WAP200 and entry for primary dns cannot be 0 and 255

I have a wap200 with a static ipaddress e.g. (it is for management and is in vlan 1). Firmware of the wap is No gw and no dns. (they are not necessary) I export the config . I have a second wap200 and import the config.bin to the new wap. ThenI like to change the static address and the name of the new wap, but - and this is the problem - it asks me to fill out the dns (the address for primary dns cannot be 0 and 255), but I absolutely don't want that because there is no dns or gw (management only). And if I fill it out I cannot go the the internet with the wap.

So I also have some other wap200 where I could import the config.bin and change the static ip without giving a dns (firmware

So my question is: can I go back to a previous firmware (Europe) and where can I find it. Looked for it, but seeing only the last one etsi.

Or is there another method to skip the dns with a static ipaddress?

many many thanks in advance.



Is there no one with a solution? Old firmware?

Hi Kurt -- Thanks for participating in the Community. Please contact me directly (streaves at cisco dot com) regarding the previous firmware version.

Goodmorning Stephanie,

First a great thanks for replying to my question.

For explaining my situation I ‘ll try to give you a full view.

I have 3 vlans configured on the network through a Motorola wireless ws5100 switch . Vlan 1 ( management, vlan 2 ( for the public, vlan 3( for internal users only.

I have 4 wap200 configured of which one is having trouble. I configured the other three as follow: starting, connecting, giving it an ipaddress in the management vlan and upgraded the firmware from version 2.0.1 to 2.0.4. When I connect to the wireless ssid “public” I get an ipaddress from the range 172.20.176.x. When I connect to the ssid “internal users” I get an ip from the range 10.63.128.x and when I connect to the ssid “management” I get an ip from the range 192.168.249.x. The last one is only for management so I can not go to the internet from here (which is ok), from the other two I can go to the internet as wished and the two ssid’s can not communicate which each other as wished.

Important: the ipaddress of the wap200 has an ipaddress with no dns input (no dns is needed so..)

With the fourth one I did first a firmware upgrade and I imported the config of another wap200 (one of the first three). Then I wanted to reconfigure the wap (ipaddress) but when I change the ipaddress and click on save I have to give also a dnsentry. (When I do this with the other wap200 it’s asking me also a dnsentry, so it must be the firmware). When I give a dns entry I cannot go to the internet with ssid “public” nor “internal user”.

So what I thought is to go back to firmware 2.0.1 and then import the config of another wap200. So I can change the ipaddress without the need of a dnsentry. After that I can upgrade to the last firmware. And job done.

Hope you can help me to make the situation usable.

Kind regards
