N73 can't detect operator network

hi,
i recently swapped the sim from my old n73 to a new phone. recently i tested it back on the n73 and keeps showing offline although ive placed the sim card back. i tried changing the network to auto and changing the profile to general but it still doesn't detect the operator network. when i swapped it back to the other phone, it automatically detected the operator network. what's wrong with my n73?

Which firmware version is on it? Because that was the behavior with first firmware version. Check for a firmware upgrade and you solve that. But to sort right now, you must format the phone.

That must be frustrating.

Windows Can't Detect Wireless Network

I have a windows xp laptop which can't detect the wireless network i've created with airport express- but it seems to be able to detect other networks around the area.
My two other machines (one macbook and the other xp) does pick up the network.
It seems like everything is working fine. 2/3 computers can pick up the signal, but just one of the computers can't! And i've repaired and reinstalled the driver for the wireless card, but it just won't detect the airport express signal!

That link does not help.
The network card on my windows xp machine works fine. It can detect other networks in the building and works at other WiFi spots.
I think its something to do with somthing in XP and Vista that is preventing it from detecting Airport Express' signal.
I've increased signal robustness- still doesn't work.
I've removed the password- still doesn't work (obviously not a security problem).
I've updated the software- still doesn't work.
I'm very confused as my XP machine did detect it initially and connected to it successfully earlier this year, but it doesn't anymore.
It seems like the network can be detected by some windows machine but not others???

Spectrum Expert can't detect Wireless network and show SNR info

Hello,
We are using the version 3.2.163 of the Spectrum Expert on a shared laptop. I was able to see SSIDs under Active Devices and get display in SNR chart before. But recently for some reason, I can can't get SSIDs and only get interfering devices listed under Active Devices and got nothing deplayed in the SNR chart. I could not trace back what has been changed and double checked most of the settings, still not luck.
I appreciate any suggestions to get this fixed.
Thank you!

Humm, no comments from the experts?
Ok, I will give it a try.
I have SE 3.3.53 connected to a version 1 sensor card, loaded in a Compaq nw8440 laptop with an Intel 3945ABG nic.
Win7.
Spectrum Expert Sensor card provides the Analog RF energy data. Only.
The 3945 provides the digital network information via the windows API (WZC in XP) (WLAN AutoConfig in Win7).
Various windows patches and updates have interfeered with the ability of third-party applications to intercept or latch-on-to the data from the wnic.
SE no longer hears my 3945. However, I plugin a Cisco/Linksys AE2500 usb unit and presto Active Device data appears.
Interesting feature is that when I remove the USB wnic, the data link established attaches to the onboard wnic data stream.
On my XP desktop I use SE 4.1.11 for SE Remote.
The digital link is also broken, with everything I try. But then you don't want/need Active Device data from your house when your remoting to a distant shop.
I don't understand why the 3502/3602's can pass digital info right along with the analog data.
So in your case maybe installing another wnic might help with your issue.

Airport card can't detect wireless network

I just installed a new Airport Card (bought thru 3rd party seller) in my Powermac G4/933 and it won't see my wireless network. I have a Belkin wireless router and my Powerbook G4 with Airport Extreme sees the network fine. Is the old style Airport Card not compatible with my network for some reason? Any help appreciated.

Do you have your Belkin configured so that it will not broadcast the SSID? If so, you will need to go to the AirPort menu, select "Other..." and type in the name of the network.
Also ensure that your Belkin is operating in an 802.11b compatible mode.

IPod Touch suddenly no longer can connect to Wireless Network.

Hello, I have yet to find an answer to my problem so maybe you guys can help.
I have had my iTouch for at least 2 years and have never had a problem with it, and constantly used it to connect to the wireless network in our home.
However, starting two days ago, my iTouch can rarely detect the network (even when right next to the router) and if it does, it is unable to join because it loses the signal almost immediately. After much troubleshooting, (laptops connect fine, friends iTouch's connect fine) I have determined that something is wrong with mine.
The only thing I can think of that happened that day, was that night it had gotten extremely cold. (Montana, oh yay.) Could this have caused the malfunction?
Any insight would be appreciated!

Given that it got really cold and you brought it inside, condensation could have formed on the inside bits. Dump it in a bag of rice or a jar with those silica gel packages for a couple of days and see what happens.
If you still have problems connecting, try power cycling your router and resetting your touch's network settings.

Can´t see my Networks adapters in the Device manager!

Help!
I´m using Yoga 2 pro/windows 8.1
I can´t see the Networks adapter in the Device manager?!
(and no internet/WIFI connection is not working any more)
I´ve tried to install the latest Wireless Driver from lenovos homepage but it there is still problems. The laptop still can´t find any network adapter and the wifi connection doesn´t work, as it did last week!
Any one who has the same exeperience/or knew how to deal with these kind of issues?
/Rasmus

hi Rasmus,
Can you try these steps:
1. Check if you have a Network Controller entry in the Device Manager and follow this guide to get the hardware ID and on how identify the device.
2. If there's no Network Controller entry in the Device Manager, then it's possible that the Wi-Fi card might have been disabled.
Things to try:
- Boot into the BIOS either by pressing Fn+F2 on boot-up, the OneKey Recovery button, or via the UEFI Firmare Settings.
- In the BIOS, navigate to the Configuration tab and disable the Wireless setting hit Fn+F10 to Save and Exit then shut off the machine.
- Boot back into the BIOS and enable the Wireless setting then hit Fn+F10 to Save and Exit and observe if you can now detect wireless networks.
Let me know how it goes.
Regards

How can i detect if my PC is not on Network..... Urgent Pls Help Soon !!!!!

Hello Everyone,
We all know whenever we try to connect to a PC which is not on network, we get UnKnownHostException etc..... by which we can detect that the corresponding PC is not an network(intranet/internet)
But when i send a msg from my PC to my PC, it works fine even if the network is down. I hv provided my PC's IP address instead of using localhost or 127.0.0.1 which reduces the possibility that the msg will not be traversed thru the network.
Any IDEA how this works.
Is There any possible way by which i can detect that my PC is not on network or the PC to which i'm trying to connect is not on network .......
Pls help me out, its really urgent as to be implemented in my Project
Thanks In Advance

Setup can't detect network printer Photosmart C7250 all in one

I volunteer for our local historical society. The person who did a lot of the computer maintenance work is not active at this time so I’ve begun to look at things.
There is a Gateway PC running Windows 7 64 bit home premium, a Sony Vio laptop running Vista 32 bit home premium, an HP Laser printer and (of most importance here) an HP Photosmart C7250 All in one printer.
Internet connectivity is via a dsl line with a combination modem/router. I think the modem/router is a Westell or an Actiontec through Frontier Communications (formerly Verizon in this area) but I’m not sure and I’m not at the museum now.
A couple of weeks ago I was able to connect the laptop to the network via wifi. My next step is to connect the laptop wirelessly to the printer so we can print wirelessly over the network. The printer was originally set up through a usb connection so I changed it to a wired Ethernet connection. The PC now successfully prints to the printer over the network. I downloaded the software and drivers directly to the laptop from the HP site and began the installation. When it got to the point of finding the network printer the software couldn’t detect it. I then put in the ip address for the printer (from the network info printed out from the printer) and it still couldn’t find it.
This same situation occurred when I tried to set it up on my personal laptop (Win7 , 64 bit) as well. Setup couldn’t detect the network printer, even after searching for the network ip address.
Since the printer is connected to the network (router) via an Ethernet cable, I don’t have the wifi radio turned on in the printer. This shouldn’t make any difference.
I’ve searched the forums and haven’t seen anything that is like my issue.
I don’t what else to do. Hopefully someone will give me some advice on what to do next.

Download and run this utility: http://h20180.www2.hp.com/apps/Nav?h_pagetype=s-926&h_lang=en&h_client=s-h-e17-1&h_keyword=dg-NDU&ju...
What does it say?
If the network has Wireless Isolation turned on it will prevent wired devices from seeing wireless devices. Do you have access to the router?

Installed AE to iMac G5 but still can't detect network

Sorry for another thread but I've been searching the forums for this answer.
I installed an Airport Extreme card on my 1.8 Ghz PowerPC iMac G5.
After installing the software and updating all my software, I still can't find any networks on my Airport Extreme card. I have two other Macbooks and they are able to detect networks from my Airport Extreme Base station and also detect the neighbor nextdoor.
I can't seem to find a signal to any networks or connect to them. Please advise to what I need to do to get my iMac to detect my wireless networks.
Thank you

djriddler, Welcome to the discussion area!
The antenna wire connects pushes into the card farther than most people think. Compare your installation with the photos in KB 108039, Properly attaching the antenna on an AirPort Extreme Card.

Can't detect a German PC wireless network I know is there

Hi,
I'm new to this forum and I hope someone can help me.
I'm visiting friends in Berlin from Canada with my Powerbook G4 with OS10.4.11. I can't detect my host's wireless network even though I can detect 24 other wireless networks in her apartment building (I downloaded MacStumbler and used it to check). I know her network ("Jenny") is not hidden because she got a friend across the courtyard the same apartment building to check if she could see it on her computer this morning, which she could. I also tried to find "Jenny" by clicking on "Other" and then entering "Jenny" in "Network Name" and entering the WAP password my friend gave me (I also checked that with her so I know it is right) under both WPA Personal and WPA2 Personal. That didn't work either. I also followed advice on this forum and got rid of that stupid pop-up box saying "Your Network Settings have been changed by another application" when I clicked on System Preferences/Network
What should I do? All my friend knows is that she has a PC, she doesn't know the brand or model of her router or her ISP provider. If I can't solve this, I will be in big trouble as I had planned to stay in Berlin for a few months using my friend's wireless network to get online every day. I can get online fine via her router when I have a cable plugged into my computer in her flat, but I am staying across the courtyard in their second flat and we can't string a cable across the courtyard... I've never had problems before connecting with any PC wireless network, in Europe or N. America.
Very grateful for any help.

It won't let me do that. When I go to the Network window of my System Preferences, it says Location: Automatic, and it won't let me click on New Location or on Edit Locations - they are pale grey.
Also, it says Show Network Port Configurations and it gives me six: Internal Modem, Airport, Bluetooth, Built-in Ethernet, Built-in Firewire, VPN (L2TP) whatever that is, and Ethernet Adaptor (en2), and I don't know if that is the cable from my friend's router or the new stick adaptor I bought (it doesn't change, whichever I have plugged in), but all these are also pale grey and I can't click on them or on the boxes marked New Rename Delete or Duplicate.
Also the stick adaptor I bought is not showing up in my Finder window as an attached device - shouldn't it? This means I can't eject it safely when I want to. There are no instructions enclosed with it or on the manufacturer's website.
When I click on Network Status with the cable attached, it says I am currently connected to the Internet via built-in Ethernet with the IP address 192.168.0.112 so I guess built-in Ethernet must be the cable. So if the Ethernet Adaptor (en2) is the adaptor stick, maybe it isn't being recognized by my computer because it is on channel 13?

I can detect other network except for my own network, weird thing is I alone can't detect the rest can

I can detect other network except for my own network, weird thing is I alone can't detect the rest can. I can see all my friends networks and connect to them, but I cant see mine.

Try to re-position the router or your computer.

How can I get applications to detect a network scanner?

Running 27" iMac with OS-X 10.7.2, all Software Updates are installed.
Epson Workforce 630 attached via ethernet network. Driver is current at 8.61.
System Preferences>Print and Fax lists the printer and has a tab for the scanner. Scanning via this interface works fine.
Preview will detect and scan without problem, but Image Capture does not detect the scanners. Adobe Acrobat Pro 9 and Pro X do not detect my network scanners. Adobe support is no help. No problems with Apple products appear to be theirs, ever.
Epson drivers according to their website are installed through Software Update -- current.
But Acrobat will not detect the Epson over the network.
Note that my wife's iMac OSX 10.6.8 has the same problem.
Anybody got a clue?
Thanks!

You may be paying extra but what speed are you actually getting? Open Activity Monitor, click the Network button at the bottom and watch the Data received/sec speed while you're downloading different things. That will give you the actual transfer rate, not the advertised transfer rate.
Something like Adobe Flash shouldn't take long because it's only about 18 MB; how big is something that seems to lag? Is your internet connection wireless or are you using an Ethernet connection with a Thunderbolt to Ethernet adaptor? Wired is almost always faster. And with Mavericks being over 5 GB, it'll take a while under the best of circumstances, especially since the transfers I've observed of it don't run anywhere near what a fast connection is capable of.
