It appears that G.992.5 (a.k.a ADSL2+) is only supported by the ZXDSL831BII. That would explain why you are not getting the maximum speed for your line.musicalfruit wrote:What kind of speeds does the D-Link DSL-520B support?
I had a ZTE ZXDSL 831II that was kinda flaky so I had purchased a ZXDSL 831B as a backup modem from eBay.
It works but after some speed tests, it seems that it's capped at ~5Mbit. Usable but not that great since my line is normally around 11-12Mbit.
Thanks!
The D-Link DSL-520B supports G.992.5 and hence should get you the speeds you used to see on your line.
