Topic: can't reconnect GW1000 to wifi

[Shvedi]

Last night my GW1000 disconnected from my home wifi network. I've tried many times to reconnect it to the network, but no luck so far.
The WS View app finds the device, but always tells me that is can't connect. I disabled the cellular data, entered the right wifi id name and password, reset the device to factory settings - but every time I get the same result.
I tried to reconnect by using the GW1000 Wi-Fi Configuration with PC Software, it connects to the home wifi network (the red light flashes slowly), but it doesn't show up in the WS View app, so I can't see the data on the app or website.
The app version is V1.5.3.
What more can I do to reconnect my GW1000 to my wifi?

Check your date and time in the router.
Reset the router.

I performed a router reset several times. All other devices (laptop, some mobile phones AND my Ambient ws-2902) are connected without any issue. The ws-2902 reports to ambientweather.net and weathercloud constantly. The only problem is with GW1000.
Just before it happend, I connected wh31 and wh41, and they both worked fine with GW1000 and ecowitt.net.
But now nothing is reporting because of the lack to reconnect the GW1000.
According to the manual - the wifi (red) led indicator:
"Flash (slow), indicates connected to Wi-Fi network; network communication normal, but upload to one or more configured weather services failed. First confirm Internet access through your router is functioning, and then check whether the upload server account and password are correct (use WS View application)."
But I can't upload to ecowitt.net if the app doesn't see the GW1000.

Where is the GW1000 in relation to the WiFi router? Perhaps you have it in a place where it can't get a good WiFi signal. The GW1000 doesn't have a display therefore it can be anywhere. What are you using to power it via USB? Is it being provided constant power because some computers when they go to sleep they disable the USB power. I recommend a USB power plug and not a computer for power. Having a USB power plug allows you to move the GW1000 to different places to get better WiFi.

[Shvedi]

The GW1000 is plugged to a cell phone charger, not to a computer. For the registration process it seats in the same room of the router, but before v1.5.3 it had no connecting problem at it's permanent place.

[galfert]

Why does it need to be moved from the registration place next to the router to other "permanent place"? Why can't it stay near the router? Because it seems to me like whatever you have chosen as a permanent place is a weak WiFi area. I understand that prior to 1.5.3 WiFi performance was better. The objective now should be to find what works now. Then you can report your findings and what you had to do to make it work and see if the next firmware update makes an improvement.

Just a minor thought but are you using 2.4Ghz or 5Ghz?
If you have both and the GW-1000 is using the 2.4 band and your mob is connected via 5Ghz its possible that the router is not passing the broadcast traffic between the wifi bands.

Also for setup purposes you would defo need to be on the same 2.4ghz band. Initial setup the GW-1000 is its own hotspot on 2.4Ghz so if you cannot see that then its your mob that is having the problem.
Once configured the GW-1000 obviously then hooks into your 2.4Ghz Wifi network and connectivity is via broadcast to find the gadget from your mob and the app.
At this point if the app cannot see the GW-1000 then its because it is not seeing the broadcast packets from the GW-1000.
These broadcasts are not every second they seem to be around 30 seconds so it can take a moment for the GW-1000 to appear. This is normal.

[Shvedi]

Only 2.4Ghz

OK, another thought, have you fixed your IP address for the GW-1000 on your router
Most routers will allow you to fix the IP address (make it static)

I have seen an issue where the IP address (DHCP lease) changed but the GW-1000 did not seem to understand that and it screwed up connectivity.
It will be still connected to your Wifi but not have any network connectivity which sounds suspiciously like your problem
I had to go back to basics (reset the GW-1000) and then fix the IP address on the router. After that no problem.

[Shvedi]

No, I've never fixed the GW1000 id on my router. I don't think I know how to do this, and anyway I don't need it.
As I wrote, I reset the GW1000 multiple times. Nothing has changed in the router. It must be something connected to the device or the firmware.
If I try to connect the device to my wifi network with the app, my phone recognize the GW1000 ap, but can not make a connection - it trys to connect, fail and says " IP Configuration Failure". It was like that since I received the device,
and the only way I could connect was using the GW1000 Wi-Fi Configuration with PC Software.
But it worked, and my GW1000 was connected. I could see the ws-2902 data, as well is the GW1000 data, and also the WH31 and WH41.
Last night the device lost connection, so I reconnected it trough the PC, and all I can get is a slow flashing red led.
When I open the device list in the WS View app, the only device I can see is my Ambient weather station, with it's correct mac address (but can't open it) - and no GW1000 in that list.

I have to say that everything you have written suggests that the DHCP lease (TCP/IP address) has changed on the router and the GW-1000 has not updated and so you lose network connectivity at the TCP/IP level.
The GW-1000 is still connected to your WiFi but just cannot talk.
The fact that all was good for a day and then broke backs this theory up.

If you login to your router and look at LAN settings you should find a section for DHCP.
There you should be able to find what the IP address is and fix it.

In order for this to work I recommend that you do the GW-1000 reset first and reregister it to your Wifi and then find its TCP/Ip address and then go into your Router settings and fix the address.
I believe that this will resolve your problems.

I have to say that everything you have written suggests that the DHCP lease (TCP/IP address) has changed on the router and the GW-1000 has not updated and so you lose network connectivity at the TCP/IP level.

Is it possible that the TCP/IP address has changed only for the GW1000?
My WS-2902 connetion to the router has not changed - I can see the data, console and websites.
And - if indeed the TCP/IP address has changed for the GW1000 - wouldn't a reset of the device to factory settings (which I did more than once) should fix it (the router can't "know" it's the same device, can it?)

[Mandrake]

The device is recognised by something called a MAC hardware address. This is unique for all hardware devices that have a network connection.
The router should recognize the device and issue the TCP/IP address and keep that allocated as long as the device does not reboot.
If the device is rebooted it uses something called DHCP protocol to request an TCP/IP address and then the router will issue an address. If you have not told the router to always issue the same address (fixed/static) then the router may well issue a new address.
The GW-1000 should at this point recognise its address has changed and all should be good, but some devices (possibly the GW-1000) do not seem to handle this well and the DHCP process does not quite work properly. The end result is that the GW-1000 still thinks it is using its old TCP/IP address while the router thinks its issued a different address via DHCP and the GW-1000 stops working.

This should not happen in an ideal world but sadly I have seen this happen on many devices and cause problems.
Anyhow, I guess the point I am making is if you fix the address via the router after you have setup the GW-1000 this will avoid the risk and will probably resolve your problem.
If it does not solve the issue you wont have broken anything but will have eliminated this 'known' type of issue.

[galfert]

I wonder if there is a double NAT situation with two WiFi AP on each subnet and they both are set to use the same WiFi credentials? Or maybe even worse, two DHCP servers on the same subnet.

If you don't know what any of that means then tell us about all the networking stuff you have.....modem, routers, mesh nodes, WiFi extenders....etc.

[Shvedi]

I solve the problem.
Apparently when you connect the GW1000 to your home network, you should first turn you router off. Than you power up the GW1000, connect your phone to the device's AP, and only after it connects - you can turn on the router and continue the process with the app.

I have played with my GW-1000 for a month now and its not turning out to be the end all. I thought that I would replace my old Observer IP with it given the good review about its connection stability. I run an ASUS AImesh all over my house with great connectivity. The GW connects using android app, gets setup with all the services and a day later its not transmitting. It has an assigned fixed IP from DHCP. I have the same problem as the original poster, in that running the new device setup goes nowhere. It says its connected and then nothing. My WU subscription still shows up but does nothing. In total frustration, I uninstalled the Android App and reinstalled it hoping to get a fresh start. After many attempts, I got it displaying my array with the correct MAC and IP. A few hours later, it is off the air again.
I went back to my Observer IP and am shelving my GW until it matures some more. My Observer did "fall out" many times during the 5 years I have owned it but nothing like this.

Very strange, sounds like your GW-1000 is having some connectivity issues with your wifi setup.
I recall in its early days there was discussion around channel setup (widths). Could be something like that.
Do you have a spare router/AP you could play with to test?
I say all this as the GW-1000 really has been solid for me since the initial very teething troubles when it was launched.
