Trouble conecting to Time Capsule

[slippyjim]

Hi,

I'm a PC man, but as the general computery guy I was asked to help a friend with a Mac problem.

He has just moved to a new house, the old setup was 2 macs, a desktop running OSX 10.10.5 and a laptop running OSX 10.9.5 connected to a time capsule (I think by wifi, he's not totally sure) and everything backed up fine, but not any more.
In his new house the router (HGW-2501GN-R2 movistar fibre optic) is on the ground flour, and is connected via LAN cable to 3 movistar routers that at being used as Access Points, one for each floor of the house. The time capsule is downstairs along with the desktop mac. the desktop mac backs up absolutely fine no problem whatsoever whether its connected via LAN or wifi, the laptop on the other hand...........

At first the laptop refused to even see the time capsule unless it was connected directly into it via a LAN cable, but I have now got it to the point where I can connect to the main router via wifi and when I open the Airport Utility it displays internet with a green dot and also Time Capsule with a green dot, so then I go to Time Machine, it finds the disk and says "preparing backup" and then it stays on that for ever and after a while the Time Capsule with a green dot changes to Time Capsule with a yellow triangle. Before the green dot changes to a yellow triangle I can actually open time machine and go back through the various dates and view the original files, but after it changes to a yellow triangle when I open time machine I just get blank windows.

What is going wrong?

I have enabled uPnP in the main router.
I tried a different Access point, but it was the same.

Originally the desktop was on "home" network location, and the laptop was "unknown" (? I think, cant quite remember) so I created a "home" location and that did seem to help. I really dont know what those locations do, if anything.

The more I think about it I think its something up with the laptop and nt the network or the routers

Thanks

Connect a LAN port on the router to the WAN port on the Time Capsule and use Airport Utility to set the router mode under the Network tab to "Off - Bridge Mode".

You then should be able to see the Time Capsule disk in Finder on the Mac. Open a Finder window and look for it in the sidebar under "Shared". If it is not there, pull down the Finder menu to Preferences, click on the sidebar tab and make sure that "Connected Servers" is ticked under "Shared".

If you are using and antivirus program, you should make sure the Time Capsule is excluded.

I would suggest you do the next backup by connecting by ethernet. Once you get a good backup, you should be able to do incremental backups by wifi.

Try leaving it running overnight.

If it is still stuck on Preparing Backup, post back here for further instructions.

The Time Capsule is already set to "Off - Bridge Mode".

I think he does have Avast on the laptop, so maybe that is causing problems. I'm going back later so I'll go through what you've said.

Cheers

I think he's got it sorted now, someone who knows more about macs went over.

thanks anyway
