Our company has three of these swicthes: T1600G-28TS 2.0 (aka TL-SG2424), Hardware Verson 2.0
(Emphasizing the HW version as it appears to be quite important in this case.)
Nowadays modern browsers refuse to connect to the Admin UI via HTTPS:
Also, accessing any of the switches via ssh also fails:
user@host:~$ ssh firstname.lastname@example.org
Unable to negotiate with 10.11.12.13 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1
The product page is here: https://www.tp-link.com/us/business-networking/smart-switch/t1600g-28ts/
The Support page is here: https://www.tp-link.com/us/support/download/t1600g-28ts/
Please note that for HW V2 there is nothing on the main page, as if it never existed, and the support page does have an option for V2, but it seems as no any firmware upgrade has ever been released for V2.
Telnet and HTTP are not acceptable options for us to communicate to these swicthes.
- Does anyone know why has T1600/TL-2424 V2 been abandoned? What was wrong with it? IT works just fine (except for the aged firmweare)!
- Is there any chance to get updated firmware for these swicthes?
- Any chance for V3 firmware to be adapted to work for V2?
Thanks for any hints! Your help is highly appreciated.
