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 connected to the 724 and the other thru the GS108).
I've been working with Netgear support as I bought a synology NAS which can link aggregate. When I went into LAG on the switch, the second part of the window where I would need to click on the ports to select them wouldn't show up. End of the day, I was sent a new GS724TPS today.
I disconnected the old GS724TPS from my rack and installed the new one. This is where I may have screwed up. I plugged all of my Ethernet connections back into their spots prior to first power on. I powered on and I couldn't log into the switch using my previous static ip or 192.168.0.239. Finally after an hour, I used the resource CD identifying program and I was able to hit reset DHCP and get the switch on to the same subnet as the router and then I could log in. I was able to set up link aggregation.
Ok, I then realized that I only had access to half of my network. Anything plugged directly into the router or switch was able to get an IP address in the 192.168.x.x range. However, anything connected through any of the 8 port switches would only get 162.294.x.x IP ranges. The 8 port switched are non-managed and I'm confused why the IP range is different. One of my apple APs is affected, so I went in and manually set the ip to be static and outside of DHCP but on the correct subnet 192.168.x.x. Well, it didn't matter as whenever I connect either ethernet or wirelessly to that AP, I'm still on the 162.294.x.x and can't access the internet or the rest of my network. I took the source ethernet cable out of the apple AP and plugged it into my computer and confirmed that the wrong IP (162.294.x.x) is coming from the "wall" and it's not an apple issue.
So, I went back to my equipment room, disconnected everything from the switch, reset the switch to factory default, and then rebooted with no connections and then only connected the router. I was able to guess the dynamic IP address, log in and change to a static outside of the DHCP range. I plugged my laptop into the switch and noticed for 5 sec that it gets assigned an 162.294.x.x IP but then it automatically gets switched over to 192.168.x.x Again, anything connected into the switch directly is on the correct subnet and can talk between themselves. However, half of my wired house and any devices connects to my second AP cannot access the internet or intranet. Oh yeah, my original issue of not being able to complete the second part of link aggregation setup has come back. I triple checked...no VLAN, DMZ or anything else setup.
I'm at my boiling point. Any ideas??

- 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. - Thanks for the reply. I will reset to factory again. I was hoping time would be the healing factor as I was away for the weekend...nope.
At this point I just want my network back up and the link is secondary - And yes...the entire network was up and running prior to me switching out the GS724TPS
- Update...up and running. Did nothing but a power cycle on the switch. However, the same issue for which netgear sent me a new switch is back. When I go to set up the LAG, under membership, the picture of the switch doesn't show up and hence I cannot choose which ports to enroll.
- What version firmware are you running - 3.xx with a yellow background - it's a little different to the older versions.
Create the LAG as step one and then go to membership there should be a yellow bar with a purple arrow pointing to the right - click the yellow bar - it should drop down and allow you to select the ports. - so I cannot post attachments yet but there is no yellow bar. There was the first time and setup worked. However when I lost had my network, I factory rebooted and no longer have the yellow bar now.
