Fiber Connection with Netgear GS752TS

A dark fiber connection with SFPs is no different than a 1 foot long copper patch cable that connects the two switches as if they were in the same room (less than 1 foot apart). Perhaps you are over thinking it. Just configure the ports much like you would if the switches were next to each other.

A local company has started offering Fiber Connections at much better speeds then Time Warner. They threw in Dark Fiber (Secure Connections) between our two offices (2 miles between the two offices). Unfortunately the techs at the company are not used to Netgear (only knows Cisco) and don't know how to get the two offices to connect over Netgear with our new Dark Fiber. They did get us two SFP connectors with Dual Mode Communication and connected the Fiber on both ends. I am a new Network Admin and still trying to figure this out myself. I thought I would be able to set a routing rule....saying if the IP Address destination is at our second location to send the communication over the Fiber Connection instead of the VPN/internet connection....I have been reading through the Software Admin Manual and searching the net but so far I am not...

Fiber connectivity with ASA

I am having a fiber for internet converted to ethernet using ISP's media convertor . Now that media convertor is not that good and hangs sometimes . Edge equipment is ASA and if I need to put fiber there I would require to puchase SSM-4GE which is quite expensive at the moment for us . I was thinking if I can put the Fiber into Layer 2 switch and take out an ethernet cable from switch to firewall . Put both those ports into VLAN xxx and put ip address to the firewall .
This solution should work and in this case the L2 switch would become media convertor ( 2960S ) . If this is correct can I use this kind of setup on mass scale ?
Comments please

Yes you can do that just fine for the purpose you ask.
As far as scale, 2960S (non-compact) models have either 2 or 4 SFP ports so you could do thise for up to four such connections with the right 2960S model.
Hoep this helps.

Connect with netgear XAV5001

I want too transform the same speed from 1 floor in the house too the second floor
what settings on the airport extreme and what settings on the Time capsule on the second floor

WEP is not worth using at all as it was cracked years ago. Amateur and seasoned crackers can easly break into WEP network with tools readily available on the internet.
The only wireless security you should consider using is WPA or WPA2. Netgear routers support WPA so switch to using that. Macs also find it easier to connect to WPA networks.

Wifi connections with netgear

Just had new Netgear wireless router set up by cable company and everytime my computer is in sleep mode or battery saver it take forever to find the router. Any way to speed the search up?
Imac with Maverick.

Now have the HH3 - and it is NOT possible to set any IP Address Reservation at all, so it is rather insecure. Not being able to restrict what MAC's are recognised as being valid to connect to either the Ethernet or WiFi networks means that literally anyone can connect and use your line - adding their traffic to your use and potentially exceeding the monthly allowance. Plus they can have access to connected equipment and potentially sniff your data or install malware, spyware, Trojans, etc.
This is not what I expect from BT and strongly recommend they have the software/firmware re-written to include that security feature. I gather the Business version has it so why not the Home version?
I am now using my Netgear router/modem and have set it up to connect correctly - and to give me that level of security missing in HH3. In addition, my network printer server works properly - it needs a 'static' IP on the internal Ethernet network that the HH3 could not provide.
So very disappointed in the HH3, but at least I will not have my line being used by others without my knowledge and consent.

Wifi connection with netgear router DG824M - one solution

I have had some problems with connecting iphone via wifi with my home router
Netgear DG824M
I'm still having a problem with the encryption issue but have at least found one solution to another security issue and thought it might help others so i am posting:-
If you have mac address filtering turned on (netgear describes this as only "trusted PC's" can connect) , you may find that you get an IP Address clash when you try to connect your iphone (or some other apple equipment)
I found that this resolved if i selected an "reserved IP address" for the iphone - in my casei chose 192.168.0.10 (since the router allows up to .51)
(the phone otherwise took 192.168.0.3 which clashed with another device)
This was not an issue when "trusted pc's" feature was turned off on the router

Ok guys. This is the simple way i used to connect my iPhone to my Netgear router.
1. In your iPhone, go to Settings>General>About. Then, scroll down to "Wi-Fi Address". This is your MAC address. This you will need in order to authorize your phone in your Netgear page (which usually looks something like XXX.XXX.X.X (where "X" are numbers)).
2. Log in to you Netgear page.
3. On the blue left panel of the screen, click on "Wireless Settings". A new page comes up.
4. Click on "Setup Access List".
5. Click on "Add" to enter the require info needed for your phone to gain access to your network.
6. On "Device Name" I entered "iPhone". This name is irrelevant for i named my iPhone differently and using just "iPhone" worked. So enter whatever name you wish, but keep it simple.
7. Now, on "Mac Address" (the single most important info here) enter the number you obtained in Step 1. Make sure you enter it with the colons (:).
8. Add and apply, and wait for the blue bar at the top of the screen to do its thing. It will take only a few seconds to update the network.
That's all! Connect and enjoy!
I hope this was helpful. Let me know if it worked at [email protected]

Can't get 8900 WiFi to connect with Netgear WGT624 v3.1

I can't get past W002 error. All issues suggested on BB site are okay.
1. WEP encryption is in use and BB sees the router okay. The problem is it won't connect to the router.
2. DHCP is not disabled.
3. DHCP pool is not exhausted.
4. IP addresses are dynamic
5. MAC filtering is off.
I've gone thru the setup process a dozen times, changed passwords, etc. The result is always the same...W002 with no explaination. It would be nice if BB would be specific about the error and maybe one could resolve it. Throwing out a collection of "maybes" doesn't seem to help much.
I've search the net for anything related but can find no similar issues or resolutions.
If anyone has an idea, I'd appreaciate the help.
Thx

I have wireless at home and occassionally it is easier to use the phone rather than my computer to browse. Had troubles at first but I realized I needed a # for security reasons for the system. ARe you sure it isn't something simple like that?

Why does apple tv 2 lose connection with netgear router through a wired connection?

I have Apple TV 2 connected to a Netgear wnder3700 through a wired connection. The Apple TV is up-to-date. However, from day 1 (before firmware updates and currently) apple tv will lose internet connection. All other devices on the network remain connected. the only solution is to physically unplug the the apple tv and let it reconnect on reboot. Same issue exists on a wireless connection.

I would update the firmware of the router

Losing wireless connection with Netgear WG111

Hi all,
during these few days I'm having a *very* frustrating problem.
My wireless dongle keeps disconnecting from the router, and there's no way (that I know of) to bring it back online except from rebooting. What I try to do is restarting the network or stopping the network and dhcpcd the interface. None of those work.
I have no idea of what might be causing this, what and where should I check?
Also, is there any other way to reconnect without rebooting?
Thanks a lot

Everything is set up correctly in my rc.conf, that's why I was wondering why restarting the network wouldn't work. I'll try to see if there's any tutorial on wicd, and hope it will work for me, thanks
Edit
Ok, I have installed wicd, but it doesn't work for me. I can see my router, but can't connect to it when I click on "Connect". I don't understand why... Perhaps I should give a look to NetworkManager...
Edit²
NetworkManager doesn't seem to be the solution for me, since it seems to be working only as a dock app for either Gnome or KDE. I am a Ratpoison user, and have no use of a dock app. I have tried it without the actual gnome-network-manager thing, and it didn't connect me automatically... I wonder what else is there for me...

Impossible connecting with wireless network Netgear WNR 2000

I can not log on to my wireless network (Netgear WNR 2000) with my macbook. My other PC:s work fine and connect always. My Macbook only connect after I have restarted the router. When I use my Macbook in other places I can connect with wireless network. What is the problem?

I'm assuming that you're using the right network password! After that, the most common causes of difficulty are:
- The router not set up for DHCP and so cannot allocate an IP address to the MacBook
- The router has "MAC" Address Authentication (a security feature - don't mistake MAC for Mac[intosh]) turned on and the AirPort MAC address isn't in the pass list.
- The default "Automatic" location in System Preferences > Networks has been modified so that it no longer works.

Unable to obtain ip with wireless connection to Netgear WGR614 router

Pardon my ignorance, I'm relatively new to the Mac world.
I recently purchased an iMac and at the same time purchased a Netgear wireless router.
When hardwired to the Netgear, I have no issues. I tried connecting via wireless, and keep getting the self-assigned ip address. My wireless network is detected and the Airport card connects...full strength. I also have a laptop running windowsXP, and it connects with no issues.
I have tried some of the suggestions mentioned in the discussions. Power cycled the Netgear. Changed channels...from 11 to 10. That didn't help so I went back to channel 11. I have security disabled...trying to keep the configuration as simple as possible until I can get this working.
If anyone can share some thoughts/ideas, it would be greatly appreciated.
Thanks.
-Tim

I had to go into /Library/Preferences and dragged SystemConfiguration to my desktop. I restarted the iMac.
After it booted up, I went into System Preferences => Network; created a new Location and used the "Assist Me" tab at the bottom. It walked me through setting up the Airport again and this time it worked.
For anyone that does this, once you confirm your wireless connection is working, take the SystemConfiguration on the desktop and drag it to the Trash.

WRT54G not connecting properly with Netgear switch

I have a WRT54Gv4 which I've been using as both a WAP and a wired switch. I now have too many wired devices to plug into the built-in switch, so I tried to expand the WRT54G using a Netgear FS108 8-port switch. The WRT54G and the FS108 both work perfectly well when not connected to each other, but all hell breaks loose as soon as I plug them together. If I plug the cable into a regular port on the FS108, then the "network activity" light on the corresponding WRT54G port blinks rapidly and continuously. If I plug the cable into the uplink port on the FS108, then the "network activity" light on the FS108 port blinks rapidly and continuously. I get around 50% packet loss trying to communicate between a computer plugged into the WRT54G and another computer plugged into the FS108. I've already tried 3 different cables between the WRT54G and the FS108, and all have exhibited the same problem. I have also tried all kinds of power cycling of the different devices, and nothing I have done has worked.
So I have two questions:
1) Has anyone successfully connected a Netgear FS108 to a WRT54G? If so, how did you do it?
2) Has anyone successfully used a Linksys SD208 or EZXS88W switch with a WRT54G? I'm going to buy one of these to replace the FS108 if nobody can answer the first question.
Thanks.

If you have McAfee anti-virus, then I guarantee IT IS a McAfee + Vista issue. In the Firewall settings for Vista, enable Peer-to-Peer and add and enable ports TCP 5357, TCP 5358, UDP 3702, TCP 2869, UDP 1900, UDP 137, UDP 138, TCP 139, TCP 445. THEN, disable Vista Firewall and enable McAfee Firewall. Click on Internet & Network Protection and then Configure. This is where the McAfee Firewall protection is enabled. Click on the Advanced tab. Click on Grant Full Access and apply. Click OK, close out and reboot. Your system will utilize the McAfee Firewall and not the Microsoft one, and as long as you have WAP encryption and a private network, your Linksys router will allow printer and file sharing and be protected.

Netgear router won't let me connect with a network my new roomates use

I have had this problem before connecting to wireless networks, although not all of them. I just moved in with a friend who gave me the network name and password. Although my powerbook G4 sees her network, it shows an error message when i try to connect with the password. She set up the Netgear (WGT624 v3) router using her DELL and everyone else in the house (using PC's) don't have this problem. I'm wondering if we need to go through what she has set up on her computer, because I must have tried everything on mine! Does anyone know how to solve this problem?

Hi tracie,
thats OK I know how hard wi-fi is to setup, I've spent many hours in the past trying to figure out how to set mine up! Its usually the simplest of things.
Your MAC address or Airport ID (as Apple call it) is a string of a series of 6 two digit numbers/letters separated by a colon e.g. 00:2b:35:18:af:32
This identifies your Airport card on a network & your address can be viewed in System Pref.s/Network, then from the drop down "Show" menu choose "Airport" & then click the Airport tab that appears in the row of buttons & you should see your Airport card's MAC address (Airport ID). But if you cant find that option don't worry about it.
While your in Network Sys Pref click show port config. & drag the Airport entry to the top of the list.
If you do try WEP again, go to router's
Wireless Settings > Wireless network
& insure the Mode is set to "g and b" just incase.
Then > Security Options & click WEP.
Then in > Security Encryption > Authentication type
set to Shared key
Also > Encryption Strength
set 128bit
After that go down to > Security Encryption (WEP) Key
in Passphrase enter your new password & click the Generate button on the right - this will bring up your HEX key in the checked "Key" box below.
write this new generated key down & click Apply & log out.
Now on your PB open the Airport network entry window, change top box from "WEP Password" to "WEP 40/128-bit HEX"
Then enter the generated key you wrote down into the box below, & click ok/join.
Keep 'em crossed & you "should" join.

You're welcome.
Voicemail is left at your carrier's server. That will continue to work unless you report your iPhone as lost or stolen with your carrier.
You may never find it again and you can't if the iPhone remains offline or out of service which means the iPhone is powered off or doesn't have cellular reception.

Two switches connected with fiber in mode trunk - Problem

Hi to all.
Iam new in the forum, and my english is bad.
I want to post a problem. I have two switches connected with fiber in mode trunk, in the switch C3550 i have this configuration:
interface FastEthernet0/1
description Enlace LAB Medicion
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
duplex full
spanning-tree portfast
In the switch C2960 this configuration, on interfaces Fa0/48, Giga0/1:
interface FastEthernet0/48
switchport trunk allowed vlan 1,20,229
switchport mode trunk
spanning-tree portfast
interface GigabitEthernet0/1
switchport trunk allowed vlan 1,20,229
switchport mode trunk
media-type sfp
duplex full
spanning-tree portfast
The problem:
The ip phones with Voice vlan (vlan 20), not find the DHCP server located in the data vlan (vlan 229)
However, using the command:
#switchport trunk native vlan 229
The result is the voice vlan works, but the data vlan not and viceversa depending if the native vlan 229 is present.
I will appreciate any suggestion.

leolaohoo.
The configuration on ports switch C2960, have the mode access with voice vlan 20:
interface FastEthernet0/1
switchport access vlan 229
switchport mode access
switchport voice vlan 20
spanning-tree portfast
interface FastEthernet0/2
switchport access vlan 229
switchport mode access
switchport voice vlan 20
spanning-tree portfast
I will remove from trunk links:
spanning-tree portfast
Thanks alot.

Very low transfer speed issue on SUN4270 M2 server connected with nexus 5548 switch on 10GB fiber.

                   Hi,
I have 2 SUN 4270 M2 servers connected with Nexus 5548 switch over 10Gb fiber card. I am getting performance of just 60 MB per second while transfer of 5Gb file across 2 servers. The similar speed i use to get on 1Gb network also. Please suggest how to improve the tranfer speed. On servers, ports ET4 and ETH5 are bonded in bond0 with mode=1. The server envrionment will be used for OVS 2.2.2.
Below are the details of network configuration on server. I quick help will be highly appriciated--

Hi,
Thanks for reply..but the RX errors count is keep on increasing and the transfer speed between 2 servers are max 60MB/ps on 10GB FC card. Even on storage also, i am getting the same speed when i try to transfer data from server to storage on 10GB FC card. Servers and storage are connected through Nexus 5548 switch.
