How To Block Certain Wired Devices From Connecting To Router
Jan 15, 2011
I have a linksys wrt54g router. i need to block all devices except one from plugging in a wired device into the back of the router. i tried the mac filtering, but i didnt work. Is that for wireless only?I can also block local ips (192.168.1.x), and was going to go that route and only allow my local computer but i was afraid if i restarted my router or computer the ip would change and i would be locked out.
Noticed several devices have connected through my home network previously. Not sure how it is done,currently these inactive devices are displayed, i would like to know how can i block them from the firewall just in case it is connecting again?
how to block a user from using the internet when they plug their computer into a router. My roommate has refused to pay her share of the internet and, being a college student, I don't have enough money where I feel generous enough to let her have free internet after stiffing me. Basically, I have 2 routers at the moment (hoping to fix this soon): my Qwest modem works as a router but I also have a Linksys router connected to it. The only phone jack is in her room so I have no way of stopping her from plugging her computer straight into the modem and/or router. I've configured the wireless so that she would be unable to access the, wirelessly but I'd like to know how to prevent her accessing the internet when she plugs her computer directly into either component.
if the firewall rules in the RVL200 work for inter LAN routing as well as LAN<->WAN? I need 2 separate networks in a house, 1 for business 1 for family, and I want to only allow my IP on network 1 (family net,10.0.0.0/24) access to network 2 (business net 10.0.1.0/24). I want this as if I change rooms were a access point for business is not available I can use the home net and specific IP to access certain business net IPs. I saw you can turn inter vlan routing on or off, but it wasn't clear on firewall rules.know of a similar router in cost but with gige instead of 100Mb ports?
All of a sudden my laptop, android phone and blu ray player (all wireless devices) can't communicate with my wired devices (marantz receiver and samsung tv). Everything still connects to the internet independently but i can't for instance play music from my wireless laptop to my wired marantz receiver. I had no trouble with this last week and didn't change anything (that I'm aware of) I did get Verizon to switch out my router but it didn't solve anything. My wife's computer also cannot connect to wired devices. Lastly, if I connect my laptop with via ethernet cable it sees wired devices fine. I tried shutting off windows firewall but didn't work. I have no other firewall/virus software installed. I can ping to all devices (wired and wireless) from my laptop.
I currently have an old Linksys WRT54G router with 4 ethernet and 1 internet port. I have an old Sprint 660 modem connected to the router for internet access. I am also using 3 of the 4 ethernet ports for wired devices (main PC, NAS drive and Dish Network net access). I have another PC and a printer connected wirelessly to the router.Now, with my modem going bad, CenturyLink has provided a combo modem/router (EQ660DR-F1) to be used in place of my Linksys router/modem, providing wired, wireless and modem capabilities in one.My problem is that the new router/modem has only one ethernet port along with a DSL port. Obviously, I can connect my main PC to the ethernet port, DSL to the modem port and connect my 2nd PC and printer wirelessly as they are now. How I might connect my other 2 wired devices, possibly by a hub, AP or bridge or some other means? Can one of these be connected by wireless to connect the other 2 devices, or do these have to be connected physically by wire?
The problem that I'm having is basically that my router isn't giving right ip addresses to my devices. I've tried to connect a wireless printer (HP for doubts) and the router gave a 169.254.XXX.XXX ip address to it. If I unplug/plug the router, the problem is solved. It can also be fixed by using the "reboot device" tool that the router has at the configuration page. But this only works for some hours, so it isn't
Now, it isn't a printer problem. It has also happened with some notebooks, with around 5 to 6, not all of them. I've tried changing channels, resetting the router, changing password, security password type, changing firmware (present is 3.11NA H/W C2), and nothing can fix it.
I just now installed a new EA4500 Router. It installed itself automatically without a problem, by running the setup CD. No devices other than my hard wired computer and modem are connected yet.
When I went into Start > Cisco Connect to look around and check it's version, etc., I immediately got a "There's an important update for your router" notice. My concern is not wanting to install The Cloud at this time (although I wouldn't rule it out later). There has not been a trace of it so far.
I currently have Firmware Version: 22.214.171.124507 and Software Version: 1.4.12100.0. What this Important Update may be? Is it the "dreaded" Cloud? I'd rather avoid the whole rolling back to pre-Cloud issue for now, if possible.
Wireless router started randomly not allowing any wireless devices to connect to the network. A wired cable worked fine, but not wireless. So we had to unplug the router and then it would work fine.You could see the device, but not connect. We moved our wireless phone a little farther away from the router thinking it was interfering, but still no luck. It didn't matter if it was an iPod, our BluRay player, or a laptop.
The laptops and the desktop in my home connect perfectly fine to our wifi, but all other devices like our iPhones, iPads, Nintendo DS, Nintendo Wii, and a 2006 hp laptop will either show a connection, but the connection doesn't actually work, or there will be a broken connection shown to our wifi. All these devices (except the Nintendo devices[only because we haven't tried it out]) will connect and perform on wifi elsewhere.We have a d-link router?
I I use a Linksys E3000 router. Sometimes when I look at the network map I see a device called "Unknown." It appears as though the two notebooks sometime are going through this device to access the Linksys E3000. (I've checked when both notebooks are on and I can determine what devices are connecting directly to the router and what devices are going through this unknown device.) Is there any way to determine what this unknown device is?
I have 3 computers in total: 2 desktops and 1 laptop.
1. My primary PC is connected physically to my router.
2. My (downstairs) laptop is connected to the wireless.
3. My other PC connects to the wireless network via USB wireless adapter.
I was having issues getting #3 connected to the wireless network. I used the Wi-Fi Protected Setup™ PIN number provided to me by the Linksys Wireless Manager to no avail. The E3000 router and #3 could never find each other.After calling support, it turns out that more often than not, "other" wirless management software (in my case Linksys Wireless Manager that came with the USB device) was interfering with my Windows XP Wireless Manager.Rule of thumb: Always let your native operating system manage the wirless networks that are available to it. It does a far better job and is 10x more reliable than software provided by 3rd party vendors.Specific to my case: Windows XP, I had to enable the Windows Wireless Manager and uninstall the Linksys Wireless Manager Software. Here it is...Enabling Windows Wireless Manager These directions are for Windows XP:
1) From the Windows Start menu, click Control Panel.
2) Click Network and Internet Connections.
3) Click Network Connections.
4) Right-click the icon for your "wireless network connection", then click Properties.
5) At the top of the window, click the Wireless Networks tab.
If the "Wireless Networks" tab does not appear between the "General" and "Advanced" tabs, you are not on/in the wireless network connection settings:a) click cancelb) Right-click the icon for your wireless connection and choose "Enable". c) return to step 4 6) Check the checkbox next to "Use Windows to configure my wireless network settings".
These directions are for Windows Vista:
1) Go to the Windows start menu and then the control panel.
2) Open Network and Sharing Center.
3) Click Manage Network Connections (from the left side menu).
4) Right click on the network adapter 'Wireless Network Connection' and choose "Properties" and click "Continue".
5) At the top of the window, click the "Wireless Networks" tab.
If the "Wireless Networks" tab does not appear between the "General" and "Advanced" tabs: a) click cancel b) Right-click the icon for your wireless connection and choose "Enable". c) Return to step 4
6) Check the checkbox next to "Use Windows to configure my wireless network settings".
Just replaced a long-serving WRT54GS with an E2500 to gain a single feature… DHCP reservations for a bunch of web cams around my home. So far, the owner/user-experience with the 2500 has not been as positive as it was for the 54 or any of it's predecessors here and at my business. They just worked when you set them up, and once set up, they stayed set up. Zero futzing around with details. Some issues I'm seeking more expert input on:
My Panasonic Viera DVD/blueray player can access the web. Worked fine on the 54… access "Network" and 50% of the time it would join the network then and the other 50% of the time, you had to try a second time which I presume was the time it took for the device to gain access to the network. With the 2500, you can't ever (so far) get on by selecting "Network"… you have to go into the sub menu and have it dwell in the Network menu where it appears to make an ongoing effort to get onto the network. About 30% of the time, you get on… the other 70% no joy.My HP wireless printer will join the network if you dive into its menu system and tell it to look for the network. However, sitting at any of the computers on the network, you can't "get the printer's attention"… it just doesn't join and the print fails. You go over and use the printer's menu manually to get it on and it stays on for a short time, but it soon quits and that's the ball game.My Google Nexus One phone is a slightly different experience… it goes off the network as soon as you shut the screen down but, it seems like it comes back when you turn it on. With the 54, it seemingly remained in touch with the network better… things came in over the net while it was in my pocket. So, works better than the other two but I don't see why it goes away when on the 54 router, it didn't seem to.
In case it matters, this system is set up with DHCP, WPA2/personal and MAC filtering as was the case on the router(s) it is replacing. UPnP has been disabled. On 1.0.03 of the firmware. There are 6 DHCP reservations which also receive port forwards. I have adjusted the Beacon Interval, Frag threshold and RTS threshold for both frequencies and the MTU, all in accordance with recommendations under the support area for this site. Since everything worked well for both the 54 and its predecessor, I have to believe it's the 2500 that's the problem.
I've came across IP address that aren't enough for some users in the company. The IP addresses are more than enough to cater to the user's notebook or PC. However, some users does not know that there are actually limits to the IP we have, so quite a number of them actually uses their mobile / pads to tap the company's wireless.
I was wondering if i could restrict that particular user from tapping onto the network. I know it sounds a bit impossible because DHCP doesnt have that smart function to block whoever we sees deemed as a "nuisance".
I am trying to allow a block of 7 or 8 devices to access the internet all the time. Two other devices I would like to allow internet access during a set time range. Finally I would like to block internet access to all devices not in one of the above groups. I need to use MAC addressing to identify the allowed devices. I was able to do this with my old WRT-54G but the DIR-825 is giving me trouble.My main problem occurs when I try to block access to "Other Machines". When I do that all devices on my network are cut off the internet.
I was attempting to use my EA4200 in bridge mode but found out for some reason my devices weren't connecting to the internet. So I decided to try to access the router through the IP address of the router with no avail. So I pull the router and plug it in normally and notice that it keeps flashing. So that already gives me an idea something is wrong. I go through the process of unplugging everything from the router, and plugging my PC directly into the LAN port 1 of the router then powering it up. On my network connection list it keeps trying to identify the network but keeps failing (keep in mind that the router still is flashing). So I decide to attempt a 10 second reset, then a 30 second, then a 30-30-30. All with no success. The router keeps flashing.
Which gets me to the point where I am now... router flashing at me, and wondering if this now out of warrenty unit was a waste of money. I am noticing that a lot of people have had questions and issues with the E4200v2 which now concerns me, well hopefully this can be fixed.
Okay we have the router downstairs with a powerline ethernet on the firs and second floors so we can get the net.
Our house must be made of lead or something, because I very rarely get a decent wireless signal which stays consistant. Because of this I wanted to connect my laptop though the powerline but for some reason it doesn't work.
When I plug in the network cable it just hangs on identifying for a minute or so then comes up with "unidentified network" saying its connected, but has no access to the router, the internet etc etc.
Connecting the laptop directly works fine however. I've also attempted plugging the laptop in via a usb / ethernet connector, but that still hasn't given any results with the exact same issue. When i run ipconfig /all this is what comes up.

I recently borrowed a friend's desktop and I am having issues with connecting with the router through an ethernet cable. I go to troubleshoot the problem and I get "Local Area Connection 2 doesn't have a valid IP configuration". Its nothing with the router because when I plug my laptop in with the same ethernet cable, I am able to connect perfectly.
i need to connect a linksys e1000 to an existing dlink router. i have tried several solutions that i have found on the internet, but none have worked. i need DETAILED instruction tailored to e1000 specifically because i am having trouble with dhcp definitions as i have not done this in years. i can get it to work, but i have to maintain security and everything i have done still allows me through to dlink router.
Small office, 2 RV042, 2 DSL connections. 1 is used striclty for the business side, and the other is for our CCTV network. They also have seperate DSL connections as we have 2 external IP address for clients to connect remotely. We don't want to take away our exisring setup, but would like to bridge both networks so a few of our internal clients can connect to our CCTV network and use some of the devices. Right now they come in on VPN but its not as fast.Is this doable without adding additional hardware? Both networks need DHCP enable as well.
I've installed a RV042 and my terminals cant even ping each other. They have Internet, but they cannot ping each other, or open network shares. It is not a dns problem becouse it does not work with the IP.
Final results are that if I hard ware connect my computer to my PS3 I can acces Media Servers.When connected through the router though my computer acknowledges the PS3, it cannot connect to Media Servers.I have the Linksys BEFSR41 v4.3.
we have Cisco 6509 as a access switch in our network. Each user has an IP phone and a computer. we are going to implement 802.1X for end users by next month. I need to check all the users activity in the network like if someone plug an access point to the network or a router.I just checked Cisco NAC and how to detect those activities on the network.
I need to get more details on Cisco NAC or other products for that purpose. also what is the difference between Cisco NAC and application like Microsoft TMG?
is it agent less or I have to install something on computers? is it working as a default router for users computers?
I have a home network that uses a DLINK DIR-655 router. All of my devices ( a mix of wireless and wired) except one--a windows xp SP 3 desktop that stopped working yesterday. Some viruses, and adware were detected and it has not worked since then. What I have done.
I bought a Cisco Linksys RV042 (Firmware Version: 126.96.36.199-tm) a month ago. I installed it with two Cable Modems (Webstar DPC2100R2) from the same internet provider and with the same individual bandwidths for the two of those. My setup is Dual Wan mode since I only bought this device for load balancing the traffic through the two WAN connections. I need to clone both WAN MAC addresses on the router ports in order to get connected to my ISPs provisioning server. The RV042 has no issues getting a connection on WAN1 when MAC cloning has been made on this port, however, when I clone (user define, different from WAN1) MAC address for WAN2, this port never gets a connection and stays on IP 0.0.0.0 all the time.
I’ve tried factory reset, reloading the latest firmware (which already came pre-installed), switch modems from WAN1 to WAN2 and vice versa, disabling Firewall, turning on and off the ports on Port Management tab, changing SmartLink to Load Balance mode, enabling and disabling Network Service Detection, DHCP vs. Static IP on WAN ports, manual setup, setup through the wizard.
Nothing seems to make WAN2 port function correctly with the User Defined MAC address. The only way to make it work is using the factory (default) MAC address on WAN2, then it gets the IP address from the modem. Again, WAN1 works correctly with a user defined MAC address same as with Default MAC address enabled.I have read endless customer’s posts having the same issue from several years ago in this Community Forum and all over the web, and none of them have had a definite solution to the problem from the manufacturer.
My Linksys WRT120N router was working fine for all of 1 and 1/2 months and suddenly it stopped making the internet connection. At first nothing could access the internet but now that I've reset the router (via the little reset button in the back) my Kindle can access the wireless, but of course no password etc. I actually don't know how to put back the username and password for it. When router is connected: When I troubleshoot the connection by clicking on "Repair Connection" it takes about 2-5 mins "obtaining a new network address" then I get an error saying "The wired connection to your router was not automatically repaired. X Local network: Not connected.
if there is any method to block the internet connection for adobe acrobat x pro 10. Actually I do this, because currently I am using a trial version of adobe acrobat pro 10, and I am using an unpermitted serial number (crack). so each time the serial is detected immediately when I connect to the Internet.
I have a wireless G router and all of my devices that connect to it right now all have wireless adapters. I have several devices in a media closet (about 3 or 4 - Blu ray, DVR, ect) that only have wired ports. Since all these devices are right next to each other, I don't need to buy a wireless adapter for each one because that's just pointless. is there a way to have all 4 of these wired devices connect to a central device, which in turn this device connects to my wireless network? I know there is a way I just haven't been able to figure it out.And then, with this new device, is there some special way it has to be configured?
