TP-Link TD-W8968 telnet - Authorization failed after trying 5 times!!!

Model : TD-W8968
Hardware Version : TD-W8968 V4 0x00000001
Firmware Version : 1.0.5 Build 150504 Rel.57027
ISP :
I can only log into the TD-W8968 via telnet five times (using the correct login and password), after that it gives me the error "Authorization failed after trying 5 times!!!" and I have to either reset the modem or wait 10 minutes for the login to reset.
I assume this is supposed to lock out after 5 INCORRECT logins to deter malicious attempts, but it is also happening when the login and password are correct. Is there a fix or update available to correct this error?
Here's a log of the 5th and 6th login attempts:
# telnet 192.168.1.1
Trying 192.168.1.1...
Connected to 192.168.1.1.

I think you should log in the management IP, set up all figures and reset it again. If it still not works, you should contact supporter for help.
Done all that, and updated the firmware as well. If you read the post above yours, I quoted the statement from TP-Link support basically admintting it is broken by design.
As a last ditch effort I also tried code I used to use before using telnet - grab the HTML from the modem status pages and extract the relevant data that way. That used to work (and still does) on the TP-Link TD-W8960N, but not on this one. The TD-W8968 now generates it's web page stats using javascript which doesn't work with my code. I'm not really complaining about this though as it's probably much more efficient and secure.
So, it's the end of the line with the TD-W8968 as far as I am concerned. a D-Link DSL-2790U will replace it tomorrow and the TP-Link will go in the cupboard as an emergency spare.

Mine is a Small Home Office, but I guess I'm not a 'normal' user :-)
Telnet is a very useful and well known feature, common to most SOHO modems with Broadcom chips. It's also
the main reason I stayed with TP-Link and bought the W8968 to replace my trusted but aging W8960N (which
recently survived a lightning strike that took out my ADSL port).
Although I wrote my own software to use the telnet interface, I'm certainly not the only one using it. There's other
software like this DSLstats http://www.s446074245.websitehome.co.uk/index.html using telnet as well.
I'm pretty sure you'd agree that no-one expects useful features to be removed when they buy a newer device?
I doubt that TP-Link will make any changes to their firmware just because I'm not happy, and they probably won't
notice that I won't be buying any more of their modems unless this is fixed. I've already bought a replacement in
case it isn't - a D-Link DSL2970U, also a SOHO device but it isn't crippled like the W8968.
I like your good idear!
