try hooking your old router into a free port on the new router(use the regular ports not the wan ports on both), set it up to use a diff IP address than the new router, also turn off the dhcp server on the old router but leave it on on the new one(if you use dhcp) and see if you can connect to the old router with the n800 and get internet access, may have to tinker with the various settings, I *think* I've done this before, or something similar, while "borrowing" and neighbors wifi

Sure, why not? Try connecting them up in a series. For instance:

[cable modem]---[B/G/N router]---[B/G router]

Depending upon the configuration of your B/G router in this scenario, devices connected to the B/G/N router may not be able to connect (SSH, SFTP, VNC, etc.) into devices connected to the B/G router, but going the other way will work.

If one of your routers can be switched into access point mode, then you're even better off.

Noticed something strange this morning. Before I updated the firmware on the N router (in mixed mode) my download speed was in the 7000 range. After the upgrade it is in the 5000 range which is the G range. I thought I could live with G if the download speed was going to be that high. Guess not.

I still think there must be a way to hook up two routers to the same cable modem.
Messing around with the preamble and MTU will help you optimize performance. On Verizon FiOS, an MTU of 1502 (if I recall) is recommended. I forgot what I set my various preambles to.

Having multiple routers and access points on the same cable modem is easily possible, just be careful which you set as your DHCP server. I've had conflicts when I forgot to turn off one DHCP server on my 802.11g router, which stomped on DHCP from my Verizon router.

For an example of how to configure multiple routers and wireless access points, here is what I'm running:
Code:
First floor:
Verizon FiOS router with 802.11g and 4-ports
 \_ 50-port Cisco Multilayer Switch via the Verizon FiOS router
      \_ multiple servers via Cisco switch
Second floor:
 \_ Linksys WRT54GS 802.11g router with 4-ports
 \_ DLink RangeBooster-N 802.11n router with 4-ports
      *  multiple laptops via 802.11n, 802.11g
Third floor:
 * Linksys 802.11g wireless bridge to 2nd floor
    \_ Linksys WRT54GS 802.11g router with 4-ports
    \_ multiple servers via Linksys WRT54GS wired ports
        * multiple laptops via 802.11g
Out of this whole network, DHCP runs on the Verizon FiOS router as well as a firewall. Network packet analyzers and IDS run on one of the unnamed servers. Other webservices, sftp, ssh run on a third.

As for using multiple routers on the same broadband connection: When I visit folks with wi-fi, instead of maybe getting my N800 added to their mac-access list, setting up my N800 for their wep/wpa/whatever etc., I simply plug my little travel wi-fi acces point (very small) into one of the ethernet ports in their (wi-fi or not) router and as my N800 and my Asus 330 already know each other I'm on the air. Very simple, and no bother for any of us.

TA-t3: Really? ...I've thought about doing the same for when I'm travelling for work (hotel room ethernet-to-wifi) and visiting family. At the time, the only portable WiFi AP I looked at was Apple's Airport Express.

What are you using? What would you recommend?

HOWTO: Set up USB networking with Windows (2000 and XP)
http://maemo.org/community/wiki/usbnetworkingwinxp/

At least with OS2007, I was able to take my USB cable and plug into a Windows 2000 or XP desktop to still access the net via a cheesy USB link. I haven't tried using the Ethernet-via-USB panel applet or scripts under OS2008.

I'm surprised I never thought of carrying a pocketable WiFi AP. The USB cable was handy, so I thought wired.

@promethh:
I use an Asus 330b. There's also the 330g. There are other brands. This has been discussed several times before, check out these threads - lots of info:

I concur with other regarding the mixed mode being a mess.

If I set my DIR-655 to mixed B/G/N not one B or G device/laptop will see it. D-Link has refused so far to acknowledge the issue, to me (they give you the denial and idiot treatment) but I know what I see & do ... and it doesn't work. Same thing with a couple of other features on that router/firmware.
