Problems with wifi after 4.3

Upgraded to 4.3 on both my iPad and iPhone 4. After the update neither can connect to my dlink dir655 set only to wireless n. They both can connect to my verizon westell modem/router perfectly fine which is g. I have reset router and iOS devices. No clue what's wrong. Anyone else see anything similar or have an idea on a solution.
update: If I drop the dlink router to wireless g they both connect fine. and FWIW my mabook pro can connect to the dlink at either n or g.

Same here... but in my case nothing worked (restarting router, checked firmware.. it is latest from Netgear.. resetting network connection etc.).. I get very slow speed wifi connection (with the speed test 0.3 Mbps down and 0.2 upload).. Just before update it was 9Mbps upload and 1.4 download. This is total shame on Apple. They call their products are top of the line but I have many wifi devices never experienced such a crappy performance Apple testing needs some fundamental training to validate some basic functions before releasing the OS to the users. This is total shame and I am forced to use 3G even at home (I am sure I will max my 2GB limit). I am requesting tech support with the GREAT GENIUS people in Apple store and will ask for refund for any overage which I am going to pay because of this crappy upgrade with a major bug Apple exposed to its valuable customers.

My problems with WiFi after 10.5.8 update (and how I solved them)

Hi, I also had problems getting online after last Leopard update. First I tried to delete all network related preferences (as posted here http://discussions.apple.com/message.jspa?messageID=9965959#9965959) but soon the problem reappeared.
I need to connect to 2 different routers, one at home and another at the office. After doing what I said in my previous post (see above), I managed to connect to one OR the other, but not both. I had to delete my home config when I was at the office, and the other way around at home. (i.e. I only could connect when only ONE network was configured in Airport preferred networks).
After some trying, I realized both of my router had their SSID hidden. I then broadcasted my home router SSID and, voilà, everything's fine.
Hope this will help some of you getting around this nasty bug.
Regards.

Had issues with my WiFi router too, after upgrading my MacBook Pro 13" to 10.5.8. Not sure we're talking about the same issues, but my MacBook connected to my WiFi network, had also a IP address, but couldn't connect to any host, nor on the local network neither outside.
After reading your post I tried to remove the network completely from the list of known networks and to set it up from scratch. Seems it works now...
Thanks,
Thomas

Ipad mini problem with wifi after update 6.1.3

Hello!
My ipad mini was working fine before the 6.1.3 upgrade, immediately after updating, the wifi stopped working. Restore the iPad to its factory settings as deleting both my data and to reintroduce the network, was still not working.
Help please!

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Some other things to try:
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

Problems with wifi after lion upgrade 10.7.2 but only at home

HI, my wifi conection was problemless till I upgraded to lion 10.7.2. After that, it is impossible to connect through airport but only in my home´s wifi. Other computers work at home (including my iphone) and my macbook pro connects everywhere else with no problem but it doesn´t at home. Inmediately after choosing the desired conection it says: Not posible to conect due to conection time run out (or something like that).
Any help?

Then it would appear to be an issue with your router. What router? Model? Is the firmware up to date?

Problems with WiFi after upgrade

I have an Ipod Touch 16gig second generation. I recently Upgraded to version 3.1.2(7D11). After the update my WiFi does not seem as stable and I cannot connect to networks in locations that I once could. Even in my home network the signal strength appears way lower than before the update. Is anyone else having this problem? Is it something I did wrong and is there something I can do to try to rememdy this? Thanks for any input.

I have a 2nd gen touch. Last week I finally updated it to 3.1.2, and, along with my touch, updated my lap to the newest itunes and safari. Before, with the old software (I've been overseas since April so I adn't updated my pod for a very long time) my ipod could easily find unlocked wifi and join onto the network. It was great on the net. I used a wifi finder app that was fantastic. Now? My app doesn't open, itunes refuses to update any of my apps and my touch shows it has wifi but won't go online.
I've done everything recommended; reset all settings, reset network settings, restored...you name it. Still nothing. I'm so frustrated. If I had known that this would happen, I would never had updated. Leave well enough alone. I only updated because all of the new game apps wouldn't be supported by my software. I wanted to play Sims 3. Irony is, now that's all I can do on my touch now.
Advice from anyone? Lord knows I can't go to apple itself. My warranty is up and unless i pay, they won't help.
Gee, think they'll start noticing that there's a fair amount of people having the same problem and maybe, just maybe, they should fix the bug...and not charge for it!! Angers me even more. I had to pay money for software that made my podly sick.

Having problem with wifi after upgrading to iOS 6

After I upgrade my iPhone to ios6 I am having many problems connecting to wifi.
Places that I had wifi connection at home now are not available and it takes long time for the iPhone to connect to the wifi.
What to do??????

Do the basics first. follow http://support.apple.com/kb/TS1398. I would also clear cookies and data in settings > safari.

Problems with wifi after iOS4 update

Hi guys well I have an iPhone 3Gs currently running 4.1 but came with 3.1.3. The wifi at home works fine and that is WEP secured the only problem is the schools network. In order to connect through wifi you need to use Manual Proxy Settings with the following settings
Server: 10.1.0.12
Port: 8080
Username: ELTHAM\<username>
Password: <password>
Everything worked fine on 3.1.3 and it ALWAYS connected. Now the settings say it's connected but there is no wifi simbol only 3G, and if I turn data off while connected to wifi safari says its not connected. I have tried restoreing, setting up as new iPhone, reset network settings but no luck whatsoever.
Does anyone know why this is happening?

Yes, an all of a sudden it started working while sitting for around 30 minutes, shouldn't take that long

Problem with Wifi after upgrade to WIN10

I have Idea Center B300 AIO desktop with RTL 8192 Wireless adaptor. Wifi is not working after I upgrade to WIN10 yesterday. I am not getting WIN 10 beta drivers also on URL http://support.lenovo.com/us/en/downloads/ds102364 but could not get for my desktop.

hi pramodlele,
If you look under Device Manager > Other Devices, do you see a Network Controller entry?
If yes, have you considered installing the Win7 driver and running it in compatibility mode?
Wireless LAN Driver - Windows 7 (32-bit, 64-bit)
RTL8192SE and Windows 7 Drivers
Alternatively, you can also right click on the Network Controller > choose Update driver software > Search automatically for updated driver software and observe.
Let me know how it goes.
Regards

Problem with WiFi after installing Windows 7

Hi, i am using a Mac book White(newer model) and recently installed Windows 7 Professional(x86). When running windows 7, the WiFi is not working, meaning that it does not even detect any wireless connections when there are like more than 10 in my area. However, when running the Mac OS, i can connect to my home connection and view the rest of the connections. Now i am being forced to use the wired connection every time i wan to use the internet using the windows 7 OS. I troubleshooted, and they asked me to update my driver. But still it is not working.
Is there a solution to my problem, it is greatly appreciated
Message was edited by: AppleUser2310

I had the same problem last night. Boot into OSX and reboot the router - fine. Boot into Windows and wrong. Here were my fixes:
Firstly, I kept all the settings on my router solid. Just leave them as they are. Boot into OSX and check the Network settings and make a note of your IP address and the router's IP address.
Second, boot into Windows, then open up your wireless connection settings and navigate through to the properties where you can set the IP address.
Third: Set the IP address to your routers IP address changing the last set of digits to a value between 5 and 255 (I have 8 devices so I set the last two digits to 10.) This will keep the IP static.
Tab through the Mask settings to default those.
Then set the default gateway to your router's IP address.
Check that the Network Adapter's setting has IPv6 disabled (uncheck the box)
Finally: Set the primary DNS server to 8.8.8.8 then the secondary to 8.8.4.4 and then reboot the router.
That's what got my connection running.

Dear Apple. I have no wifi signal after last update. No result after reset or etc. only after 5 min cooling of my iphone 4s ( thanks for recommendation from apple store team) in refrigerator)) it's not funny.

Also try:

You'll have to re-enter any WiFi passwords.

Problems with WiFi network connectivity post 2.1 upgrade

Have been having problems with WiFi connectivity since installing the 2.1 upgrade. When attempting to view some websites I get a "Safari cannot open the page because it is not connected to the internet" message. The same addresses can be resolved from my iMac at the the same time. Other websites don't have problems. Funnily enough www.apple.com is one of the effected sites.
I can also only sporadically gain access to the App store & the iTunes store from the device. I mostly get a message stating - "Cannot connect to iTunes store".
I am connecting through a WPA encrypted access point. I have tried restoring the device, resetting network settings, etc.
Has anyone else experienced this? After work tonight I will temporarily set my access point to WEP, just to see if the problem may be related to WPA. I have read that the iPod touch is effected by this.
Thanks,
Matt

No problem. The iPhone uses lower power on the WiFi transceiver to save the battery. It won't have the 50 meter range that one might see for other devices. As long as it works reliably when it is closer to the access point it is working normally.

Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please.

Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please. I've already tried a lot of your suggested fixes, but without success. Why hasn't Apple Fixed this?

Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 6
In the Wi-Fi settings, select
Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local
Click OK and then Apply.
Step 7
Reset the System Management Controller.
Step 8
Reset the PRAM.
Step 9
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 10
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
