Topic: Genuine Arduino WIFi board returns "no wifi client"... ? (Read 2155 times) previous topic - next topic

Not only could I not really get my Ethernet shield to work reliably, but I have now received a boxed, genuine Arduino WiFi shield, but on running any WiFi Sketch, I simply get the message "No WiFi Client"

I have read through this forum and have not really found any info, other than lots of mentions of the WIFI101 library, which I have downloaded and tried, but that gives many errors.

I assume that my board should use the original WIFI.H library ?

Any ideas would be very welcome, I am getting somewhat disenchanted with these shields so far.  2 out of 2 failures ain't very good.


are you referring to this product?

can you detail more this "but that gives many errors"
which board is under the shield?

have you tried with latest 1.6.11 IDE + WiFi101 library?


Sorry if the info I  gave was a little lacking.

The board I have is NOT the one you list, but it came in a genuine Arduijno box from Italy, and has a sticker on the top surface that says :


I  do not  know what that means, but as usual there was no documentation worth having in the package other than the much folded up Arduino advertising slip.

It is running on a standard Uno ( I have tried 3 different Uno boards) When code is loaded, the boards LED's flicker, if I press the reset on the shield I get a brief RX flash, and after quite a delay, another "WiFi shield not present" in the monitor window.

The same Uno boards have worked with an Ethernet Shield from the same source.

I am using the 1.7.10 Arduino programming interface, so the very latest I would guess, as it is what is  on the arduino.cc site right now. ?

I tried loading the "wifi101.h" file as well, but that gave errors in one of the original .cpp files ?

I do not know what else I can tell you, I have a working WiFi router in my BT hub 5 and those settings for user/password are entered into the example WiFiChatServer sketch.

The line in the sketch to connect the server is set to port 23 - (the standard telnet port), but almost the next line :

if (WiFi.status() == WL_NO_SHIELD) {
    Serial.println("WiFi shield not present");

Is what I get - every time.

Help please ?
