wifi: XP dont't ping mikrotik

RouterOS Wireless Networking
1

I have a Mikrotik RB751U-2HnD wifi router.

I connect a XP computer with wifi to this AP: I see the XP computer in winbox > Wireless > Registration (with the MAC address of my wifi interface on XP computer).

The firewall on XP was desactivated.

My XP can’t ping my mikrotik (and my mikrotik can’t ping my XP) !

I’ve disabled all rules in winbox > IP > Firewall > Filter Rules: no ping !

I’ve disabled NAT in winbox > IP > Firewall > NAT: no ping !

In winbox > Intrfaces > Interface: I see traffic on

I’m a little disappointed.

What’s happened ?

Thanks for all.

How is your XP interface configured? Does it use a static ip or dhcp? What ips are you using to ping?

Maybe you should post
/ip address
/ip route
/ip dhcp-server

I've just done a reset of the mikrotik.

I've connected my mikrotik with port number 5 on a 2003 server. With winbox, I've connected to the mikrotik successfully.

After, I've done: winbox > IP > Addresses > "+" > Address: 192.168.88.1/24 > Interface: ether5.

Then my 2003 (192.168.88.2) can ping the mikrotik.

After, I've done: winbox > wireless > interface > wlan 1 > right clic > enable.

Then: wireless > interface > wlan1 > wireless:

  • mode: ap bridge,
  • ssid: test
  • wireless protocol: 802.11
  • bridge mode: enabled

Then: wireless > security profiles > default :

  • general: mode: static key required
  • static keys: key 1: 0000000000
  • transmit key: key 1.

On my XP: I've put my wifi configuration:

  • ssid: test,
  • authentication: open,
  • cypher: wep
  • wep key: 00000
  • key index: 1.

The connection work fine:

  • XP say connexion is done,
  • on mikrotik: winbox > wireless > registration: i see my wifi xp card (with the good MAC address).

No firewall on my XP.

Now, the ping form XP to mikrotik:

XP IP wifi card configuration:

  • IP address: 192.168.88.10/8
  • non gateway,
  • DNS server: my 2003 (it's a domain controller: the goal is to make radius authentication).

route print:
192.168.88.0 255.255.255.0 192.168.88.10 192.168.88.10

And the ping to mikrotik (192.168.88.1) and to my 2003 (192.168.88.2) don't work.

Mikrotik seems to be a very interesting product, but i'm a little lost in all options available.

Thanks for all.

Best regards.

Maybe you should post
/ip address
/ip route
/ip dhcp-server

Better yet post /export compact

Here is:

[admin@MikroTik] > export compact

jan/02/1970 00:04:52 by RouterOS 5.14

software id = 2AYL-KERF

/interface wireless
set 0 disabled=no l2mtu=2290 mode=ap-bridge ssid=test6 wireless-protocol=802.11

Thanks for all.

You need to bridge ether5 and the wireless interface. Then move the ip from ether5 to the bridge.

Restore the factory default settings and look at that config. It will give you a good idea what to do and you could probably just use it and have no problems.

It's working "almost" fine:

Here is a configuration that working fine (wifi no secure: no authentication - no cipher - with XP SP3): XP can ping mikrotik:

[admin@MikroTik] > export compact

jan/02/1970 00:29:03 by RouterOS 5.14

software id = 2AYL-KERF

/interface bridge
add admin-mac=D4:CA:6D:29:CE:CD auto-mac=no name=bridge-local protocol-mode=rstp
/interface wireless
set 0 disabled=no l2mtu=2290 mode=ap-bridge ssid=test6 wireless-protocol=802.11
/interface ethernet
set 0 name=ether1-gateway
set 1 name=ether2-master-local
set 2 master-port=ether2-master-local name=ether3-slave-local
set 3 master-port=ether2-master-local name=ether4-slave-local
set 4 master-port=ether2-master-local name=ether5-slave-local
/interface wireless security-profiles
set [ find default=yes ] eap-methods=passthrough
/interface bridge port
add interface=ether2-master-local
add bridge=bridge-local interface=wlan1
/ip address
add address=192.168.88.1/24 interface=bridge-local

Here is a configuration that don't work (wifi a little secure: no authentication, cipher WEP key - with XP SP3): the only difference is

/interface wireless security-profiles
set [ find default=yes ] eap-methods=passthrough

becomes

/interface wireless security-profiles
set [ find default=yes ] eap-methods=passthrough mode=static-keys-required static-algo-1=40bit-wep static-key-1=0000000000
static-transmit-key=key-1

If on XP I try third solution:

  • authentication: WEP Key,
  • cipeh WEP key (as below)
    the wifi network can't connect to mikrotik. Is it normal ?

But this is not a problem, I won't use WEP Key.

So, all my problems comes from bridge. Now, I've understood.

Thanks for all.

Best regards.

Why do you want to use WEP and not WPA or WPA2?

mikrotik is new for me. It seems to be a good product.

The goal is to use Radius Server with Win 2008 (DC) and Seven.

But it will be difficult i think.

So I begin the most simple as possible. WEP is simple.

Now, WEP work “quite” fine.
I’ll go to configure mikrotik to use Radius Server with 2003 (DC) and XP (I know how to do with a D-Link AP). When it will work, i’ll try with 2008-Seven.

Possibly: is it possible to have “authentication WEP key” and “cipher WEP key” with an XP SP3 ? How to configure mikrotik ?

Thanks for all.

Best regards.
