Internet Problem Question

<p>Last week my internet went out, had like a power surge and it messed up the modem and the wireless box. All the laptops now work and can get online, but I can't get my desk top to connect to the internet. I log onto T-online and it does all the steps until the last one and comes up and says TCP/IP error 735. Does anyone know what this means or even better how to fix it? </p>
