Yeah the ZyXEL AAJZ.14 with just jumbo frames, by you [original adsl_phy.bin] is doing alright for this hour.
Before I changed firmware I did "adsl connection --down" & after uploading let it restart into a sync. Maybe due to not waiting [the line fit the mold of x1 after 3 weeks, and took a few hours for v to stabilize. plausible].
Edit: First time this happend, the modem rebooted itself; but the jumbo-frame FW I've used before was of Olipro. I'm going to flash to Olipro's. That is, assuming it's not my configuration file made for jumbo+3925 that I also use on the jumbo-only. I rule out electricity because it didn't come on and off, rather a lengthy reboot. To clarify, I used re-opened DSLStats a lot today so it might be this modem, too, has reboot issues. But I'm doing this to verify. Other than that v is running just fine, need more time & another switch back to x1 to know if it's better or worse. Right now things are better but time is needed to draw relations.
Edit2: Towards the end of the tones v has a better looking SNR graph than x1, but up until mid tones x1 is better. Also, notice the drop with v in multiple spots at tone 800. So, I rather not evaluate which is better. I plan switching to x1 again to confirm.
Edit3: I think I'll leave it on v, for some reason there are fewer errors & unless there is an increase I'll remain on it. Before that v didn't do as good as now [as good as x1 did], and x1 also did better than v in the first week after switching to it, before gradually getting worse. Absolutely no idea why it's like this. But when x1 worked well, like in its first week or two, it did better than the prime of v. I'll use v for another couple of days, and decide if to try x1 again.
