The telnet option doesn't display in the debug form for me, and even if I try and force it, either by using the browser dev tools and forcing the css to show the form block, or manually issuing the form post with the correct parameters using a curl request, the option doesn't stick on the debug page and the router doesn't respond when I try to telnet (port 23) to it.
I am on current firmware V3.2.15.25_1.3.15 and telnet has been enabled by default on my router and sats.
Maybe it has something to do with my account being enrolled for betatesting? Maybe some other betatesters can answere this?

Telnet stoped working after I did a factory reset. But got it up again using this utlity

I believe telnet was removed in some recent FW updates. Even for beta testers. :smileyfrustrated:
Glad the work around helps.
- arlomikeJul 30, 2020ApprenticeI too have experienced DNS timeouts...not frequent but enough to notice its a resolver issue. The routers recursive server is buggy. Wonder if I can telnet in and install powerdns recursive instead. It sucks that the we can't set what DNS servers DHCP hands out. I'm not about to manually set DNS servers on all my devices.

What version of FW do you have loaded?
I'm using v32 and have no seen any DNS issues thus far. Using Auto DNS detect on the RBR which sees my ISP DNS.
You might try setting manual DNS addresses to something else like 1.1.1.1 and 9.9.9.9 on the RBR to see if this maybe a ISP DNS issue. Not th first time ISP DNS has causes problems.

How do you disable it after enabling it? I notice that it's available outside network (WAN).

I guess you could set the
telnetd_enable=1 to 0 and do a nvram commit and reboot
