Why does wireless hang up even with strong signal?

Using airport extreme. iMac shows all bars (strongest signal), but often seems to get stuck when web surfing. Any thoughts?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

I get a weak signal with WIFI or 3G on, but a strong signal with EDGE.HELP

I get a weak signal with WIFI or 3G on, but a strong signal with EDGE. This doesn't make any sense! Help!

this happens to me, too. i get 1 bar of 3g but 4-5 when it switches to edge.
i also got this on my old blackjack ii and thought maybe it was just something having to do with that phone, but i guess not!

Which has stronger signal: WMP300N or WUSB300N ?

I have been looking over the data sheets for these two Linksys wireless 802.11n Draft 2.0 cards, and am wondering if one has a better signal strength range than the other?
WMP300N is the PCI version of the adapter and here is what is listed for it from the SPEC sheet:
Transmitted Power 802.11g: 12±1dBm (Typical); Wireless-N: 10±1dBm (Typical)
Receive Sensitivity 54Mbps @ -70dBm (Typical); Wireless-N @ -70dBm (Typical)
WUSB300N is the USB version of the adapter and here is what is listed for it from the SPEC sheet:
RF Pwr (EIRP) in dBm 802.11b: 14±1dBm (Typical)
802.11g: 14±1dBm (Typical)
Wireless-N: 14±1dBm (Typical)
Receive Sensitivity in dBm 11Mbps @ -86dBm (Typical)
54Mbps @ -68dBm (Typical)
Wireless-N @ -62dBm (Typical)
So, is there any difference?

As per my knowledge the WMP300N adapter is better that WUSB300N ....as the adapter is having better receiving ability ....... also the usb adapter is more exposed to hardware failure ......

My iphone 5 is showing the network and 3G logos but has no signal bars and I cannot make or receive calls or use the internet

Hi,
I recently bought my iPhone5 second hand off a friend. Having inserted my sim the O2 network logo and 3G symbols appear in the top left although there is no signal registered. I am also unable to make or receive calls as well as use the mobile internet.
The phone is registered to O2 so there is no network clash
THanks

Hello denman1991,
It sounds like your phone is not connecting to the cellular provider network, and you are also unable to connect to the Wi-Fi network. I would recommend these troubleshooting steps from the article named:
iPhone: Troubleshooting issues making or receiving calls
https://support.apple.com/kb/TS3406
Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.
Check your phone settings:
Check your Do Not Disturb settings: Tap Settings > Do Not Disturb.
Check for any blocked phone numbers: Tap Settings > Phone > Blocked.
See if Call Forwarding is turned on: Tap Settings > Phone > Call Forwarding.
Ensure that your software is up to date:
Check for a carrier settings update.
Check for an iOS software update.
Note: Some updates may require a Wi-Fi connection.
If the iPhone has a SIM card, reseat the SIM card.
If the iPhone 4 or iPhone 4s is on the Verizon network, dial *228 from the iPhone and select option 2 to update the Preferred Roaming List (PRL). The PRL determines the cellular towers the phone uses for cellular service, selecting those with the best signal strength.
Reset the network settings: Tap Settings > General > Reset > Reset Network Settings.
Try to make or receive calls in another location.
Attempt to isolate to one network band:
If you're having the issue on LTE, disable LTE, if possible, and try again.
If you're having the issue on 3G/4G, disable 3G/4G, if possible, and try again.
Contact the carrier to check the following:
Your account is properly configured to use the specific iPhone that has the issue.
There are no localized service outages.
Your account doesn't have a billing-related block.
Your calls don't have errors on the carrier system.
Restore the phone as new.
Also, for your Wi-Fi network issues, I would recommend this article named:

VGA Display Detected But Has No Signal

Hello,
Here's the issue,
I'm working on a 13" MacbookPro 10.8. I plug in mac's "display port > VGA" adapter to display my second screen on projectors for a power point presentation. The Mac flashes the screen like it recognizes the display and when I go into the display settings it gives me the second screen options just as it should. However, the desplay remains black as if nothing was ever plugged in. I did the exact same thing on my personal computer which is a 15" MacbookPro 10.8.4 and the projector works fine ruling out any issues with the gear. I've gone to several forums and tried all of the "unplug this, turn this on, wait 15.5 seconds." tricks that people say to do but to no avail. I'm going to try to update the system to 10.8.4 and see if that works, just waiting on passwords since it is a work computer.
Any Ideas?
- Josh

It was the update! I guess 10.8 had some issues with the projector but all is well with 10.8.4

My SD card is not recognized by my iMac, it worked before, but has stopped working, Mac OS X Lion 10.7.5

Any ideas?
The card is a SanDisk SDHC 8GB

I just blew into the slot and it worked again, issue resolved

The wireless symbol is present and indicates a strong signal, but I can not connect to the Internet.

The wireless symbol is present and indicates a strong signal, but I can not connect to the Internet. I'm on my home network and have never had trouble before. My iPad is current on all updates. I have tried to reset the network settings, nothing has worked. I can connect to the internet via my iPhone personal hotspot and all other wireless devices are operating normally on my home wireless network.

I am also having this issue. My boy just got an iPod 4 touch, upgraded to iOS 6. I have a D-Link DGL-4300 108G Wireless Gaming Router. With the iPod I can connect to the router, get an IP address (either DHCP or Static) and even browse through the menu on the router, but I can't connect to the internet.
With a DHCP IP address the iPod give the error "Not connected to the internet" with the static IP address it takes a long time when trying to connect to a website but then it gives the error "server stopped responding".
Clearly the issue is in some setting in the router. I've tried setting up a filter so that the iPod will always have access based on MAC address. I've tried changing the various wireless connection settings, all to no avail. I would greatly appreciate some guidence here.

Airport Express gives out strong signal and IP address, but no Internet

I'm trying to solve an Airport problem for a friend who has an Airport Extreme (802.11g) and an Airport Express. The base station is connected to a cable modem. The Airport Express is used in WDS mode to extend the wireless network. There are two computers involved: a MacBook Pro and a Dell with Windows XP. The Airport Express is needed to extend the signal into the room where the Dell is located.
It had been working fine but stopped working and went into "flashing orange light" mode. I tried hard reset but that didn't help; I had to reset it to factory defaults to get it to even respond to the Airport utility.
After the reset, and after reconfiguring the Airport Express, the Airport Express cannot provide Internet access wirelessly. Here are the specific symptoms:
(a) Computers in the vicinity of the base station (both my friend's MacBook Pro and my own MacBook) can get wireless internet access
(b) The Dell detects a strong signal from the Airport Express (which is only about two feet away from the Dell's USB WiFi adapter) and gets an IP address from it, but no Internet access
(c) My own MacBook, when next to the Dell PC, also detects a strong signal from the Airport Express, but also cannot connect to the Internet
(d) If I connect my MacBook to the Airport Express with an ethernet cable, I can access the Internet
I have tried both with and without wireless encryption and it makes no difference: no wireless Internet access from the Airport Express.
Is this a configuration issue or is it a hardware problem with the Airport Express?

You are going to have to give us more information. How were your iMac and iPhones getting internet access before the AirPort Express? How was your equipment wired up before, and how is it wired up now?

I am trying to connect to my friend's wifi, i have a very strong signal indicated on my ipad, but cannot connect to the internet. Yesterday i connected without any problem, can anybody tell me why i cannot connect today?

i am trying to connect to my friend's wifi, i have a very strong signal indicated on my ipad, but cannot connect to the internet. Yesterday i connected without any problem, can anybody tell me why i cannot connect today?

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

AccessPoint strong signal but little or no connectivity

I'm having trouble with our wireless access point. We use Cisco 1100. For starters, when you connect, you get a strong signal but little or no connectivity. Any advice?
Thanks,
DJ

If by "Little or No Connectivity" you are talking about a Microsoft balloon in the lower right corner of your screen, that is telling you that you are connected, but it didn't get a DHCP address, it's using the APIPA 169.254.x.x.
Verify that you can get to the DHCP server, and that it is responding correctly.
As a quick test, assign an IP address (mask, default gateway, DNS) manually and see if it makes a difference for you.
Good Luck
Scott

Why does my sony tv pick up my apple tv but my new LG has no signal from the HDMI input?

Hi midknightsurfer,
Welcome to the Sony Community!
Please try the following troubleshooting steps.
Check for a firmware update for your router.
Make sure the router is broadcasting the Service Set Identifier < SSID >.
Please try other device/s. Connect them to your network (wired/wireless) then test those units.

WRT610N Woes - strong signal but dropping internet

So I've had a WRT610N since June 2011 - working flawlessly without having to think about it at all, I just plugged it in and it's been on default settings and never gave us any trouble.
About a week ago the power went out - and it caused the router to reset itself to factory settings. I set it back up with our network name and security and didn't think much of it. After that, we started noticing issues on our phones and the laptop in the kitchen.
I work in the same room as the router, on wifi, and have not had the signal drop once since then - my work laptop is about 3-4 feet from the router. Another PC hard-wired through the router works fine
Streaming over the 5GHz band to the tv, one room over, works flawlessly, as does netflix/youtube/etc on the TV.
Once you get to the kitchen, on the laptop in there (which has been there for months without issue), the wifi is totally flaky. This is maybe 40 feet from the router, through only 1 wall. The signal reports 3-4 bars, and windows always reports 'internet access' for the status of the connection, but the connection regularly drops and you must manually disconnect and reconnect to wifi to regain internet access. It is the same story with phones if you are more than about 20 feet from the router - they have a strong signal, but will regularly drop, requiring you to disconnect and reconnect. Both the 2.4 GHz and 5 GHz bands appear to be behaving the same way.
Normally, I would just say the power outage fried the thing and get a new one - but it is working flawlessly at short range, and still giving a strong signal at longer range - just not keeping the internet up.
I've factory reset it multiple times since this started happening. I've tried different settings on both bands, different security, no security, etc. But nothing seems to be helping, which is why I'm posting here - help!
Thank you for reading.
Solved!
Go to Solution.

2 days in and no issues yet - I think we can call this resolved for now.
Thank you so, so much!

May iMac (OS 10.7.4) has suddenly stopped printing to my Epson CX4800 printer through Airport Extreme, though my MacBook (OS 10.5.8) continues to function just fine). The iMac will print if it is connected to the printer directly via USB. The iMac continues to connect to the Internet wirelessly. I've tried resetting the printer and ensuring the driver is up to date, but no joy.
Any suggestions?
