Hi all, soon to be OpenWRT newbie here. I've been meaning to get a *WRT compatible router for years now but it's never worked out timing-wise until now. So I'm looking at the Linksys WRT series and it looks like my choices are the WRT1900ACS and the WRT3200ACM. From what I can see the headline differences are the 1900 has 128MB flash and 1300MHz bandwidth @ 5GHz while the 3200 has 256MB and 2600MHz bandwidth @ 5GHz... does that pretty much summarize the main spec differences?
Does the extra flash make any significant difference in capability (i.e. in terms of the number of typical packages loaded into flash etc... do people find the 1900 limiting in that respect?) Also, in reading through a bunch of forum posts and bug reports, it seems like the 1900 has reached a higher relative level of stability vs the 3200 when it comes to wifi... is that a fair statement? (One of the issues I've seen reported which is a concern is Android device compatibility... is that still an issue? If so, is it specific to the 3200 or does the 1900 also have it?)
Should it help re: recommendations/feedback, here's my hardware situation and use case:
- I'm primarily looking for high switch performance with low CPU utilization on the router as I'll usually have 2-3 1000mbps wired devices and the balance 100mbps wired devices plugged in and all fairly active.
- I've also got wide variety of wifi devices (usually only 2-3 are active) but mostly older (I think I might have one ac device, the rest are n (2.4 and 5) or even g) and I tend to run 1-2 generations behind the state of the art on this front and run the devices until they die. So I need a high degree of compatibility with devices but don't need a large number of simultaneous devices or tremendous bandwidth. (worst case usage scenario will be needing to do large file copies to/from a laptop when all wired ports are in use)
- I don't have a need for terribly high Internet bandwidth (I'm at 25mbps now and can't see going above 100 during the life of the router)
- Probably 90% of my traffic is LAN-based and some of the things I'm looking at using the router for are: probing/monitoring traffic, firewall and routing customization, serving files via a disk on the USB port (anyone running a linux mirror on their router? Interested is seeing any posts related to this), sniffing traffic via wireshark, running some simple web services, and occasional VPN use. So a bit of variety, but nothing too radical.
Any of the things I've listed a concern re: the 1900 or the 3200 or that would cause you to want to look at something else entirely?
 I normally wouldn't even mention this but one of the things I'm really fuzzy about in general with OpenWRT is what hardware features are unavailable due to lack of driver support pushing work on to the CPU. This is a concern both from the standpoint of relative power consumption of the device (vs stock firmware) as well as CPU headroom for other tasks.
Thanks in advance,
