Region : UnitedKingdom

Model : TD-W8980

Hardware Version : V1

Firmware Version : Out of box

ISP : PlusNet


Recently bought a TD-W8980 and whilst all appears ok, tehre's one glaring issue which is making it pretty much useless, any device on wifi cann't see or communicate with the wired lan devices. both wifi and lan can browse the internet fine, and port forwarding works nicely for ssh and rdc protocols but internally it's just not playing ball and I cannot see any option that could possibly have an effect.

Has anyone else had this and is there a known fix?

HI, thanks for the reply..

Client Isolation is unchecked so not that.

Anything else to check?

Some firewall application on computers can block network communication. Can you ping other computers?

It's definately the router at fault, if I reconnect my old BT home hub everything is fine...

One of the wifi devices is my iPhone and one of the wired devices is a SkyHD pvr so firewall software doesn't apply.

I have W8970 and I can't see any troubles in network communication. Wired and wireless interface must working in bridge. Please report this trouble here - http://ticket.tp-link.com/index.php?/Tickets/Submit - maybe this is some problem in firmware with apple OS. I can't check it because I don't have this model.

I have the exact same problem, and I don't know what to do. All i know is, if you disable the firewall, then the wireless machines are able to communicate once again with ethernet plugged in machines. It would seem like the router is treating devices on the wireless differently. However, disabling the firewall isn't a solution and we are back to square one.

Just to update the thread, I did in the end resolve this by redoing the initial setup, why it made a difference I don't know as I used all the same settings..

However the wireless range is utter carp and some of the speeds I'm getting are quite simply disgusting..

The USB storage/printing services are great but those aside this really is the biggest waste of £60 I could ever have done..

Update Firewall to fix
2018-01-22 20:20:08
Old thread but I finally found a fix.

Enable the firewall, set specific rules to deny any traffic you don't want then change the default filtering rules to allow any traffic not caught by the defined rules.

Update Firewall to fix

@danip  Hi. Just seen your post. I have exactly the same issue with a W9970 router. Wifi connected clients (connected to router wifi) cannot see/access clients on the ethernet network (I use TP Link powerline adaptors). Looks like the firewall is different on this router and I need to add specific LAN/WAN host?  I'm not familiar with firewalls I'm afraid. Can you help?
