Sorry if this sounds like a n00b question , but I am pretty much a n00b when it comes to this... My home network is running a WRT54G v5 running DD-WRT v23sp2 micro firmware with 4-5 clients (fixed IPs in the 192.168.2.x range ) connecting to it. The WAN connection is from an ISP called Airtel (India) which provides me 256/128 kbps from 9:00AM-9:00PM and 512/256 from 9:00PM-9:00AM Am thinking of setting up QoS (Quality of service ) rules on my home network as am pained by manually slowing down torrents whenever I need to browse or use VoIP However, have a few doubts and would appreciate the help of anyone who has any experience on this... While setting up the QoS rules, let us say I Allocate torrents service to Bulk, Http to standard and VoIP to premium or express. This would leave me with specifying the maximum upload and download limits, which I presume the router will use for the bandwidth allocation calculations.. Now since my connection is @ 256kbps (day) and 512kbps (night), what happens if: A) If i were to set 256 as my d/l speed, would the router still allocate the full available bandwidth (512) to torrents at night when no other network activity is happening? or is it that since I have set 256 as the d/l speed, the router would throttle the available bandwidth to 256 for torrents thereby leaving the remaining 256 unutilized? B) If I were to set 512 as my d/l speed, I suppose the router would allocate all the avilable bandwidth (512) to torrents at night, but during the day, when the speed is 256, the router would still allocate a more than necessary bandwidth to Torrents (On a base calculation of 512) and leave little room for the higher priority services ANy suggestions welcome!
