How do you connect 3rd party wireless router and have it function as AP

jang430
I have UTM 9.3, and I am using TP-link wireless router. How do I configure the wireless router to act as AP only? As of the moment, I did all steps below, but haven't got internet. Steps I've done: Assign router to 192.168.5.2 IP address, DHCP server enabled (so it assigns IP) and set wireless security Assign eth2 (named it wifi) as ethernet port 192.168.5.1 Plugged WAN port of AP to eth2 of Sophos UTM ASG110 Create Firewall Rule: wifi (Network) Service: Websurfing Destination: Any - to allow surfing Created new masquerading Rule wifi (Network) to External (Wan) I did all these steps, with no internet.

    When you say "DHCP server enabled", do you mean you have DHCP enabled on the router you wish to use as your AP? If so, and you also have DHCP enabled at your UTM then this may be your issue. Turn off DHCP at the router and only use DHCP at your UTM otherwise you'll end-up in a double-NAT situation.

    This FAQ may help...

    Yes, I have both DHCP enabled, at Firewall, and router (AP). Will this be an issue if I've connected the connection to the WAN port of the router (AP)? Not connected to the LAN port.

    If you enable DHCP on your router, your router will try to assign IP addresses to wireless devices instead of having your UTM assign IP addresses. You want to disable DHCP on your router.

    Hello NashBrydges,

    I used to have the setup you mentioned before. I noticed surfing is spotty, some pages won't load. It seems something is conflicting. I changed the router(AP) to 192.168.5.1, and plugged it's WAN port to my switch. I noticed surfing was free and easy. Every web page would load quickly. The only reason I'm changing settings now is as of this moment, wireless devices connecting to 192.168.5.1 (dhcp enabled) can't ping the wired network devices, in 192.168.1.x IP. So I moved the router(AP) to the back of the Sophos UTM. That's when problem started.

    Hello BAlfson,

    Initially, I'm already using the guide that is setup to the same network. I have 2 APs, both following the guide you've shown. 1 is using 192.168.1.2 as IP, the other is using 192.168.1.3.

    I noticed that while surfing using laptop, I don't have any issues when connected to either consumer APs. But when Cellphones, tablets are connecting to the APs, Android, IOS, both experience page not found, and have to be reloaded several times before the page actually appears. Loading of page is also slow. That's when I decided to move it to another network, naming it 192.168.5.1, and connecting it to the switch within my network. IOS and Android devices surf quickly, without any hitch. Only problem is, it cannot see printers, scanners in my original network, 192.168.1.x.

    I would pretty much like them to be on the same network, with same series of IPs, but I don't know why I need to reload several times. I followed the instructions to the letter. Could it be the 2 APs are conflicting with each other? Is it a DNS issue? But why doesn't laptop encounter the same problem?
