IPhone 4 Connects, but Can't Surf Home Wireless Network

Never had a problem with my 3G, and I'm using the same settings on the 4. Using a Linksys WCG200 wireless cable modem/router on Comcast. BTW, wi-fi works everywhere else. It is just on my home network that I'm having a problem.
I've rebooted the router, re-set the network settings on the phone,added the phone to the DMZ Zone on the router, added the MAC address to the wireless access filter, disabled the wireless access filter when that didn't work...
I can connect to the wireless router just fine, and show up as connected in the setup screens of the router, but can't access any web sites, or use any apps (app store, etc.) that require connectivity.
I don't have enough hair to be able to afford what I'm pulling out right now. It seems to me that I've covered all the bases. Am I missing anything? What is my next step?

I have the exact same router as you, I have Comcast, and I am having the exact same INFURIATING problem.
Comcast and Apple have no ideas. Linksys tells me I am having a router problem.
I even went so far as to buy a new router and modem from Linksys (as they claim they no longer make the router/modem combo because it doesn't work well). I still don't buy this... my PC, my PS3, my DS... all of them connect to the router perfectly.
I have the new modem and router here and planned to give that a whirl tonight but Comcast was being difficult and saying it could take 72 hours to activate my new modem. Totally unsat. I had them reconnect the WCG200 and I am still trouble shooting to no avail...
If anyone finds a fix (short of a new router and new modem)... please post!

HT4259 I have a Netgear wndr3400 and I can "join a wireless network" but can not "extend a wireless network" on my Airport express. Does anyone know why?

I have a Netgear wndr3400 and I can "join a wireless network" but can not "extend a wireless network" on my Airport express. Does anyone know why?

Sorry, but "Extend a wireless network" is a proprietary Apple setting that will only work if you have another Apple router.
It is not compatible with devices from other manufacturers.

MacBook Pro Can't find home wireless network

I've been having some issues getting my macbook pro, running OS 10.7.5, to find my home wireless network. The network doesn't show up when it searches automatically, and when I type the network name in to find it manually, it says no network found. The computer connects to all other networks and finds then with no issues, and other MacBooks are able to find my home network and connect to it again with no issues.
The computer used to be able to find the network, and then it just stopped working. I have tried all the standard fixes, resetting the router, computer, PRAM, forgetting the network, deleting the key from keychain, but nothing seems to work. I tried googling the issue, but wasn't able to find a problem similar to the one I have.
Any advice would be greatly appreciated.
Thanks

Still having problems with this.
I have upgraded to Mavericks, hoping that the problem would be fixed, but it hasn't. I still get all networks completely disappearing - even if I search for them they are not found.
But I reboot the computer and it works! But when I am in OS or Bootcamp mode and put the Mac to sleep, it does not see the networks again! I have to reboot the computer for it to work.
I have even got a new router which can receive the b,g and n signals etc. as I was told by a Mac techie here that Macs 'look' for the n signal but can also work with the b and g signals and THAT maybe my old router only transmits b and g or something like that .
This, to me, sounds like a Mac software problem. I had a similar problem on a previous Mac on my "old router" and a totally different router in a different country's telephone system.
I now have the same problem with a new MBP on a new router!

MacBook Pro only can't find home wireless network

Hey guys!
I purchased a 15" retina MacBook Pro by July. It brought Mac OS X Lion with it: I had no problems.
However, more than a month later I upgraded to Mountain Lion, and I started to have the same problem ALWAYS: sometimes I would be connected to my home wireless network, perfectly fine. However, after shutting down, sleeping, etc, whenever I would turn the Mac on again, it wouldn't find my home network wireless anymore, but it would find e.v.e.r.y and other network available. Also, my phone, iPad, and every other equipment, would find it and work perfectly. After several restarts and wake ups from sleeps, the Mac would eventually magically find it and stay connected for an unpredictable amount of times (sometimes it could find it continuously for some days after some sleeps, and sometimes it wouldn't be found again after some hours of it being found again (assuming the computer went to sleep)). But if I try any other of the available networks it connects with no issue!
And I've been in this game constantly! I've tried (almost) all the Mountain Lion wifi-related posts in the Internet, but none seems to solve it.
I have only found a few posts with my related issue, which I recall: the Mac won't find, ONLY, my home network, while any other equipment can, and it can magically find it occasionally, lasting its connection until the next sleep or shut down.
Help would be really appreciated.
Thank you,
Juan

Hum, good point, the problem may lay with the router compability. My sister, who has ML as original OS has been having the same problem of not finding only our home network, so it seems that the problem lies on Mountain Lion compatibility with the router. I just restarted the router several times and we both got internet at the same time. The question is, as always, how long will it last until it won't find it again.
Now, focusing on the router.
Here, in Portugal (as for the rest of the world I don't know), the Internet provider companeis offer their own modems. Not only that, as those modems are both: modems and routers ( http://imageshack.us/scaled/landing/149/ofibrasjaestaabombar.jpg ).
After writting the above, and re-reading what you said, you lighted me up the idea of entering the modem domain (you know, that url you put and have access to every definiton of the router?)
Well, the password "type" was selected to "WPA and WPA2". What I did was selecting "WPA2" only. So far it seems that it is working. I'll do some restart tests etc etc and I'll let you know! (Maybe the problem may persist, but I'll only know days from know as it may seem, for know, that it is solved.)
I'll let you know, and thanks for the help so far, Sig!

Connected but can not surf to internet with n97wif...

my n97 has no problem using my home wifi to surf the internet.....
i want to try to use it to connect to the wifi from Mcdonald....in Brisbane...
i get the Mcdonald log-in screen and accept the terms and log in OK.....but could not surf the internet....and get the error message....
I have the same situation when I go to the free wifi in Brisbane library....
Can anyone please help

If you are connected, you are connected. What error message do you get? There could be a lot of reasons why surfing fails. Maybe you did'nt order anything and Mac is angry with you.

I have my iPhone connected but can't seem to sync my music to the MacBook music library, what should I do?

How do I sync my music to my Mac? When I disconnect my iPhone, my music library is gone. I've already authorized the computer so I'm not sure what to do next.

Make sure you have the latest iTunes version. Is all the music on the phone or mac? If former there are programs like I iexplorer you can use to add to library. iTunes syncs only from computer to device.

Ipad2 can't find home wireless network

Hi there.
I'm getting reeeeeeeeeeeeeeally frustrated. My ipad2 had no problem finding my home network when I first bought it but I've recently had a problem with my talktalk phone line (it was down over the weekend) and now my ipad can't find my network! My desktop pc is connected and I can connect to the internet no problem. I'm using a Huawei Echolife HG520b wireless router. Even after following talktalk's instructions on-line I've not been able to find my user name/password to try and connect manually.
Can anyone help??

Sing-
Unplug your WiFi router for a few seconds. Then reset the iPad's network. Go to Settings-General-Reset-Reset Network Settings. You will need to reconnect the iPad to WiFi. I'm not sure how you would reset the Kindle, but unplugging the WiFi may solve the problem for it as well.
If the problem continues, see <Troubleshooting WiFi Networks and Connections>.

TS1398 this didn't help me at all. out of the clear clue my iPad can't even scan for wireless networks. even when I type in my home wireless network name. my phone can connect to it but for whatever reason my iPad won't. nothing I've tried works. I'm ****

believe me I've tried EVERTHING and my iPad still 'can't scan for wireless networks'. it happened all of a sudden and is really really frustrating. I really don't want to have to drive 40 minutes to the nearest 'genius bar'. I'm about ready to break this thing over my knee. I've even tried the frig trick. it worked for about 30 seconds. and then? nothing. any non sarcastic suggestions?

I have 2 macs and 2 PC laptops in my home wireless network. Can I use the Airport/Time Capsule hard drive to back up all 4 machines? I know that I will have to use different back up software on the PCs, but is it possible over the wireless network?

I have 2 macs and 2 PC (Windows 7) laptops in my home wireless network. (The iMac is hardwired via ethernet to the Airport/Time Capsule; the others are wireless connections using Airport). I want to use the hard disk drive in the Time Capsule as a network backup drive for all 4 computers. Is this possible? Could someone help me by telling me how to configure it? I know I will have to use different backup software in the 2 Windows 7 Laptops? Do I need to use the Windows backup software, or can I use a third party program like Acronis True Image? Thanks in advance for the help

It is your fault, pondini.. all your fault.
I read of all the things that go wrong restoring Time Machine backups.. particularly stupid things like mail, photo libraries don't go back.. etc. And looking through the incredible number of issues people have here, when their Mac finally takes a dive how hard it is to restore.
I restored a test hard disk from a TC.. and it takes ages and ages to even make up its mind to start.
I worked in computer support for ages, but not Macs.. so my experience is ghost.. ghost images.. on large commercial server setups, can stream restore to multiple computers at once.. even doing it computer by computer the image is simple as network boot to restore. But ghost went the way of Symantec.. sigh!! And was destroyed.
A product like clonezilla, Free linux boot cd.
http://lifehacker.com/5078397/clonezilla-backs-up-and-restores-your-disks
Can backup a Hard disk in just about any format.. yet to try it on a Mac to a TC.. but I will. Boot from CD.. instead of your lost Lion partition which no longer exists (because the hard drive had to be replaced) and the DVD they no longer give you, and restore the entire hard disk in a couple of hours .. to the exact image at the point you made the clone.. in any format, with any partitions.
My bet is that it will kill TM .. but you could be right.
It is just the prospect of all those permission changes, photos and mail libraries etc that worry me.

Suddenly can't connect to home wireless network

All of a sudden I can't connect to my home wireless network - always has worked perfectly. Now I get a box asking for the password, and although I type it in correctly it keeps saying "incorrect password." I thought I'd delete it and re-establish it, but it doesn't show up in the Managed Network settings. Any ideas what is going on?

On the problem computer, go to Control Panel > Printers and delete all instances of the printer.
Next, print a Wireless Network Test from the front of the printer (Network menu). Note the printer's IP address.
1. Make sure the printer is turned on and connected to your network. Verify that you can access the printer's internal web page by browsing to its IP address before continuing.
2. Click >> Start >> Control panel >> Printers.
3. Click the Add a printer
4. Select Local printer
5. Select Create a new port and select Standard TCP/IP Port and click Next button.
6. Under Device type, select TCP/IP Device. Under Hostname or IP address, enter the printer's IP address. Click Next.
7. Select Hewlett-Packard from the list of manufacturers and select and select your printer model. Click Next.
If your printer model was not listed, then select Have Disk, browse the HP CD that came with your printer and select the first file that starts with hp and ends with inf. Click Open then OK. Select your printer model. Click Next.
8. If you are asked, use the currently installed driver.
9. It will ask for the Printer name -- enter a new name or use the existing one. This will be the name of the printer that you select from other applications.
10. You may be asked to share the printer. Choose NO.
11. The Print Test Page box appears. Go ahead and print it.
12. Click Finish.

Help, just had my iphone 3 but can't connect to wifi, i get as far as the password put in the correct password but it won't accept it, any ideas?? Thanks

What type of encryption are you using with your wireless network -WEP or WPA?
If your wireless router supports both which it should unless it is quite old and you are using WEP, try switching to WPA which is much more secure than WEP which is important if you have a Windows PC or any Windows based device connected to your network.
In addition, when was the last time you checked Netgear's website to see if there is a firmware update available for your wireless router model that you haven't installed?

Can't join home wireless on iphone 4s all of a sudden

All of a sudden I can't get join my home wireless network-get message "unable to join belkin..."
It can't be the router because the wireless works on my old 3gs iphone.
I tried the "forget my network" - it prompts me to input password, which I do, but I still get the same "unable to join, etc.
The only change I made this morning was to get the textfree app from itunes, but I can't imagine that disabled wireless.
help! thanks

No. How do you "restart" a router? by resetting it? I don't want to delete my settings unless absolutely necessary
Besides, if it is my router, why does wifi work on my old iphone?

Thanks a lot i followed the instructions for safe mode (i found out that i was pressing the C button after restarting) i did whats written there but the repair couldn't be performed so in addition i needed to re-formate the HD so i erased the volume and then repaired the disk--> quite disk utilities --> start the installation from the installation DVD.
Thanks really appreciating your help

I have an eMac which I want to connect to my home wireless network. My router is D-Link-601 tech 802.11n. My emac is wireless ready but does not contain an airport card. Do I need a card and an airport station? What else?

You need the Airport card OR Airport Express but not both. Considering the age of your machine, I recommend Airport Express as you will find other uses for it whenever you replace the eMac.
To set up the AE, you do need OSX 10.4 or higher.
