Well, the original WRT54GL (Linux version with 8MiB RAM) cost me ~$50 when it was new, the WRT3200ACM is offered for $250. A descendant perhaps, but no replacement.

Yep, those are pretty much all I buy nowadays for home / small office routers. Absolutely rock solid.

Correct. That's why I sought it out and may or may not have baffled / actively disregarded the Best Buy sales guy who wanted to sell some other routing hardware that was 'newer'.

This message delivered to you with its help, and I am definitely going to be looking for its descendant when the time comes to replace this one....IF it is still open-source-ready.

Does OpenWRT implement some of the more obscure features, like MIMO and what not? I'm still using DDWRT on a Trendnet AC1750 supported router. I definitely don't need much more but I could use some bandwidth and power range for local transfers and such.

I used these before I switched to pfsense at my SMB. They're great. I use the WRT3200ACM at home + a UniFi AP for better range upstairs and have been very pleased.
