Recovering

 

an

 

IP

 

Address

If

 

you

 

experience

 

trouble

 

communicating

 

with

 

the

 

access

 

point,

 

you

 

can

 

recover

 

a

 

static

 

IP

 

address

 

by

 

resetting

 

the

 

AP

 

configuration

 

to

 

the

 

factory

 

defaults

 

(see

 

“Resetting

 

the

 

Factory

 

Default

on

),

 

or

 

you

 

can

 

get

 

a

 

dynamically

 

assigned

 

address

 

by

 

connecting

 

the

 

AP

 

to

 

a

 

network

 

that

 

has

 

a

 

DHCP

 

server.

Discovering

 

a

 

Dynamically

 

Assigned

 

IP

 

Address

If

 

you

 

have

 

access

 

to

 

the

 

DHCP

 

server

 

on

 

your

 

network

 

and

 

know

 

the

 

MAC

 

address

 

of

 

your

 

AP,

 

you

 

can

 

view

 

the

 

new

 

IP

 

address

 

associated

 

with

 

the

 

MAC

 

address

 

of

 

the

 

AP.

 

If

 

you

 

do

 

not

 

have

 

access

 

to

 

the

 

DHCP

 

server

 

that

 

assigned

 

the

 

IP

 

address

 

to

 

the

 

AP

 

or

 

do

 

not

 

know

 

the

 

MAC

 

address

 

of

 

the

 

AP,

 

you

 

might

 

need

 

to

 

use

 

the

 

CLI

 

to

 

find

 

out

 

what

 

the

 

new

 

IP

 

address

 

is.

 

For

about

 

how

 

to
