I am running an old WRT54GS with the Teaman mod of the Tomato firmware »en.wikipedia.org/wiki/Tomato_%28 ··· mparison
. I would upgrade to a Netgear WNR3500L V1 for around $30 which supports the Shibby Tomato firmware and Gigabit ports, but I am on the preferred 31/6 plan so the router is not the bottleneck.
During off peak hours, my sb5101u peaked at 34 Megabits down and 8 up before Cox's speed upgrade. After the upgrade the downstream was the same, but the peak up was 12.
I purchased a used DPC3010 on ebay for $34. I noticed peak upsteams of 16 megabits (then dropping to 6) and the same 34 megabits down. Since it is a DOCSIS 3.0 modem, the 8 channels down and 3 up maintain the high speeds during peak hours (vs dropping down to 6 megabits down). I would never get this high speeds during the evenings without the DOCSIS 3.0 modem »speedtest.net/result/2507307296. ··· 7296.png
