Help - half of network is on wrong IP address
I have a FVS336Gv2 router into a GS724TPS switch and then a couple non-managed 8 port switches (GS108 x2 and a roswell) and two apple extreme wifi routers in bridge mode acting as APs (one directly c...

First - a 169.254.x.y address is what is known as an APIPA address - an automatically provided ip address - and is the result of your having the system set to get a DHCP address and the DHCP server not being available to lease one.
So - the 169.254 is not an apple issue, it's not "coming out of the wall" - it's generated by the device itself, because it can't communicate with your DHCP server - you're losing connection somewhere and it seems to be between the 8 port switches and the GS724 and you need to find out why - was this working before you set up link aggregation?
What I would suggest is that you reset the GS724 to factory default and just set it's ip address and get the base network back up and then try to reconfigure link aggregation again.
One last thing - and I know you don't really want to hear this - do you really need the link aggregation? what's it going to do for you?
Don't get me wrong - if it's offered as a feature - it should work as advertised, but in a SOHO/SMB environment it's rarely necessary, and I'll take a bet, your Synology NAS can't saturate a single gigabit link, and that's pretty much the only time LAGs make sense.
FWIW - I'm running a LAG between my GS108T & FS728TS switches, I also have a LAG between the GS108T and an older IBM server (which is rarely powered up - fans are too loud) and I do have a new ReadyNAS, and I would have loved if that had dual gig ports, and if it did, I would have a LAG there too - but do I need any of them - no - would my network be any slower if I didn't have them - no - would my network be any less reliable without them - aaahhh - to be honest, given the headaches they have created (like you're having now) - it would probably be more reliable without them.
