Web Server: The code auto-negotiation fails with a router?

Again, There are 2 different projects:

1) My own design on my own board

2) Altera Development DEMO Board (CycloneIII 3c35 kit-80) - with display screen and all...

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

The below are used for both the projects:

1) Router: N150 Wireless Router Model WNR10000v3

2) Switch: Netgear 10/100/1000M Switch GS605 v2

3) Hub: Dynex Model#DX-EHB4 10BASE-T Ethernet Hub

Note:

When I connect my old laptop to the above router, it says "LAN is now connected Speed:100Mbps"

When I connect my old laptop to the above Hub, it says "LAN is now connected Speed:10Mbps"

When I connect my old laptop to the above Switch, it says "LAN is now connected Speed:100Mbps"

1) Project 1: My own design

PHY: DP83848C 10/100 Mb/s Ethernet Physical Layer Transceiver

2) Project 2: Altera Development DEMO Board (CycloneIII 3c35 kit-80)

PHY: 10/100/1000 Ethernet

QUESTIONS:

1) Project 1: My own design

Now the question is, if the laptop can connect to the router and say "LAN is now connected Speed:100Mbps", what could be the possible reason that my PHY (DP83848C) doesn't Auto-negotiation ?

Note: The PHY successfully negotiates with hub and switch, but not with router or laptop.

(Just FYI: I am using the Web server design example for this project. DHCP is enabled. The Default ip I have used in my source code (@web_server.h) is 192.168.10.234 [GWadd: 192.168.10.1] [MSKADD: 255.255.255.0])

2) Project 2: Altera Development DEMO Board (CycloneIII 3c35 kit-80)

With Router. the DEMO board seems to get ip 0.0.0.0. This happens 9 out of 10 try's. (I am checking router page to check the mac adds connected to the router. All those 9 times, it doesn't shows the DEMO Board connected to router). I was able to successfully get an ip (192.168.1.2) just once. And the WebServer_HTML was opened successfully.

Is there some sequence I need to follow when I use the DEMO board, so that it acquires an ip for accessing the WebServer_HTML ( Altera Web Server)?

What about connection the DEMO board to laptop, or Ethernet hub or Ethernet switch?

Would I never be able to connect the DEMO board using either of them and access WebServer_HTML page?

(Just FYI: The source code for the DEMO board is not available and the default ip address in their source code just be 0.0.0.0; Netmask:255.0.0.0; Gateway:0.0.0.0;

This is what shows on Web Server Info on the display screen of the DEMO board after acquiring 0.0.0.0 ip)
