Routers / Switches :: Wired Router Is Upstream Of A Wireless Is It More Secure
Dec 22, 2011
2 routers in series, is one more secure. I recently asked about setting up two routers in series as routers, one wireless one not. It was my understanding that the computers on the second router would not be visible to computers on the first router, the wireless one. My assumption was that this would make it more difficult for someone who got access to the wireless router to also access those computers on the second router.
Yesterday, I changed my old belkin n1 router with Linksys WRT54GL router. Ever since them my upstream speed is really slow. I did the speedtest its like .5mbit. My downstream speed is just fine. This issue is only on wired computers, upstream speed on wireless computers is just fine.I retested router & modem several times, my upstream speed is normal when I connect cable directly from modem to my computer.Current Firmware Version is 4.30.14 build 5.
I have an RV042 router and I'm looking to monitor the total upstream and downstream traffic from within the router. I know there is tons of software that I can put on a netowrk computer to monitor traffic, but is there any software that I can put on the router itself that will monitor the traffic from within the router?
How to secure router on my mac - neighbor tapping into my internet service. How do I secure my Linksys router so only my laptop, desktop and iPad can use it? I tried going to 192.168.1.1 but got nothing?
Can I have a wireless access point connected, by wire, to say 2 PCs and a wireless router connected to the internet (+ other PCs) and the link between the access point and router is wireless (i.e. not wired)
My itty bitty manual just shows on how to hook up my router via cable modem...nothing on how to secure it. I go into setup of the router and see where one can add info but am at a loss what to enter. I tried, merely by guessing, applied the info, and screwed up my networking. I couldn't even get into my router to revert back, cause i couldn't get on line...finally i reset manually my router and all is well again, except when i see a list of nearby network users, mine is the only one that says unsecured.
I have 3 PCs (win7-64) connected to a wired gigabit network to achieve fast transfer of large files. Separately, at a distance, I have a modem-router to access the Internet. Internet access for the 3 PCs is achieved with each PC connected wireless to the latter modem router. The 2 networks are running OK and PCs can connect each other on both networks. Question: How can I know and achieve that the gigabit network is used for file transfers and not the slower wireless network? How should configure both routers and PCs to achieve this? I don't need the wireless setup to be a network, just to provide wireless access for each PC and that's it. I used to have the gigabit LAN configured with a Dlink DAP1522 bridge that created a single wireless connection between this wired LAn and the modem-router but it stopped working and I'm pretty done with it.
I'm trying to upgrade my existing Netgear wired router to a Netgear N600 wireless router. I was really hoping just to replug in everything and go. But because the wired router is setup for 192.168.1.1 when I plug in the wireless router it thinks nothing is plugged in because it too wants to use that IP address. How do I disable the wired settings
I have a Netgear WGR164v9 wireless router connected to internet directly by public IP and this router performing DHCP for wireless LAN ip subnet is 192.168.1.x. A server (DNS,DHCP & RRAS with NAT) connected with this router by ip 192.168.1.6 which has another subnet 192.168.10.x for LAN PCs. In this situation everything is fine like internet browsing. The only problem is wireless PCs (192.168.1.x) can't connect with wired LAN PCs (192.168.10.x). The router ip is 192.168.1.1. How can I configure to connect those two subnet's PCs?
On a second switch (ver 220.127.116.11) when I unplugged the power cord, to my amazement the switch turned right back on (about 1 second later), with the power cord removed. To verify that the power is indeed coming from POE, the upstream switch (ver 18.104.22.168) that is the same model (sg-300-28p), shows all 7 Ethernet ports connecting the two drawing from 2700mW, to 3000mW.
While the second switch is powered from the first over POE, the POE does not work on the second switch to power anything, and the system summary mentions something about "PoE Power Information on Master Unit".
Is this a stacking operation, and is POE on the second switch NOT supposed to work when powered over Ethernet from an upstream switch?
I have inherited a custome with a bunch of SG300's in their LAN room and one out in the warehouse.I need to setup a VLAN and the genius before me did not label which LAN room switch the warehouse unit plugs into. Is there a tool/method I can use to find which switch, and port this warehouse switch is connected to?
Having a design where an IBM bladecenter has two Nexus 4001i switches and each switch is connected to a Nexus 5k vPC pair, is it possible to configure active-active nic teaming on the hosts (blades) considering that the Nexus 4k switches are unaware of each other and blade has one connection to each 4k over either emulex or qlogic 10G CNA?
I have an issue with a Cisco 3750 switch stack which is connected to two seperate upstream Cisco 3750's which are administered by an ISP. The ISP is experiencing MAC address flapping from one of my VLAN SVI's i am using to route traffic upstream
As you can see I utilise a VLAN SVI to route traffic to the upstream 22.214.171.124 (illustration only) IP. As per the diagram of the topology attached, the ISP is receiving a MAC address flapping error confirming the SVI MAC address from my switch stack is being learnt on the trunk port connecting switch 1 and switch 2, and also the port (Gi1/0/48) directly connected to my switch stack. As these are all Layer 2 links essentially being passed upstream and then connected between the two ISP switches, we have a 3 way triangular loop formed.
If I was to remove the port channel configuration from the two ports associated with the VLAN SVI, am i right in suggesting this would still form a layer 2 loop? The two ports would still be a member of the SVI VLAN, and it is the VLAN MAC address which is being learnt by the two ISP switches on different interfaces.
Since I've bought my RV042 CISCO (v3 hardware, firmware v4.1.1.01-sp Dec 6 2011 20:03:18) i wasn't able to let it work properly with my two DSL network lines. I explain. I got 2 DSL network:
1- PPPoE with authentication (MTU setted as auto) with upstream speed 4Mbit/S and downstream speed 5Mbit/s 2- Direct line with static IP with upstream speed 7Mbit/S and downstream speed 1Mbit/s
I was never able to SUM the two WAN using the LOAD BALANCE set. I tried all combinations:
DSL 1 in WAN 1 or in WAN 2 DSL 2 in WAN 2 or in WAN 1
I've tested all type of speeds in WAN SPEED in Web Management
it seems that for some kind of reason it takes the upstream speed i can set in web management as the default value on which it decides to use the other WAN. When i set low upstream bandwidth for DSL 2 it's able to sum the down streams of both WANs but not the up streams.
I wasn't ever able to sum the up streams? How does it work?
I have a D-Link DIR -655 wireless router connected to my Time Warner Cable modem upstairs. Downstairs I have a PS3, Wii, Logitech Revue and a HP laptop. I get low signal strength downstairs(many walls) and would like to run an Ethernet cable downstairs to my devices. What hardware do I need downstairs to hard wire those devices? Not sure if router or switch and what kind. Do I need to make any changes to my existing D-Link wireless router? I want to keep the wireless available for cell phones and the HP laptop.
I've got a PC(windows 7) connected to a wired router(not wifi), and I also have a laptop that shares the internet with the PC using wifi. A wired printer is connected to the PC. Is it possible for me to share files and print using laptop? (Wifi Connected to a Wired Internet connection)
Adding ports to my Fairpoint provided Westell 7500 Rev D DLS modem router which has only 4 RJ45 ports. Bought a Linksys SE2500 gigabit smart switch but it doesn't assign IP or pass on router assigned IPs. Can't get ASSISTANCE from Fairpoint [successor to Verizon] configuring router or any advice on other ways to get more wired devices on LAN.For speed in backups I'd like 3 devices to be able to communicate at giabit speed Want to have an NAS and 2 Win7 Ultimate computers on smart switch, 3 other wired devices [WinXP, AT&T Cell tower, & DirectTV whole house SWM interface] and wireless on the router. 1. Are Fairpoint specs for DSL published so I could get another DSL modem router instead of the Westell or is it better to configure Westell as a router only and use a new to be acquired router with or without the existing or a new gigabit switch. I have a DI-624 from the pre-DSL Hughesnet satellite days.2. Are there less smart switches which would work better and let router assign the IPs?3. If this is too complex for me, can you recommend a remote access consultant to walk me through this for a fee?4. I'm 82, have been in computing since 1960, mainly in on-line end user environment mbut don't know the bridging, PPP PPoE differences, and implementation or configuration details of current hard and software except as a user.
I have a home network with a wired BEFSR41 that, for a variety of reasons, MUST be manually IP configured (DHCP off). All computers and other devices connected to it are manually IP configured. I desire to add a device that cannot be manually configured, and needs DHCP. I therefore need to daisy-chain two routers with the second one DHCP on (and manual IP connection to the main network). The new device needs two-way internet access, but doesn't care if it sees any other current network devices. I've tried several configurations, none seem to work.
we finally got my Cisco refurbished E2500 configured and working downstream from a UVerse 3801HGV box. We had to change the default IP address of the 3801 because it conflicted with the E2500's default. The E2500 is set up to get its Internet IP address using DHCP from the 3801. This is working fine for normal web browsing, etc. However, anything that requires extended connections (downloads, streaming, etc) freezes after a couple of minutes, forcing me to refresh the action to get it started again. Extremely annoying to say the least.
I'm pretty sure that I've tracked it down to the E2500's configuration of the 3801's DHCP allocation. For some reason, the E2500 wants to set the DHCP Lease Time for the 3801's assigned IP address to 10 minutes regardless of the upstream settings from the 3801. The 3801's default is 24 Hours which I've changed to 168Hours (7 days), but the E2500 stays stuck at 10 Minutes. Specifically, I'm referring to the setting displayed on the E2500 under Status>Router>Internet Connection IPV4>DHCP Lease Time.
I want to setup an home network with a wireless router and use multiple switches for wired connections through out my home. I currently have an Airport extreme hooked up to a cable modem and a leviton gateway hooked up to the Airport. The 2 computers connected to the Leviton are on a windows 7 homegroup and share fine, but won't share or discover any wireless device connected to Airport. My main goal is to have a wireless/wired network with all computers sharing information with each other. I want 2-3 wired switches/gateways with a min of 2 devices connected to each, connected to my wireless router whiich is connected to cable modem.
I have been involved in the Networking of a museum with a set of "Show" computers which display video, and for this reason cannot have anti virus installed becuase of the performace hit, and also the risk of pop-ups on the videos. They do however need to be connected to the internet as some are interactive and allow people to send simple emails, and they all need to allow remote support when things go wrong.It seems the networking was not thought out very well initially, and there is a single wireless router which serves the staff and public on a secured wireless network, but also serves the "Show" machines via a wired connection from one of its ports, which then connects to a master switch which serves the show machines.Now the wired and wireless is on the same network, and everything shares the same IP subnet (192.168.1.xxx), and this is not a good situation in terms of the securuty of the show machines on the wired network. So I need to work out a way to totally separate the wireless network (which will be very prone to people opening viruses in their emails etc), from the wired network (which will be the show machines which wont be touched by anyone).
I want to achieve this in the simplest and easiest way, and have been reading about the possibility of setting up a second wired router behind the current wireless one, with a different subnet IP address, to which the "Show" machines could be connected. The WAN port on this second router would connect to a LAN port on the wireless router, and thus the show machines could get their internet, but separated from the dangerous wireless network.Does this sound like a sensible start? Will the fact that the wired router (and show machines) are on a completely different subnet to the wireless router (and wireless devices), mean that the wired network will be protected? Or do I need to do more? And is this likely to work?

Region : Malaysia Model : TD-W8968 Hardware Version : V1 Firmware Version : 0.6.0 0.4 v0005.0 Build 130217 Rel.62075n ISP : TM Streamyx I have internet speed : 8Mbps. The status of Internet in the modem config as foloows: UpstreamDownstream Current Rate (Kbps)636 10240 Max Rate (Kbps) 900 23412 SNR Margin (dB) 12.8 23.5 Line Attenuation (dB) 8.1 1.1 Errors (Pkts) 0 0
from the above informations the upstream is 636 Kbps but when I did the speed test it show me that the upload not more than 300 Kbps.
I used another modem D-link modem and the upload is more than 550 kbps when I used speed test.
Actually the upload is very slow by using TP-link modem and when I used another modem the upload is double speed.
Is it possible, through a QoS profile, to control how much bandwidth a user gets to use for upstream traffic? I can easily set limits for downstream traffic, via the per user bandwidth contracts, but it is not obvious to me on how to control upstream traffic.
I have a number of class-'c's as a hand-off from my data center fiber to my 2960, which then sprawls the racks with about many 2950 switches, mostly 20 machines per switch. To allow machines on one 2950 to push data to another 2950 without routing back to my ISP's router(which costs money for bandwidth) isn't is possible to trunk one port on each 2950 to another 2950 and adding a addititional vlan8 to them. Then data jumps from 2950 to 2950 without going back to the 2960 or mainly not going back to my ISP's router. Is this the correct way to accoplish this with extra vlan and trunking the 2950's to each other or am I looking at this all wrong?
1- Router that is working as Router (IP: 192.168.0.1 ) ( Ethernet ) routing from : IP Address:192.168.67.83 Subnet Mask:255.255.192.0 DNS Server:192.168.100.1 , 126.96.36.199and its providing internet via Wireless.
