About six months ago I started to notice lag and dropped packets from my internet connection. It's not that noticeable when I'm browsing the internet or YouTube, but when I'm play games such as Diablo 3, WoW or Team Fortress 2 it gets bad. Six months ago - and prior - I averaged around 100-200 MS/Ping. Now? Now it starts at around 150-250, will shoot up to 400-600, back to 200-400 and I've even saw it shoot up as high as 1700+ ms/ping. Why? What causes dropped packets and what can I do to fix it?
Do I need to replace the modem? Would a cordless phone that is also plugged in cause this?
Also, one more thing, when it rains (like the rain we had here in So. Cali) the entire internet will drop, including the phone. When I pick up the phone all I hear is static. It will last around 1-3 hours before finally being able to near the dial tone and be able to use the internet.
Both of these are seperare incidenes.
