Anyone able to bridge two routers at full 1.3Gbps speed? Max I get is 702M, even if the routers are in the same room, a few feet away from each other.

I set it up with AC/N-Mixed, ch.36, VHT80, lower/lower, beamforming enabled.

I got a bad flash on my WZR-D1800H. I tried using PumkinTFTP, and when pressing the AOSS button it triggers Pumpkin and ask for “firmware.ram”. I tried the latest firmware from DD-WRT & from Buffalo’s website; renamed them to “firmware.ram”. It won’t take it.

I don’t have a serial adapter. Guess my question is, if it really wroth getting a serial adapter kit? if so which one? Is there another alternative way to de-brick? Or am I better off now just trash this thing?

Anyone using QoS?

Once I turn it on (to help with an Obihai adapter for VOIP, which works great, voice quality is great), my overall bandwidth is cut but about half on the download side.

I set the QoS downlink to 0, uplink to 12000 (my actual upload is ~14mbps).

I only do MAC priority.

No one else having random disconnects from wifi?

I've never had this issue before, it all started when I updated to latest builds, prior to that I had a build from December 2014.

I have phones, tablets, and laptop disconnect randomly from the wifi. After about 30 seconds or so they reconnect.

WIFI is broken in the last 3 commits on the Broadcom SoC. Might be fixed with TODAY's commit

Thanks for the info mb! I'll try 28054 and see if that fixes the issue. It's horrible having these disconnections all the time, I'm working from home on the company's VPN, and it's messing up the apps I'm using.

I'm running 2 D1800H's in repeater bridge mode on wl0, router1 has wl1 disabled, router 2 has wl1 serving the house on 2.4GHz N-Only.

I flashed 28054 on the 2nd router (which serves all clients).

Constant random disconnects in the past few days.

No idea how to begin troubleshooting this...

Can someone recommend a build that has solid wireless performance as well as repeater bridge working?

Thanks!

What tx power settings are you guys using on wl0 and wl1?

If I set mine above 100mw, the radio is unstable.

I read that the stock is considered at 1000mw in dd-wrt terms, is that true?

I leave Tx Power at 71 which, for DD-WRT, means "Auto." The router handles it.

Did anyone notice how some builds are ~23mb while others are ~25/26mb?

What would be the difference?

How the current build of dd-wrt on the d1800h? Is wifi working currently? Is the lamp wifi working, e.g. does it blink when data is being transfered? For the last many build the lamp is just on all the time on my unit with dd-wrt. Is was working correctly on these builds

Mine is on all the time, but that's prolly cause I have the two routers in repeater bridge mode on wl0.

I do see a flicker on occasion, and the wlan light is red, unlike the stock which was blue if i recall.

Kong no longer produces separate builds, just get the latest off the main FTP.

ftp://ftp.dd-wrt.com/betas/2016/01-25-2016-r28942/buffalo_wzr-d1800h

is latest as of right now.

What are you guys running these days?

Still trying to figure out a stable build that doesn't break repeater bridge or QoS.

I'm currently trying r29048 but wireless on the repeater stops working, wl0 loses connection to router #1, and can't connect to wl1 N/G mixed 2.4GHz.

I'm also experiencing random disconnections on wireless clients, various different hardware (Dell, Thinkpad), all have Intel cards, as well as various cellphones, HTC and Samsung.

Wired to repeater rounter (#2), I'm getting 30MB/s transfers.

How do you guys back up settings before flashing new builds? It's such a hassle configuring from scratch every time (2 routers, QoS, port forward, openvpn, etc...).
