Problem getting wireless device to show up

I have a Lenovo T61 thinkpad, and I'm trying to get wireless functioning on it.
Doing lspci | grep -i net gets me:
Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Apparently this is a well supported card and all that. I've loaded the iwl3945 module into my rc.conf modules list, and I've even modprobed it to ensure it's activated. Unfortunately, it refuses to give me a wlan0 interface. Whenever I do ifconfig -a or iwconfig or ls /sys/class/net all I get are eth0 and lo. I've tried adding the wlan daemon and removing it, neither seems to help. I have been hitting a brick wall for hours with google etc, so I figured I'd just ask. Maybe I am not searching for the right thing.

dmesg gives
iwl3945: failed to register network device (error -2)
If this is a problem with firmware, I cannot find any place on the wifi wiki that explains how to install it or where to get it from. All I see in the iwl3945 section is a warning that it needs to be installed. Since I can use this wireless card just fine on the Ubuntu partition, I figured the firmware was already installed. Is firmware loaded and unloaded every time the OS boots?
Edit:
OK so I just realized that iwlwifi-3945-ucode was the firmware, I have already installed this but had thought this was the driver package. Apparently the driver is already in the kernel by default. So basically, I am back to square one. There is something other than firmware and drivers that are causing this problem.

My devices no longer show up when plugged into itunes on home computer - How can I get the devices to show up on the left tool bar on itunes like before?

for some reason I can't see "devices" when I plug them into my home computer (running snow leapard). I recently upgraded my laptop to lion and now the devices are looking for my mac book. How do I get the devices to sync with home computer and not the mac book?

Problem getting bg image to show after integrating Web Gallery in page

Hi,
I'm new to Dreamweaver this year just coming over from the bad guys. I was looking to create a web gallery for my client when I came across a great article by David Powers that really worked well and made it pretty simple. (see here)
http://foundationphp.com/tutorials/gallery/embed1.php
The only problem I'm having is I want to use the background on the page I've created and not use a background color. In both CS4 & 5 The Bridge doesn't give you an option that I could find to insert background image which would have solved everything. Seeing as I'm inserting one page using iforms makes it a bit complicated and I've tried for a couple days but I can't figure it out. I'm more a designer then coder and when it gets to this part I hate it.
The behind the scenes page can be found here. I"m not sure why its showing white but in theory that shouldn't matter as the colours in the bottom I want replaced with my backround image the same as in 'trimworks'.
http://www.homeworks4u.ca/Trimmwork.html
This is my first posting.
I've done as much reading on css and figuring out how to do the web gallary I've run out of time!
Thanks in advance,
Sc.

I checked and flash had it set to opaque...so I tried windows and still nothing. I didn't really want to try the last option as that will reduce performance and the images are already high rez as it is. And this was done thru Bridge. You'd think there would be an easy way just to get a background in instead of the colours. Unfortunatly Flash is covering the entire area that my client wants the background showing....this was a last minute thing...just like the image gallary...we were all set for flash video show with his own tv set and all. Now he's mad cause I can't get a background to work.
http://www.homeworks4u.ca/untitled-7trim.html
Is the page where both pages are combined....including the image gallary...
http://www.homeworks4u.ca/TrimworksWG.html ( don't be fooled, view sorce)
This is the page The Bridge creates and then used Iframes to put it in the above page and want the background to show thru, not the dark colours.
The last one was close, but now I'm afraid with flash completely overtop of the background it could be hopeless. I'm on a time constrain. You all know how it is with clients with every changing ideas 3 days before launch which was last week. Any ideas at all at this point would be helpful. He just wants a photogallary that he can see his background thru! I"m willing to change programs at this point if I have too for something that easily puts the background in for you! I'd trade my time im for that at this point!
Thanks Everyone and Thanks Nancy!

Problem getting layers panel to show.

I cannot get the layers panel to show even though it is checked. Using CC 2014, OS 10.10.1 Affects all my Illustrator files.

The layers panel miraculously reappeared in all files. I have no idea where it was lurking while I was having the problem. I tried everything. But I seem to be out of trouble for now.
I have quite a few small unexplainable problems with my latest version of Illustrator and operating system. I don’t think they had their pencils quite sharp enough when they designed it all.
thank you for your interest and suggestions.
kind regards,

Why can't I get any devices to show in the sidebar of a finder window?

Until recently I had devices (hard drives, DVD's, disk images, etc show up under devices in the sidebar of a finder window. Now none of these items show up. In Finder Preferences>Sidebar>Devices I nave all 4 checked (Bob's Mac Pro, Hard disks, External disks and CDs, DVDs and iPods). I tried rebooting. I tried unchecking the 4 boxes and rechecking them to no avail. It's annoying that I have to find an icon on the desktop to open these items. Any suggestions?
This is a Mac Pro running 10.9.5.

Do a backup.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.finder.plist and com.apple.sidebarlists.plist. Move the .plists to your desktop.
Re-launch Finder by restarting the computer and test. If it works okay, delete the plists from the desktop.
If the same, return the .plists to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.

Problem getting blank DVDs to show up on desktop or in iTunes

Hello,
I have been trying to burn playlists in itunes onto a blank dvd. I can burn CDs, but when I try to insert a blank DVD, it checks media and spits it back out. Neither will my MAC show the blank dvd on my desktop when I insert it outside of iTunes. I have an internal DVD drive and an external one....same story!!??
The very last time I tried to burn a DVD in iTunes, it started, but then I got some strange message about the spool running out?? I've never seen it before.
My DVD drives are a Yamaha CRW2100E and a Pioneer DVD-RW DVR-1600D
Also, the drive keeps opening and closing...with or without a DVD in it. Again...it works for CDS!!!
I have verified and repaired my preferences. Any ideas as to what could be wrong?
Thanks,
John

Most likely your external DVD burner is causing a problem, disconnect it and reboot.
Try a different brand of media, handle only the edges.

Getting Avahi devices to show up in Finder with a customized icon

We have a device broadcasting out its model name "DeviceX" on the network:
<?xml version="1.0" standalone='no'?>
<!DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service-group>
<name replace-wildcards="yes">%h</name>
<service>
<type>afpovertcp.tcp</type>
<port>548</port>
</service>
<service>
<type>device-info.tcp</type>
<port>0</port>
<txt-record>model=DeviceX</txt-record>
</service>
</service-group>
According to this thread http://forums.macrumors.com/showthread.php?t=458047, on my Snow Leopard Mac I've copied our DeviceX icon .icns file into /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources . And then I'm supposed to add an entry into /System/Library/CoreServices/CoreTypes.bundle/Contents/Info.plist to map between the DeviceX model and this icon file so this custom icon will show up for our device in Finder. But there aren't any details for how to modify Info.plist to do this. Any help would be appreciated. Thanks!

Hi there. Having some problems getting my calender to show the correct days for birthdays I have in my contacts. If the correct date in contacts is the 22nd, then in iCal it appears on the 21st. Has happened on 3 occasions. All have been in the 20's ??

Hi there,
Having an issue where some birthday dates in my contacts appear as a different date in my iCal. One day before infact. Most are fine but three are incorrect. Seems to be all involving dates in the 20's. Have tried editing contacts but to no avail. Have read about syncing but because most are correct I am not sure about this. Very perplexed! The contacts dates are all correct.
Thanks for any advice.

TS1538 Is there a fix for this? How can I get it to where my device will show up in itunes without having to reinstall itunes every single time?

To get my Iphone 4 to show up in iTunes, I have to uninstall iTunes and then reinstall it EVERY single time I want to connect my device to iTunes. I've tried just using a wi-fi connection and that won't work. It's very annoying to have to go through all that trouble of uninstalling and reinstalling iTunes every time that I need to connect to my iTunes account. I first got this phone in Germany when I was visiting my uncle who was stationed there, he had got the phone from AT&T here in the U.S. while in Germany connecting to his computer to itunes was no problem, it'd connect without any issues. Then when I came home back to the states, my phone would no longer connect to itunes on my computer unless I unistalled and reinstalled, but my computer does recognize my device when I connect every time just itunes does not and I don't understand why it's doing that. Is there any way to fix this? How can I get my device to show up in itunes without having to reinstall it every time?

The ipod is not a backup device. The music sync is one way - computer to ipod. the exception is itunes purchases. Without syncing: File>Transfer Purchases
Copy everything from your old computer, or your backup copy of your old comptuer, to your new one.

Itunes and wireless devices no longer show up in upper right corner of itunes window

Help! My Internet service was interupted last week and when it returned my iTunes and wireless devices no longer show up in upper right corner of the iTunes window. I finally figured out how to get both of my wireless devices to show up on the left hand column under devices, but nothing else shows up now in the upper right corner! I cannot for the life of me figure this one out and the tech manual is not helping at all. Help!

If you have the left-hand sidebar showing then that is where the store and your devices will show can be selected - if you press option-command-S if you are using a Mac, control-S on a PC, then the sidebar should be hidden and the store and device should go back to the top right. Is that what you mean ?

Photos taken from iOS device not showing up on Macbook??????

I have photo streaming turned "ON" on my iPhone 5, iPad Air and Macbook Pro. For some reason or another I have been having problems getting the pictures to show up on my Mac. The only time I need for this to happen automatically is when I am listing on eBay. For example I took a picture of the item that I want to list from my iPhone 5. Within a few minutes the picture shows up my iPad Air. I am using my Macbook Pro to list the items. It took over an hour for one picture to come over. I called Apple and without having a device that is under the 1 year contract or Applecare they push this support forum on you or pay $19.95 for them to walk you through it.
Before anyone replies, I have made sure that I am signed in under my apple ID on all three devices and have photo stream selected as well. All of my devices are updated to the latest software. Being that I am having problems with my Mac it is version 10.9.4 running Mavericks. If anyone has any definite answers to this problem I am having I would appreciate all the advice I can get.

No offense, but there are not definitive answers when it comes to iCloud.
Reset iCloud.
On your iOS devices, tap Settings > iCloud > Photos then switch Photo Stream off then back on.
On your Mac open System Preferences > iCloud
Deselect the box next to Photos then reselect it.
Give iCloud a few minutes to re sync the data.

Missing Wireless Devices On DHCP Client Table

I’ll always have three wired devices connected on my router at all times and other wireless devices but I disconnect them when I'm done using them. I’ve recently left two wireless devices connect all the time but what seems after a week or so all my wireless devices stop showing up on my DHCP Client Table. Even though they stop showing up on the DHCP Client Table they still work fine and are still connected to the internet. I already tried rebooting my router and that seems to fix it. I have an E2000 Router with the latest Firmware: 1.0.04 I haven’t had any problems with disconnects or anything. My question is why is this happening and how do I fix it or does the router not support devices been connected for days? Thanks in advance.

There is no fix for this problem as it's not a problem. Maybe your wireless devices don't renew the lease at some point but just keep using the current IP address. Maybe it's a bug in firmware. But as you have noticed it does not cause connection problems. I think very often there are glitches in the DHCP table of various routers.

Firewire devices all showing "offline" in CS4

I installed CS4 Production Premium on one of my worskstations (HP xw8200 Win 7 64b) a couple of months ago and have been using it mostly just for outputting via Adobe Media Encoder. Today I tried for the first time to do an actual capture via firewire. Both devices I tried (JVC GY HD-110 camera and a JVC BR-DV3000 deck) gave me the familiar ka-doink sound when I powered them on, but the PPro capture utility shows them both as "offline". I tried rebooting the PC, doing a Windows update and checked both devices to make sure they were properly configured for output, but nothing has worked. I checked all the settings I could think of in PPro, too. The Windows Device Manager refreshes when I turn a device on or off, but I don't see either device showing up there. I realize this is probably a Windows issue, but I thought someone here might have an answer.

I used to have similar trouble getting firewire devices to show up. What I had to do was the following:
1. Unplug the firewire cable from the the pc and make sure the camera is off.
2. Reboot the PC with the camera off and the firewire unplugged so it boots up 'fresh'
3. Shut down the PC completely with the firewire unplugged.
4. With the PC shut down, plug in the firewire and turn on the camera to VCR mode or whatever you use when capturing.
5. Boot up the PC with the camera plugged in and turned on.

Wireless devices keep dropping, Wired works 24/7

Hi,
We have had bt infinity in our home for a few months now, and only in the past few weeks we have been having constant problems with wireless devices. We have one computer wired, one wireless and a few other devices such as tablets phones etc. The connection on all the wireless devices keeps dropping with no response, while the wired one is still working perfectly. The problem is becoming more frequent than ever, I spoke to tech support at BT who told me to log onto my router and change the channel to 11 but since then, zero improvements.
When i troubleshooted the internet connection problem on the wireless pc, i got the message
" internet connection doesnt have a valid ip configuration"
Can anyone help? or is my hub giving up the ghost?
Thanks!

There is some help on this page.

Hi

I have tried reseting the network settings and forgetting my wireless connection and re-connecting to it. I even backed up my phone on itunes and restored it, factory reseted it. Nothing seems to work.
Also after my upgrade to ios 8.1 my personal hotspot option under cellular data has disappeared.
Would you please help me out? I would really appreciate it.

Hi..
Restart your router then restart the iPhone to test.
