WRT54G w/DD-WRT Headache

OK, here is my setup:

I have Verizon FIOS with the Actiontec Router acting as MOCA and servicing my wired devices. I have the Radio disabled in the Actiontec and instead have a Linksys WRT54G v8.2 connected from port 1 of the Actiontec to port 1 of the Linksys. The Linksys has a static IP of 192.168.5.1 set, DHCP disabled and is configured to provide wireless to the remote reaches of my house. This setup has worked fine for a few months.

After reading about the capabilities of DD-WRT and the uses for the T-Mobile router featured recently in the Hot Deals Forum I decided to set up a WDS. First step was to flash my current WRT54G v8.2 and the new T-mobile router with the new firmware. No problem there both flashed fine. However, when I started to set my network back up I ran into a problem. When I configure the WRT54G like it has been for months all seems fine, I can get internet on all the machines (even though speed is worse, separate issue) no problem. But I can't get back into the web configuration page for DD-WRT. I've done the 30-30-30 reset a few times and initially all works fine, I can setup the router and all is well but after I exit the configuration page I can't back in either wired or wirelessly. I've ensured that both options in the "Remote Access" section of the Administration Tab are enabled so I'm at a loss.

Any help will be much appreciated.
 
Which one of the linksys devices is having the issue?
The WRT54G 8.2 has only 2mb of flash memory based upon the DD-WRT wiki.
Did you make sure to install the micro version on that one?
The T-mobile version has alot more flash memory 32mb i think.
 
The WRT54G v8.2 is being the problem. I've not even attempted to setup the WDS yet with T-mobile unit.

I used the following to flash of the WRT54G v8.2:

vxworkskillerGv8-v3
dd-wrt.v24_micro_generic


 
Can you telnet in?
I'm guessing it doesn't even get to the point of asking for userid😛ass?

so your network is:
Actionec--->wrt54g v8.2(dhcp disabled)--WDS-->wrt54g-tm ?

If it is, I would switch the wrt54g v8.2 and the TM one. The TM has more memory so it more capable as a router, while the v8.2 will work as a AP perfectly fine.

I guess the DHCP is disabled? If so are the routers on the same network (ie 192.168.1.*)?
 
I've tried both in position after the Actiontec. It seems that once I connect it to the Actiontec I can no longer access the web configuration page without unhooking it and resetting it.
 
If I have the Linksys set to 192.168.5.1 does that put it into a different subnet from the rest of the network that is in the 192.168.1.XXX range? I set it to 192.168.5.1 to get it out of the DHCP range of the Actiontec router.
 
If your linksys is set to 192.168.5.1 and your actiontec is 192.168.1.1 and the DHCP is turned off on linksys and you have the linksys connected from port 1 to port 1, your computers will not even be able to SEE the linksys. You need to turn on DHCP on the linksys and make the WAN port of the linksys is connected to the LAN (any of the LAN will do) port of the actiontec. If you want to leave it how you have it, physically, then you'll need to change your linksys IP to 192.168.1.x and make sure the x is something outside of the DHCP range of the actiontec (so the actiontec doesn't assign a DHCP IP address to a PC that happens to be the same as the linksys=IP address conflict).
 
So if I leave it configured as I have it and simply change the DHCP range in the Actiontec to end at 192.168.1.253 and then assign the Linksys an IP address of 192.168.1.254 that will allow me to see the Linksys?

There is your problem. They must be on the same network (not sure of the exact term here).
192.168.2.* won't easily communicate to 192.168.1.*

So set them to the same thing. Like, 192.168.1.1, 192.168.1.2, 192.168.1.3 and shut off the DHCP on the wrt54g or the actiontec.
You can also set the DHCP range to be above the router ip addresses. Like the 192.168.1.1** range.

Yep that would work.

btw, shouldn't the Actionteck be assigning ips in the 192.168.1.1** range?
Most routers I've messed with start at the 100s.

I would recommend changing the DHCP range on the actiontech to 192.168.1.100-150 and assign the linksys as 192.168.1.2 or anything between 192.168.1.2-99
 
Thanks everyone.

I changed the DHCP range on the Actiontec to 192.168.1.2 - 192.168.1.249.

Leaving 250-254 available for any routers I use for the WDS. That took care of the problem of not being able to access the web configuration pages. I haven't set up the WDS yet because I've been puzzled by the slow down I've experienced in my wireless network since I flashed the Linksys router to DD-WRT.

Before the flashing my laptop anywhere downstairs averaged between 12,000 & 14,000 kbps download and around 4600 kbps upload, as measured on speakeasy. Now I get between 7000 & 9000 download and still roughly the same upload.


 
I've tried both the WRT54G v8.2 and the WRT54G-TM with similar results. The v8.2 has the micro version but the TM version has the latest full version.

Is the Linksys Firmware that much more efficient that switching to DD-WRT on these models drops the performance by almost 40%?

Some suprises on speed (keep in mind that the test is being run on "wired" ports).

Make sure to read further into the thread as Bill has updated the numbers to included Tomato 1.23 (which is faster than 1.22 by quite a bit).
