8900AX R2 QOS configuration

I'm trying to use the 8900AX (firmware 2.50a.d21) to limit the WAN-to-LAN (downstream) bandwidth to an IP range.

I assume this is the most common requirement of it (e.g. limiting bandwidth use for some of family).

What i want to achieve is limiting bandwidth for an IP range to either a low priority or say 50%. Just need a priority, not a strict limit: if there are no users on fixed IP addresses, then those on limited IP range should be able to use 100% of bandwidth.

LAN to WAN has 3 options (Limited, Prioritisation, set DSCP marking)
WAN to LAN only has 2 options (Limited, set DSCP marking)

I may have misunderstood how to do this, but I'd assume I'd need the option 'prioritisation' available for WAN to LAN?

Q1 Is this not implemented?
If not, and 'limited' should be used instead, then can you advise how this functions?
e.g. if I limit an IP range to 50%,

Q2 - will that be 50% of whatever real bandwidth I'm getting ('real' bandwidth varies by time of day) or is it just based on the EWAN line speed entered?

Q3 - if at a point in time, the only user is one on the 'limited' range, will they be able to use the whole real bandwidth, or will they be unnecessarily limited to only 50% still.

1. Yes, if you limit the IP range to 50% they will get 50% of bandwidth all the time

2. If you are using the EWAN port then you are limiting the speeds based on the speed entered, if using DSL, it will based of the sync speed

3. They will be limited to 50% as the WAN to LAN does not have a Prioritisation option

Many thanks for the reply - and sorry for my delay responding; been away.

It sound like there probably isn't a way to achieve what I was hoping for then. It was as follows:

Essentially, when there is no competition I don't mind what is used on the main or guest wireless, or any IP addresses.

When there is competition, I'd have liked one of the wireless networks (or range of IP addresses) to get 75% of the bandwidth. The guest networks (or IP addresses outside of the range) will all share the remaining 25%.

Is there any way that is possible?

Unfortunately not, you can only set Prioritisation for the upstream
