Why does rebooting the modem and router make the connection run faster?

[Elliah]

erm...i'm sorry if this seems like an irrelevant question but my internet connection gradually decreased in speed until it couldn't even load up google...so in frustration i turned off my modem and wireless router...after i turned them on again my connection went back to normal...i wonder why?

It does the same as this, from Start-->Run--CMD

ipconfig /release
ipconfig /flushdns
ipconfig /registerdns
ipconfig /renew
net stop "DNS Client"
net start "DNS Client"

Just cache built up usually, also try clearing out all temp files with CCleaner

It's the router, not the modem. Routers have LOGGING capability and some have filtering.
These features use the same internal memory that is needed for i/o buffers.

1- update the router firmware
2-stop all logging or have it emailed daily
3- reduce your filtering to the absolute minimum or better yet, stop filtering altogether
(letting your firewall deal with the issues)
