I have searched for a solution to my problem and can't seem to find one (this site needs a search on "topic only" option). Any recommendations would be appreciated. I have a WRT54G and WRT54GS that are both version 4. I bought the GS solely to compare to the G since I thought it might have been a bad unit. Same problem on both using Bellsouth DSL 1.5/256. Testmyvoip.com to Boston gave a 4.4 MOS and lost packets result of 0.1% and about 150-170 ms round trip latency. Problem: I just got Vonage last weekend and I am trying to set QOS up so that downloading through newsgroups (port 119, 8000, or 9000) will not affect the Vonage. I have made the following unsuccessful trial adjustments while using the latest Linksys firmware, DDWRT v23, and HyperWRT Tofu 13b. I don't have much info on the outgoing voice quality while using newsgroups yet but I do on the incoming voice. The incoming is somewhat garbled unless I manually set the upload to 70 kbps or less out of a test available 210 kbps. While the newsgroups are downloading at full speed (150kB/s or so) the router will restrict the newsgroups to about 0 kbps if on a Vonage call and then pick back up after the call....... but only when set to <70 kbps on the upload. This is how I want it to work but it is not acceptable at <70 kbps setting. Unsuccessful adjustments tried: 1. Manually set upload to 80-210 kbps out of 210 available. 2. Used MAC QOS (set to highest) for the Vonage (Motorolla VT1005) 3. Used port QOS (set to highest) for the Vonage adapter 4. Used app QOS (set to low) on port 119 for newsgroups 5. used erase nvram; reboot and still I have broken up incoming voice quality when downloading newsgroups. I have read the QOS primer and understand it and how that the router cannot really do anything about incoming packets. But I have also read where others have "multiple p2p, IMs, internet usersâ€ etc and have "crystal clear" VOIP at the same time. I don't understand what they are doing and what I am not to get these excellent results. Are they only uploading and not downloading p2p at the time they are using VOIP? Sorry such a long post. Any ideas on how to improve incoming VOIP quality while using the full download capacity of a connection? Thanks.
