I have a new MacBook Air and my wi-fi connection has to be manually selected after wakeup. The issue started after the Mavericks OS X 10.9 upgrade.
MacBook Air, OS X Mavericks (10.9)
I had this problem too on my late 2013 MBPr 13" running Sierra. No auto connection to my known wifi networks at home except with Bluetooth off. The solution posted by idrisser/izaakm seems to have worked for me.
Test after taking each of the following steps. 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.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. 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.
4. 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.
5. 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.
6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
7. Reinstall OS X.
Also try deleting /Library/Preferences/SystemConfiguration. Restart the computer and then connect manually. After that it should reconnect after restarting or sleeping.
I have the same exact thing as OP. Never had a single wifi-related problem in ML. I've tried basically every single fix mentioned in this forum. Apple, you broke my computer! Now fix it already!
See the post here that fixes this problem. I had the same issue, now it is working.

I'm running 10.9. Here is my fix:
hope it helps. with bluetooth off doesnt bother me as much as not having wifi auto reconnect after sleep mode.
I have the same problem with my 2013 MBA. It's a real pain. It seems that the problem doesn't happen if bluetooth is switched off but I have found no proper fixes.
I've been on support with apple for hours and they have no clue how to sort it and don't acknowledge it as an issue.
I agree with @Slihousttes that it's less annoying to have to turn bluetooth on and off all the time, but this is still a real pain and not what you expect from Apple. I hope they pick up on it properly and release a fix soon.
I have same problem with macbook air.Recently tried this and seems to work......just by chance...no great knowledge here.
Went to Airport Utility
Select (Time Capsule/Aorport Extreme)
Hit Edit
Select Wireless from list of options at top
Select wireless options on new screen....towards bottom
Change to 802.11n
Seems to have worked for me
Thanks Paul. I did try changing my router to 802.11n but it didn't solve the problem for me. It's also not an option for many.

if you go into system preferences to change the settings, first make sure it is unlocked so that changes are available and can be made.
go to system preferences
click on network
make sure lock is unlocked (bottom left corner)
click advanced (bottom right corner)
under wifi option (click your network and manually drag it to the top of the list): it joins networks in the order listed here, so if you put yours at the top it will join that first.
click apply settings
click the lock again (bottom left) to lock changes
hopes this helps. shouldnt have to reconfigure beyond this as suggested by some other posts, this should be the simplest option first.
I am having this same issue after the most recent Mavericks upgrade and have tried all the fixes I have found so far (add/remove network, change priority order). I don't use Airport. I'm mainly posting here so hopefully Apple will see many people here have this problem - and if anyone knows another fix please let me know! It's really annoying to have to constantly turn the wifi off and on - I work from home and now must do this at least 30 times a day!
I started to have the same problem on March 27, 2014. Everytime my Macbook Air (Mid 2012) wakes up from sleep, it scans for available network but does not connect to anything. Sometimes, it doesn't even see my home network. I have tried everything from rebooting to deleting and setting up the network again to chainging the priority order of my home network to the top. Apple needs to fix this with its next update.
Thanks simsjaso, but this doesn't work. It's a more fundamental bug in the system not linked to simple config settings like this. Trust me, I have tried EVERYTHING including hours on phone with apple support, two full system restores and a new wireless card. It is a bug that apple can't currently be bothered to fix. 😠
Thank you, this works! For now at least.
Will I have to redo this for all my saved networks? And how long does this fix work for? Did you notice any issues once you turned the blue tooth back on? Thank you again!
FYI - this issue started for me after I installed mac osx 10.9 on my macbook air 13-inch, Mid 2012
For me the problem only occurs when bluetooth is switched on. I use bluetooth all the time so turning it off is not really a fix.
Every time my new macbook air wakes up the wi-fi connection doesn't automatically connect even though I set it to auto connect
