Don't get spoiled or spoil the kiddos during a reset period.
Those coming from Gen3 to Gen4/5 will get 20 days of resets. Those coming from Gen4, unless they get a new SAN, will not get daily resets.
Anyways, yeah, Gen5 use the 25MB download package, and the 3 or 4MB upload package if testing that.
As for website issues, yeup, I have experienced odd slowdowns when opening websites, but have only experienced it when Web-Accel is on. I suspect Gen5 is more popular than expected and those servers take a good beating once in awhile thus causing page hangs and other abnormalities.
Gen4 had similar launch issues early on in its life, after a month or two everything was good to go for most everyone till the congestion started to take a toll on it.
By the way, if your able to, when testing, do direct connections...
As far as rebooting the modem, you can do so in the WebGUI under the Advanced Menu, there will be an almost invisible "i" icon near the language selection, click that, and you can click reboot.
