i'm having the same problem with netduino plus 1! !

Hello guys!

I'm trying to execute a sample of netduino webserver ,but i'm getting the following 

error :  Ocurred one untreated exception of the type 'System.Exception' in Microsoft.SPOT.Net.dll

When i execute the following method : NetworkInterface.GetAllNetworkInterfaces()[0];

I already tried with another code posted here in the forums.

I attached a print of the error and the code . Any ideas of whats happening ? 

Thanks in advance!

I'm having the same problem!!

So if you print out the [0] result of GetAllNeworkInterfaces() you would see NULL.

 

I find this interesting because I just bought a tplink tl-wr702n and see exactly the same problems with my NP1.  Of course it works just fine with my laptop :-).

 

I found one forum post that said the tplink wotks with the NP2 but not the NP1.  I'm going to do some more research, I'll let you know if I figure out anything.

 

What did you change in the router to get the lights on?

Hello John! interesting !! I didnt know about it ...i'll be searching and looking for an answer too!

Well , about the settings in the router ... nothing special

1. Enabled DHCP

2. Reserved one IP between the DHCPs IPs range ( mine was 192.168.0.198)

3. In the MFDeploy , i changed the gateway's IP ( i took it via cmd ) (usually its 192.168.0.1)

4. In the MFDeploy , i changed the netduino's IP to the IP i reserved in the router (192.168.0.198)

5. In the MFDeploy, i  checked the DHCP as enabled

When i ran the code the IP showed was 0.0.0.0

I got no entry in the DHCP client list ... thats pretty weird , because apparently i still got no connection but the lights are on now

Please keep me updated  John

Many thanks and if i can help you just let me know!

[UPDATE] Changing the router settings the ethernet lights now are turning on . But , when i'm  compiling the code, a  'System.Exception' in Microsoft.SPOT.Net.dll is showed when i call this method : 

Microsoft.SPOT.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()[0].EnableDhcp();

[UPDATE] I've just flashed the firmware and updated it to the v4.2 and still nothing

[UPDATE] I noticed that when i disable DHCP in the router all the devices connected by cable lost the connection (internet and network)

Many thanks Zoot! i'll keep trying the possibilities you pointed out .... but , for now , to make the things easier , i just bought a netduino plus 1. Again , many thanks

Hello Guys !! i'm a happy owner of a Netduino plus 1 device and i'm trying to do my first simple netduino web server.But, when i connect the ethernet cable to the netduino device no ethernet lights are turned on. I've already tried :

1. Reinstall microframework and netduino sdk

2. Verify if its a ethernet cable or usb cable problem (it isn't , both are working as expected)

3. Changed the default gateway in the MFDeploy to 192.168.0.1

4. In the router (tp link tl-wr740n),i disabled DHCP and nothing (same with DHCP enabled)

5. In the router , i reserved an adress to netduino (using its mac adress)

6. In the router , i observed the DHCP client list to see if i got any entry  (and i got nothing)

7. Reseted my router

8. tried to ping the netduino  and i got no responses

When netduino is connected to the router the default IP is showed.But when i connect it to the internet cable, another IP is showed (192.168.1.2) and the ethernet lights do turn on

Everything leads me to believe that i'm missing some configuration in my router.

Here is the device capabilities :

Thanks in advance
