# W5100 usage.

## Question

Asked by muralysunam on 2017-12-02 in Ethernet Chips.

Hi all,

I am using w5100 with Arduino ethernet shield. I would like to know whether this can be used to connect to internet from a DSL(BSNL RJ10 Socket)? I would like to dial from microcontroller.

Thanks a lot.

No, but you can use DSL modem to connect to DSL line, and connect W5100 to this modem, as a bonus you will get modem’s internal router with DHCP capability and local DNS services.

Thanks for quick reply. Is there any way to interface with ADSL lines(DSL). I just want to dial and get the error code (normally modem will be configured as bridge mode). I just don’t want to buy a modem for this bridge mode operation. Any other suggestions? Thanks once again for help.
