Multiport Network Adapter Versus Separate Network Adapters

Apr 2, 2013

I am looking for some information concerning network adapters. Many server vendors (HP, Dell, IBM and so on) use multiport single network adapter (one card,several ports -let's assume 4 ports). What resources are shared in multiport solution? For example:

- does multiport nic has significant limitations? For example, it's cpu cannot handle full 4-port load?
- interrupt sharing?
- buffer size?

Linksys Wireless Adapters :: WUSB600N Network Adapter / Lost CD's?

Jan 18, 2011

I am trying to connect to the internet a second, older tower using the WUSB600N ver 2 adapter, the unfortunate part is that I have lost my CD's that originally came with the adapter. I am on my primary machine right now so I am able to get online. I am wondering if there is a way that I can get the proper drivers or software, put them on a USB drive and then put them on the computer that I am trying to connect?I have already tried this, but I cannot seem to get the steps right or I don't necessarily know what I am doing. I am at the Linksys support Page [URL] and I have tried to do as I mentioned before, but I am sort of just expecting it to GO and its not working. The computer i would like to make the WUSB600N adapter for is running windows XP pro Service Pack 3?

Linksys Wireless Adapters :: AE3000 Adapter Network Connection Failure

Feb 27, 2013

I just purchased 2 AE3000 adapters to update my wireless network and cannot get either of them to connect to my wireless network through either of two computers I tried. It hangs for a while looking for address and then I get the 'limited or no connection' note. But yet when I plug in my old AE1000 adapter into either computer I get connected right away. I've looked under the device manager and it shows up there, the LED lights come on and I see my wireless network show up on available networks. I am using the windows wireless manager in lieu of the Linksys one and as such I don't think any specific drivers are being used. I bought two updated adapters to start with is to keep current and NOT have problems.

Linksys Wireless Adapters :: AE3000 USB Adapter – False Network Detection?

Apr 17, 2013

I recently purchased a Linksys AE3000 Dual-Band Wireless-N USB Adapter as an upgrade to my Dell Desktop Computer and to compliment the Linksys EA4500 Router that I recently installed. Generally it seems to work well and the 2.4 GHz network status typically shows speed to be 450 Mbps. However, I’ve discovered if the computer goes to sleep based on my power plan, when it comes out of sleep the “Available Networks” will show the network I’m connected to (2.4 GHz network) and a false network identified as “Other Network” with a Red “X” where signal strength would normally be. When I mouse over it; it shows Network Name: Other Network; Signal Strength: Excellent; Security Type: Unsecured; Radio Type: Unknown; and SSID: Other Network.
 
Initially I thought this was an anomaly caused by having both bands of the Router (2.4 and 5.0 GHz) set to the same SSID, so I changed the 5.0 GHz band to a different SSID and set my Media Players to access the new SSID. However, now when the computer comes out of sleep mode, Available Networks will initially only show the Router’s 2.4 GHz SSID and the phantom “Other Network”. It takes a while before the Router’s 5.0 GHz SSID shows up. We live in the country, so there are no other networks close to us, just my home network. It never shows the “Other Network” when I start or restart the computer and if I disable the adapter and then enable it, the phantom network goes away until the computer goes into and out of sleep mode again. Also, I uninstalled and then reinstalled the Driver and then reinstalled the Adapter using the Cisco Connect Software and the problem still exists. Finally, I disabled the Router’s 5.0 GHz network and the phantom network no longer appears under any conditions. The Dell (Atheros Communications) Wireless Card in the computer doesn’t have this issue under any scenario. On both the AE3000 and Atheros Adapters the 2.4 GHz network shows a signal strength of Excellent (5 out of 5 bars) and the 5 GHz network shows Good (3 out of 5 bars).
 
How to correct this issue? With the issues I’m having with the EA4500 and the AE3000; they are both probably going back to Amazon.

Access Internet Using Wireless Network And Printer Using Separate Wired Network At Time?

Apr 4, 2012

I have 4 computers (3 laptops, 1 desktop) in a shared office. We get internet access using their wireless network. All works fine. However, I need to share a printer amongst all of the computers. The printer is LAN enabled and I would normally just put all the PCs on a hub, together with the printer and share it that way. BUT my question is can we access the internet using the wireless network and the printer using a separate wired network at the same time?

Uninstalled Network Adapters As Laptop Was Acquiring Network Address?

May 20, 2012

... and made a fundamental mistake of uninstalling adapters hastily without looking into it. Now when I try to re-install the adapters, I'm running into difficulties. Specifically, I don't have the CD-ROM I originally must have used, and the following message is popping up: "Files Needed - The file 'atl02_2k.sys' on Atlansic Fast Ethernet Adapter Installation Disk is needed. Type the path where the file is located and then click OK." Unfortunately, I don't have any idea if there is a path where this is located, so installation cannot complete.

The reason I took this option to begin with was that the wireless connection on my laptop [Asus, Windows XP] was acquiring network address without ever connecting fully to the internet. I had previously tried another of other methods, such as manually entering an IP address, to no avail.

i am having a problem with my desktop right now, just recently i re-installed Windows7, a clean format... but then i suddenly noticed that i cant connect to the internet, no network adapters are detected on the Network Connections, its empty i looked at the Device Manager and saw a yellow warning on realtek rtl8139/810x family fast ethernet nic, i download the driver using my laptop (wireless connection)... and installed that driver on my desktop pc then checked the device manager once again, but it still has a yellow warning.i dont know what to do anymore, and at the last screenshot theres this error message: This device cannot find enough free resources that it can use. (Code 12) If you want to use this device, you will need to disable one of the other devices on this system.i have two lan cards, one at the motherboard(not in use) and the other PCI-E lan card (tp-link ) ...im just wondering if that Realtek i just installed is the lan driver for the motherboard?

Use Two Separate Internet Connections On Same Network?

Feb 4, 2013

Internet connection come from an ethernet port in the wall. Cat 5 then goes to the switch and then to various computers.Desktop #1 has a IP of 10.1.1.133, sub 255.255.255.0, default gateway 10.1.1.200, DNS 10.1.1.4I want to be able to attach a cat5 cable to the LAN port of a Linksys WRT 54G going from the switch.What is the settings I need to select in the Linksys router for this to work.DHCP - Off. I guess the LAN IP of the router must fall in the range of the Main DHCP pool. Could I select anything in the 10.1.1 100's as long as another computer did not have the same IP. The starting IP of the linksys router stays in 192.168.1...... and doesn't looked like it can be changed. Does any Laptop that connects wirelessly to the linksys router need a static IP or can it obtain an IP address through

Installing Second Wireless Network Separate From DSL?

Feb 2, 2013

I have a DSL modem with wireless networking, and I am trying to install a second wireless router for a separate network. The standalone wireless network has five laptops networked to a sixth laptop, in a server/client setup. To complicate things, I am plugging the server laptop into a LAN connection on the DSL modem. The server shows both the LAN connection with internet access, and the second wireless network without internet access. The client laptops just show the wireless network, without internet access.

This is exactly what I need - internet access for the server but no access for the five clients. I have each wireless router on a separate channel and only auto connect to the standalone wireless network. Is there anything I need to do to the setup of either of the routers to avoid problems?? The wireless network without internet access seems to be abnormally slow in response and I am wondering if there is any interference between networks. None of the laptops are accessing the DSL wireless network, but I still need that DSL wireless capability for other computers in the building.

Home Network :: Multiple Router Networking Versus Adding A Switch?

Apr 22, 2011

on my home network I currently only run an Airlink101 AR675W router. We have a couple issues with this. The router for one is in my basement and there are points in my house that have low signal strength, especially upstairs in the far corners of the home. Second is I am currently running my home PC as a media center but it is set-up wirlessly so streaming is clunky and jittery. Also on this network is 3 X-box's wired, a PS3 running wirless, 2 PC's wired in, 2 wirless laptops and the afore mentioned wirless PC. A lot of weight for the network. What I want to do is move the router upstairs, hardwire it into my wireless PC (the one doing the streaming) and connect a second router (an identical make and model I am buying this weekend) downstairs which will be basically used as an "expansion" of the wirless and a switch for the hardwired devices downstairs. would this be better than simply moving the wirless router upstairs (hardwiring my PC) and putting a 5 or 8 port switch in downstairs for the X-box's and 2 wired PC's there?

Cisco Switching/Routing :: Network Performance - 3850 Versus 2960

Jun 3, 2013

I have a network coming up for a switch refresh.  Management is pushing for 2960s and I would like 3850s.  We are running Cisco Voice and Video over the network.  I saw a few things that seemed to be in favor of a Layer 3 switch vs. a Layer 2 switch.  Some items like better performance due to switching based on IP vs. switching based on MAC.  Some information that will show the 3850 to be a better choice or that the 2960 is capable.

D-Link DIR-655 :: Separate Two Groups On Business Network?

May 7, 2011

I've got a business network that I'd like to separate two sets of computers all together (thinking through a firewall rule or other method). Here's a text example of what I want to achieve:

Group A: PC 1, PC 2, PC 3 (can see each other and share files within this group)

Group B: PC 4, PC 5, PC 6 (can see each other and share files within this group)

But Group A & B can not see each other and are blocked from accessing each other.Can this be done with the DIR 655 or do I need to upgrade? Also, these two groups will be sharing the same internet connection.

Routers / Switches :: Setting Up A Network With Separate Subgroups

Jun 13, 2012

I have a 4-port Netgear modem/router (DG834), and need to distribute its Internet connection according to the following criteria:

1.There are 11 access points (3 wired, 8 wireless) across 4 floors of a building - all cabling is from a central point, which will connect through a switch.Cat 5e cabling is in place.
2.The wireless points need Power over Ethernet connections
3.The 4 router ports serve 2 PC's and a printer in an office, the fourth being the connection to the switch.
4.There must be network separation so that:
- all points have Internet access
- there are three separate groups - one for the office, one for staff (wired) and one for guests (the wireless points), the purpose being to ensure that no user in one group can access any user's device in the other 2 groups. I'm assuming VLAN is the method for this.
5.Traffic on the network is likely to be fairly low casual use of the wireless ports, the office PC's only being used for Internet access and email no transactional systems, large databases or other resource / network-intensive functions.

1.Both the Netgear FS726TP and GS724TP look as if they will do what I want, using WNAP210 wireless access points. Could I achieve the same outcome with 2 x GS108PE switches? Any other hardware recommendations?
2.Do I need any additional hardware?
3.Are there any other considerations I have not thought of?

Sharing :: Creating Separate Work-group On One Network?

Feb 1, 2011

I'm in a house on a network that has 2 Macbooks, 4 notebooks running either Windows Vista or Windows 7, and 3 desktops running either Windows Vista or Windows XP. (Sidenote: No, they're not all accessing the network at the same time; actually some of them are hardly ever even turned on but it's important to include them because of the questions to follow.) Out of all those machines, one desktop running XP and one notebook running Vista are mine.Now, my family's pretty private, so we have file sharing turned off on all the computers. The problem is it's really a pain to have to transfer files between my laptop and my desktop, which I do fairly often because some of my schoolwork is done on the desktop (bigger screen), while some is done on my laptop (portability), and I also have a partition on the desktop's hard drive specifically for backing up files. When I want to transfer files, whether it's one file or 10,000 files (which I had to do the other day, actually), I either have to:

a) e-mail the file to myself if it's not too large and open it on the other machine

b)use my flash drive to transfer files

c) use a usb transfer cable, start the software, log in to the connection, etc etc.

simply create a new Workgroup on the network with just my 2 machines in it, so I can put all the files I want to share/move between them on the network instead of manually transferring them. I've already taken care of that step (creating the Workgroup, that is), so for the sake of not being confusing, I'll call my network "Network" and my workgroup "Mygroup" and whatever workgroups the other computers might be in "Theirgroups". Now that I've figured out that it's possible for Mygroup and Theirgroups to co-exist on Network, what about the actual file sharing? If I set up file sharing will only the 2 computers in Mygroup have access to them, or will the computers in Theirgroups have access as well since we're all on the same network? If the computers on Theirgroups will have access as well, is there any way I can make it so that only Mygroup will have access?

Cisco :: WS-C2950-24 Separate Guest Clients From Domain On Network?

Jun 8, 2012

I am playing around with a WS-C2950-24 running IOS 12.1(22)EA13. I would like to separate guest clients from domain clients on the network (for a start) so that guest clients only get access to internet and i have created three vlans for this purpose. Vlan 10 - internet, vlan 20 - internal, vlan 40 - guest. I have also set up a trunk link on the internal network.since the 2950 does not offer routing capabilities i assume i need to to the routing between these networks on another box. I am planing to do this on a linux machine. I have set up the same vlans on the linux box.

My question is how do I configure the cisco correctly so i can reach all the networks on the linux box. The cable that runs between the cisco and the linux box is connected to vlan 20 - internal and is defined as a trunk port allowing all vlans ( switchport trunk allowed vlan all ) with vlan 20 as native.it looks like only vlan 20 is using the cable that reaches the linux machine. 2950 ----- unmanaged switch (not replaced yet) ---servers

Cisco Switching/Routing :: 1800 - How To Use Gateway On Separate Network

Sep 30, 2012

I've just started out playing with a Cisco 1800 router to gain some knowledge of Cisco devices before taking a CCNA. I also have a 2950 switch but will start with the router.
 
I'm using an Android phone as a wireless Internet access point.  This issues IP addresses by DHCP in the 192.168.43.x range with 255.255.255.0 subnet.
 
Also I have a Linksys WRT54G router running DD-WRT firmware acting as a wireless bridge to the Android phone, and it has 4 LAN ports.
 
This bridge is up and running and I have successfully connected my laptop to the Linksys for testing and can use the Internet provided by the phone.
 
Connected to the Linksys is a Cisco 1800 router. Connected to the router is my Citrix XenServer PC and a NAS box.
 
The XenServer and NAS are on another network 07.05.19.x range with 255.0.0.0 subnet using their own static IPs. One of the virtual clients on the XenServer will be a DHCP server to service other virtual clients.  All still in the 07.05.19.x range.
 
Basically I want the devices on the 07.05.19.x IP range to be able to use the Internet gateway at 192.168.43.1 to access the Internet.
 
How would I set up my 1800 to achieve this?
 
Also, am I right in understanding that the 1800 will ignore DHCP leases from the Android phone due to it being a Layer 3 device.

Networking :: Second Separate Network Using Single ISP Provided Address D-Link DI-624

Nov 25, 2011

I have a standard home network consisting of internet access provided by my cable company which is then disseminated to a variety of wired and wireless devices via a router.

I would like to create a second wireless network that is separate from my current one. This new wireless network would have extra access controls including access restrictions to some web sites using both IP address restrictions and using the OpenDNS DNS servers.

The picture below illustrates the current configuration. The question is: how can I connect ROUTER B to the internet using my current equipment (without buying another IP address from the cable company)?

W
MODEM --> ROUTER A --> ANTENNA <------> COMP 3
1 2 3 4
| |
| |
COMP 1 <---' | W
| ?? <--> ROUTER B --> ANTENNA <---> COMP 4
COMP 2 <-----' 1 2 3 4

W = WAN port

So, in the above picture, COMP 4 is connected via wireless to this second network and cannot access anything on the first network and uses different different DNS servers.

In case it matters, ROUTER A is a Linksys WRT54GL while ROUTER B is a D-Link DI-624.

Cisco Firewall :: 6500 Separate Internal Server / HQ Network From 3 / 4 Different External Connections

May 21, 2012

I am using a 6500 with FWSM. I need to separate an internal server/HQ network from 3 or 4 different external connections. The external networks do not necessarily need to be isolated from each other.I have the option of using a 3 layer model: L2 Access layer to SVIs on the Distribution layer and then L3 to the 6500.L2 Access, connecting directly to the 6500s, with the SVIs on the FWSM.Is it better to have the FWSM outside the MSFC or Inside? Am i correct in thinking that "inside" vs "outside" is determined by whether the SVI's are configured on the FWSM or the MSFC? is there any performance impact from having the FWSM doing the routing instead of the MSFC.If the vlans are all configured on the FWSM, what is the 6500 doing, other than providing switch ports?

Cisco Switching/Routing :: 5510 Isolating Switch Ports For A Separate Network

Feb 2, 2012

I have to configure failover Active/Standby on my ASA 5510.I am wondering how i could do for the outside interface, i mean, actually the ASA1 outside interface is linked directly to our Internet router.So now if i have to add ASA2 connecting to that router i will need a switch between them.I have already a switch for DMZ & LAN.The thing is that i will have to allow 3 switchs ports to communicate with each others.

- 1 for ASA1--outside
- 1 for ASA2--outside
- 1 for Internet router
 
How could i isolate these 3 ports to make them communicate alone ? Should i use VLAN for that ?And if i use VLAN, will this require to make any change of configuration on my firewalls (ASA1 & ASA2) outside interface ?I am a bit lost with this, if i am correct i will not have to do some "vlan tagging" on the firewall itself ?
