Well. A site issue can hopefully be fixed. Time is money and yeah, the first idea was to just install dd-wrt, openwrt, tomato flavors. Funky processor and no support for the thing. So I gave them an AP in the form of an old router to use until we came up with a solution. Besides paying the bill I got a fish dinner and a mess of beers and the router stayed until finding a new fw release for theirs that fixed the issue. There was no shell access on it, of couse.
Me. I tend to go in and find and fix the issue w/o dissecting it to the last electron. You know.
Yeah, you never mentioned what Linksys model router it was. But with dd-wrt, openwrt, tomato, it will actually be slower because all of those do not contain the Broadcom Driver which is paid and license so the hardware acceleration will not be enabled. So a 300Mbps normal speed will be at 190Mbps or so without the hardware acceleration. I thought they somehow they were actually still using their own router afterwards. I guess depending on what model it is, there is actually a better firmware than even Linksys's stock firmware which has the Broadcom Driver in it, that's a ported version of R-Merlin's ASUS software but you need to have specific models of the LinkSys router(s) for that to work from either XWRT-Vortex available at
Home | Xwrt-Vortex which is more limited and only supports the EA6900 or Koolshare which supports over 80 models of Netgear and Linksys routers. Koolshare is available at
Merlin-Koolshare Routers - WannaFlix but only supports Linksys router models EA6200, EA6400, EA6500v2, EA6700, EA6900. I usually mess with different software parts only and will go third party as needed since the only reason one needs to even dissect it
is to connect it to the serial port manually to reflash it if there is no other way to do it which usually means a bad flash. The other thing you can do is downgrade the Linksys stock software but it is not direct from Linksys stock to Linksys as that's not possible. What you need to do is install dd-wrt, openwrt, tomato flavors and then switch back to the Linksys software version of your choice but it seems Linksys provided the following to downgrade the software:

Shell access would depend on the model as on some, you can enable telnet and then telnet to the router for the shell access.
