Hi there - thanks for replying so quickly. Sorry I probably did not explain myself very well.
My WAN comes from my BT Homehub which is plugged into WAN1 on the 2925.
The SureSignal is a LAN client - it is a Vodafone Picocell which transmits my mobile phone signal over the broadband line. It is plugged into one of the LAN ports on the 2925, and is operating correctly, but needs a guaranteed 50kb/s or so of upstream bandwidth. I only get about 400kb/s upstream (7Mb/s downstream) on my broadband line and if anything else is uploading (e.g. my Mac uploading photos to iCloud), the quality of speech on my mobile phone is severely impacted as the upstream 50kb/s required by the SureSignal gets impacted by the Mac hogging the bandwidth.
Last night I managed to use the "Bandwidth Limit" feature to cap other LAN clients to say 100kb/s of upstream and that meant I had good quality speech on the mobile phone as the SureSignal got the bandwidth it needed. However I don't want to limit the other clients if I don't have to and I understand this is where QoS can help.
I'd like to use the QoS feature - I've been trying to follow the manual and if I understand correctly, the concept is as follows:
1. Define a class for the SureSignal using its IP address
2. Allocate a percentage of the upstream and downstream bandwidths to it
3. Define classes for other types of client as per their IP addresses
However so far when trying this the quality of speech on the mobile phone using the SureSignal is not as good as using the bandwidth limit feature so not sure I am doing it right.
Not sure if I am using the right terminology here but hopefully that makes some sort of sense!
