Router 857 ADSL performance ALICE

I have a performance problem with 2 router (model 857) with a ADSL line (Provider IT-TELECOM - Alice FLAT).

If i change router with a home one (netgear, dlink, etc..) my line goes good (at least 4MBit with speedtest.net), if I use one of my cisco it slows down to 1.5MBit.

Configuration works normally without error but slow.

Re: Router 857 ADSL performance ALICE

That's a bit strange since you have high attenuation.

Anyway, try a FW upgrade from:

Re: Router 857 ADSL performance ALICE

I downloaded 2 firmwares. Just a question: the last one (4.10.9) is usable for 857 routers? In the .doc file seem to be only for 836. I downloaded also 3.0.33.

Thank you in advance.

Please try 3.0.33 first.

There are also newer versions, but need a paid support contract to access.

Alos post full router config minus passwords.

Re: Router 857 ADSL performance ALICE

Sorry for the delay but only today i could try it.

I update the alcatel firmware but the result is the same.

I attach my configuration (without passwords)

Bye.
