Any assist or advice would be greatly appreciated. I have read through other forum posts and websites trying to fix this myself and nothing has worked.
I have Mac OS High Sierra, iPad, iPhones on my network, Spectrum rented Ubee DVW32C1 router/modem combo. I am trying to maintain communication between these devices and my HP ENVY 7855. I have been able to have communication multiple times but then after several hours or overnight, the communication is lost. I have set a static IP on the printer, which ultimately failed. I have cancelled that and set a static IP within the router, failed. I have asked Spectrum if they would send me a different brand router and was told I could take this to a store to change it out but am wanting to see if there are any other suggestions before I do this.
you also need to set up the router so that the dhcp start is 192.168.0.100 and the printer is on 192.168.0.99 .
In the wireless, turn off scan and lock it on channel 3 or 8
That should eliminate the variables.
Do you mean running Ethernet cord from router to printer but will still be able to print from wireless devices?
HP printers are notorious for having wonky wifi connections. If your printer is direct connected to the router it will always be connected to the network. Your wireless devices should then always be able to find the printer on the network.
Verify the router was still on ch 3.... if it changed that's an issue. Normally, changing auto to a channel number turns off scan...
Next issue is the wireless dhcp lease time.. It needs to be set at a day not an hour.
And yes It will have a reliable connection on ethernet and provided that there's no AP isolation turned on, wireless and wired can talk to one another.
