Once I changed network from home to work on my laptop, hostnames worked.

<div>
Great! &nbsp;Happy to help.

<div>
<div class="content wysiwyg-content">
I have a ATT UVERSE router, and a TP-Link TL-WA801ND access point connected to it. &nbsp;<br />
<br />
I have a server 2008 running behind the ATT UVERSE LAN with a static IP. &nbsp;When my laptop is &nbsp;connected to the ATT UVERsE over wifi I can ping the server by IP and hostname. &nbsp;<br />
<br />
When I am connected behind the TP-Link I can ping by IP, but not hostname. I need to be able to connect by hostname, because of the database I am using....<br />
<br />
The funny thing is that it worked before, and now it doesn't. &nbsp;I tried resetting the AP to factory default, and setup again, but it still doesnt work.<br />
<br />
Any ideas?

Can't Ping by Hostname

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries, organized in abstraction layers, traditionally called "Link," "Internet," "Transport" and "Application”. Its routing function enables internetworking, and essentially establishes the Internet. IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information.

Internet Protocols

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.

Wireless Networking

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
