Some owners of TP-Link 1043, me too, have trouble with same things like region regulatory for example. Brainslayer wrote to 1-st of us, that it happens because flashing wrong image of Buffalo to TP-Link routers. May be in the the TP-Link directory of FTP is wrong image? I don't know...

OK, I'm wrong. I saw the Buffalo images - all about 17-18 MB. The TP-Link image less than 8 MB. I don't know why Brainslayer wrote about flashing wrong image to TP-Link...

You should read the forum. Your version is so outdated and not relevant for present time. But you can still waiting. Wink

Maybe his version is outdate but the problem still with the latest version Rolling Eyes


After flashing with that image I have no wifi issues. I suggest you try it and see for yourself.

I'm really satisfied now now that my wr1043n router works finally!

UPDATE:

It still doesn't work Sad

I'm testing firmware from this blog post:
http://darranboyd.wordpress.com/2013/03/11/tp-link-wr1043nd-dd-wrt-build-14896-memory-leak/#comment-240

This is what I did:
1. download backup off all settings.
2. downloaded factory-to-ddwrt image
3. flashed image with erasing all previous settings
4. reloaded settings from backup

Now I wait...


Works great for over 4 days, no wifi issues!
Before I would get wifi issues after 12-24 hours...

UPDATE:

It failed this evening on 6th day after first 5 days working ok...

I connect to router via ssh as root user and when I tryp "dmesg" I see these log messages:

<3>[542878.060000] ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 DMADBG_7=0x000286c0
<3>[542878.080000] ath: phy0: Could not stop RX, we could be confusing the DMA engine when we start RX up

This is bugreport for this issue:
http://www.dd-wrt.com/dd-wrtv2/bugtracker/view.php?id=4388

Please help developers with your logs and any additional info, because the more info they have faster this issue can be resolved.

Also if anybody can donate one router to the ddwrt project that would probably speed things up considerably...

Just saw same issue in dmesg log as in openwrt bug, this is from my wr1043nd running ddwrt:

<3>[542878.060000] ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 DMADBG_7=0x000286c0
<3>[542878.080000] ath: phy0: Could not stop RX, we could be confusing the DMA engine when we start RX up

Check out openwrt bug, this looks to be the same issue:
https://dev.openwrt.org/ticket/9654

It looks like there is a solution in openwrt bugtracker, but I haven't tried it yet:

Has anybody tried this "german firmware" workaround? [1]

Here is what this guy has done:

"What worked for me is get it back to TP-Link Factory, flash the German FW, then flash BrainSlayers v24-sp2 (12/31/12) build 20453. There is both a factory to DD-WRT and a ‘final’ DD-WRT version. Go here: http://www.dd-wrt.com/site/support/other-downloads
and find them here: Downloads › others › eko › BrainSlayer-V24-preSP2 › 2013 › 01-01-2013-r20453 › tplink_tl-wr1043nd"

This sound like the workaround for WAN bug, nothing about WLAN..

I've had this router since 2010. Ver 1.6

Ran great for the first couple of years.

ABSOLUTELY NO PROBLEMS.

I tried to upgrade to 21xxx, and it was a faulty install with the 192.168.11.1 error.

So I reverted back to 14896. I'll try for a newer 149xx build that someone sent me. Is there a mini or micro version of this?

I got the bright idea to try a new power source. They do wear out I think and maybe they lead a more rough life than the router itself.

I'm scrounging around for a spare power source.

Also I'm going to try to see if playing around with the TX/RX antenna chains will do anything. I'm going to experiment with tx=1 and rx-1+2+3

Take the last version for your 1043. It seems like usage wrong version of FW. The address after burning should be 192.168.1.1 Images with this error (bad address) was fixed I think.

I found a possible fix.

I changed the TX and RX antennas from stock (can't remember, but it might have been 1+3 and 1+2+3)

To 1+3 and 1+2.

I've been stable for a day so far now.

Could others test and let me know your results?

I'm still getting this with (I believe) the latest version.

For a bit of background, I'm replacing a BT Infinity Homehub (brand new) because I do quite a lot of poking around on Linux, so I often grab ISOs down via legal torrents using Transmission. I noticed that unless I reduced the number of total peers to 250, and restricted my torrent download speed to about 1Mbs (which isn't ideal, esp not with Infinity), the HH would often hang up with these symptoms - the WLAN SSID would be visible, but you couldn't connect to it until you power-cycled the HH.

I got the 1043, brand new, last night, 30-30-30ed it and put DD-WRT v24-sp2 (07/24/13) std - build 22118 on it - this is the latest build, isn't it, and isn't a testing build? While it has been more stable than the HH, I found that when I opened up the torrent limits to 1000 then down to 500 peers, it was still hanging, though not so readily as the HH. Going back to 250 peers I found I could leave the torrent client bandwidth unlimited and it mostly was ok, though it has still failed a couple of times, once on fairly low download speed/number of peers (my test torrents were almost done).
I've tried the above fix with the antenna settings (TX-1+3, RX-1+2) and I'll see how I get one and report back. For anyone trying to test this, finding a few (5-10) well seeded legal torrents (open source software ISOs are ideal) is a good way of hammering it.
Cheers - MH
