I have been running with two WNDR-3800 (one on each floor) in my home for several years. They are running hnyman's build of OpenWRT.
If my budget is about $100/router and I want to run LEDE, what would you recommend as a replacement? We have lots of wireless devices. Comcast recently increased my Blast! Internet to 200M so I'd like something fast enough to handle this.
I currently see around 120M using a SB6120 cable modem, but recently purchased an SB6183 hoping that additional downstream channels would give me more speed.
What is the exact problem with DIR-860L and SQM? I read there is a problem with the driver. Is it connected to the WiFi or the Mediatek CPU? I also read that the 2.4Ghz WiFi is really bad on this router.
Because if you like the WiFi performance of WNDR-3800 then you might want to consider keeping them as dumb AP and buying Ubiquiti EdgeRouter X (no WiFi, only Ethernet) as main router.
Well, this comment in particular was about Broadcom's 802.11n platforms. While some of them do work with open wireless drivers, it makes little sense to recommend them nowadays when better 802.11n solutions (ath9k) or cheaper 80.11ac solutions (mt76) are available.
Wireless drivers for their more recent platforms are closed (similarly to what Atheros has done with ath10k). Like their 802.11n solutions, only specific Broadcom AC hardware is supported by the Linux kernel (with most functionality and 'IP' tucked away in the binary firmware blob).
