E540 Can't detect wifi visible by other devices

Hello community,
I would like to ask for help. I am facing a very strange problem. I have windows 7 Professional 64bit (SP1) installed Lenovo Edge e540 notebook with Intel(R) Wireless-N 7260 wiffi adapter. I am not able to even detect my home wifi network, that is detected with my other devices (another laptop, smartphone) without problems.
I have to mention, that at work, I can detect all surrounding networks (b, g and n).
I've installed Ubuntu operating system as my second OS and my home wifi is detected and I am able to connect without problems.
I tried all "standard" solutions - check wireless network switch, update dirvers from Intel, update drivers from Lenovo, complete driver uninstall and reinstall, nothing helped. My home network was never detected on windows.
I also tried to change all additional settings in wifi driver section, with no success too. Could I ask experts here, what could be wrong?
Any suggestions where to look, what to try to change would be appreciated.
Thanks.

Hi Jiri,
which channel is your home router transmitting on and have you tried changing this? Is the router set to broadcast the SSID?
You might also like to post which router you have and the type & model number of your E540, please do not post your serial number.

Brand new MBP rarely detects Wifi network- 4 other devices have no problem

I am using a 4-week old MBP with Lion that was installed via the App Store immediately after purchase.
I read up on the Wifi issues with the MacBook Pro / Lion but mine seems a bit different.
Once I get connected to Wifi, the connection doesn't drop and is not weak, however, getting the connection is the problem. Airport detects my network off the bat only about 50 percent of the time. I live in a city with about 20 networks available at any given time. When I click on the airport icon, the same 4 networks (not mine) appear immediately every time. After waiting or re-clicking, if I'm lucky mine will show up in the list after about 20 to 30 seconds, but sometimes it doesn't show up at all. Restarting the router doesn't seem to help. Sometimes rebooting the computer does, and once in a while after a reboot my MBP will find the network immediately and auto-connect... when it does that the pages load at lightning speed and it works great until the next disconnect (when it sleeps).
Could this be my router just being too old for my MacBook Pro? My iPhone, iBook, PowerBook G4 and Asus laptop have no problems.
I've tried changing the broadcast channel on the router, deleting the plists frequently mentioned in these forums, deleting and re-adding the wireless connection (many many times), moving WLAN up to the top of the list in Network Prefs, updating router firmware, routing through my iPhone (no problem)...
Please help! Should I take it back to the store for an exchange? I bought it in the US and live in Germany... not sure I can even do that.

System Preferences > Network > Airport/WiFi
Even if WiFI is at the top, use the gear below the list of Interfaces to choose "Set Service Order" and put Airport/WiFi at the TOP. This will make a big difference.
Click ( Advanced )
In the WiFi/Airport pane, be sure the Networks you most want to join are listed at the top of the list, and feel free to delete any you don't care to join automatically. Once you have a good list, check [√] Ask to join networks (rather than just joining them).
In the TCP/IP pane, set IPv4 to DHCP and set IPv6 to OFF or Manually OFF.

IMac suddenly can't detect airport express; all other devices can -help!

Literally overnight and with no changes in settings, etc. my iMac (running the latest version of Tiger) will not detect airport express. My laptop still detects it and connects just fine; my iphone connects via wifi, etc. It's just the iMac that isn't working.
Upon starting up my iMac this morning, I was prompted to "update airport firmware" which I did. Ever since then I can't get the computer to recognize airport.
I've worked on it for 2 hours disconnecting and resetting the modem; checking and unchecking boxes in the network settings, trying to renew the dhcp lease, etc. When I scan for wireless devices, the iMac does not detect one. If it does detect it, I get an "there was an error connecting" message.
So frustrating, especially since I have used this in the same way for over two years and have had NO problems until this morning.
The airport express has a solid green light. Any help is much appreciated!! Thank you.

Hi guys, its me again....
Dunno if is the same problem, but i dont think the problem is the airport, all of you (as i did too) tried making new users, deleting preferences, etc etc...
I tried resetting the airport, and is the same, is something in the computer that trigger the issue after the firmware in the airport, dunno how, but as far i saw, its the problem...
At least for me, after lost the connection, my airport on-off button stop working, if i turn off the airport in the upper menu or in the network preference panel, go off of course, but if i try to turn it on again, desnt work anymore, the button works of course, but never change to ON state...
that button issue isnt a hardware airport issue, is a OS issue...
:S
P.D.: i've trying to replicate some situations on the computer, programs, task etc, bcuz' by some reason there's something that trigger the desconnection... by example, right now i've more than 4 o 5 hours without the problem yet.... but.... i've using none or unusual programs to make the regular tasks...
And last night, i leave the computer connected to internet the whole night, no user interference and was online all the time...
something is the trigger..

You can't downgrade the iOS level.

Go to your ipod touch wireless settings chose your network and right beside there is button looks like ">" click on that check the dhcp what IP are you getting? do you get any ip? if you do your ipod touch should work with wireless no problem. Also, you may have to enter wep key again. After that it shou,d save your device

There is a huge difference between sending email and sending messages.
Yes, I believe you when you say you can only send messages to other Apple products. The iPad is not a telephone, and therefore, it cannot text message. It can only iMessage, which means it can send and receive messages to/from other Apple products if they are on WiFi or an iMessage capable cellular network.
Email, however, is a whole different category. I don't really think you can only exchange email with other Apple products only. Make sure you have correctly identified the symptoms.

I downloaded a movie on one of my computers, and yet I can't see it in my purchases and I can't download it on any other devices. Any suggestions?

Films will only show in your library if you've downloaded it on that computer or copied it from another computer. You checked the Purchased link under Quicklinks on the right-hand side of the store homepage to see if it shows there for redownloading on that computer
If it doesn't show there then you can copy it over from the computer that you downloaded it on e.g. via home sharing : http://support.apple.com/kb/HT4527 (that page refers specifally to music, but it works for other content types as well).
Or you can right-clidck (control-click on a Mac) on the film in the iTunes library that it is on and select 'show in explorer' ('show in finder') and copy it to, for example, a flashdrive, and use that to copy it onto the other computer's iTunes library (File > Add To Library)

Can I delete old backups from other devices if my new iphone 6 has a current backup with everything on my new phone?

Can I delete old backups from other devices if my new iphone 6 has a current backup with everything on my new phone?

Hi there dyarrell,
You can do this if you are confident that your current device has all of the data on it that you want to keep. The method for deleting the backup will be differnt depending on the backup method. Take a look at the articles below for more information.

My new macbook pro can't detect wifi sometimes...

hi guys...
i just bought late 2011 macbook pro on 27 april this year...it was succesfully connect to any wifi at anytime & anywhere...
but the problem begins when i stayed at my brothers's house...
my macbook can connect to the wifi there for the 1st time, but after i shut down my MBP and turn it ON again, it cannot detect the wifi at my brother's house, but it's weird when it can detect wifis from neighbourhood...
there' a solution for this problem...i have to repeatedly turn ON & OFF the wifi on MBP many times before it successfully connected...
but unfortunately after shutdown & turn it ON again, i've lost the connection again...what i have to do is repeatedly turn ON/OFF the wifi on MBP AGAIN until it was successfully connected...
pls help me, i already googled this problem but can't find the right solution anywhere...pls help me....thanks in advance....
*additional note:-
- my iphone4 & my ipad2 doesn't have the problem detecting & connecting to the wifi at my brother's house....
- i live in malaysia, my iphone4 & ipad2 is malaysian version but my macbook pro was US version...

Just finished trying the suggestion from my Mac store "genius", and it WORKED. He suggested that I connect to the router directly with ethernet. His thought being that once my MBP found the IP address it would be able to find the network wirelessly. While still connected I went to System Preferences/Network, selected WI-Fi and entered the network info (name & password). There it was - connected.
Don't know how to make this solution available to everyone with the same problem. If someone knows how, go for it.
Thanks to everyone who responded. Your efforts are appreciated.

My macbook wont recognise the wifi , but my other devices do?

struggling to connect to the wifi, my laptop just doesnt recognise the router, yet it recognises my next door neighbours networks, what can i do, all my other devices such as my iphone recognise it perfectly

Power off the router. Power it back on.
Wait until all the lights are properly lit.
Restart the Mac.
Best.

VPN connection works, but can't ping or access any other device on remote network

I have an OS X Lion server at work (uses a static IP of 192.168.2.10). VPN is setup and works.
The work network's router has an IP of 192.168.2.1 and hands out IPs of 192.168.2.100-149. The VPN service is configured to hand out IPs of 192.168.2.150-170.
My home network uses a router with an IP of 192.168.1.1 and hands out IPs from 192.168.1.2-49
Both routers are using subnet mask of 255.255.255.0
The problem is, I can connect to the VPN just fine and access all services running on that same OS X server like iChat and AFP file sharing. But, I cannot directly access any other device on the office network like client machines or even trying to log into the router's GUI interface. Pings timeout, etc.
Example:
At my home, I have a local IP of 192.168.1.12 and I connect to the work VPN. It assigns me an IP address of 192.168.2.151 and I'm able to connect to iChat on the OS X server that has a static IP of 192.168.2.10
In terminal, I try to ping the router on the work network (192.168.2.1) and I get no response (even though ICMP response is turn ON). I try to ping another OS X workstation on the work office, and get no response.
I'm not sure how to fix this, or whether I need to change settings on either router or the server.
Would greatly appreciate any insight or help on this. Thanks.

Check the DNS settings on the server (see my earlier post in this thread).

My iPad is not connecting to wifi when any other device is. what do I do?

My iPad shows that it is connected to the wifi at my house, but when I try to load anything, it doesn' t work.
On Safari, it says "Safari cannot open the page because it could not establish a secure connection to the server." And Google Chrome gives me a similar message.
What do I do? I tried resetting the ipad and turning the router off and on again.

Try the following steps.
Go to settings> general> reset>reset network settings.
once the reset is complete, try joining the WiFi network again.. you may need to type in the WiFi key again

My Ipad doesn't connect to wifi while all other devices are connected.

My iPad doesn't connect to wifi anymore while all other devices in the same network are connected including iPod.
iPad was connected this morning, but quit connecting since this afternoon.
It tries to connect, but everytime connects, it disconnect within a second, and it keep doing the same thing.
This is the first time ever I see this problem since I started using this iPad.
What happened to my iPad??

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
