Convert existing LAN to Wireless network? Please Help. Urgent.?

[ajlokras]

I have a LAN setup in my laboratory through a switch (8 port). The main connection from ISP is PPPoE. However, when I connect my laptop to the LAN, I need to input settings as follows (WORKING INTERNET VIA LAN CABLE TO LAPTOP):

IP Address: 10.10.0.1xx
Subnet mask: 255.255.254.0
Gateway: 10.10.0.1
Primary DNS: 10.10.0.1

The internet works only with above settings and DHCP results in connection but no browsing, internet, etc.

I cannot disturb any of the setup but I do want to convert that into WiFi zone. I tried setting up my Wi-Fi router (Dlink DIR-605L) as an Access Point.

Router IP: 192.168.0.1
Subnet Mask: 255.255.255.0

Disabled DHCP server.
I connected the LAN cable from LAN Switch to WiFi router's LAN port (not WAN). Still I do not get internet connectivity. Please help me what to do.

Also, "I TRIED" setting the wifi router as
Router IP: 192.168.0.1
Subnet : 255.255.254.0
Gateway: 10.10.0.1
DNS: 10.10.0.1. It is saying IP Address must be within the LAN subset.

Can anyone please let me know the exact settings to put and where along with the values? I've been trying to look online and failed miserably since the past few days.

Update: PPPoE is not a concern as the settings are already fed. I just want to make the 8 Port switch convert to Wireless signal by this Wi-Fi router (As an Access Point)

Fun little router, and first try to plug the ethernet into the modem port on the back (the yellow one on this particular router). Not knowing if you've tweaked advanced router settings you could do a hard reset if you wanted as well. Connect to the router with your laptop and go to cmd. (The only reason for this step is because some routers detect network infrastructure and automatically change default ip to 10's instead of 192.168.x.x...) In command prompt type ipconfig and look for your default gateway. Punch the default gateway into your web browser and pull up the web interface for your router. Personally not knowing the interface for your router you will have to look through the settings for PPPoE. The setting should be there somewhere. The label might be "advanced" or "internet connectivity" for example. I assume this is what you were saying when you said you "tried setting the router to etc etc etc" But putting the configuration inside the router should work.

I am by no means a Wireless settings expert... just for what it's worth sharing how my set-up is hooked up to possibly point you in a direction that could help.
I'm just wondering have you tried feeding the connection from your wired hub through the WAN port of your WiFi as kjhmario stated and rebooting all devices when they are connected this way. I currently run a Wifi Extender Hub which is wired to my home routers wireless which has WiFi enabled but also has trouble reaching the back of the house let alone the back yard. From the extender Hub I have a wired connection running a smaller wireless router providing much needed signal to the rear of my house and the backyard.
The setup I run is as follows

I never had to reconfigure or clone IP address subnet mask or anything. My home ISP router is 10.0.0.X but my Netgear is 192.168.0.x each running their own separate access point name and settings.
It does not see anything connected to the Netgear as being accessible on my home network for Homegroup file sharing or anything of the sort... I presume if I were to clone the IP to the 10.0.0.x And set Sub net mask DNS suffix and so forth it would enable this. As well as not having to setup multiple access point names and passwords... but all in all this serves my needs flawlessly as anything I access my internet with in either place connects as needed to the more preferred connection automatically.
I have DHCP enabled on the Home ISP router and believe this is what allows this to function as it does? But I am no expert when it comes to most of these settings... until there is a problem for me to troubleshoot and as yet it has not been an issue for me.
So other then sharing how my internet is connected and works with each other I probably wouldn't be able to point you in the best technical direction to further troubleshoot this issue... But I would list specifically the Model of *-port Hub you are using as in the past I had a friend who had a Cisco switching hub that would not carry a signal over to any other hubs, wireless or otherwise, connected to it though it would support all computer connections... something due to it's firmware I believe?
I could just be lucky and have the kind of internet gear that plays nicely with each other... then again you could be lucky enough not too.

Not that this is the ultimate answer before you do all the research needed, but a few cheaply acquired choice pieces of internet hardware off fleaBay might be in order in this case.

Hope you can get this going if you haven't already.
