My cable modem and router are in a closet. From there, wires run through the house to multiple locations. One of the locations has had a wireless access point (WAP) installed which has worked flawlessly. I want to put another device at that location that doesn't have wireless capability, so I tried to connect a switch. The switch does not connect. When I disconnect the cable from the WAP and plug it into the switch, the light on the switch port that would indicate a connection does not come on. When I then connect the WAP to another port on the switch, the light on its port does come on but it does not see the router. I've tried multiple cables (I even tried a crossover cable) and I've tried a second switch with the same result. When I plug back into the WAP, it works fine again. The switch works fine at other locations in the house.
One more thing - When I bought the house, the wire to this particular location was unterminated. I had never done any wiring before but I decided to try to do this myself. So, I read up on the process and bought the necessary tools. When I stripped the wires, I found that the twisted pairs were not just twisted (as they were in the patch cable I practiced on) but each pair was in a single strand of insulation (I'm not sure exactly how to describe this but there were four strands of plastic, each with two wires packaged inside.) I didn't know how to separate the two wires that were packaged together so I wired the connectors with all four color - color/white pairs next to each other. I know that's not the standard. But from what I read, as long as I wired both ends of the cable the same way, everything should work. And in fact, it did for connecting the WAP.
We have a legacy client/server application, an OCR system. The server runs on Windows 2003 R2. We have client machines running happily on Windows XP.We have for a while had problems with getting the clients to run on Windows 7. Some machines wouldn't work, others worked intermittently, one worked consistently. By a process of elimination I discovered that the one working consitently was on a desk where we had put a small 8 port 3Com gigabit switch on the desk to give us more network ports. If I move this switch to any other desk to one of the non-working clients and connect them using the same uplink but going through the desktop switch they start working.The XP clients work fine using any of the network switches. None of the 100+ devices on our network (desktops, laptops, VoIP phones, printers etc) are showing any other signs of network issues, only this OCR application. The application was last updated in 2004, so was not designed for Vista or 7, essentially the vendor is no longer updating it, but say that as far as they are aware it works with Windows 7.why adding a 3Com 3c1670800B switch between the client and the rest of the network should make the application work with Windows 7. Whilst I have a workaround for the problem I'm uneasy that I don't understand the root cause, and if I was to press ahead and move the client machines to Win7, the whole system depends on a single piece of kit that's now discontinued and I only have one of. It all seems pretty counter-intuitive to me that an application should be sensitive to low level network hardware.
reinstalled my windows 7 and it doesn't have the network adapter drivers,so i go and dowloand the drivers i install and it still says no drivers installed, and yes i got the right driver,i tryed everything just cant get it working
My laptop is able to connect to the wireless router in my home, but the browser will never load a page, status is shown "connected". However, when I try on other laptops, they are able to surf the net. I have tried using my laptop at my friend's place with a different wireless router and it works at his place as I was able to surf the internet through my wireless! So, I've tried resetting my personal modem to factory default and it still doesn't work.
Im looking to create a home network with a wireless router.I have three machines, one computer is downstairs connected to the router with an ethernet cable, my other two machines are upstairs and connet to the internet wirelessly through the same router downstairs.I want to be able to connect to my upstairs computer with my laptop and access my files, i have an external hard drive connect to my computer and want to be able to back up to it from my laptop without removing cables.All three machines are running windows 7, the homegroup doesn't seem to work?
I just recently bought a Telewell Wlan AP wireless access point and my problem is that I can't connect to the internet with Lan, hence can't get connection on my desktop. My laptop however works fine with wlan.
There's a wall socket which connects to a bigger student local network, I can connect my desktop to it directly and it works so there seems to be nothing wrong with my computer. I've had 2 routers before this, another Telewell that worked flawlessly and a Buffalo that cut the connection every now and then but didn't have this kind of problem.
I have the router plugged into the wall, set to get a dynamic ip (as it should be) and it does find Wan-side ip-address and dns-servers, as I could connect through wifi. So there doesn't seem to be a problem with that either. But for some reason Lan doesn't work. I can access the router through Lan, dhcp is on and I can see my desktop on the routers client list.
I am running XP Pro SP2 Ver. 2002 on my laptop.,i use the wifi connection very well. But when i plug the rj45 cable in from the modem,the LAN icon says Little or no connection.
hen its wireless, it has no problems with the internet, everything works fine.But when its wired, webpages will still load, but youtube videos wont work, anything that consists of streaming doesn't work, and he cant even useI have connected other laptops to the same cord and there is no problems. so i know its not the cord and i imagine its not the router since everything still works fine with other computers.
my internet works normally during daytime but starts to disconnect and reconnect every few minutes at around 11pm. I've tried restarting my modem but to no avail. My home telephone line is not working when my internet starts disconnecting and it starts working during daytime. My modem is connected to the telephone.
I have a directly connected server behind the ASA and I can ping the server without a problem.
The VPN client reports packets being encrypted and decrypted
However when I try to RDP to the server the encyrpted packets keep incrementing but the decrypted packets do not.
I am also not seeing any RDP traffic hit the server (verified by ethereal)
I have done a packet tracer and it suceeds but ends with an IP spoof which I believe is correct as it is vpn traffic and not actually being encrypted.
This is the debug from the RDP session, I am confused by a Denied ICMP on line 2 as I am able to ping the server?
%ASA-6-302013: Built inbound TCP connection 88193 for external:172.16.24.4/50984 (172.16.24.4/50984) to internal:192.168.100.146/3389 (192.168.100.146/3389) (roger_ssl) %ASA-4-313004: Denied ICMP type=0, from laddr 172.16.24.4 on interface external to 192.168.100.146: no matching session
[Code].....
The only logical bit to this is flow closed by inspection? Does this mean the server has not responded?
And the decrypt packets not increasing when trying to RDP Does this mean that I have reached the end of my ASA knowledge on this one!
new to networking, I can not fully understand concepts like VLAN, so I would like to know whether it is possible to have a a few VLANs without a switch but over a bridge (created under linux - connecting a few virtual machines).
I have been using my laptop since a year now and yesterday suddenly my internet stopped working. On top of the connectivity bar a yellow sign appeared. Now my internet status is "No internet access" but when i connect my ethernet cable the internet starts working and i can see the "Internet access" status. I have re-installed my wi-fi driver too from the orignal CD that i got with my laptop, but still no luck also i did not install anything in past 1 week and the only anti-virus i have is Avast (tried disabling it too). I plugged out the cables from my router and plugged them again but that dint work too. There are 2 other laptops (running on windows 7 just like mine) on which the wifi connection is working but on mine it is not working.
I have a ASA5520 with 4 Port channel interfaces and ASA Version 8.4.(2). There are many vlan interfaces but in the DMZ I have one Server who has a Static NAT to all other interfaces.
Why the first ping works and the others doesn´t work?
So I am contemplating the setup for the network in my new home, how to connect 24+ ethernet ports in the house to a single network. I was thinking of getting a nice dual-band wireless router, but those usually only come with 4 or so lan ports. How would I then utilize a large 24- or 48-port switch to connect everything to the router?
I need remote access to certain programs on my home PC but I just cannot get it to work.
Program:- webcamXP
When I set the programs port preferences (i.e. port 8087), I can connect with"127.0.0.1:8087" and webcamXP work fine. But when I replace the localhost with my external IP (lets say 79.149.114.227, so that would be "http://79.149.114.227:8087".I tried port forwarding: I have added the port to my NAT in the router's setting so it should be fine, but it is not (numbers are fictual of course):
external port start 8085, external port end 8089, protocol TCP/UDP, internal port start 8085, internal port end 8089, server IP address 192.168.1.215)
I also tried disabling AVG Internet Security 2011's firewall temporarily just to check it it was blocking it, but got the same result.I checked if Windows own firewall was on, but it is off.I cannot find any setting in the router's own configuration screen to disable any build in (router's) firewall (if it has any).
I try connecting via ethernet cable and it doesn't seem to work until the administrator of the network (my brother) comes home and then turns his computer on and starts using it. However, if i switch to a wireless adapter it sometimes works (like right now) even when my brother is not using the internet. Also, i tried to connect via wifi on my macbook pro to the same server and it used to work flawlessly 100% of the time, now i can only connect once in a while for short periods of times.
I'm trying to set up a wireless network for my parents. I have a Belkin Play N600 router (model F7D8302) that I'm trying to hook up to an Acer desktop running Vista. The modem is a Siemens Speed stream 4100. I have a cable going from the ethernet port of the modem to the modem port on the router. The pc is connected to one of the other four ports in the router. The wireless works fine, but I can't get the wired connection on the desktop working. The Internet light on the modem is not on, but the modem works fine when connected directly to the pc. I've tried power cycling and resetting everything, but it's still not working.
I have a win7 desktop upstairs with all of my media on it.I also have a winXP laptop that I would like to use as a media center running xbmc connected to my tv downstairs.I have set up a workgroup so my laptop can access the media stored on my desktop and everything works great when they are both hardwired to my router (Linksys E3000).However, as soon as I unplug my laptop from my router and switch to the wireless connection I can no longer ping my desktop or access the shared folder (internet still works fine on the laptop, it just cant see my desktop anymore).If I plug it back in to the router, everything works again.
The exact error message I get when I try to access the shared folder is "\INFINITYMedia is not accessable. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. [code]
About 6 months ago I bought a new router (Linksys E1000 v2.1) which worked great right out of the box. A couple months later I tried to setup a home network so that my two laptops could access a shared drive on my wired desktop, but for some reason they didn't show up as being on the same network. All computers involved are running Windows 7 if that matters.
Upon a recommendation from I friend I put DD-WRT on the router and it worked fine. Setup MAC filtering and WPA2 Personal security. This worked fine for about 4 months until today.
When I got home from work today I noticed my laptop wouldn't pull up any web pages, but it said it was connected. Then I noticed my iPhone wasn't connected either. I restarted my laptop and then it wouldn't connect to the wireless either (I could see the wireless, but I would get a Could not Connect error when I tried to connect to it).
I went to my desktop and it is working just fine, it is plugged into the back of the router. I also have an AT&T MicroCell (cell phone booster) that is plugged in to the back of the router and it works fine too.
I removed the encryption and MAC filtering. I then reset to factory (or "factory" DD-WRT) and now the wireless works, but it is MUCH slower than my desktop. I ran a speedtest on my desktop and got 12 Mbps down and 1 Mbps up. On my laptop, I get 0.03 Mbps down and 0.25 Mbps up.
Region : India Model : TL-MR3420 Hardware Version : V1 Firmware Version : 3.12.21 Build 120523 Rel.37880n ISP : Reliance
I've just set up a MR3420. It works fine in "WAN only" mode and provides access via our ADSL modem. It also works fine in "3G only" mode and provides access via a Reliance Netconnect+ USB modem (a Huawei E150 I think). I updated the firmware to the latest version in order to get it to work with the USB modem.
The problem I have is that when I set it to "3G preferred" it doesn't seem to connect over 3G. I can see it tries to connect but then fails and then WAN takes over. The connect and disconnect options are greyed out on the 3G page so I am unable to manually get it to retry. I've tried leaving it for a long time but it doesn't seem to connect over 3G ever. I've tried setting 3G to connect on demand and connect automatically but both behave the same.
I am renovation my own house, and I have started to hard wire for the network/s, but I am also trying to incorporate so much more than any previous “wireless” setup I have had, well I am a bit confused to say the least.I would like to set up a home network and media server system which includes:Internet browsing (multiple rooms and wireless) File sharing, printer sharing, scanner etc Music/Video sharing/streaming, TV etc.I have started wiring (we are renovating) with Cat5e, and have just replaced the old POTS (telephone) wiring with Cat5e and taken the individual telephone wires (including the incoming telephone cable) back to one central connection unit in a network patch panel. This has improved the speed of my DSL download connection speed from 1.2mbs to 6.2mbs. unreal!, so that did get me a bit fired up!I am currently wiring data points (Cat5es from each room) back to the same panel, but to be honest I am not really sure where to go from there! Also, I have wired Sat cables back to this point ready to be connected to sat TV (dish) in case if we get it. This patch panel is in a small passageway that goes through to the garage from the house. It is conveniently located next to the mains board which I have just replaced. My original idea was to put any extra needed equipment in the same location, but looking at it, I think that I may have to think again, for there is little room. I have found a small alcove in the upstairs games room which has a shelf, and which could take any hardware, also it will be dust free (unlike the place leading to the garage). I can run as many cables as needed from this location to the patch panel, but obviously I would like to know how many, as I am not familiar with networking on this scale, my only other experience being wireless setups. For example, would the switch need to be located where the patch panel is, or else can it be on the shelf with the other stuff? (away from the panel), and the existing D-link 4 port router?? is this no longer required?Im presuming i will need an old PC or some sort of media storage device here too... no ideas with this either. Have tried asking three different computer stores, got three different answers...?!
Have I dropped a clanger wiring to the passageway, when infact any server/switch or whatever wont be in the same location?Also, I am planning on getting a MAC book, and would like to use this on the system sometimes (might not be relevant), just thought to mention. And, I was thinking of trying Linux, as I am fed up with all the windows problems. But not sure if that is a good idea either.We have TVs in the (when its finished) media room, also three other areas, which I would like to get connected so that they will be able to get either TV or watch a film from storage wow this is getting complicated and if it matters I do have a PS3, which we only really bought to use as a TV storage system/recorder.
Ex: Actually my problem is, i'm using Dlink 8 port switch, and 40 computers connected indirectly to that switch, few times getting issues like packet drops, internet connecting & disconnecting etc. so i want to know either the switch is capable or not.
As we know when multiple PCs share same link"line" they will need multiple access protocol like CSMA/CD to protected from collision,,share link like "bus topology" need multiple access protocol "CSMA/CD" but in star topology"switch not hub" PC0 connect to port0 ,,PC1 connect to port1 PCn connect to portn then every PC connect to separate port ,, and the switch mange the network"by using MAC" then why we need to used CSMA/CD in star topology"switch"???
I have Zyxel Modem configured in bridged mode with static IP from ISP. I want to connect multiple PCs to modem via switch so that each PC use the same configured Public IP address to use the internet. For this (generally) I would need to configure NAT for that IP. But I want to know that will it work under bridged mode or not?
I have 24 port switch which is already connected to internet through static IP. Now I want to use a router as a wireless device to use internet. How do I connect router to switch?
Currently I have the modem into an apple airport extreme, this provides WiFi to the whole house + has a NAS drive connected to it...I have two x box's on the top floor of the house... One is currently wired to one of the airport extremes LAN ports...Now what I am trying to achieve - the second xbox is an old one so needs to be plugged in by cable too... (and I don't want two cables through the house). I have an old Netgear wpn824v2 router. Now so far I plugged the ethernet cable from airport x into one of the lan ports on the Netgear...Then both xboxs are wired into the netgear... The netgear has basically nothing setup on it - no security etc... ip address is on the same network as DHCP router.Netgear has upnp and dhcp disabled...Now stand alone one xbox at a time, the connection is actually faster than I have ever achieved, the full 50mb - but if i wire up my laptop to the netgear and use the internet at the same time the xbox lags like hell, so obviously not tried both xboxs together yet as it will just cause lag!
*modem* ----- wired to --------- -----airport extreme(provides WiFi to house)* ----- Wired to -- -----*NAS drive* --- AND--- -----*top floor to the second router - Netgear* ---wired to --- ----*2 Xbox's
looking to pick a good managed gigabit switch for my central media server implementation.I will have probably 10-12 tvs connected to this along with other things like ip pbx extensions, music streamers, ip cameras etc.Now I can imagine about 2-3 tvs simultaneously streaming HD quality movies. In that case, I am assuming I will need a minimum 150-200mbps throughput switch. Is my assumption wrong?I have been looking at some switches which seem nice and relatively inexpensive but the throughput is much lower than that.If I wouldnt need that kind of throughput then can you explain me how do I come up with my max limit.I initially thought that since its going to be a gigabit switch it would be able to handle that kind of traffic through all its port at once, but I guess thats not a correct assumption. Throughput is what reall dictates simultaneous maximum? Am I correct?
I began having a problem with streaming 1080p content from my media server to a router, wired to a switch that serves a few devices in my home theater (including a HTPC, my Boxee Box). Every 15 seconds movies have to buffer. After a while, I narrowed it down to the switch, since wiring the Boxee Box straight to the router caused the movies to run perfectly.Logically, I thought the switch was the problem, since I really made no changes on my network/DD-WRTRouter other than running a Minecraft server (which shutting that down made no difference in network performance). I ordered a brand new gigabit switch, same problem. Pinging the BoxeeBox returns 0 packet loss whether it's connected to the switch or router, but movies still play perfectly fine when directly connected to the router. Different cables didn't work.
I thought maybe the other devices on that switch were causing some sort of conflict.changed the BoxeeBox's static IP just in-case, unplugged every other device from the switch so that only the BoxeeBox and Router were connected to the switch. It worked fine! Yay! Tried a different cable, still worked fine. Great, I thought, so the problem was never my switch... plugged the old switch back in, then the problem returned. Ugh. Changed back to my new switch (each time power cycling all of the network devices) and the problem persisted, even with the SAME EXACT setup I just had a few minutes previously that worked fine. Tearing my hair out at this point.Since that moment I still haven't been able to reproduce a perfect stream unless the BoxeeBox is directly connected to the router. This doesn't make ANY sense as I had this setup running perfectly fine since November 2010. I am COMPLETELY out of ideas other than running multiple ethernet wires to that drop or running all the other devices on wireless.
Have a home network: 2 desktops & 2 printers wired to router (linksys e4200) Want to add nettalk for VOIP telephone service. All ports on the router are taken. What to do?
I have a E4200 v1, connected with a few PCs by ethernet ports and various devices by wifi. Now the wireless devices work perfectly but sometimes the PC via ethernet ports cannot connect to LAN and internet.
