Internet Bandwidth Not Reaching Potential
May 9, 2011
I recently upgraded to the 107Mbps service from sudden link. The tech tested my signal coming into the house and it proved to be very strong. I then hooked up the Motorola Surboard Docsis 3.0 modem via hardline to my iMAC and my brother's PC running 7. He and I both did the speed test and we are only getting 50-75 Mbps. The tech claimed we needed to wait and the speed would build up, but its been 24 hours and still around the 50-75 range. We also got higher rated cables to ensure that there was no loss. I made sure the settings in the modem was set to send out 107Mbps and the Tech agreed that the modem was capable of delivering the speed. Both my brother's PC and my iMac are within 3 to 4 months old. The modem is also about 6 months old. why the speed is not clocking at or near 100Mbps.

CBWFQ kicks in when the interface becomes congested and there is no available space in the queue but I need to find a solution to the scenario below:Im using a Gigabit interface on the 3945 Router that connects to the ISP. The ISP limits bandwidth to 60Mb so I need to make sure when I reach the limit of the 60Mb the router starts using the BW percentages defined in the policy-map using classes. any kind of traffic go out as it wants but as soon as the 60Mb limit is reached, the priorities defined by the traffic classes will kick in just as if the interface ran out of queues (as CBWFQ usually works).

Default route is pointed to firewall but still it is taking the path directly to the ISP from the router without going through firewall.

Am looking at purchasing a router that is capable of serving a WAN bearer at up to 1Gbps. The 3945E has had good reviews as a high throughput router but the datasheets suggests performance of 350Mbps. It also states that additional performance can be ensured by adding SPE modules. Whether the 3945E could achieve up to 1Gbps with SPE modules?
If the 3945E can't achieve such performance, The key features I am after are:
IPV4 and IPV6 support
L2tpV3 support
BGP
IP SLA
1Gb Copper Connections on-board with capability of at least 4 Ports

I have a Cisco 3560 running as a Level3 device in my network running 10 V LANs and routing between most of them (nothing complex with ACLs) and running spanning-tree mode pvst. The main network is run on a net gear GS748TPS stack of three switches running MSTP.
I have just bought an additional 3560 and a 2960 to plug in. I have set them up with IP addresses and then plugged them into the net gear. This brought the whole network down until I unplugged the new switches.
I have confirmed the IP addresses aren't duplicated and that DHCP is not running on the switches so I can only assume it's something to do with DHCP. I cannot afford for the network to go offline again, so is there anything I should check? Am I running incompatible spanning tree methods between the net gear and Cisco devices?

I have 2 SSIDs mapped to 2 VLANs (other VLANs are configured, but not used) Security is set to WPA2
What do I need to change to get higher connection speed? What is the highest for this model? Why won't it let me select 40Mhz channel width? Telnet says on 20Mhz available (GUI says it is in "Least congested" mode even though it is not)

I'm running an Optiplex 330 with the Broadcom NetXtreme 57xx Gigabit ethernet card.
The computer is running Windows 7, 64bit, but there do not appear to be any drivers for that OS.I tried selecting Vista 64bit, but there were no drivers. The Vista 32bit doesn't work.
Then I went to Broadcom and found these drivers: [URL] the W764bit drivers didn't change the fact i'm still on a 100Mbit card (as seen on Local Area Connection Status screen and the Device manager)

-Taking all of the bandwidth.
-My computer is causing it.
-Our Internet providers are Comcast(cable) for default and Frontier(DSL) for backup; business class.
-Normal: 6Mbps down, 4Mbps up; Abnormal: 0.4Mbps down, 0.2 up; around those numbers.
-Possibly a virus.
-Task-manager shows as much internet use as usual, even if it is apparent that my computer is using allot during that time.
-Random times.
-Might have settings allowing it to take however much broadband it wants, I do not know if there is such a setting or not.I only have a day or so before my dad cuts me from the internet.

I'm pretty new to this, and I've been trying to read up on what I should do. Here's my situation: we have a new 15mps internet connection coming into our building. We also have a new 891 router. We would like to devote 1.5mbs at the highest priority to one LAN which is just used for VOIP phones. We would like to allow one of the other tenants to use up (but no more than) to 5mps for their LAN, and we'd like to be able to use up to 13.5mps for ourselves if it's available, or at least 8.5mps (15-1.5-5=8.5).
From searching in here and reading the various articles on policing and shaping, I'm thinking that we'd want to set up Class-based weighted fair queuing on a per-interface basis, and have one interface connected to our VOIP switch, one connected to the other tenants switch, and one connected to our firewall. Does this sound like the right way to go? And would anyone have an example of a configuration which achieves this?

We have 1 mpbs bandwidth line, but most of the time we are getting only 300-500 kpbs download speed, i want to send statistics report to our ISP, what will be best procedure to test the bandwidth report, i have checked in some websites like bandwidthplace and speedtest but these sites are not accurate, how to check the actual bandwidth we getting from ISP against 1 Mbps. We have solarwinds monitoring tool in this i have configured the WAN interface for 1 mbps

I have 4 laptops (WiFi), 2 desktops (LAN), xbox (LAN), and dish receiver (LAN) that are all connected to the internet using the method between the brackets. Recently i am running out of bandwidth, and what i am looking for is a freeware that i can install in one of the computers that could tell me which IP or MAC address used how much internet.I have read several articles: some articles point me to softwares which only monitor the computer that they are installed. Other posts argued that such thing can only be done through the main router. I know my router doesn't have such feature. I use SMC router.

I'm going to combine 2 512 kbps ADSL line in my PC. i know that it would be much better to get a 1 MB ADSL connection...but the problem is where i live now there is not better speed than this! Well i have a PC with 2 LANs - 2 phone lines - 2 ADSL modems - as far as i learned from Google , by no means it is possible to combine them to have 1 MB data rate but it is possible for example IDM would works with one 512 and another program with another 512..!! And load balancing is the only solution for this which it needs a special routers ! it is somehow difficult for me to provide one ..!! so my question is :
1- Is there any other solution for combining this 2 lines?! I heard something about teaming.
2- Is it possible to use load balancing by software?
3- How about the efficiency and ping time?

ok i have setup a subnet on my uncles network on which i am running a domain with server 2008. i am using a dlink di 624 router and wanted to know if i upgraded to a 300mbps router would this increase the bandwidth within my network?i know i am limited to what i am receiving from my uncle who is also limited to what he is receiving from the ISP. im not worried about internet speed. i want to increase client to server speed for both lan and wireless.

We have a Cisco 3845 router and on the G0/0 interface we have our public switch with multiple public IP addresses (servers, routers, etc..) and on the S0/0 interface we have a DS3 Internet connection. I need to limit the bandwidth from the Internet (download) to one of the IP addresses on the G0/0 interface. I'm thinking of limiting to 256K and really need info with either a policy map or something equivalent.

I have multiple laptops and a PC in my house all connected to Verizon's wireless/wired modem/router.My laptop's bandwidth ranges from 7-20 Mbps, while the desktop cannot seem to rise about 1 or 2. The wireless card for the desktop was a USB Wireless G adapter, in the process of trying to figure out the problem, i replaced it with a b/g/n PCI card. This did NOT resolve my problem. So in a fit of desperation, I reformatted the Desktop, and Restored the modem/router to factory defaults (in that order) neither worked.

-I use a router and connect two pcs on it,they use internet at the same time.
Q:will the speed be 5mbps on each computer? if so,is there a way to make it 10mbps each while they are both using the internet at the same time?

I'm wondering if there is an easy way to monitor how much bandwidth is being consumed at any given moment for a home network.specifically, for the incoming/outgoing internet connection.My network is as thus:
DSL Modem -> Wifi Router (Linksys E4200v1 - PPPoE enabled here) -> Gigabit switch -> 2nd Wifi router (D-Link DIR-815 - DHCP disabled, repeats same SSID and password)
Most devices are connected directly into the switch, with one computer hard-plugged into the DIR-815 (I will eventually change this, as the 815 only has 10/100 ports).Basically, I want to easily be able to check how much up/down data is being sent for my internet connection. This means that I cannot use a program on a computer (I've used DL Meter before. Works great, but limited to a single computer).
The Linksys E4200v1 is using standard firmware, but I'm not opposed to loading DD-WRT onto it (was the original plan anyway, just never got around to it), if DD-WRT has this capability.Nice to have feature: Ability to see which devices are consuming what part of the bandwidth. Not necessary, but would be a cool feature.Alternatively, if there is a cheap (like $100 or less deal) box that can interface, say, between the E4200 and the switch, that can do this, that would work as well.

If there is something that cant control the bandwidth of our internet.
The problem is that one person is constantly hogging our internet by downloading and such and making it impossible to play games.
So is there anything that can make it so he cant use that much bandwidth so we can play without constant lag?

I Just got FIOS internet at Home with 43 Mbps down and 32 up (measured speed). I replaced the included router with my old reliable RV042 (V1) VPN router that I used with my old service in NY LI. This has been working very stable for week or two, but I use my old 042 to remote desktop via VPN from my work, that was limited to maybe 9-10 Mbps (Home to office) way down from the 32 up I have now (the office has 80Mbps down). So I researched that the RV220W had a VPN speed that was much faster and I ordered one that I am trying this weekend.Out of the box, I plugged accessed and just clone the MAC at the WAN port to match the replaced FIOS router. Power cycle and surprise, no IP from FIOS!. After trying a number of things, I gave up and updated the firmware to the last 1.0.2.4, and that fixed this. I still need to clone the MAC to void calling Verizon FIOS, but at least I get IPs and Internet with no trouble.Next, I configured a couple forwards for two web servers. I found about the bug in this same forum and just used the rules instead. Working good so far.
So now I test WAN bandwidths, and I found all kind of trouble. With the old RV042 and similarly to the included Verizon router I can do steadily 43d/32u. Especially at night is quite stable in these numbers. When I went and move the cables to the RV220W (exact same set up) the speed went all over the map from 4d/8u to 43d/25u. If I power cycle the box, things tend to be stable again around 43d/25u. So, after a while being stable in these numbers I start trying things to improve the 25u that should be around 32u, and recover the missing 7 mbps. Not much I can think, so I just randomly enabled the QoS settings trying to reserve full BW for my tests, and I found just that enabling WAN QoS, and nothing else, no profiles or changes in the Priority Settings, I go up to 30u consistently over a number of tests. This do not affect the down speed that is stable at 43 mbps. The surprising thing, is why this affect to the up speed when nothing else is going on in my network? and also where are the other 2 Mbps to complete the 32 Mbps that I can do with the RV042 (V1) or the cheap included router? In my opinion, if I don't use QoS, I should get full bandwidth to whatever application/computer that requests so, period.

how can I configure a Catalyst 3750, which interface is patched on the ISP router (internet uplink bandwidth = 20Mbps with) to allow all active users are sharing the bandwidth (either 5, 50, 100, user simultaneously..in internet surfing. right now it's like when a user starts a larger download that it uses the bulk of the bandwidth, and other users can reach all remaining extremely slow access times.

I have a 100mb conection and regularly get 90mb plus speed when conected direct to the modem. If I conect via the E4200 I only get 50mb ? I have tried disabling the firewall and QOS but this has had no effect. I am using a wired conection and the latest firmware. Its almost as the E4200 is capped at 50mb throughput.
