Imac cannot connect to with wifi, cannot connect with ethernet

Just purchased this imac last night, and immediatly unable to connect to wifi, very discouraging.
Each time I try to connect to my network with my imac, I recieve error messages "unable to connect" However, I am still able to connect with my macbook pro, and iphone 3gs.
I have tried cycling whole system, unplugging imac, resetting p-ram, resetting modems, and even tried plugging in ethernet directly into imac and turning off wifi but no luck.
its a 27" imac, 3.4 intel i7 8gb ram Lion 10.7

Iphone4 wont connect to home wifi connects to neighbors..others iphones ipads connect to this wifi cannot change it and cannot access apps store. Does nor request password just "cannot access"

Iphone 4 wont connect to home wifi but connects to neighbors open wifi. Family members with iphones can connect to the wifi automatically and Mac compiuter in home connects to this wifi and this iphone did connect automaticcally until a few weeks ago. Does not request password when try to connect to own wifi..just says "cant access.". Also cant access the Apple apps store to purchase apps but all other function operate normally. Apple store tech says nothing wrong with phone. It connected to their wifi and coud access apps store from their wifi. This iphone belongs to son who is autistic. I am mother trying to resolve this issue and very frustrated. Have reset router but no change.

Based on the symptoms, your phone is fine, and the Router is the problem. Try http://support.apple.com/kb/TS1398. Specifically the "forget this network" step. I would also consider resetting the wifi network password. Sometimes that will allow a connection.

My ipod 4G won't connect to my wifi at home with new router. Says "unable to connect" and won't give me any other options. Have tried resetting network connections. Help.

My ipod 4G won't connect to my wifi at home with new router. Says "unable to connect" and won't give me any other options. Have tried resetting network connections. I don't want to lose anything. I have tried turning everything off and back on again. Desktop and laptop are working fine. Sometimes it turns on suddenly and I can use it for like 20 mins but then shuts off again. Same thing is happening with my dad's iphone, Help.

Does the iOS device connect to other networks?
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

• WiFi, Internet problems, possible solutions

IPad cannot acess to Internet, wifi shows connected

Wifi shows connected, and my computer and iPhone can access to the Internet , however, I cannot open any web pages with iPad, it happened once before. I reset the network settings to factory set, still not working.

You may not really be connected to your WiFi network.
Your router may not have given your iPad a valid IP address. Go to Settings > Wifi > your network name and touch the ">" to the right to see the network details. If the IP address starts with 169 or is blank then your router didn't provide an IP address and you won't be able to access the Internet.
Sometimes the fix can be as simple as restarting your router (remove power for 30 seconds and restart). Next, reset network settings on your iPad (Settings > General > Reset > Reset network settings) and then attempt to connect. In other cases it might be necessary to update the router's firmware with the latest from the manufacturer's support web pages.
If you need more help please give more details on your network, i.e., your router make, model and version, the wifi security being used (WEP, WPA, WPA2), etc.

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.

Connection to the internet is working better with wifi instead of wired ethernet?

recently started having a issue of connecting via hardwired cable modem through my ethernet port. modem is working since I also have wifi off of the same box... is it possible to do a self test of my ethernet card? Card is a Marvell Yukon Gigabit Adapter 88E8055 Singleport Copper SA

CDMA vs. GSM: What's the Difference? | News & Opinion | PCMag ...
Code division multiple access - Wikipedia, the free encyclopedia
It is the protocol used for most all US cellular service. GSM is the protocol used in Europe. Unless there is a cellular provider in England that can provide CDMA service and is a partner with whomever provides your cell service in the US, then you would not be able to use your cellular capability. This has no effect on your other wireless.

IPhone can't connect to my wifi, can connect to others. My other devices are fine. Basic T-shooting steps fail.

Sorry for the repeat post but I want to get more help with this.
Prior to problem: All devices surfing wirelessly on Airport Express.
Replaced Airport Express with Time Capsule.
Problem: Wife's iPhone4 (5.1.1) can not surf on wifi provided by my time capsule. All my other devices (iMac, Mac Air, iPad and my iPhone) can. Wife's iPhone can surf on an unsecure network somewhere nearby in my apartment complex. (Which to me, rules out a hardware problem).
Steps taken: Tapped iPhone wifi On/Off multiple times with no change. "Forget this network" multiple times with no change. Reset iPhone Network Settings multiple times with no change. Restored iPhone using iTunes as New iPhone once with no change. (Since doing that, I have restored with back up of iPhone settings and data.) Powered Time Capsule on/off several times with no change. Turned wireless security off with no change. Security is back on. It is WPA 2 Personal with a lengthy password. I'm not getting the "incorrect password" msg. Renewed lease multiple times with no change.
Other indications: 3G is in upper left. Status wheel is spinning next to my network's name. On the initial "Settings" window, my network name is shown (as if it were connected. But tapping it and going to the "wifi networks" window shows the list of available networks with the status wheel spinning next to mine.) Tapping the blue arrow on my network name leads to the window that has "forget this network" at the top, and a list of blank fields: IP address, subnet mask, router and so on. DHCP is chosen, HTTP proxy is OFF. Sometimes, the top two fields (ip address and subnet mask) have values filled in, but the rest of the fields don't.
On my Time Capsule, as seen via Airport Utility (V5.5.3), 3 devices are shown as connected. Clicking this provides a listing. My wife's iPhone wi-fi address is listed. It's "rate" however is 1. My imac is 216 and my iphone is 65. BTW, iOS devices drop off the list when they go to sleep. No big deal there.
Back to Airport Utility, in the summary tab... status is normal, version is 7.6.1, wireless mode is "create a wireless network", security is "wpa/wpa2 personal", channel is 149 auto and 1 auto (I tried changing 1 to 11 with no change), connect using "ethernet" and finally my IP address begings with 76. 76.xxx.xxx.xxx
Moving to the "Wireless" tab of Airport utility... wireless mode is "create a wireless network", radio mode is auto, radio ch. selection is auto, wireless security is wpa/wpa2 personal, "remember password in keychain" is checked. Now Clicking on the "wireless network options" button..... 5ghz is not checked, country is USA, multicast rate is "low", t-mit power is "100%", WPA group key timeout is 1 day (it used to be 1 hour but this has made no change in the problem), "use wide channels" is not checked, "create a closed network" is not checked.
MAC access control is not enabled. But it was enabled previously and I added my devices by their Wi-Fi addresses one at a time until i decided to turn it off due to this problem. this resulted in no change with the problem.
Personally, I feel the prob lies with the DHCP and ip address and related fields, but I don't know enough about what their values should be in relation to my other devices to alter them on my own.

I pasted below a response that helped.... sort of. I followed the directions below. At the end, all my devices were connected to my network. BUT, the last device I connected, my MacAir, did not stay connected for long. It now has the exclamation point in the middle of the wi-fi icon in the top right of the screen.
This event agrees with my original problem: It was my wife's iPhone that was the last to be connected to my network and the only one to fail to connect.
Is there a limit to how many devices can be connected to my time capsule? I have 5 devices. What is "extending?" Do I need to do that?

This solved my questionRe: Airport Express wifi network not working
Mar 1, 2012 1:46 PM (in response to Don_McCracken)
Open AirPort Utility and click Manual Setup
Click the Internet icon, then click the Internet Connection tab
Make sure that the setting for Connection Sharing = Off (Bridge Mode)
Update to save any changes
Then power down the entire network...all devices....power down order is not important
Wait a few minutes
Power up the modem/router first and let it run a full minute by itself
Power up the Express the same way
Continue powering up devices one at a time the same way until everything is powered back up
You should be able to connect through the Express and on to the Internet

Problmes with wifi turn off with disable greyish in window 8.1 pro 9600

Hi,
I updated window 8 to window 8.1 pro build 9600 version.
I am getting a problem with WIFI turn off disable grayish color which cannot be enabled.
WIFI adapter is installed and working properly.
Plz suggest what will be the fix of this issue.
Thanks.

Hi,
Did you mean the Adapter is greyed out and we cannot click to turn on it? Is there a wifi switch on your laptop? If so, please turn on it first.
Also please try the network troubleshooter to see if the issue can be fixed:
1) Right Click network icon in taskbar and select "open network and sharing center"
2) Highlight wifi connection then at top click "Diagnose this connection"
The troubleshooter will discover that the WiFi connection is turned off and offer a "Apply fix" option click that and windows will enable the wifi connection.
To make sure the driver for Network adapter is the right one, please go to manufacturer’s website to see if there is the one compatible with Windows 8.1.
If not, we can try to install the one applied to Windows 8 in compatible mode to see what’s going on.
Since such issue can be caused by driver bug, please also contact the manufacturer to see if they can provide more information about this issue.

Skype works with WiFi but not with 3G

I have a Sony Xperia M, Andriod 4.3 and the last version of Skype. Skype runs perfectly with WiFI but when I turn it off it gets offline with my 3G. While other apps like Facebook Messenger, Whatsapp, etc work well, Skype is logged in but offline: I can't send or recieve messages or calls and I see all my contacts but I can't see who's online. A friend has Sony Xperia M2 with Android 4.4 and is having the same problem with his 4G connection.
What can I do?
Note: Clearing data, as it has been suggested in other posts, doesn't work.

I have the same issue with a Samsung Galaxy S4.

Whats the diffrence between the ipad with wifi and ipad with wifi and cellular

Just got a new IPOD Touch and it wont connect to our Wifi home network with a Belken N Router. Our router uses WEP 64 bit security, but had a "blank" password field, which the IPOD did not like. Changing to a 6 char numeric PW didnt help either.

OS is whatever OS ships with current IPOD Touch
I cannot understand why the APPLE engineers have designed this product so that it has SO MANY WIFI problems. This is supposed to be an easy-to-use product. We've had no problems connecting our new laptop, our ROKU box, etc, but it seems impossible to get the IPOD touch to work. NOTHING LIKE SPENDING XMAS MORNING DOING APPLE TECH SUPPORT TROUBLESHOOTING TO LEAVE YOU IN THE CHRISTMAS SPIRIT!!! Argh!
In fact, the only way we have been able to get this expensive brand new IPOD to work on our home network is to DISABLE SECURITY in the router settings. THIS IS ANYTHING BUT A GOOD IDEA.
DON"T KNOW WHY BUT MANY OTHER USERS ARE REPORTING THE SAME KIND OF PROBLEM SO APPLE ENGINEERING NEEDS TO GET BUSY AND FIX THIS PROBLEM SO THAT NEW USERS CAN CONNECT TO THE INTERNET WITHOUT HAVING TO BE TRAINED ROUTER ENGINEERS TO DO IT!!!!
Ok, sorry for the rant, but surely those of you who are experiencing this share my frustration. This is not why I bought an APPLE product.
IS THERE ANY POSSIBILITY THAT APPLE WILL NOT ALLOW A WIFI PASSWORD with more than one identical alphanumeric character? Any ideas? We also tried eliminating the 40 MHZ setting under Bandwidth settings in the router settings for our router, but it made no difference. The router has the latest firmware, too. Running out of ideas, and am ready to box this unit up and send it back!

Thanks, Bob! You are correct. And, we learned this as we spoke with APPLE TECH SUPPORT by phone on Christmas day (800-APL-CARE). One of their reps spent the time to help us troubleshoot this, but the boiled down conclusion is your answer, and to repeat for the benefit of others, here is what worked:
1. With our Belkin router set to "out-of-the-box" WEP 64 bit security, we could not get wireless access of any kind. Only with the Security Mode set to DISABLED, could we gain access.
2. Changing the router's security mode setting to "WPA/WPA-2...." and entering a new min. 8 char passphrase, and then entering that same passphrase into the IPOD Touch, and restarting the router, did the trick!
Based on this, and some info found in another posting, I can only conclude that the IPODs and IPHONES do not support WEP security mode in many generic routers used by thousands of consumers. Hopefully, those same consumers can figure out how to change their wireless router setttings to WPA/WPA-2 security mode and ALSO get all their other wireless devices (PCs, laptops, WII boxes, ROKU boxes) all reconfigured to WPA mode, too.
I THINK THE BOTTOM LINE HERE IS THAT THERE IS AN ISSUE THAT APPLE NEEDS TO ADDRESS WITH WEP COMPATIBILITY and it may also be the case that MOST CONSUMERS ARE USING WEP 64 BIT security on their home wireless routers?
In any case, it's working now, so anyone who is having problems should try changing to WPA mode and post back here if it worked for them!

4s trouble with wifi. it connects however is very slow then switches back to 3g

If anyone out there could help I would appreciate it!
iphone 4s brought as a replacement form Apple on the 6 September 2013 has developed an issue!
I can connect to my home BT HomeSpot however its so slow and will then go back to 3g, so frustrating! I have a BT Booster and the single is strong, we have no problem with any of our other devices.
i've been to the Apple store twice now and they've said there is nothing wrong with the device as it works on there wifi!
Can anyone help?

I have brought the Virgin Media super hub back to the manufacturing original configuration then changed the user name and password. Only my iphone was connected. Then I've switched to 5 Ghz = 30Mbpm BANG!; went back to 2.4Ghz=dead. Now is getting worst. At the beginning it was picking at least 2Mbpm. Then 1. Then 0.something. Now it doesn't even connect. I'm pretty sure the iphone 5 must have 2 antennas and the one that uses 2.4Ghz is just gone.
Any advice?

Imac cannot connect to with wifi, cannot connect with ethernet
