Won't Recognize Connection With 100mb Full Duplex
Nov 6, 2012
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?

I have 100 mbps fiber connection. I bought 320N today I bought 320N and here is the problem:
We have a switch in the building. I am getting connection via CAT5. So I choosed "Use as WAN Port" from Ethernet settings. There is not much you can do here. I just used PPPoE and connected internet without any problem. The problem is I am only getting 32mbps. When I connect CAT5 cable directly to my computer I am getting 92mbps.
Maybe WAG320N is not establishing a full duplex connection.

I have C3750X with C3KX-NM-10G, and have-T SFP in slot 3 ( means it is not in SFP+ slot ).I need to set speed&duplex hard to 100/Full, but if I do the link goes down. I have the same settings on the other side, only IOS version is different.I tried other speeds - 10 and 1000, but no one works with Full. When I change duplex to Auto it works fine.The reason why I am doing this on C3KX-NM-10G is because I need to use NetFlow and cannot use the chassis' copper port. At the moment the ports are connected through a copper patch cord, but in full production there will be a radio link in between that requires 100M/Full to be set hard.I am trying to search for any document that would describe this limitation, but cannot find any. Also port capabilities do not indicate duplex could not be set to full:
show interfaces g1/1/3 capabilities
GigabitEthernet1/1/3
Model: WS-C3750X-48P
Type: 10/100/1000BaseTX SFP
Speed: 10,100,1000,10000,auto
Duplex: half,full,auto
Trunk encap. type: 802.1Q,ISL

I 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?

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.

I'm standing beside my wireless access point with my laptop. It shows full signal in my laptop but I cannot connect to internet. I clicked on the view available networks and then the SSID names, typed my network key, and clicked "connect". It keeps on connecting, connecting and finally disappears and WAN connection remains with crossed mark. But it shows full signal in laptop and I'm standing beside the WAP.

The main computer received a virus and I had to reinstall the operating system. When I did, however, all settings disappeared. The lights on the modem and router are fine, and the secondary computer has full access to the Internet. I also can use my Wii with the Internet. I tried setting up the router again but the main computer won't load the web-based configuration utility page. The secondary computer, however, can. I tried plugging the modem directly into the computer but the computer didn't seem to recognize it either. I bought a new router, thinking if I got software it would automatically set everything. However, the router I received came with zero software. I plugged it in and the computer still couldn't connect to the config page. I am at a loss as what else to do here.
My old router is a Motorola WR850G and my new one is a Netgear WR614 v9. Either would be fine to use, as long as I can get both computers to connect. The host computer has XP and the secondary Vista.

Due to the untimely demise of my old wireless adsl router (after an altercation with a destructive toddler), I've bought a new one.Connected it via cable to my laptop, & have set it all up through the wizard. When I'm connected via cable, I can access the internet perfectly well.However, if I try to connect using wireless, it can see the wireless router, asks for password, tells me I'm connected to the router - but it tells me that I'm in a local network only (can't find the internet). I've connected another laptop and a few smartphones to wireless, and they all work without any problem at all.I've done the usual take it all apart & start again, but it still comes back to the same problem.The only thing I wondered was that the new router is Wireless N, whereas the old laptop is a b/g - but we've got an older HTC smartphone that's only b/g and that doesn't have any problems.

My laptop is reading a full WiFi signal from my router. I am currently connected to the router via Ethernet on the same laptop. I've been reading tons of old threads to troubleshoot this. I'm at a loss. I have used this current networking hardware for more than a year without any problems. I do have a pretty old router but my iPod connects to the WiFi no problem at the moment. Here's what I've tried so far:
- soft reset of router
- power cycle modem and router
- removed saved network information from the laptop

I just moved into a new apartment and inherited a former roommates internet set up. Our router was infected with DNSchanger, so I sought to reset the router and update the firmware. I reset the router and it no longer recognized the internet connection. I can connect when plugged directly into the modem, but the router doesn't recognize the internet connection. Below is my ipconfig/all log:

I'm running Windows 7, and we have a dual-band router on 2.4ghz and 5.0ghz. My wireless LAN card is capable of picking up both frequencies, but will not even recognize the 5.0ghz connection, only the 2.4 one. I've checked all of the settings, "country codes", everything I can think of, but I can't seem to find a reason.

I have Virgin Media XXL broadband in the UK. I have Avast antivirus. Windows firewall is enabled and all security updates are up to date. I have a 50mbit virgin fiber optic broadband which is working fine on my flatmate's pc's. While making sure the internet wasn't being used my speedtest still returned around 1mbit with full signal strength. I have run speedtest on 3 pc's at the same time and 2 of them were over 30mbit while mine was still barely 1mbit. I am using an Edimax EW-7811Un nano usb adapter. From reviews I read that it should work great with Virgin. But for some reason it doesn't work well despite the full signal strength.

The power went out in the room where my desktop and router and modem and everything is located. The electrical outlet that all of those things were connected to suddenly stopped working so I had to relocate everything to the other electrical outlet in the room. Everything is working fine again, including the internet connection on my desktop, but now my laptop in the other room will not recognize my wireless connection. It gives me a list of available networks, but none of which are my own. Which makes no sense, as everything is working as normal on my desktop. I tried to "manually connect to a wireless network" by typing in the name and proper security type/encryption type and password, however it tells me a network called (my network name) already exists, and it says "use the existing network. Open the 'connect to a network' dialog so I can connect." or "choose a different name." When I choose the former option, the list of available networks pops up again but mine is not on there. And it should be, as I'm definitely in close range of my router.

I usually connect my PS3 to a switch which then goes to the BuT Home Hub and it works fine. However, I want to connect the PS3 directly to my Hub but when I plug it in to the Hub, it doesn't connect to the internet at all. Is there something I have to configure in order to get it to work?It is a PS3 160 GB Slim with Firmware 4.0.

When installing the DIR-615, router installs, but error msg that there is no internet connection. SmartConnect is plugged into the WAN and I have tried the ethernet cable to the computer in spots 1 & 2. Good connection when SmartConnect modem is connected to computer directly.615's Internet indicator will turn green for a while, usually less than a minute or two, then flashes, then may actually cause the routers status indicator to flash off, then back on. Like a reset.

Dell pc studio 450s will not recognize network connection after power outage. Have run diagnostic fix multiple times but to avail. I have roadrunner cable broadband connected to voyage router and then to wireless router. Wireless router and vonage works (as evidenced by this email using iPad)
Have already reset everything multiple times including unplugging modem and pc.
From what I understand the pc is getting gatewayaddress or does not recognize.

I have a WRT54GS V7 that I have been running for a few years now with no problems until today.My wife used the internet from her laptop through the day but this evening after she moved to the bedroom and booted up the laptop, she found there was no internet connection. I tried what I know in cases like these, unplugging the router or modem for brief periods of time to try and get things going again but to no avail. So I tried using the Easylink Advisor which basically suggested the same process.
At this point, my internet connection is coming in from the cable just fine. I have access on the desktop which is wired and works with no problems. The modem and router lights are both signaling that everything is fine but no wireless internet coming from the router.
Using the desktop I tried looking for some solutions and tried resetting the router. I ultimately called customer support but being out of warranty they wanted too much although she suggested that I needed to reconfigure the router since I had reset it. I followed the online instructions for reconfiguring but still have gotten nowhere.

Region : Others
Model : TL-WDR4300
Hardware Version : V1
Firmware Version : 3.13.23 Build 121225 Rel.37950n
ISP : UPC Hungary Ltd.
I can't able to recognize a system - all wifi clients lose connection. When this happens, the ping answer time rech the ~2000 times, then totally lose the connection, the SSID is dissapear - checking with my phone (android - wifi analyzer) and TL-WN822N USB wifi adapter (with the inSSIDer application). Meanwhile the cable clients and the WAN connections works fine, didn't experience anything.If I restart the wifi service with the hardware on/off button, it runs well for some time.This problem appeared when I used the two older official firmware too.
I tried the auto-chanel function width auto channel width, tried to manually set up one of the less interfered channels with both 20MHz and 40MHz channel width, but none of them bring the solution.The intresting thing is, if I change the router with an old D-Link DI-604, the signal is weak, but the wifi connection is stable, with the same TL-WN822N adapter.I tried to guarantee the router, but after two weeks, my reseller said, it looks ok, they - at the TP-Link service - didn't find anything.

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'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...
