I've got a Arris SB6141 cable modem. When I hardline into it, I get over 100 Mbps down and about 20 Mbps up. When I connect it to a Linksys N-Ultra WRT160N broadband router, I get 0.5 Mbps down and 12 (?!) Mbps up. What gives, and how can I get more speed through my router?
Electrical engineers and others with a pretty in-depth understanding of communications tech: why does Comcast have a specified minimum for transmission signal strength from cable modems on its network? Or a maximum for reception signal strength? [more inside]
What's the best option for high-speed internet access in San Francisco? (Moving from Castro to Potrero Hill, would like to ditch Comcast if there's a good alternative.) [more inside]
Is there a software program of some kind that will automatically monitor and analyze the health (i.e. transfer rate and up/down status) of a broadband Internet connection? Ideally like to see statistics graphed over the course of a week or so, tested every 1 to 15 minutes, so I can see what kind of quality I'm getting. I'm not sure if any software like this exists.
On a fairly regular basis, even if I'm in the middle of using it, my cable modem connection vanishes. Fixing it involves unplugging the modem and router, waiting a few minutes, replugging them and crossing my fingers. I gather this phenomenon is extremely common. What can I do to prevent it, and more importantly, why does it happen in the first place?
