I have a Router 877 and a switch 3750 also a 10 mbps internet connection and I want to share the internet connection to 5 different vlans with a maximum of 2mbps each one or 2 mbps guaranteed. The switch and the router are connected for a trunk port and the vlans are defined in both devices. I have tried many configurations of this with no success.

300 M bps drops to 150 M bps when it recycle power. I met all requirements for 300 M bps connection this happen only in 2.4 g Hz Band width.
View 1 Replies View RelatedI have a Netgear CG3100 modem hooked up to a Netgear WNR2000 router. Both are sending out signals, the CG3100 on channel 11 at 40 Mhz and the WNR2000 on channel 1 at 20/40 Mhz. I keep the WNR for legacy devices while the CG is for N devices only. They don't seem to interfere with each other much.Currently my computer is the only device connected to the modem wirelessly, with the only wired connection being the router. As I write this, the connection has actually dropped to 26 Mbps in the Wireless Network Connection Status window. I understand that this number drops under network load, but there doesn't seem to be any at the moment. If I go into the control panel and simply click apply, the connection jumps back up to 150 Mbps. However, this always drops back down, sometimes immediately, sometimes after a few minutes. It usually settles down at 72 Mbps, sometimes 54 Mbps.My wireless adapter is an ASUS PCE-N13 with v3.2.7.0 Ralink drivers. OS is Windows 7 64-bit.
View 6 Replies View RelatedWe have a new building where we added 3 network closets with 3750x stacks.We have 2 fiber gig ports connected to 2 microwave units and etherchanneled the to ports
We have the same setup at the corporate office except the connection is 2 fiber gig ports on a 6509. The 6509 is doing the routing
Now the problem is that we lost the connection to the management interface on only one of the three closets after a few days running. But some workstations at the corp office could reach it... others could not. The workstation were on the same VLAN. We solved the problem for a few days by shutting on of the fiber ports on the etherchannel. But is started happening again... now with PCs being installed at the new location.
The PC that was not working on the 3750x side could ping across to the 6509 but no further then that. It seems like an arp issue not routing because some devices are reachable and fully operational throughout the network.

View 8 Replies View RelatedInstallation of 2 x 4 Mbps MPLS circuit on primary router (CISCO 2951) and 1 x 8 Mbps Ethernet link on secondary router (Cisco 2951). We have successfully implement the primary router with 2 x 4 Mbps MPLS circuit. Site is having two computer room CR1 and CR2 and distance between both room is 200mts. CR1 is having primary core router and primary core switch where the service provider terminated the new MPLS circuit and we have done the successful implementation. CR2 is having Secondary core router and secondary core switch where we needs to have the termination of Ethernet link but service provider has delivered the Ethernet link on the CR1 which is incorrect DMARC Location.
Both the computer rooms are connected via optical copper can we use that copper to connect the circuit on CR2, as per my understanding we can use the optical fiber to connect the wind circuit on secondary router on CR2 by using the media connector.
I just ran some speedtests om my PC on the advice of my isp to see if my Linksys WRT54G router might be bad. As a result, I found that the router might not be entirely bad, but it might not be entirely good, either. I got .77 Mbps dowload and .17 Mbps upload on the first speedtest. I got .43 Mbps download on the second speedtest and the speed test hung hear the end. When I connected an IMac to the cable modem with an ethernet cable, the IMac ran strong. So the tech thought I should get a new router.
But wait a minute, isn't there a network adapter in the PC that the router talks to? Might the adapter be the problem, not the router? So I speedtested the wireless network to the IMac. That speedtest was fine, tiptop, like the ethernet direct connection test noted above. Did that tell me that the problem is in my PC network adapter, not the router? Then, I retested (speedtested) the connection on the PC and it was fine...excellent. Good up and down speeds, no hangs.Then, I checked the PC adapter (a Belkin). I saw three adapters on Device Manager, including the Belkin. I downloaded new drivers for the adapters (except for the Microsoft Virtual WiFi Minipoty Adapter - because it got a warning that the download software wasn't signed and might harm my computer).
So I have installed my new E4200 version 1 and I am disappointed with the speeds. My computer has a wireless N card and gigabit Ethernet compatibility. I am currently getting a miserly 54 mbs wireless and 100 mbs on the wire (connected with cat6 all the way)... Anything I should try to get close to advertized speeds?

View 1 Replies View RelatedI was wondering why the heck I'm getting BELOW 1 mbps toward my internet connection? I look at my wireless signal, and it's full. yet, I go on speedtest and have about 0.20 mbps.
Info - My parents pay nearly $100 for this bundle thing with the internet, phone, and something else, I think TV.
provider - windstream
router - F@ST 1704
Also, the router is currently on top of the main computer in the office, on top of the router is a house phone.Yet, if I move the house phone, nothing changes. The computer is on the floor.Should i move it? Would this improve my connection?Even the main computer that's wired with the router gets the same mpbs as wireless.
I have a desktop and laptop here, the desktop being mine custom built wireless and all, and my buddies desktop.The issue that I'm having is that my desktop, regardless of wired or wireless gets 25 mbps down speed, and the laptop gets only 2.5 mbps down speed wired or wireless

View 1 Replies View RelatedWe have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?
I'm using an HP G60 laptop, running Win 7 Pro x64 SP1, fully patched. I'm usually in the home office, connected to a D-Link DIR-615 router (h/w: E3, f/w: 5.10, the latest). The internal Atheros AR9285 N150 wireless adapter has never been as reliable as I'd like, so decided to purchase a USB N300 adapter. I bought a TP-Link model for $10 and started using it. For some reason, it would only connect at 150, unless I ran the router's Web interface and saved the wireless settings, even without a change, at which point I'd see 300 Mbps. However, at the next restart after hibernation, the connection with the DIR-615 would fall back to 150.
I stepped on the TP-Link USB adapter and broke it. Oops. Decided to purchase a D-Link DWA-131 (h/w: A1, f/w: 1.21, the latest) 'cause it's compact and the box says that, "For Optimal Wireless Performance +Use With Wireless N 300 Router (DIR-615)."Expected 300 Mbps, but it connected at 65. Argh. Did the trick again with the DIR-615's Web interface, and saw 150. But after restart from hibernation, back down to 65. Unable to achieve 300 Mbps, unlike the cheap-o TP-Link adapter. Router is configured according to Lycan's sticky note. Router's Wireless Status shows a signal of 39%, and the router is in the next room in a wood-framed building.Is this as good as it can be? Looks like the DWA-131 is coupla years old with no new drivers for Win 7. Ran the DSL Reports Java speed test, and seeing 18+ Mbps d/l, and 1.8 Mbps u/l, which is about average from Cox here in The OC. If I can't get a faster connection, then D-Link's claim of "optimal performance" is misleading.

Recently, I am having an issue with my LAN connection. After I boot up, I get the "two computer" icon in my system tray that stays active. When I mouse over it, it says "Local Area Network Speed 100 Mbps Status - Acquiring Network Address"However, I am connected to the internet and there seems to be no connectivity problems. And it has an IP address: 192.168.1.66 This "acquiring network address" will persist forever, (although sometimes it will quit). If I right-click and do repair, the problem disappears immediately.I am running Win XP SP3 and am connected by ethernet cable to an ATT-U-verse Gateway.For what it's worth, Windows takes a very long time to boot up -- it takes a while for the icon to appear, and then the boot process completes.

View 2 Replies View RelatedI have a network with a Catalyst 3750 as the main switch and then some Catalyst 2960 switches that are plugged in to that. I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?

View 2 Replies View RelatedI have a network with several catalyst 2960 switches and one catalyst 3750. I have created two VLAN and set up the proper routing and everything is working fine there. I have a client/server application that used multicast in the initial start up for the client to determine available servers, the issue is one of my clients is on a different VLAN then the server. I am able to route the multicast using MVR as long as both the server and the client are plugged into the 3750 by creating a static route, making the server a source port and the client a receive port. Unfortunately I need the client and the server plugged in to different 2960s. My question is how do I establish multicast routing between the two and perferably do it dynamically (always route multicast traffic from one VLAN to another).
