MikroTik

Hi,

I use Mikrotik CRS109-8G-1S-2Hnd as wireless access point. It has a WAN connection.

Problem is mac book connects to Mikrotik wireless network but has no internet access. I can fix this problem by logging into the Mikrotik administration page, select Wireless -> Registration -> Click on the connection -> Ping. After that there is a working internet connection. I have the same issue with Microsoft surface pro 4.

I have latest Samsung phones, and ereaders which can connect to the Mikrotik and have internet access immediately.

I configured the Mikrotik wireless network through the administration interface using Quick Set.

Thanks for any help.

Hi ziltoid, please post your config to help you. To do this, open winbox, access to your router, open new terminal and write this:

What security profile are you implementing on the wireless, is it wpa or wpa2. Is it a hotspot billing. If clients are connected and they are not browsing can you check that the dns on your dhcp server is correct and also the IP address that is on the client is also correct. please send screen shots.

Thanks a lot for the replies.

ekpesinyang, I will check the clients settings when this problem occurs and will paste the results.

Sorry for the late reply.

ekpesinyang, this is the network settings.

This issue is resolved.

The devices arp tables had the wrong MAC address. There was another device on the network with the same IP address as the gateway.
