I recently bought a TP-Link Archer C2 router, and I am very satisfied with it so far. I have only a single problem: Bonjour service advertising seems to be broken.

My network:

• Simultaneous 2.4 and 5 GHz networks


• 2 Macs, 1 Ubuntu and 1 Windows 7 computer


• 3 iPhones, 2 Android phones


• HP printer


• Kindles, etc.

What I tested:

• The Macs do not see each other in Finder


• My Mac does not see the network printer (used to work)


• My Mac does not see the iPhone, when I start some app which provides WebDAV access and announces it with Bonjour


• Bonjour Browser shows only my local computers advertisements


• The iPhones do not see the AirPrint service of the printer


• I've tested using only a single WiFi band instead of both of them, did not help


• The router provides IP addresses from the same IP domain to all of the networks (192.168.0.1/255.255.255.0)

Where could the problem lie? What do I need to check to fix this? Is it maybe some multicast package forwarding issue? If so, where can I fix it?

Do you have any active devices between your Mac and the router? Bonjour packets have a TTL of 1.

Does running dns-sd -B on your Mac list your other devices? Does dns-sd -F show local as a browsing domain?

Try pinging: ping 224.0.0.251 or ping6 ff02::fb

On the router, try enabling Network > WAN > Advanced > Enable IGMP Proxy and IPv6 WAN > Advanced > Enable MLD Proxy – it shouldn't affect multicast packets on the LAN, but you never know. :)

Try setting Wireless 2.4GHz > Wireless Advanced > DTIM Interval to 1.

Try disabling anything firewall-related (Security > Basic Security > Firewall > Enable SPI Firewall and all the options under Security > Advanced Security), and if this solves the problem, re-enable them one by one.

I've contacted TP-Link's user support. In the result of this, they have improved the Bonjour support of the router in the 11/17/2014 software update:

So far (since 2 days) it seems working fine, so if you have similar problem, you only have to update your router.

I have had a similar issue with the TP-Link Archer C50. Bonjour devices would just not show up.
I had originally set up the router as an access point, basically extending an existing LAN with additional WiFi.

What solved the problem for me was configuring the router as a router, that is, selecting this option:

Before enabling it, you will have to plug in something into the WAN port. Then, after enabling it, unplug the cable, wait for the router to restart. Now connect your PC again, navigate to 192.168.0.1 (the router's default address), and change the Network » LAN address of the router to something other than your existing router's IP. Restart, then go to DHCP and disable the built-in server. Restart once more and the router should work.
