Hello HTG. I enjoyed the recent (and on-going ?) tutorial on Photoshop. I was hoping someone could run a (series of) tutorials on intermediate networking - specifically directed at Verizon FioS, but routers in general would be fine. I'm sure I'm not the only reader using their service/rooter who would like to understand what I see "under-the-hood". I understand some of the basics, but not all of the functions. For instance, (in my case at least) the DHCP Server assigns the local IP Address to specific MAC Addresses. But does it assign Subnet Masks, too. Or is there only one. And how is this different from a DHCP Relay? Why are there bother Primary and Secondary DNS Servers? When do I want a static address vs. a dynamic one and why is there an expiration time at all. QoS? DMZ? SIP ALG? Multicast IGMP Filtering?
Most routers give a little blurb for a field or setting. Sometimes nothing but a numeric range. But things are never actually explained. Everyone just uses the defaults and hopes it works. I've used routers by Linksys, Netgear, D-Link, Cisco, Belkin, and this one from Verizon FioS. I would love something more like a paragraph or two on these features.
As an aside, (though the above rant was prompted by it), my wireless connection mysteriously stopped working today after a year with out problems. it took 3 1/2 hours of poking around with all the standard power checking, rebooting, SSID and Encryption checking, retyping of passwords - both by keyboard and cut/paste, driver checking, etc. Finally I changed the password from my nice randomly generated 64 character WPA2 password to "TESTWIFI" and then back again to the previous 64 characters. That's it. It shouldn't have worked or even mattered. It's fixed but not solved. So, HTG... Why?
Thanks in advance.
