I'm using currently old Sagemcom router. I'm searching for sorting better with FTP, Wi-Fi 2.4GHz + 5GHz (Dual WLAN) and VPN server (something more secure than PPTP). I have narrow the search to two models: ASUS DSL-AC52U and DSL-AC68U.
1) VDSL2 performance
DSL-AC52U: VDSL2 Upstream: 150Mbps, Downstream: 200Mbps
DSL-AC68U: VDSL2/VDSL/ADSL2+/ADSL2/ADSL Up to 100Mbps/100Mbps upstream/downstream
I suspect that the better VDSL2 performance of DSL-AC52U comes from implementation of:
ITU-T G.998.4 (G.inp) Improved impulse noise protection
explained here (120 pages pdf): https://www.itu.int/rec/T-REC-G.998.4-201501-I/en
I cannot find information if this standard only push maximum limit of VDSL2 performance or whether it will help improve speed in case of bad cables (my current router provides only 25Mb/s)
On other hand DSL-AC68U has dedicated chip: 8MB Flash/64MB DDR2 RAM for xDSL/Modem.
-> if someone had chance to compare two in VDSL2 performance I would be grateful for comparison
2) CPU+RAM
DSL-AC52U: 750MHz + 128MB RAM
DSL-AC68U: 800MHz or 1 GHz + 256 RAM
Which rev of DSL-AC68U had better CPU?
Does slower processor and smaller RAM will impact performance of DSL-AC52U (using FTP and VPN server)?
3) USB HDD
DSL-AC68U: manufacturer hardware doesn't support sin-down for attached HDD
Does DSL-AC52U behave the same?
