Internet Access by Wi-Fi From Ethernet?

kwikbreaks

Don't know about your Linksys which is the one I'd try for the job as that's the way it's intended to be used but certainly when I added a TP-Link AP (a TL-WA701ND) I had no need at all to power cycle my main router it was just a case of configuring it correctly.

I'd suggest you experiment by trying this out by trying both with your current main router to see if you can get it working. You'll maybe need to reconfigure it for the new setup when you move or maybe not.

I already have a spare Netgear DG834G ADSL modem router, and a LinkySys WRT54GL cable router (the latter has been flashed to the DD-WRT firmware).

I don't think the Netgear DG834 ADSL will work. Doesn't this have an RJ11 connector for connecting to the phone line?

You will need a 'cable' modem such as the WRT54GL you have.

You say you won't have access to the existing router which is where I assume the RJ45 cable comes from. Do we know the configuration? Is the RJ45 cable just plugged in to one of the switch ports on the back of the router? Assuming a standard dhcp setup on the existing router then YOUR router will request an IP address when it is powered up so you shouldn;t need to power off the existing one.

Use Your Mac as a Wi-Fi Hotspot and More

I did something similar with a carpy old ex TalkTalk Echolife adsl router.
You'll need a router with 'bridge' mode, Netgear dg834 should do.
I factory reset the Echolife, then found the bridge mode settings from the web, not forgetting disable dhcp.
I connected it directly to a pc, applied the settings. Turned both off, connected ethernet from main router to one of the Echolifes ports, then connected pc to another Echolife port.
It worked spot on.
I didn't have to power cycle main router because the secondary router acts like a switch, so is invisible. PC gets address from main router.
Wireless also worked, but didn't investigate that side of things.

Apologies for the rushed post.

you should be able to use the linksys without needing any access to the other router, just configure, plug in to the ethernet feed, and away you go with wifi.

The Mac thing was just a reference for anyone with one of those things reading the thread.

For XP, have you tried the simplest option? Turn Your XP Laptop into a Wi-Fi Hotspot Via an Ad-Hoc Network

Of course your phone may not even connect to the network and needing to have the laptop on all of the time may be inconvenient, but it's worth knowing if it works for you.

OK, thanks. Using the Linksys router, when configuring the wi-fi in DD-WRT (which is I think all I need to do), I'm faced with a number of options:
For 'Wireless Mode', do I select: AP, Client, Client Bridge, Adhoc, Repeater, or Repeater Bridge?
For 'Network Configuration', do I select Unbridged or Bridged?
Everything else seems straightforward.

If you are connecting into a wired lan then the Linksys in AP mode with DHCP server off should work.

Either of those routers configured in bridge mode will work fine.
