Model: Archer A9  
Hardware Version: V6
Firmware Version: latest

I have both 2 ghz and 5 ghz wi fi and  wired lan enabled along with Dynamic Host Configuration Protocol.  I set starting address to 192,168,0,100 to 192,168,0,249  Address lease 1200

 

I have pretty much all on Dynamic Host Configuration Protocol

 

Four 2 ghz smart plugs

six or so 2 ghz Ring, generator, maybe Roku rarely used or is it 5 ghz?

 

Three 5 ghz two laptops, Kindle Fire,  maybe two Alexa on it?, two phones

 

Three wired Roku, desktop and a desktop computer as a media center (this one is non Dynamic Host Configuration Protocol set to 192,168,0,3 if I recall).

 

The problem I have my wife uses her laptop once every few days or perhaps not very often.  Sometimes when she turns it on, she cannot get to the internet.  From what I remember, I tried pinging the router and it seemed like it would work, but pinging some valid site, it would not (it works from my desktop).  I tried rebooting and the old ipconfig release and renew, but that didn't work.  Her previous laptop did this.  I even had a USB 5 ghz antenna and tried that on both old laptop and new, but still same results. I also tried manual ip assignment, but   that resulted in issues too.  It's Windows 11 (prior was Win 10)...  She is about 20 feet away through two walls. The generator is the furthest and works ok on 2  ghz network.

 

 

Maybe I need a lower address lease?  Maybe reboot router daily? Any other ideas?

  @Scotty_21,

I dont think the lease should have an effect, as it will either continue using the lease or request a new lease.

 

I am surprised that the cmd prompt didn't fix the issue on the spot. Next time, try either disabling the network adapter, or forgetting and reconnecting to the network. Forcing your phone to authenticate with the router may be the temporary fix. 

 

 

For your non-DHCP devices, these devices have proper settings in your Router UI and are not simply set on your Media Center, correct? If the addresses don't all line up, you may be having IP conflicts. Plus, normally IP reservations create a more stable connection - the fact that you had issues shows that there is something else causing a problem.
