R310 IP Conflict with Windows Desktop

[jiaming_lau]

Both R310 and Windows Desktop are directed connected to the ISP Router. However, we are facing daily network failures due to "conflict of ip".

We set a static ip for our R310 and excluded the ip from the DHCP pool. It went well for about a week after which the same issue occurred again.

This is happening in my customer's shop and there is no way they could wait for us to arrive to troubleshoot when the internet is down as they require the internet to process payment.

Are there any troubleshooting tips for this issue?

Hi all,

The IP conflict issue has been resolved.

We have reserved both IPs 192.168.1.253 and 192.168.1.252 to the AP and desktop respectively. 1.254 remains as the default gateway.

However, we are still facing intermittent downtime of the internet. We would then have to either restart the router or we have to unplug the R310. The former will result to a similar downtime after a few hours and the latter will resolve the issue.

Would like to check if it is still a DHCP issue?

Please advise.

Thank you.

It sounds like you need a different router there. This smells like the arp table is getting full, or the MAC learning is having a similar issue. We had an issue with a switch (router really) that would not flush the MAC table. The switch would learn every MAC of every device that drove by our building and then would stop forwarding, since it could not maintain its MAC table.
I would blame it on either a bad router or bad firmware. Maybe you want to re-flash it.
