# Firmware version 1.1.1 and IE11

## Question

Asked by DaveOLW on 2015-09-19 in General.

The new Firmware Version still does not work correctly in IE11.

With this new version 1.1.1 which it said it sorted the problem out in Internet Explorer 11, but it does not.

```
  "•Bug fixed: Socket and data length handling problems in some web browsers (e.g., ie11)
   •Modified the TCP socket state transition handler of the HTTP server routine for clarity"
```

Although now it does now change Led’s and relays the Page is not updated, so after changing one “ON” it will not allow you to set it “OFF”.

Thanks.
