Question Networking

That is question that is actually much more complex than you think. It likely is actually how many packets per second the device can pass and not how many mbps. The packets could be anywhere between 64-1500 bytes in length.

Still even very inexpensive routers can get 900+mbps on speedtest sites.

Now that is only if you use the router as a simple NAT router. As soon as you use other features the speed can drop a lot. Using things like firewall features or vpn takes a lot of cpu power.
 
Yes but modem it's not incombatible with a 100 mbps or 200 mbps connection. My question was for the modem part of the device if it can be used on a connection with the telephone company that it speed is about 100 or 200 mbps
 
I am not sure what you are asking then. I know of no dsl system that will go that fast in actual real world installations. I assumed you were going to use the ethernet wan port on the router.

DSL speeds is mostly dependent on the quality and length of the phone wires coming to your house. There are some specialized fiber/dsl implementation that can run somewhat faster but I doubt you will get anywhere near 200mbps.
 
A technician told me that the fiber connections can reach 100 or 200 mbps and that my dsl ac68u can't synchronise on those speeds and as he told me i must use the modem router supplied by the company. But I am not so sure if that is valid and I want to know if Asus can synchronise on fiber dsl connections on those speeds in general. I don't want to use other modems routers because I consider them inferior in many cases than mine
 
They maybe using a special form of dsl that the asus does not support. It really doesn't matter if it does if the ISP says they won't support it and you have to use their modem you have little choice. In general they have a list of devices that will work and if that router is not on the list they think it will not work.
 
It's working as I used it until 50 but I must buy another device for voip since Asus dont support voip but as I see I must pick another telephone company if I want to use my equipment in any case i wanted to know the top synchronisation speed of the modem because I don't want to be fooled by "technicians" who promote the equipment of their company...
