Help please - cannot get IP address
Hi everyone, I have a WRT54GS router with WEP encryption. I have 2 laptops, both with XP. I cannot get one of the laptops to get an IP connection. It connects to the router, but when I run ipconfig, I get the following error message Windows IP Configuration An internal error occured. A device attached to the system is not functioning. Please contact Microsoft product support services for further help. I have many years of IT experience, and I've also had my network admin brother help me, but we can't figure it out. I have entered the WEP address correctly and have unchecked the box "Key is provided for me automatically". The key index is the same on both PC's. We have released the IPconfig. The PC that can't connect has been recently acquired and has never successfully got an IP connection on this wireless LAN. Any suggestions greatly appreciated. Thanks so much, Lynne
Sounds like an issue on the computer itself not the network. You might need to uninstall reinstall your wireless card.

Help please--cannot get summary button to work???!!!!
Hi all,
I am trying to get a summary of results on a survey, and I did have a portion of it working, but needed to add more code to complete it.
When I hit the display summary button--nothing happens. There is a problem with my logic, but no logic errors come up. I must have created an infinite loop.
Your help is much appreciated!!!!!
Here is the code
rivate void summaryJButtonActionPerformed( ActionEvent event )
//declare variables
double perAgree = 0.00;
double perDisagree = 0.00;
double perNuetral = 0.00;
//calculate percent response for each category
perAgree = ((double)numAgree/total) * 100;
perDisagree = ((double)numDisagree/total ) * 100;
perNuetral = ((double)numNuetral/total) * 100;
//clear old results
summaryJButton.setText("");
//add header to output area
resultsJTextArea.append( "RESPONSE\tFREQUENCY\tPERCENT\tHISTOGRAM");
//display results
resultsJTextArea.append("\n" + "Agree" + "\t" + numAgree + "\t" + perAgree + "%" );
resultsJTextArea.append("\n" + "Disagree" + "\t" + numDisagree + "\t" + perDisagree + "%" );
resultsJTextArea.append("\n" + "No Opinion" + "\t" + numNuetral + "\t" + perNuetral + "%" );
do
if (numAgree < total)
resultsJTextArea.append("\t" + "\t" + "\t" + "*");
if (numDisagree < total)
resultsJTextArea.append("\t" + "\t" + "\t" + "*" );
if (numNuetral < total)
resultsJTextArea.append("\t" + "\t" + "\t" + "*");
} while (numAgree + numDisagree + numNuetral <= total);
} // end method summaryJButtonActionPerformed
/code]Hi and thanks for your help!
I did invoke the method with a handler. Maybe I should have given you the entire code that I have in the first place.
The first part of the code, and the other method seems to be working, so I was focusing on where the problem is.
By the way- tried the system.out.printli, but since nothing happens when I click the summary button, I cannot even get any values to print in the command prompt.
Here is the entire app:

Living in Dubai where many apps are blocked. How can I get around ? Tried to create a new Id but my billing address in Dubai will not match the criteria for an account in the US. Help please to get around the censorship...thanks
The censorship in regards to certain apps not being available in your country is by your country, not by Apple.
Due to various laws and licensing in each country, in order to have an iTunes store account in a particular country you must have a credit card with a billing address in that country. If this were up to Apple, there would be no such requirement and there would be only one iTunes store for the entire world, but various laws, regulations, and licensing issues in each country, this is required by Apple. -
HT4527 Help I cannot get home sharing on to my I pad
Help I cannot get home sharing to work on my I pad purchased yesterday
On your computer's iTunes you've turned on home sharing via File > Home Sharing, and in the Sharing tab in Edit > Preferences you have the 'share library' tickbox ticked (I use a Mac, but I assume that it's similar for PCs) :
On my iPad I'm logged into the same account via Settings > Videos > Home Sharing, both my computer and iPad are connected to the same network (and iTunes on my computer is open), and at the top of the Videos app I get an extra tab :

Please Help: I cannot get the Airport Extreme settings right with AT&T DSL
AT&T Motorola 2210 DSL Modem.
I have tried both bridged on/off and different configurations on the Airport Extreme, but I cannot get online. I am out of ideas. I called AT&T tech support and because it's not one of their wireless routers, they wanted to charge me to troubleshoot, ridiculous.
Please helpIf you find that the Double NAT setting will not allow the PS3 to connect correctly, your only other option is to change the configuration of the modem to either +PPP on the computer+ or +Bridge Mode+ and then configure the PPPoe service on the AirPort Extreme.
I assume that you have already set the modem up using the default IP address of 192.1681.254 (I think this is it). You'll need to locate the page to change the settings and it will probably have a red warning sign on it. Either PPP on the computer or Bridge Mode will work. Update to save settings.
Then under the Internet icon in AirPort Utility:
Connect Using = PPPoE
enter your user name (probably your email address with the service provider)
enter your password
Leave the Service Name area completely blank
Connection = Always On
Disconnect if Idle = Never
Update to save settings.
That will eliminate the Double NAT issue and the PS3 should get a clear indication. As I said, when you have the PPP connection on a device other than the modem, you may see an occasional drop and restart of your connection. That seems to be a fact of life with this type of setup. -

HELP: MacBook cannot get IP from DHCP wired/wireless
Hi, everyone.
I recently bought a TP-LINK TL-WR340G route and added it into my home network.
My iBook and PCs are albe to connect to network and internet, but my MacBook even cannot get a IP from the DHCP. I tried both wired & wireless connection.
I've tried to give my MacBook a static IP address, after that it can ping to the gateway and other devices on the network, and the DNS is working fine. But the MacBook just cannot connect to internet.
My MacBook can connect to internet at my office and my relative's house.
Please help to fix the problem. Thanks a lot.What is the device type?
I have seen this with 4 android 5 devices. I think its something to due with misconfig on android and mfp settings. Although I'm not sure why I have hundreds of other android 5 devices working ok. I see this same when I debug one of the devices that is stuck in DHCP_REQ

HELP PLEASE cannot install Mac Osx
hey I really need help please!
I tried to modified my dock using my resources folder in the dock components but I surely did something wrong cause when I tried to click on time machine, it said that I need the right osx version.
So I restarted my computer but it just wont start, i see the spinning gear over and over again. So i decided to reinstall mac os x tiger and to reupgrade to leopard afterwards.
I restart m computer, hold C, get to the install process and when I need to choose my volume, I choose my HD, the one in the iMac but its says cannot install on it because of a Volumecheck problem...
I really need to reinstall it without loosing my data on it I have some important photos for my work, I NEED THEM!
HELP!Hello and welcome to the Apple boards
If you have been using Time Machine, you can restore your system from it using the Leopard DVD and following the instructions on this link:
http://www.peachpit.com/articles/article.aspx?p=1091577&seqNum=6
You might first try booting from the DVD and repairing your HD first. The tools are in the Utility folder on the DVD
You boot into the DVD by starting the computer and holding down the "C" key.
Hope this helps a bit. -
Wireless clients cannot get ip address
I have 7 WLANs configured all work fine but the latest. The 7th WLAN I configured will not let clients get an IP address. I can plug a wire into the port with the same VLAN configured on the port and I get an IP address but wireless clients connected to an AP on that port cannot get an IP adddress. Any suggestions would be appreciated.
Hello,
where is the DHCP server configured?
- do all other 6 WLAN's work fine with the same DHCP server.
- do you have any H-REAP VLAN mapping , or AP groups configured?
they will override the WLAN-interface configuration.
Kind regards

This new updated firefox is awful.. I cannot get websites to open for about 10-15 mins it keeps showing S1 Yimg.com ans s.ytimg, and says shockwave plug in is bad, and all other kinds of crap..
The connection was reset.. I got this msg below and had to reopen this page in another window, and reload it to be able to write on this now... and my network connection is working xlnt, and there is no firewall blocking firefox...
The connection to the server was reset while the page was loading.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Try Again
I never had this until I got all these new automatic updates with this new firefox.. I did a system restore, which helped for 1 day, and I have had to reset firefox daily to use it.. And now it took 10 mins to open this page, and then I had to reload this page twice to write this..
I've used firefox for years, and never never had any problems with it. And I see alot of similiar complaints like mine on this forum now..
What suggestions do you have for me NOW... much appreciated, CyrusI uninstalled all the old flash players and installed the flash player v16.0.0.235 from the Adobe website posted.
And Firefox is still the same. It takes forever to web search, It takes a long time to get on Youtube, and a longer time now to open a video..
It's actual worse since I upgraded to the newer flash player.
I'll do one more fifefox reset (this is the 8th one in a week)
and it works for a few hrs, and goes back to the slowww way of working...
Many of my friends I talked to about this, told me to switch over to Chrome like they had to do..
I guess that's the only alternative now..
Thankyou all for your help and suggestions anyway.. :) -
Clients connected to AP541N cannot get DHCP address
New install with 3 AP541N's in a cluster. Two AP's are connected by an ESW-520-8P PoE switch and one on its own power adapter and a 3COM switch. I have set up a single SSID with WPA-AES encryption. I am connecting with HP 2740P tablets with Intel wireless cards. Clients can see and connect to the AP's but only some can get IP addesses from our Small Business Server 2003 DHCP server.
It's intermittent, some will get an IP and work for a while, while other can't. Then the ones that are working will drop and then none of the devices can get an IP. Then suddenly a few will start to work again. I have solid connectivity everywhere in the building but can't get an IP. Also, strangely, even when assigning a static IP I can not pass traffic, although it says I am connected with "5 bars" of signal strength.
Clients show up under Cluster>Sessions, but sometimes with really high counts of "Signal" and "Error Rate". However, even the clients with a "good" connection cannot get an IP.
Here is what I have tried:
Upgrade firmware on all 3 AP's to 1.9.1 (latest)
Wiped and reloaded the devices several times
Tried no encryption, WEP, WPA, doesn't make a difference
Tried everything described in this thread: https://supportforums.cisco.com/message/3078962#3078962 including the registry entry on the DHCP server
I have a spare AP that I put into production with the same load, but it didn't seem to make a difference.
Broadcast/Multicast limiting set to off
Upgraded to latest drivers on tablets; Boosted power on adapter to highest strength; Turned off power saving
I have exhausted all efforts in searching and trying based on my own experience, so any help the community can provide would be appreciated.
