Hello to all

I’m using RB450g for my Hotspot and user manager, I’m using v5.22, In log it shows dhcp error… “default failed to give out IP address:pool is empty”. Wireless client could not log-in. How to solve this problem. Thanks and more power.

Looks like in the you haven’t specified any pool of IP addresses to give out at the customers in the hotspot server.
You should post some config of your hotspot, so one can check it better.
Have a look at the Hotspot server in address pool if there is any pool assigned there. Also look at the /ip pool if the one specified in hotspot server is there and what addresses it is giving out.

You have run out of addresses in the pool. Either extend the pool, shorten the lease time or add additional pools (plus other implied config changes).

well spotted @CelticComms

I’m just a noob sir, how to extend the pool?

For me the best option would be not to increase the pool, unless you are planning to give service at more than 244 customers, but rather shorten the lease time.
The default lease time for the dhcp-server is 3 days, which means that if a customer connects for 5 min for example, the dhcp server will keep its record for three days. This means that the Ip assigned to this customer can not be used for other 3 days. So you can bring the lease time down to 12 hours for example. You can do that at the dhcp-server config.
