Slow discovery of wifi networks

Any suggestions on how to improve the discovery speed of known wifi networks?
I usually use a wired connection but when I do use wifi it can take 10+ minutes for my routers SSID to appear in the list of available networks. Other weaker nearby networks appear almost instantly but mine takes ages. There's no channel conflicts or obvious sign of interference issues and my iPhone, printer and work laptop can discover and join the network almost instantly.
I've tried deleting & re-adding the network dozens of times with no obvious effect on discovery speed.
Any ideas would be appreciated.
Thanks.

I changed my router from channel 11 to auto and it's now working fine.
There was no sign of any interference on 11 and indeed all the other wifi devices could use it without problems & the macbook itself would eventually connect.
But now that it's auto it connects almost instantly.

T500 running very very slow on specific WIFI network only???

Hi,
This problem is driving me absolutely crazy. It means that I can only use my PC at home if I use a cable connection to the router....
Problem is that on my home network my T500 is having a very very slow access to the internet via wireless. On all other wifi network I have connected to there is no issue and speed is high.
Also several colleagues have been here with their T500 and none of them experience any issues with speed. We all run on the same t500 model, ordered at the same time and with same setup. We use Windows XP.
I have tried to update all drivers, I have called my network provider who have updated router software, changed frequency and all other things they could do to avoid interference etc.
I have two other PC's at home - none of them have any issues.
I have done a web seacrh and could see that I am far from alone with this strange issue of a T500 being slow on only a specific network (often a home network). Many different routers are involved, so I dont think it is arouter problem (would also mean that my colleagues identical t500s would have issues right??).
Have there been any reolution to this T500 problem??
Best regards and with hope of "salvation" :-)

Which model of wireless card are you using? Intel 5100 or 5300 or thinkpad version?

Why is my MacBook Air slow on any WiFi network?

I have been having a strange issue with my 2013 11" MacBook Air (Mavericks 10.9.2). It has seemed very pokey on internet lately. The past couple of weeks in some places I have not been able to get online via wifi, including GOGO on Delta, which has never been a problem (iPad and iPhone got on right away). So back to my house, which is on a Time Warner 30Mbps cable internet service. A browser speed test is only showing 1-3Mbps, which is on a Time Warner 30Mbps internet service. I am getting terrible speeds as I mentioned. Today I reset the modem and my airport extreme. Then I took a MacBook Pro I have and went direct into modem with ethernet cable and speed went into the low 50Mbps!!!!! So then I took the same MacBook Pro and went back to wifi, speed test still very strong - 30Mbps or better. But back to my MacBook Air, and speed test only 1-3Mbps. I also tried speed test on my iPhone, and it also shows 20-30Mbps. So now I am convinced something is weird in my MacBook Air - the network and airport extreme don’t seem to be the problem. I dont know what else to do on the MacBook Air to try and resolve this issue. Can anyone give me any ideas? I tried zapping the PRAM, still no help. Thanks for any input or ideas!

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

Very slow speed on wifi network

I have a wireless network provided by an Extreme-N base station. When I copy files between Mac Pro and MacBook (connected via wi-fi, both 802.11n capable), the maximum transfer speed is 1-2 MB/s.
Some network info: encryption is WPA2 Personal, radio mode is 802.11 n (b/g compatible), channel is automatic, transmit power is set to 50%. Range is unlikely the matter because speed doesn't increase when both computers are placed next to the router.
Here's my AEBS configuration file:
http://dl.dropbox.com/u/405913/daniel/AirPort.baseconfig
Any ideas why speed is so low?
Thanks

I did like you advised. Now files are copied at 3MB/s. Link speed is 270Mbps on Mac Pro and 300Mbps on Macbook.
Screenshot of AirPort statistics window:
!http://img687.imageshack.us/img687/3933/airport.png!
(transmit power is 100% in both cases)
I had to switch it back to b/g compatible because there are two 2g iphones that also need to be online.
One strange thing about Macbook is that Info window in Network Utility shows ethernet info in the Airport pane, Airport info in Firewire pane and firewire info in Ethernet pane.
Any ideas how to raise the speed at least in N only mode?
Thanks for help!
I don't know if it matters, but I've forgot to mention that my AEBS is early 2007, the one without gigabit ethernet.

MacBook Pro slower than iMac wifi

My MacBook Pro (2 yrs old), is MUCH slower on our wifi network, than my imac (5 yrs old).
The MBP is actually closer to the router, and when I run speedtest.net, the imac is showing better/faster results than the MBP.
Any ideas would be great.
thanks

The operating systems are the same, as well as browsers. This has been going on for some time now. I notice it especially when updating software, like iphone, from the Apple servers via itunes or app store.
Regular web browsing with Safari is also much slower on the MBP. I usually have it connected to the power cord too, so that's probably not it. any other ideas?
Ill try disabling IPv6
thanks!

ITunes downloads fast on old Mac mini but slow on brand new Macbook Pro on the same WiFi network?

Hi all,
I have an old Mac mini that's from around 2008 and runs on Snow Leopard. I also have a brand new Macbook Pro with retina display that's running Mountain Lion. Both running iTunes 10.6.3.
I never noticed anything wrong with my MBP's connection speed until last night when I downloaded a free TV episode from iTunes. The download speed varied between 20KB/s and 40KB/s and it took me 7 to 8 hours to download a single episode. I checked my internet connection but there was nothing wrong with it, SpeedTest.net told me I had a download speed of 94MB/s and upload speed of 80MB/s, it was only iTunes that was unbearably slow.
Today I was browsing iTunes again and was planning to buy some movies, but again it took forever for the trailers to download. So I fired up my Mac mini just to see if it would be just as slow. Turned out my Mac mini could download the same trailers from iTunes at a much higher speed than my MBP (around 3MB/s on the ones I tested).
So what gives? They are on the same Wifi network provided by an Airport Extreme, and although my iPhone and iPad are also connected to it, no one else is doing any heavy duty downloading.
Thanks in advance!

Using Speedtest, all my iOS 7.1 devices are showing slow internet download speeds on my home WiFi network.

I have four iOS devices, an iPad Air, an iPhone 5S, an iPhone 4, and an iPad2. All but the iPad2 are running iOS 7.1. The iPad2 is still iOS 7.0.4. I am only getting 1mbs download speeds with the iOS 7.1 devices. The iPad2, as well as my Windows 7 laptop on the same WiFi network, are getting a full 15mbs download speed using the Ookla Speedtest. I have tried resetting the wireless router, as well as resetting the network configurations on the iOS devices, rebooting the devices, etc., but the slow speeds persist. While I can't definitively tie the issue to the iOS 7.1 upgrade, I distinctly recall running speedtests on the iPad Air in the past, and getting 15mbs.
Any troubleshooting suggestions?

Thanks for the reply, Jim. I double-checked my wireless router settings against the recommendations in the link you provided. Only one setting was different. I had the 2.4GHz channel width set to auto, and the recommendation is 20MHz. I made this change. The 5GHz channel is disabled on my router.
After the change, I got mixed results. My iPhone 5S now gets over 15Mbs, but my iPad Air gets less than 1Mbs. My iPad2, as well as my laptop, continue to get over 15Mbs. I don't think the issue is with the router configuration at this time. Any other suggestions?

Why is my iPad (3rd gen) so slow on wifi? My other 2 iPads are blazing fast but the new one is slow on the same network, Why.

I have all three ipads. My home wifi gets 30 mbps speed. Every device in the house is really fast. However, the Newest iPad (4G, 64G) is very slow on any wifi. 4G works acceptably fast, but the wifi is very slow. I've restarted, resynced, reset, restored, and this dosn't help. Any ideas?

Slow wifi network with iPhone

I have a latest model 16GB iPhone and am seeing extremely slow internet speeds over my home wifi network. Some of my friends are having the same problem.
I have a fairly modern ethernet-only ADSL2+ belkin router, which is connected to my time capsule. I'm using my time capsule to provide wireless internet access. There are two macs on the network with 802.11n cards, and a third mac with 802.11g, as well as my iPhone. I also have an airport express (i'm fairly sure it also has 802.11n) which is used exclusively for printing.
When I run a broadband speed test, I get 4 to 5Mbit on the mac with 802.11g. But on my iPhone I'm only seeing speeds of around 0.5Mbit!
Does anyone have any ideas what is going on?

Hi imobl,
Im having the same issue as virkdaman even after I updated to iOS 6.0.2. The Wifi network gets disconected frequently even when I use home wifi while my iMac is connecting to home wifi with no issue. My Iphone5 has never been jailbroken. Is it I have to wait for another iOs update to get this issue fixed?
Thanks

Slow WiFi Network Caused by MacBook Pro

Hi all,
I've had my MacBook Pro for about 3 months now but have noticed the WiFi download speeds are particularly poor. Having read a few articles, I've tried a number of "fixes" but to no avail. What makes this more puzzling is that it doesn't just affect my MacBook but EVERY device connected to my WiFi suffers from poor speeds when my MacBook is switched on.
If my MacBook is off I get about 17Mbps but when it's on, I only get about 3Mbps. The pings are slow too - around 300ms. I've tried switching off Bluetooth and WiFi but still other devices are affected. The only way to restore decent download speeds is to turn the MacBook off completely.
Some things I've tried to fix the issue include; turning off Bluetooth, deleting the WiFi connection, forgetting the WiFi network, resetting the router, changing the security settings of the router and switching off all other devices in case one is causing a conflict.
I'm baffled!
Has anyone experienced this? Any other suggested fixes?
Thanks,
Kevin

OK, so I've finally solved the issue (after a couple of months!) - tonight I stumbled across this post: https://discussions.apple.com/thread/3733629?start=0&tstart=0
Disabling photo streaming and then resetting the router has done the trick!

Added a password to my wifi network...now connection is slow as death

It was fine yesterday. I added a password to my wifi network, which was open previously. I also updated the firmware.
I can successfully connect an iPad and 2 macbooks to the wireless network with NO problems.
BUT... My iMac sees the connection no problem, but cannot load a page. It will start to load, maybe catch a few lines of text, and then the status wheel just spins and spins and spins until it times out. This happens in Safari and Firefox.
I have removed the password and it's fine again. What is it about the password that makes my computer not able to connect?
Any help appreciated....Thanks....
--Derrick

Then try this. Open System Preferences->Network pane and click on your current connection (under Airport) and then turn off the Airport card. Then at the top of the pane you will see the "location" drop-down. Use that drop-down to create a new "Custom Location". Don't worry, it will act actually like 'Automatic'. Then after making the new Custom Location look at the bottom of the Network pane for the 'Apply' button. Click on this to save your new Location. Then rejoin your wireless network again. See if this helps, Good Luck.

Can there be a hardware issue on the iPad that causes you to unable to join wifi networks or only if you are within 5 feet of routers?

I used to be able to connect my iPad to my house wifi network walking all over my house then one day it stopped. When i tried to connect to my network I would get an message saying "Unable to Join network". I found that if i was within 5 feet of my router it would connect and work just fine. At the same time I tried it at multiple other networks that I have before (girlfriends and other friends houses) and could not connect with same issue. Only place I can connect is my work wifi.

How do I check a wifi network on my iphone 4S ?

I was in a Dennys restaurant that boasts a free WI-FI network, but couldnt logon to it. The iPhone saw the net but would not join it. No-one else could get onto the network either. This has happened in other locations too.
My home network is via the Telus phone line. I noticed that on this network, according to Speedtest.net, the internet speed is not very good, i.e. download 5.96 MB, Up 0.43 Mb/s, ping 62ms
Thanks for any ideas on making it easier to join free networks that wont be joined, and speed up access on a slow networks

If others are having problems getting on the network, it's probably a problem on the network, but I think you understand that. If the network is broken and it doesn't belong to you, the only way to 'bypass this' is to disconnect from the WiFi network and use 3G. That or complain to the manager... I doubt that will do you much good. They can barely figure out how to fry eggs, much less do anything with their network.

Slow to no wifi speed on 4s after ios 6 update

yesterday I updated my 4S to IOS 6 and now my wifi speed is zero. I've restored the phone, deleted the wifi network and rebooted everything and I still cannot even complete a speed test on the phone, it's so slow. It will not pull up a map or download an upgrade.

I, too, had slow WiFi connections when able to connect at all after upgrading my 3rd generation iPad to IOS 6. I think I found a way around the problem this morning and have notified my Apple support contact with my findings.
The following provides a little background about my specific problem:
After upgrade to IOS 6, home network wouldn't connect
Tried all the suggested options (recovering iPad- twice, Auto proxy, turning wireless and airplane mode on/off, rebooting iPad, disabling wireless security) none of which solved problem
finally able to connect by reconfiguring my Linksys E1500 router to use channel 6, confusing because it use to work, but at least I was connected
In my office I had great connectivity with no modifications - ran speedtest and had >18Mbps/sec download speed
Figured it was my router so was getting ready to buy an AirPort, when I found that my Mac-mini could be configured to operate as a router
Configured the Mac to share my ethernet and got excellent connectivity on iPad >18Mbps/sec, same as in the office
Tried all Linksys router channels and found could only connect on channels 6, 7 and 8 and only when channel width was set to 20Meg. Could only connect using 20/40Meg channel width on channel 6.
Throughput on channel 6 was: 0.72Mbps down, 1.05Mbps up with a ping time of 156Msec (Note router was in N/B/G or "Mixed" mode)
Reconfigured the Linksys router to only use B/G mode and the Auto channel selection now works and got the following throughput: 6.79Mbps down, 3.30Mbps up and 975Msec ping (Note this was about 50 feet from the router - same conditions as above. When in the same room as the router got: 19.58Mbps down, 3.38Mbps up, 982Msec ping)
So for my specific problem I could acheive acceptable WiFi performance by downgrading my LinkSys router to not use "N" mode. Since N mode works between the iPad and the Mac I suspect there could be an issue with Apple's implementation of the protocol, but I've supplied this information to Apple in the hopes they can address my issue in their next patch release.
I hope this information is useful to others.

New Ipad mini will not connect automatically to home WiFi network

I use a range of Apple devices at home, IPhone 4, MacBook Pro and IMAC.
They all see and connect automatically to my WiFi home network. I never experienced any difficulty with my DLINK router.
I have received a couple of days ago my new Ipad mini (Wifi+ cellullar), running IOS 602, but not equipped with a SIM card.
The device never connects automatically to the home WiFi network.
I need to open the Settings app, chose the WiFi submenu and select manually my "dlink" network. Then only can I work with my network.
I need to perform this each time I leave my home or I restart the device.
As I am experienced with Apple devices I noticed this behaviour right away and can confirm that the settings on the Ipad mini are the same as the ones of the IPhone 4. I am certain that this is a bug.
Any suggestion to overcome this major frustration?
Patrick

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
