Swtichs lost connection in trunk interface but still turn on

Dear Friends,
Since a week ago i have problems withs 4 or 5 access switchs that randomly lost the connection in trunk interface. The led in trunk interface turns off and i have to go to the site and turn off manually the switchs an then turn on to stablish again the connection. Before to turn off the switchs the logs shows:

This is common in all the switches that lost connection. The MACs are different in all switches so i cannot know if there are an specific host that causes the problem. Please your support.

Hi Reza,
Both ports are trunk.
interface GigabitEthernet1/0/4
switchport trunk encapsulation dot1q
switchport mode trunk
interface GigabitEthernet1/0/11
switchport trunk encapsulation dot1q
switchport mode trunk
Any idea?

I have an 8GB ipod touch and suddenly I'm able to access only the "sent" mailbox of Mail and not the other mailboxes. I turned on and off. I connected it to MacBook but still I can't access the other mailboxes.

- Try resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.

I lost my $20 itunes card but still have receipt of purchase Can i still redeem it?

You can ask, but there's almost certainly nothing they will be able to do for you. Gift cards, from any retailer, are almost always treated like cash and hence cannot be replaced if you lose them. Apple's terms say:
Neither Issuer nor Apple is responsible for lost or stolen Gift Certificates, iTunes Cards, Content Codes, or Allowances.
Sorry, but you're probably out of luck.

Lost mouse connection. Replaced batteries but still no recognition. Advice?

I had a message saying 'Lost connection' with mouse icon.
I replaced batteries but still no recognition.
Advice?

First make sure the batteries aren't dead and that the keyboard hasn't already been paired with another device that's in range. If it hasn't, the keyboard should pair automatically when you reboot. You may have to press and hold the power button on the right side of an Apple keyboard until the LED starts flashing.
Otherwise see these support articles:
Mac mini (Mid 2011 and later) and iMac (Late 2012): Bluetooth keyboard may not pair during Setup Assistant
Apple Wireless Keyboard: Difficulty during pairing process
If you have a third-party Bluetooth keyboard, you may need a wired keyboard to complete the pairing process. It's a good idea to keep a cheap wired keyboard and mouse or trackball as backups for a desktop Mac anyway, because Bluetooth isn't completely reliable.

Nokia Connectivity Cable Driver repaired but still...

Hey there, I had moved messages stored in the phone to PC via Nokia Suite before, however I got a nokia connectivity problem so nokia suite cannot detect my phone/search it via bluetooth now. I tried to fix it by using the method of repairing ‘Nokia Connectivity Cable Driver’ but it doesn't work. Everything went smoothly but still nokia suite cannot detect anything. So I may need to reinstall the whole nokia suite but the main concern is that if I reinstall my nokia suite, the SMSs stored in the Nokia suite will lose is it? So may i know what I can do?
Phone: Nokia 5800 XpressMusic
Version of Nokia Suite: 3.8.48 (should be the latest)
Computer: Windows 7
Thanks.

Thanks however, the problem is that Nokia Suite cannot detect my phone so how can it copy the text to the clipborad?

I'm connected to the network, but still can't get online!

I use airport to connect to the internet in my home. I have a very strong signal and my computer says I'm connected to the network, but I still can't connect to the internet. It just stopped working. Running diagnostics doesn't help- it just tells me to restart the device, which I've done over and over to no avail.
iMac Mac OS X (10.4.10)

Am a newbie but somethings may work here, Go to dock preferences and to network and to your airport connection window.
You have a green light signal in network status window? If it is yellow or red it is unavailable. If your connection is full of traffic, this may effect connection.
In window you may need to type in optional search domains. Your provider should tell you this no one else~ They would also walk you through your connection failures. If it is yellow and you connect to your provider's router and don't have your own router, this number may not appear in your connection information. You need to tell them their router is down so they can fix it. They may not find out if pings come back. Pings may also be cached (I am not sure but it might) so it may take them a while to find out if you don't tell them. I would call your provider. Maybe empty your preferences in your browser. You may have cookies or garbage to empty there. Use another browser.

Most public places require that you agree to their terms and conditions prior to allowing you full access. Next time you connect, tap Settings > WiFi > and then tap the blue ">" next to the network with a check mark. Tap Forget this Network.
Then tap Settings > WiFi and let the touch find the network. Tap on the name to connect and then wait for 20-30 seconds. If the network requires you to agree to Terms and Conditions, a Safari-like page will open up that allows you to do that.

Help, Connected To The Router, But Still Not Connecting To Internet

We bought a router and a wireless adapter a few years ago, I moved out and then moved back. I tried to connect to the network we setup in the first place, but it didn't work and I was told that I had to reset the router, so I did, and I setup a new network, and the computer with the router is working fine, but the computer with the adapter, even after I ran the setup disk on it again, all it does is connect to the router, but I'm still not getting the internet. If anyone has any ideas on how I can remedy this problem I would really appreciate it if you would share it with me. Thank you.
Adapter Model # - WUSB54GC
Router Model # - WRT54G2

Try and download the driver for the adapter again. It can be found here.
Also for the router, that can be found here.

Airport Extreme is connecting to the internet, but still flashes orange.

I've set up an Airport Extreme and it is connecting to the internet, however its light still flashes orange on the unit and in Airport Utility ver. 6.2 and it has a red circle with a "1" in it similar to the alert notification on an iPhone for messages and email. What does this mean? As I said, I can connect devices to it and connect to the internet, so it seems to be functioninbg fine. So why isn't the status light green?

If the problem does not resolve itself by powering down your network equipment, a complete reset of all your equipment is justified. Power down the modem and "hard reset" the Extreme, followed by reconfiguring it using AirPort Utility.
Power down your modem whenever you change what is physically connected to it. Make it a habit.

Originally it had the "double nat" issue but when I went to bridge mode my whole set-up failed.
That should probably be resolved as well. More information is required regarding this failure.
Sometimes, an attempt to reconfigure a minor setting will result in what appears to be a total meltdown followed by extreme user frustration. In that event, starting over with a "hard reset" and subsequent reconfiguration is generally the best way to proceed.

I'm actually the 15-year-old son of the person this account is signed up for (he's making me fix it because he has other things to do), but anyway, I'm experiencing the same problem, but I will go into a bit more detail than Estilo to verify it is the same and hopefully get a bit more help:
My dad's computer can connect straight to the modem (MSN Arescom NetDSL 800) and run the internet just fine, but only his computer; I've tried plugging my Xbox 360 directly into the modem, and it cannot connect because the ISP knows that it's not my dad's computer...?
But the internet will not run through the router to any computers connected to it. My dad's computer is even wired to the router, and still no internet. We've found that it's an IP issue, and trying to change that doesn't work as it give us a "169" IP (a "router is there, but I can't communicate with it" IP address) whenever we try to fix anything, rather than the "192.168.1.1" or ".2" that we should have.
My dad thinks (and I'm not entirely sure he's correctly, but I mostly agree with him) that the computer is the actual central hub for the internet, as in that it runs the administrative settings and makes the internet actually work for the rest of the computers (if his computer isn't on, no other computer can connect to the internet); the router is basically just a splitter.
The thing is, though, that this problem started randomly about 2 weeks ago as my dad was just looking up some things on craigslist.com; that was the point when the IP addresses changed completely for an undiscernable reason. And 2 weeks ago, my computer was able to connect to the router wirelessly and access the administrative settings. My cousin (who works in this stuff) recommended that I see what I can do to fix the problem by editing the administrative settings from my computer, but now I cannot connect to the router whatsoever.
My dad and I have narrowed it down to a driver problem, and I'm not sure what to do about it. The reason for this is we tried getting a new router (the WRT54G), and the same connection issue remained. If this is the problem, you know what the problem really is, or you have questions, let both me and Estilo know.
Simplified Outline:
+ comp to modem (MSN Arescom NetDSL 800) [working]
+ comp to router (BEFW11S4) [failed]
+ comp to new router (WRT54G) [failed]
+ router to internet [failed] (incorrect IP to connect to ISP)
+ not a router problem
? driver problem
? designated computer needed as central hub
- wireless connection to router was recognized (no longer works?)

IPad Mini connected to home network but still not connecting to internet.

Hi. I have a friend staying and she has an iPad mini. while all other Mac devises are connected to our home internet, her one will not. I have set the network details on her mini using the static ip option and get the blue tick beside our network name. However, we are still not connected to the wifi network. All our Mac devises are connected and her husband's iPad and iPhone are working fine. Help

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 drooping 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

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
