Hello
I have a strange problem with TP-LINK WR741ND V1.
On BrainSlayer-V24-preSP2 (r24461), lan connectivity between computers on eth ports does not work.
Communication between eth(lan) - wifi(lan) works.
Communication between eth(lan) - wan(internet) works.
Communication between wifi(lan) - wan(internet) works.
Does not work connectivity between eth(lan) - eth(lan).
The total lack of traffic, lack of routing between eth(lan) - eth(lan), does not pass even a single package, as if a switch has stopped working.
The only version that works properly is r21061.
Version r21061 works normally, r24461 version does not work properly.
I've got TP-LINK WR741ND V1 too and I'm having the same issue on r24461. I guess we will have to wait for another version.
So I decided to get back to r21061 in meanwhile, but I wasn't sucesfull. I tried "update" to r21061, I tried to revert to stock, I tried updating stock, I even tried updating to openwrt (not that I hoped that any of it would work, except the first one).

Can someone help me? Point me in right direction?
Thanks.
What symptoms?
When I was using version r24461 always getting error "Upgrade failed."
The way to upload to an older version. Trying to upload to one of these versions:
r23720
r23919
r23082
r21286
r20548
r20453
r24160
Typically, one of them will work if I have r24461.
Then, when you manage to upload one of these versions, you can use r21061 or "tl-wr741nd_v1_v2-webrevert" and if you want you can upload Gargoyle 1.6.1

Thanks for the reply, but I wasn't successfull, with any of these versions. "Upgrade failed" with almost all of them, except few, which even said Upgrade uscesfull, but after restarting I found out, that I'm still on 24461.

Try a few times this same versions.
And if you still do not succeed it can try this solution:
1 On DD-WRT:
1.1 Under Services, Secure Shell, SSHd: check enable, then click Apply Settings button;
1.2 Under Administration, Remote Access, SSH Management: check enable, then click Apply Settings button;
2 Download and install WinSCP (http://winscp.net);
5 On WinSCP:
5.1 Select New Site;
5.2 File protocol: SCP;
5.3 Hostname: 192.168.1.1 (or your router IP);
5.4 Username: root
5.5 Password: your admin pass
5.6 Drag downloaded firmware from Download folder and drop in /tmp
5.7 (Important, I think...) On Transfer Settings, select Binary
5.8 Transfer;
6 On putty;
6.1 Login on 192.168.1.1 (user root and pass);
6.2 Type:
cd /tmp (Enter)
mtd -r write xxxxx.bin linux (Enter) (Sure, replace xxxx with your firmware filename...)
7 Use at your own risk. (I cannot confirm if it will work on your model, router, etc.)
If you succeed then you can upload the factory-to-ddwrt.bin

Thanks, this time it worked. I had a little problem with connecting via winscp, but otherwise I was able to upload and update to stock firmware.
