hey guys, so i had a networking consisting of this:


my ac87u router to a switch which has 3 seperate cat 5 to 3 more ap's which daisy chain to more ap's


i have a total of approx 9 access points in total


so this setup had been working perfectly fine for the past year, but then randomly my ac87u shit out so i replaced it with my ac68u, and then i started having this problem where some people can connect fine but some have no internet access. like if i connect to an access point with my iphone it will work fine, but if someone uses there iphone it will say no internet connection. this issue sometimes happens for laptops, sometimes internet works fine on an android but wont on an iphone.

so i restarted every single piece of equipment a million times and i have the same issue, some people have internet access and some connect to the wifi fine but get no internet access.


i then took off the ac68u and switched my modem to gateway mode and connected the switch to the modem gateway directly. and im still having the same problem


i jsut dont undeerstand why some people connect fine and some dont. and its not even on one set of access points, its on every single on. like if i connect to access point b for example, it will work fine,and if someone else tries connecting with an android or something to the same access point they wont have internet access.


i assume its either my switch went bad too? or do i just have to full recreate the wifi networks by resetting each access point and then making the network again?


thanks!

Sounds like DHCP pool problems to me, personally. Maybe DNS server too. I hope that the DHCP server is DISABLED on EACH of those APs, and that the MAIN router or gateway, is set to have a DHCP pool set large enough to accommodate all of the wireless client devices that could be connected, and DNS server is valid.

I ran into that troubleshooting a coffee shop that I frequented, they had a router, but only had like 5 DHCP addresses in the pool for customers.

Also, it goes without saying that each of those APs should be connected, with LAN port to upstream LAN port, not WAN to LAN (double-NAT, extra DHCP layers, no bueno - that's "no good" in Spanish, minus the tilde.)

Strange that it just stopped working with a gateway change and that the isp router doesn't work either--except that 'daisy chaining' isn't something you can do in ethernet with access points, so give us some more details about that setup as I suspect an unsupported configuration there that just happened to work with the ac87u.
