We have a NETGEAR ProSafe™ 802.11g Wireless VPN Firewall FVG318 set up at work with a static IP so we can do a Voice Over IP from our sales office.Everything works fine until I plug in a computer that is connected to our digital printer, then the PC stays on the internet for a while, then crashes the connection.Once I plug in the PC to the network, the rest of the network has issues.
View 4 RepliesI am dealing with three office networks, all three have the same conflict. The error messages I get all say there are two devices assigning ip addresses. As soon as I get the computers communicating with each other, two seem to crash overnight, I suspect due to the conflict. Here is the rundown on the networks. All are windows networks - the problem I am having is file sharing mostly and printing.
Network A: server OS is XP Pro - SP3, four workstations, XP Pro-SP3, Windstream DSL and Netgear Router. I have already bridged the router on this one, and it did not correct the conflict.
Network B: Server OS - Windows7 SP1, three workstations all XP Pro SP3, ISP is Clear (formerly clearwire). Router is the old wired Linksys befsr41 v4.
Network C: server OS - XP Pro SP2, ISP - Clear, three workstations - two are XP ProSP3 one is XP Pro SP2. I have had less trouble with this network, but I suspect the conflict exists here as well.
I have tried to get a static IP address from Windstream where I have had my worst problems, but cannot seem to get one. I suspect we have the least expensive service option possible, and are possibly using a service designed for home use as opposed to business, as someone told me recently that getting a static IP address can be expensive. Is this true? Currently all networks have DHCP enabled, and the routers are set up to use DHCP. My thoughts were to disable DHCP and assign ip addresses manually.
What I'm trying to go for is to make a Static IP so that I can forward my ports in order to play certain games. I have had my ports forwarded at one time with a different ISP (in the same area), however they used cable and the company I'm with now uses DSL. The company "Hawaiian Telcom" has provided me with a Motorola 2210 modem/router. I have had trouble trying to create a static IP with this router so (sorry if this was a stupid move) I decided to buy a linksys router to try to port forward with that. When my ports were forwarded with the previous ISP I was using a linksys router then. The now aged linksys router was replaced due to it getting wet, but that's besides the point
View 11 Replies View RelatedFor numerous reasons, I want to bind my DHCP clients to static IP addresses, but can't figure out how to do it in DD-WRT.
I've googled, but every link I click times out (for this specific search- my uplink is otherwise fine).
I know I can do it with hardcoded IPs, I'm just curious how static DHCP is done (and yes I am aware that Static is a contradiction in terms of DHCP. I want a given MAC to always get the same IP) and would like to have some info on this.
(call this reserved DHCP if you prefer... )
So I have AT&T U-verse and am teaching myself networking and am wanting to mess around in creating my home network and set up static IPs for my devices. I know how to set them up, but I guess AT&T is saying that they have to allocate the static IPs....pretty much they are saying I have to pay them so they can say ok I can use the IP addresses from xxx-xxx-x-10 to and then depnding on how many I want to have depends on how much I pay. This makes no sense to me. Why should I have to pay my ISP for static IP address, from my understanding those are things
View 3 Replies View RelatedI am in the process of acquiring a static ip address from my isp time Warner. I only want to pay for a single static, but I have a number of machines I want to put on the internet, a web server and a e-mail-server. Using a cisco router, a Cisco Rv 120w. Can I assign the static ip address my isp gave me to the Rv 120w and then crate a vlan to assign addresses to various computers. Or is this something my ISP does. I get the impression from the tech guy at Time Warner that this is something they do.
View 11 Replies View RelatedI'm connected through a simple non-configurable switch to a 172.20.0.0. 255.255.0.0 network, with a gateway of 172.20.2.2.
When i use DHCP, i am able to connect to the web.
When i change my ip address to a static address (with an available ip address and correct subnet mask and default gateway) i am unable to connect to the web.
In my router I can set rule that all traffic incoming to router's extAddr:8888, is forwarded to my intAddr:8888. But I also need reverse rule that packets originating from intAddr:8888 are translated to extAddr:8888. Can I do that? What technique can I search on google to find more information, because it is not port forwarding. I would calll it reverse port forwarding or static port address translation, but I do not find anything useful in internet searching these keywords.

View 1 Replies View RelatedI have a router manufactured by AirTies,the model is Air 4450.This has the capability of being an Access Point in a current network, which is how I want to use it. (Introducing it into my current Sky Broadband network with a Sagem F@ST 2504N router).However, I cannot access the configuration page whatsoever.The manual states the default IP address of the router is 192.168.2.254, so I have set my laptop to a static IP of 192.168.2.100 and patched into LAN port #1 on the rear of the Airties 4450, powered on the unit and cannot access the router at all.I have held down the reset button several times to no avail.how I can configure this unit ?
View 2 Replies View RelatedI've got a server that is connected to the network through one physical ethernet adapter. From my ISP, I got 4 static, public IP adresses, one of which is in use on the Host-Server itself, the remaining three each on a virtualized server. All 4 Servers are running on the same machine.Everything is running smoothly, however, I need to do some Bandwidth Management and Port Mapping, this is why I bought a ZyWall USG20, thinking it would be perfectly capable of doing what I need. is it possible, with a ZyWall USG20, to have all my four IP adresses being forwarded to the one physical machine, and apply some bandwith shaping and port mapping to it?
View 9 Replies View RelatedI'm using cable (7.5Mbps) w/ unlimited bandwidth . I have 2 wired PC on the network and 4 PCs connected via wireless. My current router is a Netgear WND3400 but I had a Linksys WRT160n v3 previously.
My problem is that I've been getting very high ping in games (PC) and also on my PS3 like > 400ms over the past month but only after like 9:30pm or so. During the day it's always smooth. I called my ISP and they told me everything was fine from their end and the modem too.
1 PC on the network makes the other PCs lag even if that PC isn't downloading or using any bandwidth at all? I did some tests today, like: I open CMD and type: ping -t url... and I get like 6ms but when that particular PC is powered on, the ping increases to > 400ms.
I have a Time Warner Cable business class service with no static IP, with a wireless modem which is plugged to a CAT5 distribution panel. On the jacks (2 other rooms on the house) I have a Linksys E3000 and a Linksys Valet router for signal boost and gadgets usage (TV, cameras, etc).The main router (TWC) has it's own external IP which TWC assigns to me and internally distributes via DHCP the range 192.168.0.x. With that said:
- The E3000 has a 192.168.0.6 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The Valet has a 192.168.0.7 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The main router has the 192.168.0.1 as the gateway and web-interface
Whenever I connect something to the E3000, it is distributing the 192.168.1.x range and the valet 192.168.2.x range.That works perfectly for my home based business until I decided to use more stuff on the network such as a IP printer, IP cameras, etc.
- The IP cameras are connected to the E3000 due to signal strength and I have manually assigned them the 192.168.1.15 and 192.168.1.16 IPs and ports 9001 and 9002.
- The printer is connected to the E3000 and I have manually assigned the IP 192.168.1.30.
Issue 1: Port forwarding On the main router (TWC - UBEE) I have tried to setup a port forwarding by informing the Local IP as 192.168.0.6 (E3000 IP), Internal Port 0, Public Interface IP (0.0.0.0), Ext Start Port 9001, Ext End Port 9001, Protocol - Both, Enabled Yes. On the E3000 I did the same config (screen shot attached e3000.png).This is not working properly. I can't get into the camera.
Issue 2: Printer/ The printer is only accessible if I connect to the E3000 (because it is on the 192.168.1.x network)
Issue 3: How to configure all the devices on the same subnet? If I want everyone to be on the 192.168.0.x network, how to configure properly the E3000 and the Valet? I have tried to force them into the same network but it would not work properly. It would not get an IP from the UBEE router (main).
After recently setting up a new computer, my entire network seems to randomly loose internet connection. The interval between connection losses is as short as half an hour but it sometimes goes several hours without dying; the connections is lost for anywhere between 30 seconds and 20 minutes each time it dies.The new computer is running Windows 7 and is using a Roeswill USB wireless adapter, but I have tired it with a wire and the connection still dies. I am disinclined to believe that this is caused by a virus simply because this is a brand new computer that has had only minimal use; to be on the safe side, though, I did do virus scans with multiple programs, however, I did not find anything.When the connection is lost, a yellow exclamation appears on the task bar's internet access icon. If I check my available networks, my network still shows full strength. I have tried disconnecting and reconnecting but nothing happens; I don't get any "failure to connect" type errors nor do I get connection back. I have also tried physically removing the adapter/wire and plugging it back in, but that doesn't do anything either.
I am under the impression that the new Windows 7 computer is doing something to temporarily kill the entire network, but I don't know what.For the record, my modem is an old Motorola and my router is an old Netgear. Both are quite a few years old, but I don't think they are the problem as my internet was fine before I added the new Windows 7 computer. There are wired computers and wireless computers running XP, Vista, and 7 also on the network.
I have 2 computers on a network, and 3 devices that use wifi on the same network. Basically when ever computer A is connected, every single computer or device on the network runs extremely slow, if at all. I get anywhere between 1200-2000 ping on pingtest with 2-60% packet loss. Even the speed on the "infected" computer A downloads extremely slow. I'm at a loss for this problem, everything runs slow and its because of the one computer connected to it. I have virus software on this computer, but its not the best so i'm not ruling out malware or viruses right off the bat.
Devices: Blackberry, Iphone, macbook (all wifi)
Computer A
Runs windows xp 32 bit,
amd processor
onboard video
[code].....
The internet modem runs to a router (Dlink dir615) then to a switch (or hub, if you will) and then to the 2 computers. The entire problem is solved by unplugging computer A from the system. But other than that I have no alternative.
I am in charge of taking care our small office network (about 25 PC's) and encountered a problem the other day. I got a call that nothing network related was working. I went to look at the switches/router and everything appeared fine. After some troubleshooting i found if i unplugged the switch and connected directly the the router everything worked prefect. Reconnected the switch, network goes down again. I assumed it was the switch at first but then did a walk around and a laptop was in a weird frozen state. I unhooked the network cable and everything started working away like it should.
View 9 Replies View RelatedRecently me and my girlfriend have been having issues with in game latency, receiving pings close to jittering to well over 300 where they were formerly in the 30-40s to identical servers. We live with a Chinese housemate who is extremely conscious of her privacy/personal space, we noticed a dirge of active ports on the router (both TCP and UDP) which seemed to have no association with any major application and assumed it was the old P2P boogie-monster. She is the only one who uses Wifi, an upon briefly deactivating the Wifi, all ping issues were instantly resolved. The bizarre thing is we still have plently of up/download bandwidth, I mean we're not swimming in a fibre optic connection but still a relatively healthy 1MB dl/70KB/s ul, more than enough for gaming.Deciding we needed a better idea of what was going on in the network, we downloaded Wireshark. We discovered a couple of things that might mean something, they might mean nothing at all:Firstly there was a deluge of random ARP requests coming from the suspect IP, something along the lines of:"who has 192.168.0.(random number) Tell (suspect computer's IP)"repeated over and over in bursts. A little googling found us this: Has Your Network been Now given that she is Chinese and is probably exposed to a lot of Chinese websites, is there any chance that this could be the root cause - could it drown the network to the extent that it produces terrible pings?Secondly there have been an inordinate amount of name queries coming from her IP to 192.168.0.255 (broadcast channel), they generally take the form of:
NBNS92Name query NB WPAD<00>
or
NBNS92Name query NB ISATAP<00>
and occasionally, it will name query my network id, leading to: (her ip being 192.168.0.3)
2144211275.734470000192.168.0.3 192.168.0.255NBNS92Name query NB (my id)<20>
2144231275.739314000192.168.0.3 (my id)TCP6658451 > netbios-ssn [SYN] Seq=0 Win=8192 Len=0 MSS=1460 WS=4 SACK_PERM=1
2144251275.741325000192.168.0.3 (my id)NBSS126Session request, to (my network id)<20> from (her network id)<00>
2144271275.744124000192.168.0.3 (my id)SMB213Negotiate Protocol Request
[code]....
Now combine this with the sometimes 9-10 active ports our router assigns to her IP (which don't appear to relate to anything according to numerous port id sites), does this send out a red flag to any of you? I realize it would be so much easier if I could get access to her computer, but as I said, she is very private and timid and doesn't seem to like even having people in her room, let alone letting them use her computer.
I updated my Mac to OSX 10.8 and now every time I try to login to my work network (a windows network) it locks my account. Each time, my sysadmin unlocks my account and I am able to successfully login one time but then, if I login again (after restart or sleep) I am locked out.

Wifi Routers: Dlink DIR-601, Linksys wrt54g, wrt54gv2

Copiersfax: 5x
Wireless clients: (iphones, laptops) at least 30
All has been working together in harmony for many years.Fast forward to last week when my hell began with intermittent crashes.Not sure what's causing the problem.When it happens, everybody loses their internet, the ability to communicate over the network; ping tests won't respond to anything (including the router) that exists on the lan, even with a static IP against other statics.In visually inspection of the switches and router, they seem to be happily blinking away with no apparent issue (visually).The only way I've been able to fix the problem is by power cycling the router.About 1 second after doing that, we're back in action for 2-6 hours (very unpredictable).I never had to power cycle any other devices)
Steps I've taken in troubleshootingeliminating potential culprits:
Replaced the router with a spare (new) FVS318G
Replaced the power supply for the router (suspected because problem remained after router swap)
Replaced cable going from router to lan switch
Removed linksys wifi router from network (the router had needed power cycling weekly and was old. So I unplugged it)
Removed Dlink wifi router from network (I hate dlink routers, so removed it).I'm at a loss.

View 6 Replies View RelatedMy Set up at home is as follows: [code] Now according to what I have read I should be able to set the subnet on .2.0 network to a subnet of 254 and this gives me 512 Hosts I believe however my question at this point is how to route between 192.168.1.0 and 192.168.2.0.Or when I set the subnet .254 does the router just route it automatically.I would still set the subnet mask on both networks to 254 correct? I believe I can only use 192.168.0.1 to 192.168.1.255 w/.254 subnet mask. However I already have some servers that are configured with applications (On the 192.168.2.0 network) that I do not want to change ips on because it would be a pain to reconfigure so, my other question is other than using .252 to extend it to 192.168.0.1 to 192.168.3.255, (I need the 192.168.2.0) is there anything I can do? Like use 192.168.1.0 with subnet mask of 255.255.254.0 to get the 192.168.2.0 network? The reason I asked is I was using a subnet calculator to try and figure this out but every time I put in 192.168.1.0 with .254 subnet mask it changed the ip to 192.168.0.1 to 192. 168. 1. 255.I would really like to use the netgear only. The way I have it now is not working I am able to ping the internet from the 192.168.1.0 network but I can't ping from 192.168.2.0 network to the 192.168.1.0 network.

I have a relatively simple question. I would like to create a private network within a larger network, the private network having several clients. I would ideally like the router to appear as the only device on the larger network and all data to be sorted by the router to the clients in the private network.
Will the Netgear FVS318G be able to do that? It seems to have the necessary NAT options.
