X220: Connected to a 4G network with 21Mbit/sec - A pleasant surprise!

Yesterday i was at a meeting, where i normally is connected to 3G WAN with 7.2Mbit/sec. - i started the connection as i normally do, but discovered that i connected to a 4G network with 21Mbit/sec. I didn't even know that the WAN card in my X220 was able to do that. So i tested the connection immediately and i could download with 1.5Mbyte/sec. effectively.
It was a pleasant surprise!

Solved!
Go to Solution.

It seems your modem works at full speed for the 3G networks - HSDPA mode, 14.4 Mbps (Cat 10) downlink speed. Try upload and measure the speed. May be you'll get in the HSUPA mode up to 5.76 Mbps (Cat 6) uplink speed.
At the same time you see 21 Mbit/sec in the connection status window... Very interesting.

Try:
- Powering off and then back on your router.
- Anything else here
iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
- Change the DNS to either Google's or Open DNS servers

Can't connect to a wifi network with a wep keyid 2

Hi,
how do you connect to a wifi network with wep but the keyid is 2, i can't find an option.
i put the password, in asci and in hexa, and the answer "can't connect to the network" a xp near got connected after changing the key id in configs :((
did i miss something?
thanks for help

I am relatively new to Mac's, as at 40 having had IBM/Windows compatibles since I was 14 (8086 woot!), I am still learning.
However, I believe the answer is that you must use Key 1. I don't believe OSX offers the chance to use any others. However, in case I am wrong, try putting a $ before the WEP passphrase, but again, I think it only uses Key 1.
Hope that helps,

Unable to connect to home wireless network with my iPod touch

I've had my iTouch for several months now and I'm still not able to connect to my wireless network at home. I've tried the resets and other suggestions I've found in the discussion groups but nothing has worked.
I have an older Netgear Router MR814v2 and it is unsecured. It is attached to my old desktop, HP Pavilion running Windows ME, which is not able to run the itunes software. My HP laptop is where my iTouch and iTunes software is installed.
The iTouch displays my network with good signal strength, but when I try to connect I get the "unable to join the network "NETGEAR".
Going to my router, it does not recognize my iTouch as an attached device. Why is that and what am I missing?
Thank you for all suggestions and your help.

I tried powering down the router. When it's off the iTouch does not recognize the network and then when it's powered on again, the iTouch recognizes the network. Unlike the public wi-fi spots that my iTouch responds to, where all the info like IP Address, Subnet Mask, Router, DNS etc are populated in the settings...my iTouch does not populate these fields at home even though it recognizes the network. I still get the unable to connect to network error. Could it be that my router is antiquated and can not support the iTouch? Like I said earlier, my Router does not recognize the iTouch as being attached to it.

Why can I connect to my home network with my iPhone 5 in one room, but when I move to another it is 'unable to connect to the network'

At home, I can connect my iPhone 5 to my home wifi network with no problems, as long as I stay downstairs.
As soon as I go upstairs my phone disconnects from the network. I can still see the home network it in the available network lists (with full signal strength), but when I try to reconnect I get an 'unable to connect to the network message'
If I move back downstairs it reconnects
This has only started happening in the past week or so
I've tried to forget and rejoin the network, but this doesn't work
I reset my network settings on the phone. This worked for a couple of hours and I could connect to the wifi upstairs, but now it won't connect again.
Does anyone have any ideas what is causing this?

Sounds like your wi-fi signal strength has degraded. Try rebooting your wi-fi router, or get it serviced.
Do you have similar issues with any other wi-fi routers?

Connection to wi-fi network with apple devices is highly unstable

About a year ago I bought a 1TB time capsule that I use to create a wi-fi network at home. At wi-fi network I connected with no problem my Imac and Iphone 3g up to 20 days ago. Since then the connection to network has become unstable, I can not always connected with both utilities, especially with the iPhone that any attempt to link it to network indicates "can not access the network". Without change anything, sometime We can connect to network without any problem for some hours, sometime for some minuts/seconds. I tried several times to reset the configuration of the time capsule, also with qualified personnel apple but I have not solved anything. Today the connection to wi-fi network at home with apple devices is highly unstable.

Hi,
Thanks for your reply but as mentioned in my post, I've checked if drivers needed updating and it says the latest driver is already installed and updated for this device (network adapter). I double checked through the HP Drivers & Download page and scan for updates for out of date and missing drivers and software and it seems to scan to about 17% then I'm taken to another page with a link that goes back to software & driver downloads page so I click 'next' to confirm my operating system which then shows a long list of things to download and being that I know very little about computers, I don't know what I'm meant to be downloading or not? Everything? There's a total of 31 possible downloads listed (under their respective headings).
Have just rung the store that sold us this notebook a week ago and they are going to replace it as they've said it sounds like a faulty network card. Whew. I'm still a little confused though as to which of the downloads from HP's list I'm meant to download (assuming I'll see a similar list when we get the replacement computer) so if anyone can help me out with that, I'd really appreciate it. Thanks.

How can i connect to a wifi network with no internet connection?

I used to be able to connect my Z10 to a wifi network even when the network had no Internet connectivity when i got my phone in Feb. 2013 (10.0) However ever since the 10.1 update this has stopped working. I cannot connect to my wifi network when there is no Internet connection. I cannot play videos / music from my phone to my tv/music system or connect to my laptop. However my laptop and tv communicate just fine through the same network.
Can anyone recommend anything for this?

Your saved wifi networks should connect automatically whether internet is available or not, you may receive a notification "there appears to be no internet connection".
Update to 10.2, if not available from your carrier then use Sachesi (see other threads).

I'm unable to browse the internet at home on my Macbook Pro (10.6.3), even though it shows I am connected to the wireless network with full bars.

This problem began weeks ago, when I suddenly couldn't browse the Internet at home despite being fully connected to the network. The network was a private, password-protected wireless network set up through a Netgear router.
I have spent hours troubleshooting and have tried multiple fixes including resetting PRAM, deleting and re-creating Airport, deleting and re-creating networks, changing IP and DNS, etc. to no avail. My roommate's PC works perfectly fine on the same wireless network.
This seems to be an issue with networks I use long-term. I can connect fine to networks at Starbucks, etc. for short-term use. Also, while trying to troubleshoot my connection issues on my home network over the last few weeks, I'd been using my apartment complex's public wireless connection (no password) with no issues. All of a sudden, I am having the same exact issue with that network. It's like something just snaps and maybe gets configured wrong after a few weeks or months of use.
I am desperate to find a fix, since now I can't use the internet AT ALL while at home and need it for work.
Thank you in advance for your help!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode.)

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 the 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 make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Could it be this:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem. A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

Problem staying connected to my Wireless Network with my HPPhotosmart e-All-in-One Printer - D110a

I just bought a new HP wireless printer replacing my old HP wireless printer which the wireless part worked fine, but the printing died.
New printer HPPhotosmart e-All-in-One Printer - D110a. I have installed and re-installed the software and drivers but can't get my printer to stay connected to my laptop. I have a Linksys "WRT54GL router but have the printer set with a static IP address. When I run tests on the computer and printer everything says it is fine. But every 30 seconds or so.. my printer goes offline on my computer and is especially noticeable when I am using the HP Solution center because it will keep blinking in the windows bar. I have talked to 4 technicians but no one can figure out what the problem is. They keep saying that it is on my end, but the old printer which was also an HP (Wireless 6150) never had any problems and I have not changed anything in my routing. Is anyone else having this kind of problem and has found a successful solution? Any help would be greatly appreciated.
My computer is running Windows XP SP3
Currently my router has WEP encryption, but I tried them all just to see if that had anything to do with it. (WEP works best for me since I have some devices which can only use WEP to communicate).
Thanks.

Let's set a static IP address for the printer:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). Yours is 192.18.1.100 to .149. Let's use 192.168.1.200 for your printer.
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router's IP (on the Network Config Page) for the gateway and first DNS. Leave the second one blank.
- Click 'Apply'.
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you may need to redo 'Add a Printer' using the new IP address.

Connecting iMac to Windows network with domain

i tried to connect my new iMac to the windows network at the office. it would not find the server. any suggestions

Hi,
To connect, I need to 'configure encryption as AES', which I'm not sure how to do on OS X. Furthermore, after signing in with my college ID I am required to 'Use the domain name [domain name]' and 'configure your browser to use the college proxy servers [example.example.net] on port [123]
The encryption should be configured automatically. To use the proxy:
1. Open System Preferences
2. Click on Network
3. Select Airport from the list on the left
4. Click on Advanced, near the bottom right
5. One of the tabs will be called Proxy. Configure your settings there.

Cannot connect to ad hoc network with iOS 8

I am trying to use my iPad air on iOS 8 to connect to an ad hoc network I've set up on my PC (windows 7).
The network appears under devices, and when I try to connect it says "(Name) is not connected to the internet. Are you sure you want to use this network?" and gives the option to join anyways. I tried joining, but the internet does not work.
When I set it up previously and had my iPad on iOS 7, I did not have this problem. I am not sure how to fix it.
Unfortunately I do not have any other devices to test my network to be 100% certain that the issue lies with my iPad, but this is my belief since I didn't have this problem before upgrading my OS.

Same here!
Windows xp
I've been using adhoc with my iPhone 5 on iOS 7 with no issue, now with iOS 8 it drops the connection right after establishing.
The same behavior used to happen when I tried to watch any video on the iPhone iOS 7 through adhoc, it dropped the connection just like it does now on iOS 8.
