WRT 160 Laptop Connection Issues

I travel frequently with my older Compaq laptop that runs Window XP Professional. I connect to several different wireless networks while I travel. Occassionally when I return home from a trip I get a message that says verifying identity and the laptop will not connect to the wireless network. I have had this issue in the past and I believe one of the solution was to remove the network from the connect automatically setting and do it manually. I tried that to no avail this past time. The laptop appears to have finally connected (after over a week of attempts) and the internet is functional, however I still have the validating identity icon on the taskbar. Any ideas?

Click on the Start button >>> Control Panel >>> Network Connections- Here right click on the "Wireless Network Connection" icon and select Properties- Click on the 'Authentication' tab- Uncheck "Enable network access control using IEEE 802.1x" and click on Ok.

Pre Plus Mobile Hotspot laptop connection issues

Hello All.
I think this is a duplicate post because I hit enter accidentally! Sorry.
I am having a problem connecting my laptop to the internet using Mobile Hotspot through VzW. I have activated the feature on VzW, have the software loaded on my Pre Plus and have tested it successfully with my daughter's iTouch device. She was able to easily connect and access the web while we were in the car.
My laptop recognizes the MHS as a WiFi access and connects to it initially. When it tries to acquire a network address, it fails. I says that the connection has limited or no connectivity. I cannot get on the web with that.
My question is what settings I might need to set on my laptop to help with this connectivity. I have WAP Personal set with the appropriate Key on both devices.
Any thoughts from anyone? I would appreciate any help. I like the concept of the feature but not being able to connect my laptop really puts a damper on my enthusiasm!
Thanks for any help you can give.

I had the same issue. I resolved it by using a passcode that has 8 lowercase letters and no numbers...

Bluetooth to laptop connection issues

I have been trying to no avail to pair my Q10 with my laptop. Everything goes well until I want to pair the two. The computer sends a number to the phone and I accept because they match and then all the drivers are installed after this I try and connect to the computer through my Q10 and receive a message stating,"Con't Connect. In device setting on your BlackBerry device, turn on Internet Tethering using Bluetooth." I am not trying to set up this bluetooth connection for internet tethering and cannot turn that option on because I do not have a tethering plan. Any possible reasons and help would be appreciated, thank you. Photo at the bottom is what I receive when I try to connect. I'm running OS 10.2.1.2141 and it was also the same issue on OS 10.2.1.1925

You do not need tethering data to turn on Internet tethering you only need internet and when you do turn it in make sure you can see the CONNECT to BLUE TOOTH option and make sure that that option is on.
It would also help if you had BlackBerry Link

Ipod/laptop connection issue.

Basically my computer wont detect my ipod at all.
The Ipod isnt new i got it last christmas, its an ipod touch 16gb. It worked up until i rebooted my computer and reinstalled itunes. My ipod still has everything on it but it wont detect with my computer or itunes, i have also logged into my account on itunes successfully.
Ive tried:
1.Turning computer off and then on.
2.Reinstalling itunes.
3.Turning ipod off and then back on.
4.Re-booting ipod by holding the lock and menu buttons together.
5.Tried more than 1 USB port.
6.unistalling + reinstalling USB controllers and USB drivers
I may have missed something ive tried, but if someone mentions it, ill say.
The cable included with my ipod could be broken due to a split in it but it still works when it is plugged into the mains using a mains adapter it still works, also my brothers cable works on my ipod too to charge it but not to connect it.
Thx in advance, this has been a problem for a while now and im tired of it after trying almost everything =/

I have already tried this, as it continued from the AMDS guide. No luck
EDIT: just plugged in again when the ipod was unlocked and it worked this time but now i have the problem that the computer gives me the option to install it as a camera/scanner or to install it with photoshop =/ how can i get it to install with itunes because my computer thinks its a camera O_o?
EDIT 2: I changed the scanner and camera options so that it wouldn't be detected as a camera and now its not detected at all again =/

I have Snow Leopard 10.6.8 on my MacBook. Constantly dropping internet connection or message "error connecting to the network" comes up. No wireless connectivity issues with windows 7 laptop or iphone.

I have a MacBook with Snow Leopard 10.6.8. The last few weeks it has been constantly dropping internet connection, and one of these messages appear on the page: "Safari cannot open this page because the server where this page is located isn't responding" or "Safari cannot open this page because you are not connected to the internet" comes up. I will check Wifi and I am connected. No wifi connectivity issues with iphone or windows 7 laptop, this doesn't happen with either of those devices. I have unplugged and reset router, cleared cache, still happening. Any ideas? Thanks in advance.

Connectivity Issue (Macs work, Windows laptop doesn't)

We recently switched out a Linksys wireless router and replaced it with a Time Capsule. There are two Macs (iMac & G5) which connect to it without any problem.
The problem is with a Dell laptop running Windows XP. We need to run a VPN client to connect to a work server. The Dell laptop connects to the Time Capsule without a problem, but after a few minutes, the connection is lost to the work server.
Here is the error message:
*Connectivity VPN Client*
*Unable to resolve the IP Address of the remote server. Verify the host name in the Destination field is correct.*
This was never a problem with the Linksys router. Is there a port that needs to be configured on the Time Capsule?

I'm trying to forward the windows from xemacs and gnuplot.
What happens when you try to run them? Do you get any kind of error message? Have you tried just xterm?
Is it possible you have DISPLAY set to something on the Mac side?
Currently I am using putty to connect to the mac via ssh (and have the enable X windows forwarding box checked), and I have Xming running on my laptop to display the x windows. This setup works fine for connecting to unix machines, but it doesn't work for connecting to the mac.
Does the Mac have the firewall turned on?

Lan connectivity Issue on autonomous AP with throttles

          Hello,
I encounter a strange problem on several AP 1242 in version 12.4(25d)JA1 of a customer :
He has 10 autonomous AP covering a factory and is using them for laptop connectivity and TOIP with mainly 7921 Cisco Wifi Phones.
The phones are configured to use only 802.11a.
The APs loose LAN connectivity randomly and therefore the clients don't work anymore.
The AP are connected on a 2960 and a 3560 wich are in turn connected on a 3750 wich route the trafic.
After checking spanning-tree no loops are present.
When I check the counters on the AP involved I see the "trhottles" and "ignored" counters incrementing on the fa0 link of the AP impacted wich mean I think it can't handle the incoming traffic. This incoming traffic seems not to be too big however. I can see drops on the switch interface connecting the AP.
There is a lot of roaming on the AP due to people walking in the factory with their wifi phones.
Here is a view of the fa0 counters :

Does someone ever experienced a similar problem ?
When I shut radio interfaces they're is no more problems on the LAN. Can this be an overlapping coverage issue ?
Can someone please give me advices on how to troubleshoot this issue ?
Thank you in advance as I'm a bit stuck.
Best Regards,

     Hi Scott,
Thanks for your reply.
Do you think this can be the origin of the issue my customer encounters or is it only to be standard ? As this change will have to be made on all clients, if there is a chance it solves the problem I will do it ASAP, if not I will delay it in a less busy period :-)
Can the constant roaming associations and dissasociations overload the AP and make it stop responding on the LAN or is it only a throuhput problem ?
Thanks in advance for your answer.
Best Regards,

My brand new mac pro always had Internet connection issues at school. WHY is that? I see the school's Internet working perfectly fine on other PC's, but there is never a day where my mac doesn't have Internet connection issues at school. How do I fix it?

I got my mac pro in the middle of August. School started the week after. Internet was working perfectly fine at home. But at school, I never had a good connection. Sometimes on the good days I get a connection when I'm sitting at the exact spot in class I always sit at. It's ridiculous and it's frustrating. I invested my money into this laptop and I'm beginning to regret it. I thought it was the school's Internet, but I don't see Internet issues with other PC users. It's most frustrating on registration days and I'm trying to register for my classes before it gets taken, but again... Internet connection issues. It's random. Majority of the time, it doesn't work at all. I've done Network Diagnosis and turning WiFi off then turning it on again. I've done everything I could. I put my money on this laptop and it was a lot of money. I could have bought an 800 dollars laptop and I would have Internet connection anywhere on campus. So, I don't want to continue everyday to regret on buying this laptop every time I try to connect to the Internet at school or Starbucks or anywhere else. How do I fix this? What's the problem ?
At school, I heard this guy had a problem with Internet connections too and he owned a new mac book pro. He said something like Apple messed up on something, but he fixed it. If I knew mac book pro's had these issues I wouldn't have bought it in the first place. It's freezing on me every other day. It's ridiculous. But what concerns me the most is the Internet connection. So someone please tell me what can I do next to prevent the problem? Am I doing something wrong maybe?

Hi Kevin,
I'm using an XLR input mic which is connected to the phantom power enabled XLR mic socket on a USB M-Audio M-Track. The M-Track is connected by USB to the Mac Pro - so effectively I've got an M-Audio USB soundcard with a mic input. I've also tried a microphone that is a straight XLR to USB cable (guessing with some soundcard chip buried in the usb plug) but that also yields the same effect of bad latency, intermittent quality, stuttering and repeating and echoing (without the speakers on during record so its not feedback).
The mic works absolutely fine with other recording applications I have on the mac at the moment - albeit non-adobe ones (tested it on the EasyAudioRecorder - and it lives up to its name. it's easy)
I will try with Audition and report back, but sitting here right now I can imagine it would work fine with audition too - it just seems to be the way premiere is set up for recording into the timeline is a bit sketchy. I'm willing to accept it might well be a quirk with the new Mac Pro trashcan - I'm not weighting all the woes on premiere.
Any thoughts or am I out of luck to sit with my fingers crossed for a fix in the next round of updates?
Nathan.

X1 Carbon (20AX series) wifi connectivity issues

Dear Lenovo Support and all others,
I am posting this in hope that someone can help with my problem and also to share my unpleasant experience with a new Lenovo product.
Lenovo Thinkpad X1 Carbon
Model: 20A8A00VSG
OS: Windows 7 Pro 64bit
Purchase date: 27th February 2014
Since the first day I purchased the system, I have been having an issue with my wireless connection:
1. I am unable to reliably get a wireless connection to wireless access points (e.g. free wifi coffee outlets or malls) and personal mobile hotspots (mobile phone hotspots). It constantly says "LIMITED CONNECTIVITY". In other words, I cannot get internet access. Even when it does connect to the network and get internet access, there is a tendency for the connection to drop back to "LIMITED CONNECTIVITY".
The only time I can get a reliable connection is when I am connected to my home wireless router. The system does not seem to have problems on home wifi networks. Since the problem seems limited to wireless access points and hotspots, I believe its a hardware/software problem.
Please note that I have other wireless devices (laptops and mobile phones) that can connect to the same networks that I am trying to connect to and have no issues.
I have tested the networks with my friends' wireless devices as well and they have no issues accessing the internet so I am fairly certain that there is no issue with the networks themselves.
2. I have already called in twice and been given advice on both occasions but the problem still persist. I have updated all drivers, uninstalled and reinstalled and updated the BIOS for the system and also performed a system recovery but nothing has worked so far.
I have also tried disabling and/or deleting any anti-virus software and firewalls but it does not fix the problem.
I have also been advised that I need to go down to the Lenovo service center to have my laptop checked out by the technicians and that there MIGHT be a firmware upgrade for the wireless card itself.
NOTE: MIGHT? The support staff doesn't even know for sure whether there is an upgrade available.
3. Rebooting my computer, the wireless card or the hotspots does not solve the problem. It might work for a shortwhile before it reverts back to it's non working state or stops working again once I reboot the system.
I am really unhappy with the purchase so far. It's actually a good laptop per se when all is working, but without internet access, it is pretty much like a dead fish. And thats 90% of the time.
Like I said, this problem has been happening since day one and I've tolerated it long enough.
I hope someone can help me with this problem.
Thanks all.
UPDATE - 3/24/2014
I borrowed an ASUS Wireless USB adapter from a friend and installed it on the laptop. Lo and behold there are no connectivity issues to my iPhone wireless hotspot.
INTEL DUAL BAND WIRELESS AC 7260 - NO CONNECTION/LIMITED ACCESS
ASUS USB N10 WIRELESS ADAPTOR - CONNECTIVITY AND INTERNET ACCESS
I think this narrows it down to the software/hardware in the computer....

Hi, all
there is an issue bugged driver or even card firmware related. Intel confirmed that. Wait some time for the new release.
For the test purpose only disable 2,4 ghz band support and switch to 5 ghz. N-band seems unstable so switch to G-band. As the Linux users report the same issue it's firmware bug basically.
x220 | i5-2520m | Intel ssd 320 series | Gobi 2000 3G GPS | WiFi

Macbook air Mini DisplayPort to VGA Adapter connectivity issues

Hi pple,
Would like to ask if anyone is facing connectivity issues with Mini DisplayPort to VGA?
I am currently using the 2nd Gen Macbook Air with Intel HD Graphics 3000 384 MB. Sometimes when I connect to a montior (Viewsonic VA1918wm) it works fine, sometimes it just does not work and the laptop just shows me a blue screen.
I tried with out with my friend's Mini DisplayPort to VGA adapter, it has the same problem. Does this means that my macbook air mini disoaly port got a problem?
Thanks
Bryan

I am experiencing the same kind of problem... only with projectors. Some projectors will display the screen and then others wont even register with the MacBook Air.
Using an Apple Min Displayport to VGA adapter. It's hit or miss if it works. Firmware has been updated on the adapter but this did not help.
Anyone help with this?
Thanks,
Nathan.

Possible Resolution to MiFi 2200 connection issues when using WiFi

I was having issues connecting to the Internet with my Windows 7 laptop using the MiFi 2200 as a WiFi device.
My WiFi adfapter was retaining the last IP Address it had obtained ... in my case my home network.
Go to a command prompt and do an ipconfig -release followed by ipconfig-renew.
It pulls an address from the MiFi from the DHCP range and works perfectly.
Hope this works for everyone!

Maybe also check specific for the 2 different tcpip protoclas loaded.. here is the solution that resolved my connection issue:
Updated Vista Home sp1 to sp2 ( 450+MB download )
Updated Atheros AR5007 drivers to 7.6 , 2008 release... there might be a newer release but I dont want to jack with it now that I'm working.
Check in network connections for wireless connection.
I had 2 TCPIP protocols loaded. v6 and v4 .. v4 had IP and DNS hard set. changed both over to auto assign
WALLA Mifi is now working wirelessly.

IPad2, Verizon 3G, VPN Connectivity Issues

Greetings all. I am the systems administrator for my corporation and have seen an issue that I wish to present to the community for discussion.
For those enterprise users that have an iPad2 with Verizons 3G, are you experiencing connectivity issues while trying to connect to your VPNs from the 3G network? If so, have you found any work around to allow connectivity or does it work fine for you?
Here's a summary of my issues:
We have a VPN server built on Debian Linux that has been in operation for over four years. It handles remote VPN connections from Windows, Linux, Android, OS X, iOS, and from many different devices including multiple flavors of Apple products (iMacs, Minis, MacBooks, iPads, etc.). To date, it has performed flawlessly with assorted devices connecting to it through broadband and assorted 3G networks.
Recently I purchased an iPad2 with Verizon 3G. I was able to set up the VPN connection using PPTP and connect using a Wi-Fi connection. When I turned off the Wi-Fi and attempted the same connection via Verizon 3G, it fails. I then took an associates iPad1 using AT&T 3G, set up the same connection, and was able to connect. I don't have access to an iPad2 on AT&T 3G so, I can't speak for that.
Here's the logs from the VPN server while connecting from my iPad2:

Quick connect, able to utilize VPN connection normally. No issues.

Jul 27 05:20:33 localhost pppd[31682]: Connection terminated.
Jul 27 05:20:33 localhost pppd[31682]: Exit.
As you can see, the peer refuses to authenticate causing the link to be terminated while attempting to connect using Verizons network. This is with the same VPN connection settings on the iPad2 that just worked with WiFi connection from the same device.
Here's what I can verify with regards to 3G networks:
Older (<4) iPhones and iPad1 using AT&T can connect
Windows and OS X based laptops using Sprint 3G can connect
Android based smart phones using Sprint 3G can connect
I have not called Verizon or Apple Support yet but, that's next when I have the time. My initial conclusion is that there is something with Verizons 3G services that is causing the issue. It may be that Verizon is using some sort of data compression process that is problematic with VPN transmission. While the log shows an unsupported IPv6 protocol when connecting via Wi-Fi, it still negotiates a successful connection and I don't think that's the root cause for the disconnect. Thoughts?

Hi Alexander,
I am running in to the exact same issue (although not with Linux). Did you ever find a fix for this? I have some support tickets open with my VAR's, but found your post and thought I would check. If I find anything I will post.
Thanks

Laptop connects to wireless network via a WRT54G but it can't access internet

I’ve got a WRT54G cabled to my desktop, I set up a WEP-secured wireless network for my laptop, and the laptop connects to the wireless network and receives a strong signal, but it can’t get Internet access. I know the problem is not with the router because the laptop CAN get internet access when it's cabled to the router. (So the problem isn’t an IP address problem—which I knew because I had to reconfigure the static IP of the laptop to get it to connect to the network in the first place.) I turned off the Windows firewall, Symantec virus protection, and Internet Explorer’s pop-up blocker on the laptop. The laptop connects perfectly to the wireless network and receives a strong signal, so why can’t it access the internet??
Linksys tech support couldn’t figure it out, so I really need your help. Thank you!

(because I wanted it to have the same static IP address as the router).
Just wanted to clarify what you meant in this post. If you entered the router's IP address as the static IP for the laptop, you would get the symptoms that you are describing. Try entering a IP that isn't normally used like 192.168.1.142. (That is assuming that your router IP is the default 192.168.1.1.)
If that isn't the issue, please tell me what ipconfig is returning on both the laptop and the desktop.

Wi-Fi connection issues since securing network

Hi all,
Hoping to get some solutions as I have tried to troubleshoot this issue with other posts and google searches. Here is my scenario :
I'm running OS Lion 10.7.5 on my MBP and have been connected to our home wi-fi for about 12 months on a connection that wasn't secured by password.
Since having some download issues and fearing that someone is connecting outside our household, we have secured our wi-fi and added a password.
Both mine and my sister's iPhones got prompted to select a network, selected the appropriate one, punched in the password and were connected with no issues. My iPad Mini, Dad's laptop and both my parents' phones all connected with no issue.
When I booted my MBP, I was prompted with needing to join a new network and upon selecting our home network was met with an immediate 'Connection timeout' response.
I try to connect manually through Network in the System Preferences and got the same 'Connection Timeout'. When I click 'Assist me' and try to connect that way, I am finally prompted to input the password, which I do correctly and I get 'Invalid Password' etc etc response ... then after about 5 seconds it connects me !!
So even though the connection timed out and I wasn't able to put a password in, manually doing it told me the password was wrong etc then I get connection like normal. If I switch my laptop off/reboot/log out/turn wi-fi off then back on, I'm back to square one and can't connect unless I follow the same tedious steps.
Fearing it was an issue with our router, we have since bought a new one, installed it and reconnected all the devices as mentioned above, however my MBP connection issue still exists.
How can I get it to connect automatically like it used to and recognize our home network with a correct password, without continually having to go through all those steps ?
I have tried to delete that entry in my preferred networks and tried to re-establish it etc. Keychain Access doesn't list my router and input password.
I'd like to be able to solve the issue asap if possible and hopefully without having to delete all of my other known networks that I connect to as I travel all over the country for work and have about 6-8 routers I connect to, depending on what city/office I'm in.
Any assistance would be appreciated !

Some users with various Wi-Fi connection problems have reported that they were given the following instructions by Apple Support, sometimes with success. I can't vouch for this procedure myself. After completing the procedure, you'll have to recreate all your settings in the Network preference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
Step 1
Back up all data.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 2
Reset the System Management Controller

Laptop connecting to Router but cant access intern...

Hi all, my girlfriend and I have recently moved into a new place and decided to opt for B.T Broadband. Our Home Hub 4 was delivered yesterday, and we set it up according to the instructions. Since setting up, my girlfriend has been able to get the internet working absolutely fine on her laptop (X.P), and I have been able to access it on my mobile phone (blackberry) and tablet (Android)
However, despite my laptop connecting to the router, it is refusing to actually allow me to access the internet. The router is displayed as an 'unidentified network' and the connection is local only.
Does anyone have any advice? I can't connect using an ethernet cable as my laptop's port is broken. I have tried performing a windows updaet but it doesn't seem to have done anything. Not a complete disaster but a little annoying, so any help would be much appreciated. Thanks!

Vista does have issues with WPA2 encryption. Could it be you weren't using that on your previous router? The BT Hubs default to that, so you could try changing the encryption type. There is a windows update for that which should have come down.
If it is showing unknown network, you could try setting a fixed address for the laptop if you only use it at home.
Press windows key and r, then type ncpa.cpl in the box that pops up. Then right click on wireless network. Select Internet Protocol v4 (TCP/IPv4) then press properties. Then on the next page select use following address for IP address and fill the fields with, as an example,
192.168.1.10
255.255.255.0
192.168.1.254
Then in the dns fields beneath you could use:
8.8.8.8
192.168.1.254.
Hit ok, then close and that'll get you back to the page that shows the wireless connection. It should have stopped showing unknown connection by now and hopefully, you should have a connection.
There are known issues with doing this on Vista, but the fix for this is readily googleable and not every user gets it.
