Bad wifi connection duet2wifi
-
So this is a derived post from another topic. I recently suddenly got some connection issues with my duet2wifi. Since a few weeks it suddenly got a hard time connecting and staying connected to the wifi. The only thing changed in that time is a aluminum plate between it and the wifi but I have now placed a wifi repeater next to the duet so that is solved. The problem is that the wifi module takes a long time to first connect to my wifi. When it is connected the webcontrol often gets interrupted, it also gives this message then. Also things like sending commands have a delay and the icons not always load well.
Things I tried to solve it:
- wifi repeater next to duet. dbm is better now around 50, was around 70 before but didn't solve it.
- update firmware, wifi firmware and webcontrol to newest.
- Add antenna to wifi module.
Sadly nothing seems to work as of now. This happened with now real cause. Is my module maybe broken? The led keeps on shining on the module when it is connected.

@bierent did you delete your previous WiFi information? It may be battling between the two to connect

@jay_s_uk
What do you mean with previous wifi information? The .bin file? -
@bierent no, the saved WiFi from your original access point

@jay_s_uk
It has the same ssid and password as all the other ap's in house. I hope the duet picks the best one. Would it maybe work if i use a different name on this ap, specifically used for the duet? I think the duet is than still accessible via the whole home network. -
@bierent yes, that may be a good idea. It may be having issues with which to use

Have you tried replacing the SD card? You can copy the contents of the current card straight across to the new card.

Changing the SD card did nothing. Changing wifi ssid did make the duet connect faster to the wifi (looking at the blue LED). But the webcontrol still gets interrupted and is slow. The dbm is also still 64 while the extender almost is next to the duet. My phone gets like 35dbm on the same spot. -
@bierent looks like that aluminium plate is really screwing with the signal.
if you have the tools you could swap the ESP for an ESP07 to give you an external antenna -
@jay_s_uk
That's the thing right now, the wifi repeater stands almost next to the duet. Now there is no aluminum between them.I dont have a hot air solder station or ever worked with it but if that is the only solution I will need to do it. Is it also possible to solder an ethernet module or something to it? A normal solder is something I do have.
Don't mind the wires, it is still a work in progress.

@bierent you can also be too close sometimes which could cause issues. Make sure your repeater also isn't broadcasting on 5GHz
You can remove the wifi module altogether and install a duet ethernet module but again this really requires a hot air station.
If you're in the UK, I can do either -
@jay_s_uk
It only sends out 2.4ghz. A little distance makes no difference. Sadly I live in the Netherlands so if I send it I'm afraid it could be gone weeks with the transportation.Just a simple hot air station which are used for smd works okay? Than I will learn how to do it. And would you recommend an ESP07 to replace it? I can't find the ethernet modules at the official duet sellers in my country so if the 07 is a better module I am willing to try that one. Furthermore are all the connections just the same? I can just replace it without rewiring some stuff?
-
@bierent yep. its a straight swap. they're what i fit whenever i'm repairing a wifi board that needs a new module.
I also use a heated plate but you may be able to get away with just a hotair station for SMD's -
@jay_s_uk
Okay than I will look for the materials coming week and hope it works
.
Thank you for your help!
