My airport extreme (generation 5) was set up using wifi and has worked flawlessly (on macbook pro 2 iphones and window 7 HP pc)until recently. I have reset to factory defaults over and over but still cannot get on the internet. Any suggestions?

My airport extreme (generation 5) was set up using wifi and has worked flawlessly (on macbook pro 2 iphones and window 7 HP pc)until recently. I have reset to factory defaults over and over but still cannot get on the internet. However I can then take my DSL cord and insert it in a different Ethernet port other than the WAN port and I can get internet on my Mac and iphones but only wifi on my husband's PC. I hate to spend another $179 if this is just something I'm doing wrong. Please help

I'm having a bit of trouble confirming that the ZyXEL is a combination modem & wireless-N router. If it is, then you really won't get any advantages of using the 802.11g AirPort.
If the range of your ZyXEL is limited, you may find that doing either or both of the following will help: 1) Move the ZyXEL so that it is higher vs. lower in the room, that is away from any closed areas or placed in a metal cabinet, and 2) Changing radio channels. The latter is especially important in you live in an area where there are a number of competing Wi-Fi.
A good utility to find out, is iStumbler. You would use this to find these other Wi-Fi and find which have the strongest signal value. Those that do, you would also want to note which channel they are operating on, and then, change yours to one that is at least 3-5 channels away. So, for example, if you find strong ones on channels 1 & 6, change yours to 11.

Firefox will not start. Have error message "Failed (unknown reason)". Now I cannot get to the Internet

I was browsing and was asked if I wanted to update Firefox. I clicked yes. Thought it loaded, but now I cannot get to the internet at all. Now when I attempt to open Firefox and click on HELP, it gives me a Downloading Firefox 3.6.7 - but it will not connect.

If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.

Check to make sure cellular data is not disabled in settings. If it's on, try re-setting the phone. If that doesn't fix it, call AT&T.

I cannot use any server therefore I cannot get on the internet. My ipad can get on the internet. I reset my foxfire to default and now i must have messed it u

I cannot get online from foxfire. My wifi is working since i have it on my ipad. is foxfire locked up so it cannot allow me to use a server to get on the internet. there is no connection. when i reset firefox to default maybe it did not set up right.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.

My Ipad2 won't turn off. I've tried the reset method, holding both buttons down for at least 10 seconds, but this doesn't work. I'm on version 5.1.1 and all other functions work except that I cannot get onto the internet via wi-fi either. Help ??

My Ipad2 won't turn off. I have tried the reset method by holding both buttons down for at least 10 seconds, but this doesn't work. I can't get onto the internet via wi-fi either (don't have a 3G card fitted). All other functions seem to be working OK including charging. Not had this problem before, but I recently upgraded software to 5.1.1 so is there a bug in there somewhere?

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.

I have a good connection thru both wifi and ethernet but cannot get to the internet

I have a good connection thru both wifi and ethernet but cannot get to the internet

Which model iMac do you have? Which OS system is currently installed on your comp?

Some devices cannot get on the internet

I'm at end's wits with my network at home. We have a Clear modem with only one antenna to their tower (no internal WiFi), cabled to our Airport Extreme (more than 10 feet away). The Clear modem is annoying and won't let me disable DHCP, so I created a private network with a range of IPs 192.168.1.100 to 200.
Only four devices will get on the internet, the other 2 won't. I can ping from them the router and even an external website but not no browser will work on them.
Any ideas? It's beyond frustrating. Is the Airport limited to 4 devices only? That would seem absurd.
Thanks Nicolas

Cannot connect to the internet - No IP Address

I have seen variations of this problem but nothing that has helped me. I have a Linksys WRT54G Router in my office and connect through a ethernet cable to my Dell computer. My wife has a Dell in her craft room with a USB Adapter that receives the signal with no problem. Her Mac G5 is the problem. Up until last week her built-in Airport Extreme card picked up the signal with no problem. I am using WPA Personal for security. Four days ago she started getting no access to the internet with the "no IP address" response. I have tried everything I have read in these forums that best describes my problem with no results. I would greatly appreciate any help.
My configuration is -- cable modem -- linksys WRT54G router -- airport extreme built-in card. The G5 utility shows airport is connected to the linksys network and that the signal is strong, but no actual connection.
Thinking the linksys was the problem, I went to Best Buy yesterday and bought a Netgear router that said it was Mac compatible, but that didn't help either, so I returned it.
Thanks for looking!!

You have to power-cycle your modem to flash that information down to the TC. Who is your ISP btw?

After hooking up AirPort Extreme, I cannot get on the Internet

Just installed AirPort Extreme. After following instructions and turning power off several times in attempt to reset, I still cannot get back on the Internet. Does anyone have any ideas?

Can you provide information on the make and model number of your modem?

Visual internet connection, but cannot get on the internet? Help:(

Hi people.
My wife bought me an Ipod touch. This is a long time ago, because I cannot use it with my wi-fi connection home. I took it with me to my parents, and it worked without any problems there. I took it with me to my place, and I got the same problems.
It says that I got connection and I have the Wi-fi connection icon, but I'm not connected to the net.
I've tried to connect many times. I've deleted and restarted the thing. I've looked at the IP adress, and it started with 169. I've tried to look at this discussion board, but haven't found any help.
I'm getting quite desperate, and I would like to get some help. Since I am quite a beginner, I would like a simple answer:) But any help will do great.
Thank you

I've looked at the IP adress, and it started with 169.
This means you aren't actually connected to the Internet; only to your router.
An easy first attempt at a fix is to turn your router off and then on again.

I cannot get on the internet through Ethernet

Hi Everyone,
I am 100% new to macs, I just purchased a mini used from someone and I have tried to set up the internet through ethernet card and it will not work. I have researched for two days now and there doesn't seem to be an answer. I have done it all using DHCP to try to automatically get the settings but it is bringing up 169 IP address is is wrong. I have tried manually entering the information in and no luck. It is connected straight from the modem there is no router. I am usually good with PC's and could fix everything but right now I am stumped. I am running Mac OS X v10.4 Tiger. I thought I would try this out to see if anyone could help.
Thank you in advance

OK, If they are not using fixed IP addresses, then you should be using THEIR Router. You should get your IP Address through DHCP from their Router. \[As an aside, there can be quite a large cascade of Routers -- yours plus theirs.]
The 169.254.xxx.yyy address is the "self-assigned" address used by your Mac when no one responds to its initial broadcast of a request for assignment of an IP address. This is a complicated way of saying "no one will talk to you".
One thing to check for before declaring their box dead is the lights when the cables are plugged in. No lights sometimes means you are using a cross cable where a straight cable is required or the reverse. Most modern Macs "sniff" the cable and adjust to use whatever cable is provided, but older Macs do not.
Some providers grab the first M.A.C. Address (Hardware Address) they see, and limit connection to only that device, ever. So if your computer dies and you get a new one, you have to call them up and ask them to reset their box. Sometimes there is a procedure for a "Deep" reset in their manuals, and you may need to apply that now. \[and if you decide to add your own Router later, you call them and tell them you are installing a different "computer". Your Router then becomes the only registered device.]

Cannot get on the internet

I received a new iPad 2 for Christmas and I set it up at the Apple Store tonight...
but when I got home, I could not connect to the internet because I cannot remember
my wi-fi password. Any ideas on what I should do?

My hard drive was just replaced and cannot get on the internet

My hard drive was just replaced and my computer is showing connected to the internet but when I put a web address in it shows unable to connect.
Any advice?

Restart the router and the broadband device, if they're separate. Any change?
