I have D-Link DSL-2640U router. I tried to update its firmware (using google chrome) using the wireless connection. But after uploading the file, the router showed a message telling that upload FAILED!!! Now I can't access the router totally. The default IP was 192.168.1.1. I tried RESET button but no benefit too.

Wireless Interface

You are able to quickly create a wireless network at home or in your office, which lets your relatives or employees connect to your wireless network virtually anywhere (within the operational range of your wireless network). The router can operate as a base station for connecting wireless devices of the standards 802.11b, 802.11g, and 802.11n.

The router supports multiple functions for the wireless interface: several security standards (WEP, WPA/WPA2), MAC address filtering, and the WPS function.

In addition, the device is equipped with a button for switching the Wi-Fi network off/on. If needed, for example, when you leave home, you can easily switch the router’s WLAN by pressing the button, and devices connected to the LAN ports of the router will stay online.
