Changing MR3020 to a fixed IP

Post by NormanW »

It's been another frustrating day!

I use a TP Link MR3020, flashed with meteobridge to upload data from my IROX Pro X to Wunderground etc.

For the last three months, I have had problems with the MR3020 stopping sending data. Usually pressing the left button once re sets it. However today it went back to a previous error where it just will not connect to my wireless LAN.

The internet router and the MR3020 are on a dedicated UPS, which when we lost power for more than 2 hours last week, worked flawlessly to keep the systems on line. Regular power outages were what I thought was causing the problems, but apparently not.

The MR3020 stopped reporting at 03:15 this morning. Nothing else stopped and I have no error log or way of finding what the cause is.

I have spent most of the day trying to get the MR3020 back on line, which I have now done using a LAN cable rather than WiFi. Quite a length of time has been spent in trying to find the dynamic IP that DCHP has allocated, then accessing it. I cannot get it to access the LAN over WiFi

What I am wondering is whether changing the address from Dynamic to fixed would make any difference to the operation. Has anyone any experience of using fixed IP's?

Both the internet router and the MR3020 are in the same room, so signal stength is not the issue. There is obviously something else, but I don't have the knowledge to trouble shoot it.

Basically I use fixed IP's for just about everything give or take the odd device where it really doesn't matter. The MB's, MBPro's, IP loggers etc all have fixed IP's in conjunction with the overall network design. Just needs to be structured with a logical layout/design that can be understood and easily managed. In remote configs behind routers with port forwarding then fixed IP's are the only way.

I only use WiFi (as such) for the main backbone running Ubiquiti, switch to switch and then cabled wherever I can. I don't run any of the MB/MBPro's wirelessly, which is just the way I do things.

Most routers have a DHCP IP list of what device is connected. That is the easiest way of determining what IP has been issued.

I started off using a wired connection and a dynamic IP without any problems. Last week I switched to a static IP. I have not used wireless as the routers are beside each other. If possible wired is always a better choice.
Be sure to select an IP that is not within the DHCP range of IP's otherwise you might end up with a conflict if the router assigns the same IP to a second device. This is normally seen under the LAN tab as a starting and ending pool of IP's. Pick an IP under 254 that is not within the pool.

When you go static with your IP, then you need to give IP, mask, gateways and DNS absolutely correct. One error there and it will not work. So I don't recommend static IP for the novice. Compromise is to tell your router to give it a fixed IP based on the MAC but to keep the client at DHCP, this is best of both worlds imho.

When your browser is in the same LAN as the Meteobridge, finding IP is most easy by calling "http://magicip.meteobridge.com" which will redirect your browser to the current IP of your Meteobridge. It can't be more easy.

One last question. Are you using the mandatory USB hub to drive your weather station? If not, drop offs are caused on the USB connection, not the LAN/WiFi side.
