DHCP Server - Different Range for Wired and Wireless Network

We have DHCP setup on Windows Server 2012r2 and the range given to us by the main HQ is 10.65.112.1-10.65.112.254 (there are several exclusions under this range)
Now since the range gets exhausted quickly, they provided another one 10.65.122.1-10.65.122.254.
What our branch would love to do is to dedicate the first range for Wired Computers and the other range for Wireless Devices (Phone,Tablets, Mobiles)
Right now we have 2 different scopes setup in DHCP, the second one is disabled. In our network we have 6 access points and also have a CISCO SG300-52 Managed Switch. It has an inbuilt DHCP Server and also has the function for DHCP Relay. But we are not actually using any of its functionality as of now.
So my question is how to have 2 separate ranges for wired and wireless network. People have mentioned vlans but I have no clue on how to get that done.
Is there a simpler way avoding V-LANS or if not, would love to get step by step procedure on how to go about this. Any help will be much appreciated
Regards,
Sheldon

Hi Sheldon, please read this post

You will need some modifications though. Steps 1-6 is very relevant. On step 6, you need to pay particular close attention to the "default router". If the SX300 handles your intervlan routing then the default router needs to be the IP of your VLAN. If you have a different device to handle VLAN routing then the default router needs to be that IP address.

How to control bandwidth for wired and wireless

I have a wrtn400n dual band router and I was wondering if there is a way from the router settings that can lower internet connection for wired and wireless. Reason why its because I have 3 cousins that ALWAYS downloading music, videos, or watching a movie from an asian website. It lags me so much, that I can not even play online games. My ISP is comcast which is cable. I can barely surf on the net. Its like, they're taking up all my connection. I know there is a way to do it without cutting them off from the connection. It's a 2.4 and a 5.4ghz router and I can't find my 5.4ghz ssid on my wireless networking thing. My sister and I are wired connected while my cousins are wireless, but sometimes one of my cousins wire their laptop. The modem and router is connected to my computer. Please help me!!! I know theres a way to do this, but I just can't find out how!

Officejet Pro L7780 Wired and wireless networking at same time

I have an officejet pro L7780 printer that I would like to use wired and wireless networking at the same time. It that possible. The printer is connected directly to the network by ethernet, but I would like to print wirelessly with an ipad or iphone using HP ePrint Home and Biz.
Thanks,
Maurice Hawley

The bad news: no it is not possible to have two connections active on your printer at once.
The good news: the router will connect any device to the printer regardless of how the printer or the devices are connected. So your iPad can print to a printer that is wired (with Ethernet) to your router.
If it does not work, restart your router by pulling its power plug momentarily.

NAC Guest server for wired and wireless

Hi
My customer wants the NGS to install for both wired and wireless users. For wireless users we can integrate it with the WLC but i don't know how it will work for wired users at the same time. Pls suggest.
Thanks

Hi Vishal,
Please note that if you want to return ACLs (and usually in wired web auth you need to), you will have to integrate with ACS as NGS itself cannot return ACLs in the reply radius attributes.
Basically the process is as follows:
1 - Client plugs cable on switch.
2 - Web auth is triggered on the port.
3 - default ACL permiting only DNS and DHCP is applyed so that the client PC can obtain IP address and open a browser.
4 - Client will be redirected to the NGS hotspot login page.
5 - Client will enter credentials.
6 - Client broswer will send an HTTP POST packet containing the credentials.
7 - The switch will intercept the POS packets and retrieve the credentials entered.
8 - The switch will send Radius Access-Request to the ACS.
9 - The ACS will use the NGS as External Identity source to authenticate the client.
10 - The NGS will reply with Radius Access-Accept to the ACS and the ACS will reply to the switch including the ACL in the Access-Accept.
11 - the Switch authorizes the client on the port and applies the ACL it received from the ACS.
Please follow the document Nicolas posted as it is a good one.
HTH,
Thanks

A very strange wired and wireless network issue

Hello,
I have never had any issue at all with my macbook (2008) until this week, I use it both for work and personal use.
Most of time, I'm used to be on customer site, so I use wired and wireless connections depending of the situation....
I have never had any issue at all with wifi neither ethernet connections during three years, until this week... and I can say this is the most strange thing I have ever seen....
Using wired or wireless connection, always the speed of network was really good, at home, many customers, etc never had any problem...
But this week I'm currently out of home, and the hotel where I'm staying I'm having very poor network rate....
Using wireless connection, the download speed is no more than 10kb.... and using ethernet I get less speed... but during the day I'm on customer site, using the ethernet connection and download speed is really good, more than 500k-800k....
I have already tried in the hotel few wifi connections (there are three) and differents wired connections (in diferent rooms) and the download speed is always the same, no more than 10kb...
During this afternoon, I could go into hotel's lab and could connect directly to the router using cable, same speed no more than 10kb....
The most strange thing is on their computers the download speed using wired connection is around 6Mb....
how is possible I'm getting no more than 10kb of download speed when the pc's at hotel using same wired connection gets 6Mb?
I have already deleted current network connections, execute onyx to clear everything, perform dhcp connection, tried manual ip etc, and always the results are the same...
I know there is no problem with the macbook, because it works pretty good at every location I've been... but until this week...
Sincerely I'm getting a little crazy here, I'll appreciate any help!!!
thanks in advance

I've seen something like this on my T400 when it was running Vista. Now that I use Win 7 it's been OK. I rather doubt that your issue is the same but I'm tossing it out here just on the off chance.
Im my case, I had to downgrade my Intel 5300 card to a 5100 (as suggested by a Lenovo 2nd-tier tech) to get things working.
My symptoms were a little different. Wifi was fine until I went back to a wired network. After that, trying to use the same wifi AP as before would end up associated, but no internet access. DHCP wasn't working. The GUI "find" app didn't work as expected either. Some APs showed up, and some didn't.
If I configured for automatic connection to my home AP it would try and fail. Just rebooting at that point would again attempt an automatic connection that would succeed.
What I have noticed now that I run Win 7 is that Access Connections is completely useless. Often the "finder" doesn't show an AP 3 feet away. I didn't notice that this happened after a switch from wired, but maybe.
Are you using Access Connections? If so, you might try uninstalling it.
Sorry I can't be of real help,
Z.

Itunes not connecting via airplay on wired and wireless network

I have some computers on the wired part of my network, and others on wireless. My appletv2 shows in itunes on ALL (both wired and wireless) computers that there exists an AppleTv airplay speaker, but only the computers on the same "side" of the network (wired, or wireless) can actually connect and use the appletv as an airplay device. I have Bell Fibe25 and they provide 2 devices to achieve wireless connectivity, the main VDSL unit that has 4 lan ports on the back, and a basic Cisco WAP610N that connects into one of the lan ports on the VDSL unit for the wireless part.
My firewall is turned off as well.
Can anyone shed some light on why this is happening? My MacPro does not have wireless, and it would not be practical to connect my AppleTV2 to Ethernet cable.
Thanks in advance,
S

I have Windows 7 and the same resolution fixed my problem but you do it in a slightly different way:
Open Control Panel.
Network and Internet
Network and Sharing Center
On the left menu bar select "Change adapter Settings"
Right Click on Network Adapter (Might be Wireless or Wired or change Both) select Properties
Under "The connection uses the following items:" UNCHECK - Internet Protocol Version 6 (TCP/IPv6)
Click OK
Restart Itunes and refresh Connection!
Thanks for your help Shane

Autoselection for a switch between wired and wireless network

Hello,
We currently have a VTC codec installed on a mobile cart that can connect via wireless or wired network. The cart has the Linksys WET610N Dual-Band Wireless-N gaming and video adapter bridge. If you want to go wireless you will have to unplug the CAT5 that goes into the walljack and plug in the cable from the bridge into the codec.
We need a 3-5 port switch. Port 1 will connect to the wireless bridge. Port 2 would be available to connect to a wall jack. Port 3 will connect to the codec.
We need the ability for the switch to autoselect port 1 and 2. If Port 2 is not connected (no link light), then Port 1 will be active. If Port 2 is active, Port 1 will be inactive.
I need to know how to configure the bridge and a network switch if this is scenerio is possible. Any help is appreciated.
Thanks,
Aaron

Well, I thought i had tried this before, but I followed another board's suggestion of turning of IGMP proxy and it is now working. I can see my iTunes server which is wired on my wireless devices.

Using a wired AND wireless network on one machine for better security

It occurs to me that if I could separate my Internet traffic from my LAN traffic, I could have the best security setup, so that machines on my network would only have file sharing enabled for the WIRED connection and I would use the Internet over the WIRELESS connection.
How do I configure my PowerBook and Mac Mini to do this? In the Sharing preference pane, it doesn't allow me to specify which network port the sharing will be active on.
And once I am conncected to both a wireless and wired network, giving each machine 2 IP addresses, how does the computer know to route the IP addresses to the right port?
I'm using an Airport Extreme Base Station (connected to a cable modem) configured to distribute IP addresses to the wireless ports on the computers for Internet and a Linksys router distributing IP addresses to the ethernet ports on the computers with sharing turned on.

in the Thinkvantage Access software, you can set the network preferences. So you can set the Ethernet to be your most preferred network connection method, while your wireless as the second most preferred method. Or which way you prefer.
So for example, when you dock and the computer detects the ethernet network connection, it will automatically switch to the ethernet as it becomes available. And when you undock, your computer will switch back to wireless as ethernet is not available.

Wired and wireless network setup

I have a small home network, wired right now. I would like to add a wireless access point for near future laptops. Can I add a second router that is wireless to my wired network with having to load router software on a second computer. Is this even possible. My network consists of my PC, HP M8300f desktop PC as home base/client and cable modem with linksys wired router, BEFSR41 connected to a dell 2400 desktop. I am wanting to add a linksys wireless router WRT54G some where in the living room for and access point. Do I have to load the software on the Dell PC or can I just plug in router to wall socket and connect wirelessly that way. Thanks for the help. Just thinking out side the box.
OS Vista Home Premium 32 bit
CPU AMD Athlon 64x2 6000+ 3.0ghz
Motherboard Asus M4N78 Pro
Memory 3Gb PC2-5300 DDR2 @ 667mhz
Graphics Card BFG Nvidia Geforce 8400 GS 512MB DDR2
Monitor(s) Displays HP W1907 LCD 19", Gateway HD 19" LCD
Antec Earthwatt 80 plus 500 watts
Hard Drives 640GB 7200rpm SATA (2x320)
Other Info Optical: Super Muliti DVD burner w/lightscribe, Hauppauge WinTV HVR-1800

You can add your WRT54g to your wired network without too much trouble if you follow a couple of simple steps:
Turn off the DHCP server in the wireless-router.
Create an unique wireless network name (aka SSID) and turn on WPA-PSK security.
Make sure the web-page IP address for the wireless-router is set to a unique value different from any of the other wireless devices on your network.
Connect the LAN port of the wireless-router to the LAN port of the Ethernet router. Do not connect to the wireless-router's WAN port.
This configures your wireless-router into a simple Access-Point and is the easiest way to extend your home network with wireless.

How to set up an integrated wired and wireless network

I have an iMac 17" 1GHz connected to a ethernet hub which in turn is connected to a DSL modem and from there to my ISP. I also have a MacBook Pro wirelessly connected to an AirPort Express; the AE is connected to the same ethernet hub through its ethernet port.
I can connect to the Internet wirelesly using the MacBook Pro, but I can not seem to connect to the iMac.
How can I keep the iMac wired and the MacBook Pro wireless, but see both on a network? The AE instructions don't seem to have an example for this kind of network.
Any help would be greatly appreciated!
Cheers,
Martin

Martin,
As Frank said, you'll need a router with DHCP and NAT abilities (nearly all have this) connected to the modem.
But just in case your "ethernet hub" is actually a router, just re-configure the AE not to distribute IP addresses - AirPort Admin Utility - Network tab. Try that and let us know.
For minimal clutter, if you were DSL broadband instead of cable, you could sell the modem, sell the ethernet router, sell the Airport Express and buy a single Ethernet and Wireless DSL modem router - for less than the price of the AE. Some people like to keep the modem separate to make upgrades to the modem cheaper. My solution is to buy a decent modem in the first place, ie make sure it has ADSL2+. Almost all modem/routers do this now, even my ancient ones have firmware upgrades to offer this.
For minimal spend, you can pick up an Ethernet router for about $30. Just replace your ethernet hub with it.

I want to add new mac to existing wired and wireless network

I have a imac 400mz connected (ethernet) to a network - CABLE Modem to Balkin 5.4 G Wire/Wireless router. I have 2 wintel machines hard wired, plus 1 via Motorola PCIMA wireless. I want to add either of the following new Apple products -
mini mac or imac 17 - both have Airport extereme installed. OK how do I get the new apple on to the existing network.
Please advise

On the Mac - click on the Airport menu icon located near the right side of the MacOS menu bar at the top of the screen. A list of all in-range wireless networks will appear. Click on the name of your wireless network to connnect to it. If your wireless network is protected by WEP or WPA security, the Mac will prompt you to enter the key. That's it!

Wired and wireless network problem

I have an Airport Extreme setup with an 20" imac connected thru ethernet. I also have a 17" Macbook Pro connected wireless. Both have no problems connecting to the internet but I want to be able to talk to each other. I checked and the wired network has a different subnet then the wireless one. I would like to have them both on the same subnet but I can't seem to find a setting in my airport extreme that will allow me to change that.. The wired network seems to be the same subnet as the assigned address from my ISP. I only have 1 address from my ISP so the airport is not acting like a switch it is routing the data just creating a internal network based on the ip from the ISP. The wireless is handing out ip address that I have setup in the DHCP section.

Hmmmm
It sounds like you have your AirPort Extreme configured to be in bridge mode? Is this the case?
If it is the case, then you can configure it to "share a single IP address" and then both the wired 20" iMac and the MBP would get DHCP addresses on the same subnet....
If your Airport Extreme is already setup to share a single IP address then the two stations really ought to have IP addresses from the same subnet. Perhaps one of more of them has a static IP and is not setup to use DHCP?

Using both wired and wireless network Access?

I have a ThinkPad 510 with a docking station. Within the same room, connecting to the same network I may use the WiFi with the TP only, or connect using the docking station which is hardwired to the network. TP has W7 installed.
What is the correct procedure for bouncing between these two environments? Is there a setup which will allow
'automatic' access, depending on whether I'm using the docking port, or not?
Thanks,

in the Thinkvantage Access software, you can set the network preferences. So you can set the Ethernet to be your most preferred network connection method, while your wireless as the second most preferred method. Or which way you prefer.

NAC differentiate wired and wireless users

We have NAC installed and are using it control both wired and wireless ports. We also have the Guest Server that we are in the process of implementing. We would like for only users that are created via the Guest Server to use both wired and wireless access, which we are able to do @ this point. Our issue is that we have a Guest account that we would like to restrict to only wired users, this account is posted in conference rooms for internet access only. We don't want this account to be able to be used on the wireless network, is this possible?
Thanks,
Joe

Where are those conference room guests authenticating currently ? Through Nac ? Through webauth on a switch linked with NGS ?
