz to 20 mHz caused a significant improvement in my iPad's network throughput. It nearly doubled as tested using the speedtest.net app available for download. +This did not, however have any effect on the connection drops.+
2. Changing my WPA2 key renewal interval from the default of 3600 seconds to 99999 seconds reduced the number of drop outs from "frequently" to 1 or 2 times a day. So it's not fixed, but reduced to the point of being tollerable instead of infuriating.
My opinion on the matter is that some part of the handshake that the WPA specification says must occur during a key renewal is failing. Since every other device I own works correcty--and even the iPad did prior to the upgrade, I assume this means that the problem lies on the iPad side, and not with my router. However short of putting my iPad and router into a faraday cage and analyzing the wireless traffic between them, I cannot confirm this.
The only suggestion I have had from apple support (and one you will see made frequently here) is to take my iPad to some unsecure wireless network and test it there. Which, of course, doesn't exercise the key renewal problem suggested above.
You should first contatct apple support and let them know you are having trouble. Have as much information as possible, and mention that others online are having similar issues.
Then, if they cannot help you, you can start with the suggestions here and in other threads.
Good luck. -
Wifi connection drops down. [SOLVED]
Hi, I'm having some issues with the wifi, in my notebook lenovo b5070. The main problem is that the connection drops down after 20, 30 minutes. I tried to change from NetworkManager to Wicd, but that didn't change anything. I also tried to create a profile and connect me through netctl, but again that didn't change anything. Other issues that I'm having are: Sometimes I can't even connect to the wifi, or if I can connect finally, and I try to request some website, the browser keeps idle and finally shows a "Server not found" message. Also the wifi signal seems pretty fine. I also tried change the tx, rts to the max with iwconfig, but this didn't change anything. I'm running out of ideas. Any idea?
Here is some info:

sudo modprobe rtl8723be fwlps=0
sudo modprobe rtl8723be ips=0
So far by now, the connection hasn't dropped (one hour since I made the change)
But is quite strange that when I do
[astinx@compu ~]$ more /sys/module/rtl8723be/parameters/ips
Y
I mean, the parameters changed or not? I also tried with setting with N instead of 0.
EDIT:
The drop downs come back shortly after. I find quite strange that I cannot manage the power from iwconfig
[astinx@compu ~]$ sudo iwconfig wlp9s0 power off
[sudo] password for astinx:
Error for wireless request "Set Power Management" (8B2C) :

IPad wifi connection drops - have tried evereything - any other suggestions
Hi all,
I'm experiencing the connectivity issue with my iPad whereby randomly it will stop transmitting data (ie cant go on the Internet). The Wifi symbol is till shown, but there is no data throughput whatsoever. To fix, I have to turn off the wifi on the iPad and turn it on again.
There doesn't seem to be any consistency to when this happens. It isn't related to coming out of sleep or the type of apps I am running. sometimes it will happen in quick succession, other times it won't happen for a few hours or maybe until the next day.
There are two iPhones, a Mac mini and and Vista laptop on the same network and none of them experience this problem. The router is a Sky broadband wireless router. It is set to WPA security.
I have tried:
- upgrading to firmware 3.2.2 and doing a restore
- resetting network settings on iPad
- restarting router
- changing channel of router (have tried 4 different channels so far)
- switching router from mixed (b/g) mode to just g
- forgetting network and reconnecting on iPad
- moving closer to router
- disabling auto-brightness
- setting brightness to maximum
- changing DNS on iPad
I have also tried most tips on this page with no joy:
http://appletoolbox.com/2010/04/special-report-fixing-ipad-wi-fi-issues/
It just seems like nothing is going to work, and I am considering returning this to Apple in the hope of either a replacement or a fix. This problem is really annoying and clearly and issue with the iPad as many other devices have no problems. Even if a replacement router may fix this, clearly the iPad is at fault here.
Does anyone have any other suggestions? If not, what do you think will happen if I take this back to Apple? Perhaps I can get a guarantee that they'll swap it with the next-gen iPad when it comes out?
Looking forward to your advice, thanks for reading.I don't have any real words of help except to say I went through something similar with an iMac. It would drop and pick up the wireless signal repeatedly but often sat there unable to connect. That was solved by something weird, like turning off the "show on screen" option for the airport wireless signal. I don't think you can alter that setting on the iPad though. My point is, if this was a problem out of the box I could see it being the iPad and that maybe getting a replacement unit would work (my wife recently bought a cheap B&N reader that would not access the wireless network, replaced it and everything worked). But if this is a problem that developed over time or just started out of the blue, then maybe it is a corrupted file or something that could be fixed with reinstalling the system. I know when you sync an iPod and iPhone with iTunes you have the option of wiping everything and reinstalling, so I am assuming it's an option for the iPad too. If you haven't tried reinstalling, perhaps that can be a next step.
Good luck!
Good luck!

Intermittent wifi connection drops on OSX 10.8.1
I've noticed since upgrading my Macbook Pro (early 2011) to 10.8, wifi connection would drop quite often if open Apple store and/or Itunes. I've tried changing wifi channels on my router, but with out success. I would have to turn wifi off/on to try restore connection, this works most times, but becoming very annoying.
I have the latest update 10.8.1 installed and no changes. My router is a dlink, about 2 yrs old.
Has anyone else come accross this? Any suggestions to try would be great.
ThanksYes, this happened to both my MacBook Pro and iMac after upgrading to ML and it is very annoying. I was hoping for a fix in 10.8.1 but no luck. This has been pretty widely reported so I was shocked when it was not addressed. I guess I have to call AppleCare and open a ticket.
Ok, enough of that. I tried everything - MTU setting, new location in network settings, taking the systemconfiguration folder (/library/preferences/systemconfiguration) and deleting it, and updating my routers firmware and none, none of them worked.
It seems, at least in my case, to be tied to 802.11n and possibly the 5ghz band. I disabled this on my router and am only using 802.11g and this and only this has cleared up the issue. This is really disappointing but at least I am not stopping and starting wifi every 3 minutes.
I hope this helps. -
Wifi connection drops on all apple devices
I have a linksys WRT120N router that i use to access the internet from (usually) a desktop, 3 laptops, 2 iPhones, 2 iPod Touches, an iPad, and a Playstation 3.
I have absolutely no problems connecting to the internet from any of the computers (all PCs) or the PS3. On all of the Apple products, however, the wifi signal drops every 15 seconds or so. It will be working fine, then all of a sudden the signal will just be gone and I have to go into the wireless settings page and reselect our wifi network to reaccess it.
The router is fully up to date on the firmware and is relatively new. Anyone have any possible fixes?This is what i hate ive already posted 2 disscusions about this and its falling on deaf ears.
i have apple tv, ipods, iphone 3gs and 4. imac and Ipad 1 and 2 using my wireless router supplied from Virgin Media. its 50meg broadband with the super hub.
before i get a smart arse reply............i had the same issue with Skys crappy broadband router........so its obvious its an issue with apples software/hardware. -
WiFi connection drops when I try to play video
This has been happening for months now. When I try to play video my WiFi connection gets dropped & it takes about 3 mins to pick up again. No problems on other web, YouTube is the main problem, but only because it's the site for so many vids. I've had other video sites drop the wiFi link too.
Anyone know how to fix this? And are Apple doing anything to fix this video handling problem (except for dropping the YouTube app from the last iOS release)?
ThanksHmm. Apple will charge me $20 for a one off call, so I'm not fussed on doing that first up. I thought for sure other people would've had the same problem as me so thought it worth asking here. There are no Apple stores where I am. Not even sure if there's one in the country. There might be one up north but that's the other end of NZ to me.
And it's not a service provider issue, there's nothing wrong with my internet connection at all. It's just video on the iPod.
Maybe this doesn't make as much sense as I think it does .
Honestly it is the stupidest thing that everything just falls over whenever I try to play video. I was thinking of getting an iPad (or a mini) but that's definitely on hold until I can sort out these issues. No point in an iPad if it might cough up the same problem.
I'll keep searching online & see whether anyone else has had this issue. If there's really no-one then I might have to cough up the dough. Shame as otherwise it's a brilliant wee device & I'm permanently connected to it.

Retina Display Support in Photoshop Elements 12
