MS Nokia Lumina 928 can not connect to 2.4 GHz

[brendanfsmith]

I recently purchased R6400 AC1750 and setup with default settings.  Cable provider is cablevision optimum online. 

I have upgraded to firmware V1.0.1.20_1.0.16

We have multiple smart phones (iPhones) and a desktop connecting to the 2.4 wireless.  

However my other smartphone (Nokie Lumina 928) can not connect to the 2.4.  It does connect to the 5G.

I have tried a number of troubleshooting steps - reboot router, reset the phone, ensure phone is updated, change security settings, enable guest account, etc.

no good. 

Any suggestions ?  (besides telling my wife to get an iPhone?) 🙂

Thanks

Hi @brendanfsmith,

1. Please try connecting the Nokia phone to another 2.4GHz wireless network (coffee shop, office, etc.).

2. The option to change the time is under Advanced > Security > Schedule.

Hi @brendanfsmith,

We recommend doing a factory reset after updating the router's firmware. You can check the link below for the steps.

no luck

I tried factory reset on the router (twice) including rebooting the modem. 

the lumina will not connect to the 2.4.  it very quickly (within 2 secs) returns the "your phone cannot connect to the network".

some observations that may or may not be relevant

- while monitoring the Lumina list of available networks, the 2.4G network occasionally drops from the list for 5-10 secs, then comes back for 30-60 secs.  repeats.  5G seems to always be available 

- the netgear router logs do not show a failed login attempt (normal?)

- the netgear router clock shows 4 hours behind.  i am on eastern DST time.  no idea how to change the clock/timezone (probably irrelevant, but annoying) 

- i see some DoS logs [DoS attack: ACK Scan] (1) attack packets , and [DoS attack: Smurf] (1) attack packets

any suggestions would be greatly appreciated.

thanks
