Can't Ping from PC to 2950 Switch or Switch to PC

[milton06]

Newbie preparing for CCNA....I have a simple network lab with a laptop and 2950 switch. I am connected via console port of the switch and also connected a ethernet cable from fa 0/1 to PC. I can see my laptop's mac address in switch's mac address by "show mac address-table'. However, I can't ping neither from laptop nor from switch using telnet. By the way, my laptop also connected to internet via wireless not sure if this is causing any conflict. Appreciated your help.

Could not copy the full config file.

If you are just running VLAN1, why do you have :-

Fa0/1 - switchport mode access

Take that off, it is not required.

All switches default to VLAN 1. In the real World this is not an ideal scenario. VLAN 1 shouild be shutdown and another management VLAN created.

Switchport mode access is normally a requirement for an edge switch (Such as a 2950 like you have), but take off that command.

As long as your laptop Nic is in the 192.168.1.xxx / 24 network range then there should be no issue, even with your wireless card on.
Also, I would use the "service password-encryption" command so that when you issue a show run, all your passwords show as encrypted and not plain text.

If your laptop is in the correct subnet, look at the laptop's firewall settings.

The switch looks fine.

Check your laptop IP settings.

Do a "show int" on f0/1

Do a ipconfig /all on the laptop

I have diabled my antivirus and I can't still ping in either direction. I am begining to think it is probably the cable, I am using CAT 5E which was bought along with the switch. Is this the right cable to use?

Thanks Vince and allworxguy. Changed the vlan1 ip to 169.254.145.177 mask to 255.255.0.0
and default gateway to 169.254.1.1
I think the root cause of this problem, I was using my wireless lan network's mask and default gateway rather than my eithernet lan's mask and default gateway (which I just assigned to my laptop). works from both directions.
If this was not correct analysis, please help me understand.

You assigned your address to your wireless card not the ethernet adaptor !!!
