Any idea what happened (wifi acted up)

[evilkitty]

I have 2 access points, one a U6-LR and WZR-300HP running DD-WRT v3.0-r28444 (has had stable wifi since 2015)

and i am trying to work on my PICO W and it suddenly would not connect and my computer had a very hard time connecting and my dad had been complained about his phone connecting

so i ran a wifi scan script on the pico and it just hang for several seconds and found nothing, normally it would spit out every AP in under a second (both of mine and some neighbors)

What i did was just install a U6-Lite that i had not gotten around to installing to replace the WZR300HP

any idea what happened, was the old router just jamming up wifi somehow?

Re: Any idea what happened (wifi acted up)

wifi, BT and several other things share the same rough frequencies - i'm surprised stuff doesnt get jammed a lot more often.

also, wifi modules/chips do burn out from heat over time.
when i used to hammer the local airwaves doing "exploration" i could kill a wifi dongle in a matter of months!

If it is connected with internet, maybe automatic update firmware is go bad.
Can you connect to device to check last update?

same fw i installed the week it came out in 2015, affected all clients, some more resilient than others

the only thing i guess is the router's wifi failed in some horrible manor, i just turned the wireless off on it, now it is just acting as a 5 port gigabit switch

I suggest trying another adapter before anything else .

Re: Any idea what happened (wifi acted up)

have not opened it, IIRC it has security torx screws, i do have a ifixit manta kit so i should have whatever it is, but the hardware is still in service on switch duty, for all i know the wall wort is degrading and can no longer handle the power demand for wifi

multiple clients were affected (all of them) it is not a adapter issue

bad caps in routers is common

Re: Any idea what happened (wifi acted up)

I would also recommend checking the capacitors in the router and the power supply as well I have had this issue several times in the past and if you do not find anything wrong with this ( using an ESR meter to check the capacitors ) then your router is just going bad and it time for a new one
