Fixing stuff and maybe other things.

Configure TP-LINK Archer C9 (or C7, C8) for access point mode

Some call it “bridge” mode. The point is you want your TP-LINK to play nice with another router from which your internet actually flows. Like if you have a fiber/DSL/psychic router you can’t replace because ISP reasons but you want some wifi that doesn’t totally suck. For example.

The reason this can be confusing with the Archer series is that many other routers have a setting like “AP mode” that you turn on and you’re done. Or Their WAN (a.k.a “internet”) port can be used for this job. While it’s a nice piece of router, the Archer doesn’t make it clear how to do this. And you may be dealing with/swearing at messages like “WAN and LAN cannot be on the same subnet”.

Anyway, let’s kick this pig! (Translated: “Let’s do this.”) I’ll just start from the top. You can skip ahead if you’ve already done any/some of these.

1. Don’t connect it to your main router yet

Just plug it in and hit the On switch.

2. Log on to that mess

Connect your computer to it with an Ethernet cable, OR hop on one of its default SSIDs it will start broadcasting automagically. (TP-LINK-XXXX).

With that done, head on over to The default login is “admin” for both username and password. Change that later. Do it.

3. Completely ignore the rest of the quick installation guide

Toss that thing. Or save it for later. Whichever.

4. Set a static IP address

We need your TP-LINK to have a different IP than your internets-providing router, which may likely also be using We don’t want them arguing with each other. This can be whatever you want, so long as it doesn’t conflict with anything else on your network. I usually go with

Visual guide for what to do here.

Ignore “WAN” completely.

5. Disable DHCP

Your other router will be on DHCP duty, so the TP-LINK shouldn’t bother.


6. Other stuff

Change the SSID names and turn on WPA2 security. And change the router login (under Settings > Password and not under Security like you’re very reasonably assuming).

7. Hook it up

Plug the Archer in to your main router, Ethernet-cable-style. Do NOT use the TP-LINK’s WAN port. Use any of the other four.

8. Dance

Because you’re done now.

Thanks so much!

Thank you! If only I had read this an hour ago…there would have been much less yelling.

I do this and it works as an access point, but I cannot back into it with the new IP address. I have to disconnect the router from the rest of the network and plug it directly into my laptop Ethernet port and do a hard reset and start over.

I can re-input the settings above, reboot, retest, etc and have access to the Archer. As soon as I plug it into the rest of the network (not using the WAN port), I can no longer access the Archer at the new static IP address. Even unplugging it from the network will not let me back in.

Not sure how to determine if I have a bad router.

Any ideas?

#5 by Frank on 01.27.16 at 3:29 am

Mark, the same problem here. So i do not think its a bad router. Also the tether-app isn’t working anymore. Here are my findings:

Wifi works great no problem.
Wired devices have no internet.
Tehter-app not working.
device can actually be connected through the new static ip-adres.

So it is only a solution as a wifi acces point.

I wanna dance but do not have a reason write now 🙂

Is there a solution on how to make it a kind of extender for my excisting router provided by my isp, for the use for wired and wifi?

Sorry for the bad english, i’m dutch and trying 🙂

#6 by mind on 02.17.16 at 8:27 pm

hey mark.

i had the same problem, but just because i did a small mistake.

i used the same static IP which is shown in this how-to, not realising, that my router uses: instead of
just a hard reset (button on the backside of the archer!) set back all to factory-settings and i had to reconfigure my c7.
so maybe ur ip-range of your other router is not the same as shown here.

sorry for that bad english 😉

When I disable DHCP-Server I can no longer access internet through WiFi. Disables ability to connect to it. I can see my networks name on both my iPhone and my laptop but cannot log on to it.

+1 #3 Dave. Much less yelling if I’d have read this first….

#9 by Stan on 06.11.16 at 9:28 pm

Thank you, very straightforward and simple. Do you have further instructions for using a 2nd router as a range extender when you cannot connect to the base router via ethernet cable? I want to put the 2nd router at the edge of the first router’s “good” range to extend the reach. I can’t run an ethernet cable to my 2nd router (the C9).

#10 by Ahmed on 06.16.16 at 2:58 pm

I have a C7 and I cannot get to see the Advanced setup tab shown in your example.

#11 by laurent on 07.07.16 at 11:17 am

Yep, but how to make Archer C9 as a repeater coming from my BB hotspot, meaning no connection between smartphone and C9V1 ? Thanks

#12 by John on 07.15.16 at 8:34 am

Followed the instructions and while my network connections worked, my internet connection for wired was down. Reset router, tried again, same thing. Reset router again and tried again… same thing. FINALLY I TURNED THE POWER SWITCH OFF, left off for 10 sec. and turned back on. EVERYTHING NOW WORKS!!!

#13 by Lucas on 07.15.16 at 7:04 pm

Has anyone been able to use this as a wifi repeater? I have a Archer C3150 (similar interface to this), and want to connect this router *via wifi* to a Verizon Jetpack, so it will blast the hostpot signal everywhere. Wifi repeater/range extender should be out of the box for something I paid almost $250 for….. Any help would be much appreciated!

#14 by Bruce on 07.18.16 at 9:02 am

Thank you. This is wonderful information that was much easier to follow than what I was trying to read and follow on the TP-Link website. My Archer C7 modem is now functioning in bridge mode just as I wanted to.

#15 by Reino Elgaard on 07.26.16 at 7:48 am

what aboutthe SSID.

should it be the same as the router (have 3 tp-link archer c7)
Only 1 should be used as a repeater.
the last one is at another apartment (same building and same internet)

hope i`ll get an answer 🙂

#16 by Lode Mandervelt on 08.10.16 at 3:08 pm

works like a charm…except I can’t reach the admin page of the router any more… any ideas ??

#17 by Guilherme on 08.11.16 at 2:27 pm

Worked like a charm, thanks a lot!!

I have two Wifi routers connected to a wired router that is connected to my cable modem. Wifi Router #1 is one I’ve had forever and works fine. Wifi Router #2 is a new TP-Link Archer C3150 that I’m trying to add into my existing network (to replace an older one that finally gave up).

On Router #1 (which works just fine) and on my original Router #2 (that gave up), the connection from wired router to router #1 is via LAN port, to be part of the same network as my wired router. It’s configured with a static IP. But I also have to explicitly configure it to point to the wired router as the Gateway and DNS server.

The instructions above don’t explain how to do this. In fact they DON’T do this. So how can my router #2 (the TP-Link Archer 3150) know how to talk to the internet via the wired router? It NEEDS a Gateway and a DNS server definition. I don’t see any means to configure these on my Archer C3150’s LAN settings. Dang.

#19 by Greg on 09.27.16 at 9:59 am

Well I got it working as an Access Point. The instructions above DO work. There’s surprisingly no real NEED (as on my other routers) to explicitly configure the Gateway or DNS. It just “works”. BTW, these same basic instructions for Access Point mode are provided by TP-Link at . After things are rebooted (both the wired and wireless routers), it works. Almost…

I still have one weird problem. If I plug in my laptop’s ethernet connection to an Archer C3150 LAN port, then run “ipconfig /all” in a command window on my laptop, it shows TWO gateways configured: and The 1.2 one is the Archer C3150. The 1.1 is for my wired router — and it is the ONLY one that I really want. With the 1.2 one coming first in the Gateway ordering, it simply does not work! I cannot use my laptop to open the Archer’s admin console at even though I’m connected directly to it! Frustrating.

But if I connect my laptop via one of the Archer’s wifi points (2.4G or 5G), then the “ipoconfig /all” shows only the wanted 1.1 Gateway — and everything works fine. I can connect to the Archer admin console, and everything else too.

Also, I’m using two of the remaining 3 LAN ports on the back of the Archer for my Yamaha receiver connection, and for one of my NAS connections. And they properly see only the gateway, and work perfectly fine. It’s strange that only my laptop (running Win7) is getting the gateway when directly connected.

Well, I can live with this. Unfortunately it means that whenever I have to do a firmware upgrade on the Archer, I’ll have to do it wirelessly. But I did one just now (to bring it right up to date) and it worked fine.

Oh, one final thing. When I configured my NTP server on my Archer, I found that I had to explicitly create a static route for it. I’m using Actually, using its IP address ( Without a static route, the “GET GMT” button fails. Adding a static route (for, subnet, gateway gets it working. This shows that the router itself doesn’t really know how to get “out to the internet” through the wired router. But other devices connecting THROUGH the router somehow get the proper gateway of assigned — without requiring an explicit gateway setup on the router’s LAN.

(I absolutely DID have to define the LAN static route on my other modems, that are running DD-WRT. The Archer somehow figures this out itself.)

OK, that was a very long-winded comment. We now return you to your regular programming….

#20 by Dan K on 10.02.16 at 7:07 pm

Thanks for the tip! I was able to stumble into this after a few hours of experimenting. Everything is working now, except I am no longer able to access the Archer’s Admin screen. It’s simply inaccessible via wireless or wired. Any idea why that’s happening?

#21 by Matt on 10.06.16 at 4:14 pm

Thanks! These are the steps I’m accustom to, but really helpful to quickly find where all the settings are at.

So glad it lets you set your own subnet when setting the static IP. Some routers don’t let you do that, which fucks everything up on my non-standard subnet network.
