I realize there is plenty of documentation on this subject throughout superuser and the internet overall. However, it's almost like there's too much information and I need help sorting through it.
For my specific situation, I have a TiVo HD in my living room with no wireless adapter, and my cable modem + wireless router in a separate room. Instead of spending the cash on a TiVo proprietary adapter, I decided to use my spare wireless router as the connection point (via ethernet cable) for the TiVo.
Both wireless routers are older models: Airlink AR430W and Buffalo WHR-G54S but both have been pretty well documented to work with DD-WRT if that's the route I need to go (no pun intended). They are interchangeable as far as I'm concerned, too. In other words, I don't mind moving either one to serve as the primary connection to the cable modem.
As far as superuser articles are concerned, here is the closest match to my situation that I can find:
And here is a good article on utilizing DD-WRT from makeuseof.com:
The only problem with either of these references is that the former is not specific to my hardware/software setup, and the latter is very general as well as being 2 years old (I don't know if the instructions for setting up DD-WRT have changed in that amount of time).
I started reading through the process of installing DD-WRT on my Airlink router first, but all of the cautions about "bricking" my equipment have made me put a hold on it until I get a better opinion. I'm not incredibly tech-savvy when it comes to electronics or programming.
Ultimately, I want to keep a wireless router connected to my cable modem in one room that transmits wirelessly to all devices including my laptop, iPad, and secondary wireless router at the TiVo. I don't care if the secondary router repeats the wireless signal, as long as I can get an ethernet connection out of it.
Is there just an easier way to do this?
