WE826 with MC7455; router will not ping out

[bhalte]

HI,
i'm being daft and i'm missing something. TIA!

WiFIx WE826 Kernel 4.14.131
MC7455 Sierra modem
AT&T SIM:

Modem Connects fine and i'm getting fair RSRP, RSRQ and SINR values from at!gstatus? command...

Lan0 defaults to 192.168.1.1/24 (no GW however)
wwan0 has and IP, SM, GW & dns1 populated (automatically)

However from network->diagnostics
entry is populated w/ www.google.com
I click PING
I get message: ping: bad address 'www.google.com'

so..i think DNS....change the URL to 172.217.12.4 (via nslookup)
Click PING
I get message: Packets: Sent = 5, Received = 0

missing something...any guidance appreciated.
Thanks!

Your issue could be the domain you're trying to ping.
Namely, if you ping WWW.google.com with the prefix "www.", you'll get an error.
C:\>ping wwww.google.com
Ping request could not find host wwww.google.com. Please check the name and try again.

Pinging without the "www." prefix, should result in this:
C:\>ping google.com
