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.
View 5 RepliesI have a Cisco 3725 running IOS 12.3. I have three WAN connections (2 x 100Mb and 1 x 2Mb serial) and I need to replace the 2Mb serial connection with a further 100Mb connection. However, I have not got any spare 100Mb sockets.My plan is to use a switch that supports VLANs, connect the three WAN connections to the switch, each in their own VLAN, then connect the switch to one port on the router, configuring the switch port as a trunk (so that it passes all three VLANs across the link) and configuring the router so that for that single Ethernet interface, it has three subinterfaces each configured for a VLAN that matches the VLAN used for the corresponding WAN connection.
I am a bit rusty on my IOS so I wanted to run this all past the community for feedback. [code] Any thoughts on whether or not that will work? Are there any commands from the original interface configurations that I CANNOT use when moving them to a subinterface? I'm thinking that the speed & duplex commands need to be removed?
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?
View 3 Replies View RelatedI 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.
View 7 Replies View RelatedI'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 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?
View 3 Replies View Relatedyou 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?
View 3 Replies View RelatedI 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.
I'm on a Virgin media 50 Meg connection currently connected via cable using the modem provided.I'm hoping to connect my PS3 to the internet using the router provided (dlink DIR-615) and I'm wondering if I'll still get the same speeds if I connect the cable through the router. I hear that the wireless data transfer won't be able to handle 50 Meg but if I attach a cable from the router to my PC will I still get the full 50?
View 1 Replies View RelatedIs 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?

View 1 Replies View RelatedOur 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.
The detected problem is the connection between my access point, router, or cable modem and the Internet is broken.The network gateway is accessible, but Windows couldn't receive network traffic from the Internet.All other devices (iPad, Xbox, android phone) have no problem connecting to the Internet.Desktop is the only one experiencing the connection issue.

When he got home he did scan disk (which I also did) and got it working after going into safe mode and doing system restore. He said an update had gotten through and messed things up. Anyhow, after he was on it a few hours last night, we lost connection. I figured the crazy weather was the culprit but it has been off all day. Our router is working and connecting but the adapter is not. Also our home phone says there is no line. We have unplugged everything several times, checked to make sure everything is in the right spots, I have even reset the router and rebooted the adapter. I uninstalled and restalled the adapter also. It is now telling me that "the connection between your access point, router, or cable modem and the Internet is broken". The only lights I have on the adapter are power, battery, DS and now the US light is blinking. The online and link lights are not on.

I can't get a new IP from my ISP when my Cable modem router(EPC3925) is set to router mode, i have tried factory restore, unplugged etc..but still no luck. It changes each time i reset it when i set it to bridged only mode but then i won't be able to connect other devices to it since it doesn't uses DHCP in bridged only mode. It changes back to the IP i had when i set it to router mode. I don't want to change my router settings to bridged only because it would disconnect the other devices in my house. Why my ISP assigns the same IP address when it's set to router mode but assigns different IPs when it's set to bridged only, how is this possible ?
