Posted: Tue Mar 14, 2017 1:51 Post subject: Client Bridge on TP-Link WR841N v11
I'm hoping someone can tell me I'm an idiot and I missed a simple step (or I'm using the wrong firmware), because I've been tearing my hair out for a few days on this one.
This is my setup:
Code:
[Internet]
|
[Modem/DHCP]
| 192.168.4.1
|
| (wired)
|
[Access Point] 192.168.4.2
z
z (wifi)
z
[WR841N] 192.168.4.50
|
| (wired)
|
[Test PC] (DHCP static allocation 192.168.4.15)
Client bridge will work for a few seconds, then start dropping packets. I try to ping my modem (192.168.4.1) and I can't even reach that. I get big batches of dropped packets, then it might start working again. I get ICMP HOST UNREACHABLE and ICMP REDIRECTS from the DDWRT unit. If I ping the DDWRT unit (192.168.4.50) I get DUP ICMP replies. If I go into Administration -> Commands and send 'ping 192.168.4.1' it sometimes works, sometimes fails. BUT if I renew my DHCP lease, it will begin working again. Only to stop again.
Pretty much the same results as this poster from 2012. The
I first tried the latest firmware I could find
/betas/2017/03-04-2017-r31571/tplink_tl-wr841ndv11/tl-wr841nd-webflash.bin
Originally I was using a wireless network with WPA2-AES, I have also tried using an unsecured network: same behaviour.
I have tried doing 30/30/30 reset: same behaviour.
In case it was a broken build, I tried r31221: same behaviour.
Since the Repeater Bridge instructions said it required build >= r28493 I thought I'd try that, but the first WR841Nv11 build was r29147: same behaviour.
Before following all these guides I set it up according to instinct, so originally I missed disabling SPI Firewall and changing routing mode from "gateway" to "router". I still had the same behaviour.
My test PC still receives the DHCP offer, that part works ok. I tried overriding my gateway from .1 to .50, that didn't help.
In the DD-WRT config I tried it both with Local DNS set, and not set.
Under Wireless -> Default GW Mode I tried Auto, Manual (.1) and Manual (.2).
Wireless SNR is typically 15-20, but I don't think there is an issue with the actual wireless link, since I can still get DHCP offers when requested. Something just seems to be wrong with the bridging.
I have tried a lot of things. Any more ideas? At this point I'm starting to look at OpenWRT, or perhaps spending more money on a router that supports Wireless Client Bridging out of the box.

Disable firewall and dhcp, change wan to disable.
Openwrt and gargoyle works in the same way. Search on google relayd for info
Thanks for taking the time to look at this mh3g, but I think you missed the word bridge. I'm trying to run a client bridge, not in client mode. So DHCP is already disabled, I won't be able to contact the router if it's on a different subnet, and I've already disabled SPI firewall. Any other ideas?
wr841nd mode client bridge (routed)

Thank you mh3g. I tried your solution of putting the router IP address on a different subnet (I have already tried everything else you suggested), it didn't help. I still only get connection for approximately 20 seconds before it drops out. As before, renewing the DHCP lease restores the connection briefly, then drops out again.
It is also worth pointing out that your 841nd is v9, mine is v11. Different hardware.
I have upgraded to the latest version as of today, 03-21-2017-r31722. Still suffering the same issue.
