Macs drop off and won't connect to BTHub - Macs an...

We've got 2 Macs in our house which keep dropping off the BT Infinity Broadband hub and won't connect again
here's the thing:
The macs work fine on all other broadband at other locations
The other devices in the house work fine
It's just the combination of Macs and and our home BTHub broadband
recently it's got worse - the last few days more often than not the macs won't connect
We've tried
1. turning macs on and off
2. resetting macs
3. turning BT broadband hub on and off
4. turning the Mac airport wifi on and off
5. in network settings tried both automatically set to BTHub and manually.
None of this has worked.
This is so weird.
Any ideas?
Solved!
Go to Solution.

Separating the 2.4 and the 5GHz works straight away.
Go to bthomehub.home on a device that will connect (your phone will do fine)
Advanced settings
Enter the admin password from the card on your router
Continue
Wireless
5GHz
Sync with 2.4GHz: No
SSID: add a 5 at the end so you can tell the difference
Hit apply
Now forget the network on your Mac (System Preferences-Network-Wifi-Advanced)
There should now be two versions of your SSID in the list (the original and the one you added a 5 to)
Your mac should correct straight away to the 2.4GHz (so without the 5) but you'll probably need to put the password in the first time.
It's apparently a known fault in Macs that they struggle with the 5GHz internet
Good luck, if any of the steps are wrong please correct folks, this was very very frustrating for a long time and actually only took 5 minutes to fix!!

After upgrading to mavericks my mac shut off and won't come back on

I upgraded to Mavericks and my 2013 macbook pro shut off and won't come back on. When I push the start button I can hear the chime and then my sleep light blinks really fast and then shuts off completely. All I get is a white screen with the loading circle just going around and around. I tried resetting the pram but that didn't work. Any ideas?

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:

Apple tv2 movie rental cache drops off and won't finish downloading (not related to internet connection)

I'm having an issue with my apple tv2 when renting movies. This isn't with home-sharing but just renting movies only with the apple tv. We've done this with 10 or so movies up until the issue so it has worked in the past.
What happens is that the movie downloads to a certain point and then the cache bar goes immediately to the end of the progress bar like the whole movie is downloaded. The movie will play to a certain point, say the 9 minute mark, and then the picture just freezes with no more sound but the progress bar tracker continues along like it's still playing. This has happened on multiple movies now.
We've spoken to support about this and tried a variety of troubleshooting ideas. Unplugged, reset, restored, updated firmware, etc. with no luck. The download will restart but freezes at the exact second that it did before while showing that the cached download is complete. We've checked the internet connection with other devices and there's no connection problem at all. Reset the router as well for good measure but no change.
I know we can try renting and downloading on the computer first and then sharing with the apple tv but I would prefer to know why it's not working on the apple tv itself.
Any ideas would be great.
Thanks

Yeah, that's what we thought too so we got a refund (by using the report a problem link and explaining what happened) and tried a different movie with the same result. Used the link again after the second movie didn't work and went through pretty much the same troubleshooting steps with them.
Basically the only solution offered so far has been to take it to a licensed apple retailer for them to take a look.

I have the new iOS 6.1.2 on my iPad. My wifi connects to my home network but keeps dropping it and won't reconnect. Did not have this problem with previous iOS.

I have the new iOS 6.1.2 on my iPad. My wifi connects to my home network but keeps dropping it and won't reconnect. Did not have this problem with previous iOS. Apple, you have a quality assurance issue. Don't be like Microsoft where they send out pieces of junk with testing it.

Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Web part created on a subsite for a sharepoint list in another site using sharepoint designer, to show only the subsite's reports. Connection dropping off and showing all the reports

I crated web parts in the sub-sites (we have about 10 subsites) using sharepoint designer from a main list in another site. Then used web part to show only the ubsite's reports - using connection to the main list. Problem is, the connection
is dropping off and showing all the reports on the main list that are confidential. this has happened 3 time lately. Could someone explain why it happens some times? I had to fix it by adding the web part again and connecting it
Thanks, Subathy.

Hi George,
If you want to use a top level site "department" list column in all sub-sites, you can go to top level site and create a
lookup type "Site column" to look up the value from the department list, then all sub-sites can use this lookup type site column created in top level site.
Thanks

I forgot my passcode, so I was unable to access my phone. I then tried to restore it, but it has frozen during the process. It won't connect to my mac again and I can't stop the process because my lock button is broken. What do I do?

My first advice is "Back up the device, then have it replaced." Second item of advice, "Don't forget your passcode."
One of the purposes of the lock button is to recover from certain software failures. Without the lock button, such a recovery is nearly impossible. My advice would have served you best when the malfuction first developed, not after you forgot your passcode.

My airport says self-assigned ip and won't connect to the wireless internet.

My airport says self-assigned ip and won't connect to the internet. It's set on Using DHCP, and nothing has changed router/internet wise. I tried it with the firewall off as well, but it still doesn't work. The ethernet works, and I tried setting the ip address manually to the same one as the router. It said it connected, but when I tried to load pages, etc. safari said I was not connected to the internet.
I also tried doing system updates and updating the airport utility - still nothing.

My iphone 4 won't connect to my mac. It says that I need to install the lastest version of itune (11.1) but when I try to update itunes it says that I have the current version 10.6.3. Can someone please help!

Hi,
My iphone 4 won't connect to my mac book, it says that I need to install to latest version of itunes 11.1. When I go to itunes and try to update, it says that I have the latest version (10.6.3). Can someone please help me!
thanks

You are probably running OS 10.4 or 10.5 on a PPC Mac. No version of iTunes higher than 10.6.3 is available for these older Macs. I have the same problem, and while I can still use the PPC to sync my iPod, it can't be used to sync an iPhone 4 or higher. The only solution, as I discovered after upgrading to the iPhone 4, is to buy a newer Mac. I was able to get a 2006 MacBook running Lion for under $300, and that has been a lifesaver.

Macbook Pro - WiFi turns OFF and won't turn back ON

Hello,
this is my first time posting something on this forum; I will be as detailed as possible. I bought a Macbook Pro back in 2011 and It came with Lion OS. Last year I upgraded it to Mavericks and so far it has been a nice experience. However, in the past week I have experienced a very strange and irrating problem with my macbook. While doing work all of the sudden the WiFi would turn off and lose all connection to the web. I attempted to turn it back ON by clicking on the wifi signal icon but something weird occured, it was still 'ON' according to my mac and the only option available was to actually turn it OFF, so i clicked on it and the icon would go empty with no curvy lines (i attached a picture). Then i clicked again on the icon to turn it back on, however, as was doomed to remain in this state cause no matter what I tried.. the wifi will remain off even after clicking on the 'turn wifi on' option multiple times. I tried going to the assist me option under network preferences and I obtained multiple results with no fix. I tried sending my mac to sleep though at first seemed to fix the problem.. the wifi inmediately went back to being off and wont catch a signal. The only thing that fixes this is a fresh restart which is annoying and unacceptable...this is really annoying and I need a solution asap because this problem is become very frequent (once every 2 hours)... any help will be appreciated it.
I attached 2 pictures and the console log when this happened.
1. A picture of my assist me window before i sent it to sleep, shows the WiFi on the left with the 'Failed' (which confuses me). it also shows the wifi icon empty ( like it was off) but the computer shows as if it was on and would ask you to turn it off... weird?
A second picture after I sent my mac to sleep. Though it seems like there was no wifi signal available, the router was on and literally next to my mac...but my machine wont catch up the signal. (other devices were connected to the wifi and have no problem with it).
Here is the console log right before and after my this problem occured:

Thank you for your detailed troubleshooting attempts. Very helpful. Sorry, I cannot read "logs." My eyes just glass over on those things. Hopefully, a knowledgeable user will come along shortly to decipher for you.
I noticed from the pics that your location setting is "untitled." Have you tried the "Automatic" setting? Run the diagnostic test? Results?
Try the basics first:
   Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.

Ipod stuck in lock mode and won't connect to Windows computer

My Ipod is stuck on the lock position and won't connect to my computer when I plug it in. The hold switch moves back and forth just fine and it was working perfectly yesterday. It's the classic nano that's square. It's stuck on a song that I used as my alarm yesterday morning. I haven't turned it on since then and when I pushed the on switch, it went to the screen but then wouldn't do anything else. I've tried to hold down the menu and middle button while moving the hold switch, but it didn't work. Please help!

I fixed it! I had to switch the hold button from on to off to on again and then held the menu and middle button down at the same time. It works just fine now!

Hello untech,
I see that it has been awhile since you have posted with us on the HP Forums. Please let me take a moment to say "Welcome Back".
I see that you are having an issue with the printer shutting it self off and not powering back on.
By chance do you have the printer power cable connected to a power bar/strip? If so, please try connecting the printers power cable directly to a wall outlet. Here is a document that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
The printer in the document is a LaserJet printer but this document is meant for HP products in general and only uses the LaserJet as an example.
I am also going to include a document for when The HP Printer Won't Turn On or Respond When the Power Button is Pressed.
If by chance the issue is not resolved after doing the steps outlined, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.
Please feel free to write me back if you have any other questions.
I hope you have a great Monday.
