68R hangs DSL modem

[vrapp]

I have NT66U and AC68R, and AT&T DSL service using Speedstream 5100. While NT66U gives no problems, AC68R occasionally hangs DSL modem. I.e. at some point the modem hangs, and if I connect the computer directly to the modem, modem's UI does not respond. Powercycling the modem fixes it, until the next time.

I even tried another modem, Speedstream 4100, and soon it hung as well.

Naturally, the first thought is to blame the modem, but this never happens with NT66U, so it looks like 68R is doing something that NT66U does not, and that modem does not like.

Looking for any input about what it might be. I'd prefer 68R, mostly because of USB3 plus trendmicro protection.

Are you using the modem as a PPPoE bridge with your Asus acting as a router?

or

are you using the modem as your router and the Asus devices as APs?

I suspect you have multiple devices acting as a router, which would probably cause problem. Only 1 router is needed. I used my RT-N66U with my Speedstream 4100/4200 (in bridge mode) with no problems.

The modem is in the mode "PPP is on the computer", the router has "WAN Connection Type" = PPPoE. Same mode as yours, as I understand. No other routers.

With N66U I have no problems either. They are with AC68R.

The 4100/4200 has a full bridge mode that disables everything but the PPPoE functionality (meaning no GUI access and you must reset the device to get it out of the mode). Maybe try that?

You have to surf to the modem's GUI page and go to brgmode.htm or brgmode.html and click the button. I run my speedstrean in this mode.

Tried .htm, html, and .cgi - no special page, all 3 redirect to its homepage. According to google, it looks like it's for 4200. Is yours 4100 or 4200?

Seems like you are right. Though, I think you can still achieve the same "PPPoE only" mode: https://www.dslreports.com/forum/r17049953-SpeedStream-4100-Bridged-mode-vs-PPP-on-the-computer


Whether this full bridge mode will solve your problems, I dunno... I could be very wrong.

PS - Thanks for including the verbatim "PPP on the computer" mode you are using because it made Googling your problem very easy.

Got it. Switched to the "bridged mode", which by the way has the following description:

Bridged Mode (PPPoE is not used). This mode must be used if you are connecting to a non-PPPoE network. Selecting this mode will cause the modem to automatically restart.

Still have web UI through the router like before. Will see if the problem is solved.

update: the problem was not solved, soon dsl modem hung again.

But then I managed to fix it by changing wireless network card to another model on one workstation - I did have a feeling that the modem hanging was correlated with the activity on that computer. After that, not once.
