I have a new SG250-18 as my new lab core switch. All is well but one port for my access point. Single flat /24 (172.16.30.x) and all is well. This switch has a 2 port LAG over to it's 8 port counter part (SG200-8) to get to the my network edge device and to the Internet. So to illustrate SG200-18 _____2 port LAG____SG250-8____Netgear wireless router___Internet.
Everything attached to either switch is fine except I got a TP Link access point (TL-901ND) for my lab to support 3 wireless clients and when I boot it up, configure with an IP address in the current network, the wireless clients can't get to the Internet. To troubleshoot, I have;
1. disabled\re-enabled STP
2. disabled\re-enabled flow control on the port (giga8) the AP is plugged into
3. Configured a 2nd VLAN, put that port in that new VLAN 2, re-addressed the AP but still can't get out.
4. If I plug in the AP into the netgear router, all is well when I bypass the switch
Glad to post my very simple config, to further illustrate but what I am missing on this access point port config?
