The WiFi on this unit is totally intermittent, generally lasts for about a week, sometimes less. I've seen the dropout and failed re-association on various devices from different manufacturers, nVidia Shield (Broadcom BCM4354), Huawei Honor 10, Samsung S9 (Broadcom BCM43570), PS4 (Marvell Avastar 88W8797) to name a few.
A reboot of the unit always fixes the issue but also toggling the WiFi switch on the back of the unit does the same without a lengthy reboot.
It doesn't appear to be DHCP related as wired clients behave OK, a poster on another forum suggested that the unit was just refusing the PSK - I tend to agree with this as I have seen errors on some mobile devices showing the key has not been accepted, but then subsequent connections time out as if the client has been banned.
The latest change log doesn't list any sort of wireless client association issue https://www.cisco.com/c/dam/en/us/td/docs/routers/csbr/RV260/Release_notes/RV16x_Rv26x_relnote_v1_0_00_17.pdf
Has anyone else encountered these issues? How can we get Cisco to pay some attention to this?
This is a shameless re-post from the routing forum, https://community.cisco.com/t5/routing/rv260w-wifi-stops-working-after-some-time/m-p/3987940
There's also a lengthy blog https://www.davidlimonline.com/blog/2020/2/12/cisco-rv260w-small-business-router-fails-to-deliver which talks specifically about this issue and general poor WiFi performance.
The RV340W has had similar WiFi issues in the past with performance, not sure about stability, but those posts have received some coverage from Cisco employees; https://community.cisco.com/t5/small-business-routers/rv340w-5g-wireless-no-connection/td-p/3356780
