you have a Cable Modem and are paying for 30MB/sec download or better service, but the network connection on the cable modem is only 10/100; all very common today.Your network connection is showing it's connected at 100 (computer - router - cable modem)....now on the technical side, remember that a 100 MB network connection can only transfer data at a maximum rate of 12.5 MB/sec (not something the normal home user knows or even thinks about).So here's the question; why would you pay for 30MB/sec download speeds when the cable modem itself can only transfer (in theory) 12.5MB/sec to you over the network?
I have a Cisco WRVS4400N on the latest firmware and I have just had my Virgin internet connection upgraded to the 100Mb. Once i thought it was upgraded i checked with a broadband speed test and it came back as 15Mb download and 5Mb upload. Before i rang Virgin i thought i'd check with a direct connection from my pc straight to the modem. Ran the speed test and it came back as 100Mb download and 5Mb upload. I thought the best thing to do is restore my settings back to factory and its still the same.
Just upgraded to the 30mb cable modem. When I hook my laptop up via cat5 and run a test I get like 28mbps. Via my router I only get like 11mbps tops. What do I need to do to get more speed via router?
I have a Cisco 881 (without wifi model) connected to a 100Mb unmanaged switch and a cable modem with a 120Mb down, 10Mb up connection. When I connect the modem directly to my laptop, I can reach the 120Mb/s down and 10Mb/s upload speed. When I connect the modem to the 881, the max download is about 30Mb/s. Upstream 10Mb is no problem. I've been trying to change the duplex and speed settings on the FastEthernet4 interface, but this has only a worsening effect. I should be able to get about 100Mb/s (since switch is only 100) right?
Why does my F5D5230 Router restrict my network connection speed ? I have a 30 mb connection to my cable modem when connected to my computer,but when I install the router my connection speed drops to 5mb.
I want to know which router can be used on 100mb cable connectionThe router will be using the connection from cable modem on bridge mode/modem mode with eth to routerI kind of have a idea looking at performance ratings but ppl have mixed opinions when you enable NAT and ACLs etc etc285129013825.
So I recently got a new computer today and it won't let me use my 100mbps of internet bandwidth. (Asus Sabertooth Z77 with an Intel 82579v gigabit lan controller) I noticed that at the LAN connection properties>Properties>Configure>Link Speed tab the 'Speed and Duplex' option was on Auto Negotiation and it was only accepting (or supporting) the 10mbps Full Duplex. When I switched it to 100mbps Full Duplex it would mark my connection icon with a red cross and when I clicked diagnose it said "Please connect your ethernet cable or your cable might be broken". So I tested my internet speed with that same cable on a different computer (laptop) and it worked with 40Mbps, so I don't think the cable is broken. Also I just recently downloaded some drivers but one was specifically for the Intel LAN controller but I'm a total noob for all of this computer stuff I don't know if it messed it up or something. Is it the motherboard that's not working correctly?
When I create a service object or group and add the object to a new rule it never works.I mean the traffic match not the rule. I see not hits.I placed the rule on top of my access list to check if I do somethink wrong but it is not working. When I place only a service for example tcp/23 it is working.
I'm looking into upgrading my WAN link to 100Mb via Fast Ethernet link. I'm waiting to hear from ISP about what exact technology they use, but according to my manager they will be coming in over fiber and then terminate to copper. I currently have 2811 in production with two T1 cards bundled together. 2811 has basic configuration with only 2 ACLs. I have ASA 5510 for NAT, Ipsec and other services. What router or networking device (layer 3 switch, such as 3560G perhaps??) should I use to accomodate 100Mb link? It seems that 2811 will not handle that kind of bandwith..In short the max recommended bandwidth limits for the 28xx series are as follows:
2801--2 Mbps 2811-4 Mbps 2821-8 Mbps 2851-12 Mbps
I don't want to create a bottleneck and am looking for appropiate solution to accomodate 100Mb link. Also, could ASA 5510 become a bottleneck in my scenario?According to Cisco docs ASA5510 can handle 300Mbps of firewall througput, but I'm not sure how it'd work in production...
if i plug a cisco 880 router in to a 100MB WAN Ethernet circuit what throughput will i get? on cisco site it says 25mb/sec but if it is Ethernet shouldn't it be done in hardware and get the full 100mb/sec?
I know that a 1841 plugged in to a 40MB WAN circuit can match that speed but Cisco site say it only can do E1 speed.
I have three ESW-540-24 10/100/1000 Switches in a small school environment
1. ESW performs as a server switch for out small cluster of VMWare ESXi Hosts and iSCSI SAN with a link-aggregation/lacp/etherchannel connection to the backbone switch, and a Link-Aggregated Connection to the thrid ESW switch via a multimode optic fibre link to a near-site backup and DR location
2. The second ESW acting as network backbone links back to the server switch and our older LinksysSRW224G4 (four SRW224G4s) switches using Aggregated Links / LACP to reduce bandwidth contention and allow for link redundancy
3. The third ESW as mentioned previously is at the backup DR location linked back to Switch 1
When using Single 1GB links between these three switches I can almost saturate the 1GB link (80-95% utilisation) as soon as link aggregation is configured by bonding 2x 1GB links together to form an etherchannel link utilisation will not exceed 100MB (network monitor graph on a server/ workstation runs flat at 10% utilisation) I have tested this multiple times useing large file transfers accross our SANs (which have high enough throughput to saturate links) and can confirm that performance degradation occurs as soon as an etherchannel is configured on the same ports (regardless of manually setting admin speed and duplex of copper ports etc) all indicators specify that ports are running at 1GB even though throughput REDUCES by 90%.
We are not running the latest firmware yet (2.0.3), however I have read the release notes for newer versions (2.1.16 and 2.1.19) and there is no indication of a fix for etherchannel/lacp performance issues.
We have a situation where services are stopped on the real servers. The probes fail and we confirm the services are not running on the server. We cannot access the ports from the ACE directly. We can still however acces the VIP on the TCP port (L4 VIP class-map). So we can still telnet to the VIP on the port from thr Client side of the network.This is on ACE 20 Modules deployed in Routed mode. The version of software is A2(3.3).
Tried removing multi-match and loadbalance policies as well as class-map and re-applying then re-appyling the service policy to interface. Same behavior,This is a problem at another level as some services are being monitored by GSS via TCP keep-Alive and this obviuosly causes a problem as the service then never goes off-line.
My ADSL light switches off randomly during downloading a 100mb file. I just cannot complete the download. This has been happening ever since I switched my router to a wireless iBall Baton 150M.
I am assuming, that the slowest component on a network determines the connect speed? I am having a small network with 4 pcs and 2 of them show 1GB connect speed while the other 2 show 100MB. What would cause 2 units to run at the 100MB speed on a Gigabyte-Switch and Router?
Is there a big difference in operating AP's when they are uplinked at 100mb vs 1000mb? We have 2 "main" offices that have AP's that are all connected to our access switches at 100mb. Recently with the addition of mobile devices, phones, etc we are seeing some issues. Today, we had a meeting room that had 20+ people connected to one AP and they started seeing issues of people getting disconncted or unable to connect.Just wondering if the uplink could have anything to do with this, or if we are just over subscribing the APs?
I have a c3560 switch that has two gig fiber modules in it. I need to uplink fiber to one of these at 100mb. This is because this port will be rate limited to 20mb and 10 percent is the lowest you can go with the rate limiting command. Is there a 100mb fiber module i can insert in the 3560
4402's been running quite happily until recently. I have 11 wlan's configured, but only 5 are enabled at this moment in time.
There are 26ap's connected to the 4402, a mixture of 1130's and 1142's. The memory error in the subject is popping up quite frequently.
No reference I can find on this forum or other Cisco.com.

I just want to know if FTP service can be done without internet? I want to setup my file transfer locally just w/n the campus.. All resources will be centralized in one server..
Can I have 2 Internet providers?I've been with Orange broadband for a few months and it's been unusably slow, so we're cancelling the contract and changing to Sky. Orange are making us trouble-shoot before this can happen, so the preference would be to install Sky, leave the Orange router unplugged and ignore it until the contract ends. Is this realistic? I know both couldn't use the line at the same time, but could we just unplug our Orange router or would it create slow down or not work at all?
I live in an apartment and I am forced to only use the apartment's internet service to go online.There are two ways to access the apartments network; via ethernet port or wifi. Once im connected and try to browse, I will first be taken an http login page to enter my username and password.The problem with this is I can only use the username and password for one computer at a time. Trying to get my second laptop to access the web using the same user and password will give me an error saying it is currently being used. As I have two laptops (work and personal), I would like to share the internet connection using a device that will allow either or both machines to connect simutaneously. What device will I need? A router, modem/router, access point, etc? And what configurations should I try?
I have Windows 2008 server running isa server with dedicated ip (which I take from my Internet Service Provider ISP) running my website, if my internet connection is down my website is not accessible from outside world.How can I switch to another ISP using same dedicated ip address when my ISP connection is down?
Our network administrator restricts all our new 1Gb switches to only 100Mb, to which he claims it will increase overall performance. Preventing devices from bottlenecking the network. (that is, only restricting the main switch ports, not the uplinks)For example we have a new building with 2x WS-C2960S-48TS-L connected together with FlexJack and then a 1Gb Fiber connection back to our core switch.
This building is on it's own subnet and there is little broadcast traffic. I don't see the point other than it hinders the potential speed we could use. Labs are set up in this building and 1Gb is MUCH faster when it comes to imaging and software deployment.
Is this a wired or wireless connection issue? Both Who is your Internet Service Provider (ISP)? Comcast..What type of Broadband connection are you using? Cable..What is the exact Make and Model of your Modem, Router or Modem/Router Combo - (Main)Netgear WNR3700v2 / WNR2000v3(secondary) My current setup is the 3700 router is taking the internet from the modem cat5e and spewing the wireless. I would like to have the secondary router use the wireless from router 1 as the internet source and push the internet out of the 4 hardline ports so I can plug my upstairs xbox 360 into the router via cat5e. I'm just kinda new to this and still learning so I'm not sure how to configure the router to do this. I can get into the settings of the router just fine but finding the right settings to tweak is a little difficult.
I fought with trying to hang two old BEFSR41 routers on an incoming TWC cable internet. I have a couple of streams going out and one coming in... and I think there are some collissions going on that cause little Urps in the streams. I thought I could put them on two different subnets. Ha. No luck at all so far. The scheme they gave me used a fixed IP and a subnet of 255.255.255.252... now I think I understand why TWC assigned a subnet of 255....252 - so I could only use ONE router. Their little toy is still routing, mine does it's thing.. that's it. In order to add another router and a totally different group of PC's on the same bandwidth... I'd have to get into their box and change the subnet scheme to something more open.. 255.....248, or maybe back down to 255...255.0 I guess..
I plug it in and connect the computer to it and expect it to work. And it has been doing that without any problems until I bought an iPhone and brought it into the house. I thought it was a fluke, but the day I brought the phone in, my computer started intermittently losing it's connection. If I turn the phone off, the connection comes back on. But what seems really odd to me is that if I right click on the wireless network icon it says I am connected and the strength of the signal is excellent. But then it says no internet access.
I have a wired broadband connection with a modem. My internet service provider does not have Wi-Fi. Can I convert it myself into wi-fi by connecting it to a router. If possible how?
