I have a Linksys Ac1200+ router that I seemed to have suddenly lost
WIFI access to. My router connection name no longer appears in my

Internet access. I've checked router settings, and WIFI appears to be
enabled for both bands. I've turned the router off and then back on,
as well as unhooked my Internet network cable, but WIFI still won't
show on my laptop listings. My other wireless routers work fine and
show up. What could be the problem? Thanks.

If the unit has the ability to "back up" a profile, I'd
start by doing that.

Then, I'd deliver the RESET sequence to the thing, and configure
it from scratch. Maybe there is a bit set somewhere which is
disabling the radios for example, a setting which doesn't have
a counterpart in the web interface.

If it has band selectors, you could also try disabling and re-enabling
the bands individually.

When my Linksys product failed years ago, I took it all apart, and
verified the connectors were all seated. It didn't help, because
the firmware bricked, and the path to reload the firmware,
gets broken when the unit bricks. Which at the time, I thought to
be a really clever feature. I could not think of a good way to bypass
that path, so it sits dead in my junk closet. I suppose I could
have unsoldered the flash, but... too much work :-) The $40 router
that replaced it, more than made up for it.

Not sure how or why, but it seems to be connecting again. I didn't do
anything other than the above, and that was all yesterday. Time will
tell I guess if the problem resurfaces. Definitely an odd occurrence.
Thanks for your response.
