I've used the Billion 8800NXL and Zyxel VMG1312-B10A and they are much of a muchness in terms of poor WiFi. They share the same broadcomm chipset, so suffer from the same erratic latency on WiFi. Given that they're both suffering from the same iffy WiFi coverage (poor signal strength and erratic and high latency when pinging the gateway), the remaining items are a) quality of modem and b) feature set.
The Billion, in my opinion, wins.
- The Billion interface isn't as feature rich as the Zyxel, but it works. Zyxel has some bugs.
- Both will do dnsmasq type functionality so that' a win if you need it.
- Billion 3G failover is miles better. This is poor on the Zyxel. Takes ages to switchover and the connectivity speeds are awful. Zyxel say only the cards on their list are known to work. Mine's a pretty common Hauwei so it should work. Anyway.
- Billion VDSL modem is rock solid. It also allows you to have multiple VDSL connections configured at the same time. So super easy to switch to another ISP. The same is available on the Zyxel but more primitive.
- Billion has one 1Gb Ethernet port. Zyxel (model quoted) has none.
- Support on both actually sucks. Billion's is marginally worse actually. With them you have to request firmware downloads
. The tech doesn't know anything about the modem. The prior person did. With Zyxel everything is - well it depends on interference. Well my Netgear, which died, didn't have any such issues
. Also the Zyxel is known to be unusable out the box. It needs a firmware upgrade. Oh yeah ... and if you encounter any issues on the Zyxel they ask you to re-setup from scratch rather than reloading a saved config. Clearly not confident in their software
.
So I've bought an RT-AC68U in an attempt to resolve poor WiFi coverage / latency issues.
Costs as much as the DSL-AC68U, but it's nice having separate devices.
Managed to link them via WDS. Works ok'ish. Get up to 20mbps but it's erratic. Still trying to get it to work in a more stable manner. If I can't I'll link them up wired. But for now I'm trying.
Hope that helps.
