How to make trackpad automatically reconnect after sleep?

I have a magic trackpad and an MB Pro.
When I return to the computer after it has been sleeping overnight, the magic trackpad will not reconnect automatically. If the computer sleeps briefly, the connection is restored automatically. If the trackpad is powered off after sleep, it will reconnect when powered on. But after a long sleep, or perhaps when I have disconnected the laptop for a while I cannot easily make it reconnect.
It will not reconnect if: I click the power button, click the trackpad, select the trackpad by name and connect from the bluetooth menubar item, connect manually through bluetooth preferences, or turn off the trackpad entirely then turn it on again (force into discovery mode).
The only somewhat reliable way I have found to reconnect is: 1) turn off trackpad power, 2) go to trackpad preferences, 3) set up bluetooth device, 4) power on trackpad, 5) select continue when device is found.
When disconnected, in bluetooth preferences, the device is shown as being paired. I added it to Favorites. It is discoverable. Battery power is good.
I can reproduce the same symptoms with these steps: 1) put the computer to sleep, 2) manually turn off the trackpad, 3) turn on the trackpad again (it blinks, indicating attempt to discover), 4) wake the computer.
Can anyone help me find a less time-consuming way to re-establish a connection when the computer wakes from sleep?
Thanks,
Tom

Hi Jeff,
Thanks for the suggestion. I tried the 'root bridge' in Access Point mode but the remote devices did not try to reconnect. I also tried 'non-root bridge', 'root bridge with network clients', 'automatic' etc. I let it sit for a few minutes after each change to see if it helped.
I've going to change it to 'Access Point' again and leave it overnight to see if one of the three remote Workgroup Bridges that are currently unavailable will re-connect.
I know if I ask the site electricians to power the remote Workgroupd Bridges off and on they will connect for a while - its quite frustrating!
Thanks again

Wireless network does not automatically reconnect after sleep

I have a Belkin wireless G+ mimo modem router network. When I wake the mac from sleep it does not automatically reconnect to my wireless network and i have to manually select the network from the airport icon in the menu bar and then it connects without having to reenter my secure password. How do i set the mac to auto connect to the network after sleep? There are about 6 other wireless networks in range which may be effecting this reconnection.

In may case the network was already at the top of the preferred networks list.
Based of of a hint over at MacOSXhints.com, here's how I fixed this problem:
1. In the Network references pane, delete the Airport connection that does not like to reconnect.
2. Click Apply and Quit the System Prefs app.
3. Put the computer to sleep.
4. Wake the computer.
5. Go back in to the Network pref pane and re-add the Airport connection. Do not try to connect to the network at this time.
6. Click Apply and Quit the System Prefs app.
7. Use the Airport menubar app to connect to your network.
8. Verify connectivity
9. Put the computer to sleep.
10. Wake the computer.
11. Verify connectivity
My machine now consistently reconnects when coming out of sleep or restarting.
God luck!

Aironet 1310 - how to make it automatically reconnect

Hi,
We have deployed a number of IP CCTV cameras to cover a construction project. A number of them are connected using 1310s to provide a wireless link back to the main building.
The building access points are running in Root Bridge mode, the pole mounted 1310s are running in Workgroup Bridge mode.
They connect fine and work well. BUT when the line of site is obstructed by a crane, or a drilling rig for few hours/days, the link goes down. This is fine/expected, but when the obstruction goes away the wireless link stays down until we go to the remote pole and power off and on the 1310 - then it reconnects fine.
Restarting the building 1310 (root bridge) does not normally help.
Is there a setting to force the 1310 to auto-retry the connection every few minutes if the link is down?
Thanks for any help

Windows 7 brightness reverts back, wifi takes long to reconnect after sleep

Hi fellow members,
My brightness setting keeps reverting to max. I have tried setting via power manager and also from control panel.I can adjust but when the computer restarts, the brightnes reverts to max. It started happeing around a month ago. I didn't have these issues until about 2 months ago. I have had my x301 for over an year without issues.
Another issue I have been experiencing is that wifi takes a long time to reconnect after sleep. About 5 minutes. This is also a new issue.
I have the latest BIOS, latest power manager, all drivers are upto date. Here are the specs.

Check in the Windows power profile for the brightness issue. Windows will apply it's own at boot, then Power Manager will override, which leads to a momentary discrepancy.

How to make a category highlighted after it clicked

Hi there! Just want to know how to make a category highlighted after user click on it, so he will able to track on which category he is currently on?
I've already created 3 categories (links) through creating library elements, I already have the hover effect I made through CSS external stylesheet, everything works, but the category is not highlighted when I browse within it.
Here is my HTML code of these 3 links:
<td bgcolor="#663300">
<div align="right" class="link"><a href="index.html">Home</a>     <a href="Accessories.html">Accessories</a>    <a href="Contact Us.html">Contact Us</a>    </div>
</td>
And here is my CSS code for these links:
.link, .link a:link, .link a:visited, .link a:active {
    font-family: "Times New Roman", Times, serif;
    font-size: 18px;
    font-weight: normal;
    color: #FFFF33;
    text-decoration: none;
    padding: 5px;
    #home: color:#00FFFF;
.link a:hover {
    font-family: "Times New Roman", Times, serif;
    font-size: 18px;
    font-weight: normal;
    color:#FF0000;
    text-decoration: none;
So how to make the active link highlighted when browsing within it??
Thank you

How to make an before and after effects?

So, I want to make a video that show the audience this is before and after the edit. And i want to make it look like this YouTube Rewind 2014: Behind the Scenes - YouTube
How to make it?
Thanks:)

Really? You take footage of you shooting the video with another camera then you edit it together with shots of the finished project. If you want to show before and after shots of an effect you just put the original footage on top and animate a mask or opacity to reveal the rendered effect below.
If you can't figure out how to make a before and after then you will have a very difficult time doing any effects using AE because there is absolutely nothing in this before and after but very basic editing and masking.

10.9.2 upgrade and now wifi will not automatically reconnect after wake from sleep

I upgraded to 10.9.2 on my mid-2012 Macbook air and now when i wake the laptop from sleep the wifi will not automatically reconnect. I have to physically click on my network to re-join it.

Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
Remember networks this computer has joined
is checked.
2. Follow the instructions in this support article under the heading
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
3. Reset the PRAM.
4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
7. Repair permissions on the startup volume.
8. Turn off Bluetooth and test.
9. Reset the System Management Controller.
10. Reinstall OS X.

Solution for 'my mac will not reconnect after sleep'

After lots of trial and errors I found the way around the problem of dropped or very poor wireless connection after you put your mac to sleep.
I have no idea what the problem really is but this procedure has stopped me from throwing my brand new MacBook through the window.
1) Go to System Preferences -> Network -> Advanced
2) Remove any network you have there memorized
3) uncheck option 'Remember any network this computer has joined' (leave the other options also unchecked)
4) press ok and switch AirPort off ... then on (make sure you have 'Show AirPort status in menu bar' checked)
Now the only real change we've made is to stop Mac memorizing our network - but here lies the solution.
Put your MacBook to sleep and than wake it up. It will not connect to the network (none are memorized) but all you have to do is choose your network name from the list on the menu bar. It might ask you for the key but in my case it simply asks for permission to use my KeyChain (memorized WPA2 password).
Once I press 'Allow' .... it works as it should! eureka!
Do not check 'Remember this network' when asked for password.
As long as Mac does not store your network details it reconnects without problems, once you allow it to store these details, re-connection after sleep goes pear-shape.... figure it out Apple!
I hope this might help you (as it most certainly works for me)
best regards
ffar

I've run Keychain utility. I also removed (as suggested in various places) any entries referring to my wireless password in KeyChain and allowed them to be memorized again. It doesn't change a thing.
Please understand me correctly. My Airport does re-establish connection automatically (if network details are stored) but connection is extremely flaky, slow and with frequent dropouts. So the Keychain is not to blame here (I think).
If I establish connection 'semi-manually', as described in my previous post, it is perfect, just as it should be. This would indicate to me that the problem lies not with the Keychain, but in the way OS stores network details.
If I do not allow OS to keep network details - re-connection works.

Keyboard & trackpad not recognized after sleep

I have a brand new 2012 iMac with a frustrating problem, neither the keyboard or the trackpad is recognized after the machine has gone to sleep.
Once I unplug the keyboard and replug it in, it is fine.
Once I turn the trackpad on and off it is fine.
I can wake up the computer using the power button on the computer (but I still have to 'reconnect' the keyboard and mouse).
I've tried other keyboards. I've reset the SMC controller. I've reset PRAM.
Ideas.
Brand new system too... nothing funky installed.

Thanks for the note. I neglected to mention that I had already tried that download. I received the "This update is not intended for this computer and will not be installed" message. Didn't see where I could do anything with it further.
I also had the issue of my wireless/bluetooth trackpad not being recognized by the mac side when I re-booted. I've re-installed it but obviously don't want to deal with that every time I re-boot.

Firewire disk automatically ejects after sleep mode

I have Maxtor OneTouch Firewire drive that occassionally will automatically eject after after my system awakes from sleep mode. Usually just need to power down the disk and then power back up for it to reconnect, but sometimes that doesn't even work. I have latest firmware from Maxtor, but that didn't help. This is really starting to annoy me. Any ideas?

No ideas? anyone??

Slow reconnect after sleep

My early 2006 iMac takes a long time to reconnect to my wireless network after sleeping. It finds the network no problem just takes up to a minute to "wake up" and find and join the network. Is there any way to speed up this process? My Macbook connects about ten times faster after coming out of sleep so it has to be something with the iMac and not the network.
Thanks for any help.

How to make the document dirty after updating the links?

Hi,
I am using the below code to update the link resources by providing new URI. The link resources are getting updated, but the document is not becoming dirty.
                InterfacePtr<ICommand> updateCmd(CmdUtils::CreateCommand(kLinkResourceStateUpdateCmdBoss));
                InterfacePtr<ILinkResourceStateUpdateCmdData> updateCmdData(updateCmd, UseDefaultIID());
                updateCmdData->SetResource(ref.GetUID());
                updateCmdData->SetDatabase(ref.GetDataBase());
                updateCmdData->SetNotify(true);
                updateCmdData->SetUpdateAction(ILinkResourceStateUpdateCmdData::kUpdateURI);
                updateCmdData->SetURI(newURI);
                updateCmd->SetUndoability(ICommand::kRegularUndo);
                CmdUtils::ProcessCommand(updateCmd);
How do I make the document dirty after updating the resources?
Thanks,

Thanks. It is working fine.
I called PreDirty(docPtr), before updating the links.

How to make Finder automatically go to the foremost open window?

I hope I'm explaining this clearly.
Suddenly, when I click on the Finder from the Dock, it does not go to the last open window. I have to go to the Windows menu and select it, or click and wait on the Finder icon in the dock for it to open. I usually have a lot of apps open so when I go to Finder it's to do some file management - and the extra step of having to bring the last open window to the forefront is annoying me!
Does anyone know how to make the Finder automatically come to the forefront (with the windows) from click in the Dock? I swear my mac always did that before but now it's stopped!

can anyone help me here?
