Cascading Routers for different wireless mode?

    Here is the situation.

    1. All devices at Home are N except Tivo (G)
    2. Have 2 Routers (Asus RT-N16 & Asus RT-N12)

    Is it possible to cascade the two routers together so the N16 is in N mode, N12 is in G mode and both have different ssid? If possible, would that still bring the speed of the entire network down to G or since its separate, N devices would communicate at that speed even though there is G devices present but on a different ssid?

    It isn't actually cascading anymore if they have different SSIDs, right?

    Well, from my limited testing here is what I was able to do.

    N16 N Mode – SSID1
    N12 G Mode – SSID2
    N12 LAN --> N16 LAN
    Comp --> N12 LAN = get internet access on comp.
    Tivo see N12 SSID2 but can’t get IP address

    So if Tivo can see N12 and somehow I can get it to connect, then wouldn’t it operate on a different wireless mode and not drag down the speed of devices connect to the N16?

    Yes, but you're still sharing the spectrum, so it will be less than ideal (as compared to a true 2.4/5 dual-mode setup). From what I've read (I do not yet have my N16), the slowdown penalty to N devices by G devices sharing the same infrastructure isn't that bad (at least compared to B-on-G). However, in theory, your setup should indeed accomplish what you want.

    Well, I was able to connect the Tivo to the N12 at G and other devices to the N16 at N but the speed issue is still there. I don't think I will be able to get a significant boost on wireless speed unless I'm going to 5ghz cause I counted about 30 other AP when doing the wireless channel survey.

    I think you are right, but your speed issue may not necessarily be because of your own setup, but rather as a results of all those APs around you. The other APs show up on your APs as noise, causing several retransmits in your APs. 5GHz (or wires) is probably the way to go.
