I plan on starting a high speed LAN for my Gaming LAN party's. We send 100's of GB of data over our LAN networking when we do this, so i need a good switch that can handle the stress of the massive data transfers. It needs to be a gigabit switch and at least 8 RJ45 ports.or is there a different one i should get all together? i cant spend a butt load. url...
View 3 RepliesSo a BT home hub is a very cheap router, so it seems. And - if you connect a quite a lot of eq to this router, it starts crashing. "It can't handle the traffic.". But what does that mean? Why can it handle the traffic for a while and after a few days it can't anymore. And lets say - some of the eq doesn't really work on the external network, it works on the internal network, and it doesn't need the internet to work for proper functionality. So - what is important then? Which specifications are the important ones?
View 2 Replies View RelatedI have a bandwidth-intensive video conferencing device connected to a router. I have forwarded all the necessary ports to the device (and I have even tried DMZ) but the device is unable to connect to some servers due to "NAT issues". The device uses lots of ports simultaneously to connect and I am wondering maybe possibly the router can not handle the number of open ports. The ISP only blocks port 25 which the device does not use. Could it be that the ISP limits the number of ports that are in use? Or maybe the ISP limits the amount of bandwidth that can pass through certain ports?
View 4 Replies View RelatedI am a new network admin at my company, and I am investigating a problem that is on a network designed by someone no longer here. So, I can't ask why things were set up the way they were. Anyway, here's the issue:
We have 50Mbps WAN connections between locations. The WAN devices are 3750s, but the port plugged into the providers network is a layer 3 port. Config is below for one of the ports: [code]
So, these are Gig ports, but our service provider limits to 50Mbps. When we do a data transfer, we can't exceed about 20Mbps total on the circuit. The data transfers at maximum 15-16Mbps.
I'm not familiar with QoS. I've tried to read more about SRR, but don't understand it well enough to know. Are the QoS settings creating this restriction? Our provider swears that the bandwidth is allocated and its not being choked on their end. I have not taken off the QoS config to test it that way because I'm not 100% sure if its needed and serving some purpose. I don't want to break something in order to fix this.
Is the QoS causing this? Do I need to put a bandwidth statement on the port? Should we be using routers and LLQ?
This is a new RV180 install. FTP data transfers fail in binary mode. By fail I mean the first packet sent, isn't accepted (acknowledged?) by the FTP server (Network Solutions, Passive Mode), . If I pull the router and replace it with an old D link router or 5th gen Apple Airport Extreme, everything else the same, it works OK. I lack the tools and knowledge to proceed beyond this point.

All seems to function properly: the clients are simple Android device and the connection appears solid.. We've a good roaming between access points (not seamless of course but is ok) and no particalur problems, also because the network is used to drive very LOW data (no internet): the clients opens a tcp connection to the server and sends only a keep alive packets over this connection.. Then sometime the server send a very small amount of data (some byte) to activate the display of the device and show a question.. the clients reply with some other byte of data and so on.. During an event of 3/4 hour we can do this 12/14 times, so the network load is nearly 0....
Last night the system suddenly stopped working: ALL clients (300) lost connection from their access points at the same time! How this can happens? The only reason that I can imagine is a power loss on the switch...

My basic idea is that everybody can share their data and the data is searchable from one common interface( Web interface is better option, if possible).

View 2 Replies View RelatedI am hoping to have my internal data NOT sent via the router.I'm trying to figure out if data from the Windows PC to the Ubuntu PC goes via the N750 AND the router or just the N750.It should be noted that the N750 is set up as an access point with DHCP/NAT disabled. I have read that switches (and I assume this "access point") can store the MAC Addresses of computers to cut out the router, but I'm not sure how to make sure that that's happening.
View 2 Replies View RelatedI should set up a network for a little enterprise.The requirements can be summarized as follows:
- All the "business" softwares have to be stored in a single computer (let's call it "the server"). The other computers (in this case there should be at most 2 or 3 computers) can execute these softwares through the server. So there are no local copies of those softwares on clients, only on the server.
- The main computer (the server) shares also a printer.
- All the computers in the network, are interconnected through a single wi-fi modem/router. Some of them are connected through the wi-fi interface and others through an ethernet cable.
the server, in order to perform some special procedures, has to connect to a special modem which connects it to a remote private network. In order to do so, the server disconnects from the local enterprise network because Windows does not allow me to stay connected to more than one network at the same time.The remote private network does not require to disconnect from any other network, it's just a constraint imposed by Windows.In the meantime, clients are not able to execute softwares anymore and cannot print anything.when the server is connected to the private network, it still needs to execute the "business" softwares.
Is it possible to keep the server connected to both the networks without denying the access to softwares, data and printers to anyone? If yes, how?If not, how can I design the topology of the network in order to share softwares and other data among all the computers (server and clients)? It's important that when the server connects to the private network every computer (including the server itself) can still access softwares, data and printers.
Is there a more detailed log or information from the router?I'm still having massive network variations, even with everything wire connected.

View 1 Replies View RelatedI am considering the RV180 as a wired router replacement to my current wireless and I can not find any user reviews, comments or ratings. I live in an area with a very poor wireless reception for our Sprint Cell phones (Still under contract) and I have a Sprint Airave which boosts the wireless signal for the cell phones. The Airave transmits on a 2.4Ghz band and it is stepping on my Internet wireless signal causing poor reception thought my 2-story house.
Due to this problem, I am considering installing a business class network with a router, PoE switch, and a strong Access Point. My house is pre-wired for with CAT5 wiring. I have looked at the EnGenuis EAP-350 Access Point (800Mw and 29dBm gain and PoE), The RV180 Gigabit Router, and the Cisco SD208P 8-port gigabit switch with 4 port PoE support for the Access Point. The switch will be located in a wall junction box so I need a switch with minimal ventilation requirements. Is the RV180 and SD208P the right choice to integrate in my network?
My experience with Linksys and Cisco products have been Great so I would like to stay with Cisco. I have looked at a competitors router (Netgear FVS318G-100) but the user reviews were very poor. I am not sure if I need a managed switch or not, as I will have one primary laptop running during the day and up to 3 other computes(2 laptops & 1 desktop), a wireless tablet (android), and a Xbox (wired connection) for the family (of course not all running at the same time).

View 1 Replies View RelatedWe're looking for Cisco switches with the following attributes to serve as the core switches in a production network:1U (or close), fixed config20 or more 1GbE copper ports4 or more 1/10GbE fiber ports (SFP+)Not ridiculously expensive So far the closest fit we've found for these requirements is the SG500X-24. However, since the SG500X-24 is a "small business" switch we're concerned that the reliability may not be up to the levels of Cisco's enterprise switches, the support level may not be sufficient, the 12MB packet buffer may not be enough to support wire-speed operation (or efficient communication between hosts on 1GbE and 10GbE ports), and so on. But in looking through Cisco's entire current switch line (a daunting task...) this seems to be the switch that best fits the specifications above. So, some more appropriate switch that fits the listed requirements?s why the SG500X-24 would be a poor choice for a production network? Have you had positive experiences with using the SG500X-24 as a mission-critical switch?

View 2 Replies View RelatedMy 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.
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?

View 1 Replies View RelatedI 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.
how to measure the router or swith capacity?
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"???

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?
