questionsis it ok to have 2 routers on one dsl line?


And now, reading up on it a bit, I see that the Vz modem/router does support WPA/2 encryption after all. Maybe I should have read up on this before springing for the new router -- could've saved myself 50 bucks! (OK, the new one is dandy and has a USB port for my backup drive -- that's gotta be worth $50 right there, right?)


You're not going to hurt your throughput much. Your latency might take a little hit. You could try a before and after test using

Bridge mode reduces a bit of overhead and might improve latency, but unless you're forwarding ports to computers behind your router, it won't make much difference for you. Or if you use apps that use UPnP (not very many do) - I'm not sure if that would still work correctly.

Bridge mode also eliminates CPU processing for individual connections going through it. So if the VZ router has a slow CPU or low RAM or a low connection limit, it won't handle things like bittorrent well unless you put a router behind it and set it to bridge mode.


@omnichad: Thanks, that helps. Bittorrent isn't an issue for me. We really just have a typical, boring household, and the 3 routers we've had, over the years, have all seemed sufficient to their tasks. Streaming via the Roku or the laptop being probably the most demanding use, and those are both fine. (And apparently not considered to be particularly demanding.) The thing with the most stuttering is when we watch youtubes via our old Tivo, but I don't know if it's correct to pin the blame for that on my network. Not so bad that I can't live with it, in any case.

ps Now I have to look up latency -- I told you I don't know a lot!


@infrom: Most of the modem or all in one models from the ISPs are limited locked down from the capabilities of the more expanded routers. This is why for my customers I always suggest getting a basic wired modem and then use the wireless and capabilities of an decent router. If the all in one is the only option then turn off the wireless and extra options, letting the router handle as much as possible.


@screwball bandwidth is how much data you can move per unit of time, latency is how long it takes to get all the data you need completely moved. There's an old joke (that only a nerd could love) about how you can't beat the bandwidth of a transport truck full of disk drives but the latency will kill you....

An analogy might go as follows: if you want to move 40 school children from a school to a basketball game across town a 2 seater sports car might have a higher speed than a 40 passenger bus, but the bus can do it all in one trip and thus will have lower latency over all. In your case, the extra router is adding an extra spot for parts of the network to communicate with. Sorta like having a 20 seater bus make two trips to transport the kids (but the bus is moving a couple 1000 miles per hour)....


Thanks for those two replies as well.


There must be some way to turn the "router" functions of the Verzion box off and turn it into a plain cable/dsl modem. Can you give use the model number and maybe we can help you? I've fought with various and sundry companies, most recently ATT when I had Uverse. I did some research and was able to turn off the routing functions and use a regular router.


Whoops, directed my reply at the wrong person. Sorry about that, but it looks like you figured it out that it was meant for you...


The worst case scenario is that the extra router will add an extra point of failure. The other information here is correct, but for home use your latency and throughput for a wired network is negligibly changed. If you have multiple wired computers and they have Gigabit and you throw them on a 100Mb switch (router) then you will see a decrease in speed transfers between those computers, but most people don't have gigabit routers/switches anyway at home (some do but most do not).

In any case, I ran multiple routers behind the DSL or Cable Modem frequently without any issues. You should be good-to-go.


@wilfbrim: Thanks for the offer! I tried working through Verizon's software, and came up against the need for a password at one point, which stymied me, since none of the ones I was aware of would allow me to proceed. But if, as rbarger suggests, the difference is negligible, I think I'll leave things as they are for the time being. The kind of advice that says "do nothing and you'll be fine" is always music to my ears!
