Windows 10: How Can A Notebook Be On The Lan But Not Seen By Router or Ping?

My son's school laptop works fine at home so it's on the lan alright, using the router.

But the router doesn't list it.

And I can't ping it.

And it doesn't ping my machine at home

ipconfig on his machine says 192.168.0.200

which is our lan subnet alright.



when he pings the router he gets 'request timed out' and then he gets three normal replies with TTL 45 or something.

I don't understand any of that. Can anyone explain what's happening to me? Is it normal? Has the school 'fixed ' his machine somehow?

:)

 

Good LAN party games?

Most of my suggestions have already been listed.

However, I found Swat4 to actually be a pretty fun LAN game, especially at smaller LAN parties.

 

Ping spikes in-game and to router.

other traffic on the lan can affect ping times. all depends on the quality of the router/switch.

haven't done much testing in a while on ip over power line recently. last time I did changes in powerusage on the same circuit affected bandwidth.

 

How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".
