I have instability problems with my home network, and I don't know what to do, because there are too many ways to configure my modem and my router. What's the best way to connect a router to a DSL (phone cable) modem?
For "instability" I mean: network speed is ok (I've taken some online speed tests) but it's impossible to watch youtube videos and google.com takes 30 seconds to show up; there are random disconnections; computers do not see each other on the network 50% of the time, so I have to restart the router and the modem to sync two computers.
Basically I don't grasp basic concepts such as "network segment", "subnet mask", and the various protocols involved. I could read books about networking, but it seems overkill. I don't want to tinker with technical details if what I want to do is basic functionality. Also, I'd like such simple components to work flawlessly, like a car, a bicycle, an oven. They should work without too much technical knowledge, or at least there should be a comprehensive manual for operating them. The included manual, instead, is basically a list of the available options on the web interface, without substantial content.
D-Link tech support is absent: they don't answer to e-mail, their online self-help site is broken (tried either with Firefox and IE), phone support is ridicolously expensive.
The modem is a D-Link DSL 320B (one ethernet output, DHCP), the router a D-Link DIR 600 (4 wired ethernet, Wireless N, DHCP).
I can set PPPoE (with user/password) and DHCP either on modem or router, the router has an "Access Point mode", the modem has a "bridge mode". I don't want to set static IPs because laptops are involved and I don't want to mess with the adapter configuration every time I use the laptop out of my house.
Can you please give some advice or useful links?
