PC Gets Auto-IP From Internet Not From DHCP On Router?
Apr 21, 2011
I am trying to sort out an IP problem on my mates PC. I have setup a Linksys wireless router on his home broadband and it works fine with my laptop and gives me a DHCP address. When I try to connect his home PC either with a wireless dongle or ethernet connect it gets a Public IP address through the router and not one of the DHCP addresses. Even if you give it a static IP address and setup the router to accept it when you turn the PC on it still gets this public IP address. It is associating with the wireless router but only gives a local connection. I have done the ipconfig and it just renews the public IP address to a different one

my RVS4000 is not renewing DHCP lease in Auto mode. Connection lost after 24 hours.
WAN Internet interface is physically connected to cable modem - Motorola SBV6120E. Setup as DHCP server. Cisco RVS4000 is obtaining DHCP public IP without any issue, the problem is that the connection drop every 24 hours and I need to release/renew DHCP each day to be able to communicate after 24 hours. After I loose connection I need to release DHCP, the WAN interface goes down and I need to renew DHCP then. I receive the same IP address and connection is againg UP and working.
tried to load new firmware and also setup the router with default configuration, but without any change. as there is no auto-reboot function, it is really annoying to log into managment interface each day. I also loose remote access after 24 hours, so I am not able to access the rotuer from outside. My local provider do not support static public IP on WAN, therefore I have to use DHCP.

I've gotten a dir-600 and have been trying to configure it so that it won't auto connect to the internet. Some people in my network prefers to manually connect to the internet from their pppoe dial-up on their PC. I've tried changing it to static or dynamic ip in the LAN config, but everyone connected to the router from LAN couldn't dial out as well. changing it to ap allowed everyone (including wireless) solved the problem. but doing so, i am not able to access the router. the default ip's don't work, nor could i find the ip of the router on the network.
so what i want to do is reset it to factory settings and just use it as a hub/switch w/ wireless. don't want to use it to connect to the net automatically.

I usually put some stuff up for downloading and go to sleep. Now I setup my computer to auto-shutdown at a particular time via cmd, but I want o know whether it is possible for me to put some time settings in my modem+router so that it switches off at a particular time or something like that.Then when I get up next morning, start using it again. I don't want to keep my router on after it's not needed. Also I don't wanna keep it vulnerable after it's not needed, even though I have set it up quite securely. ( WPA2 PSK, and MAC filtering)

I have a 7604 Edge router that connects to our Data centre via Fiber.
but i keep getting input errors on the interface Gi3/5. i also found out that i cannot change the duplex settings on the edge router to auto, i only have two options of full and half and changing it has not worked either.
I have tried to use a switch in between the fiber modem and the edge router to try to manipulate the duplex settings, but when i tried it the port simply shutdown and then i have to reverse the configuration.
The software version of the router is 12.2(33)SRE3, i really need to sort this out as connection to and from the Data centre is quite slow.

Some of which use snap and some use mux, the router is the one will start the connection and will always be on, untill there is a power cut, if there is. At this point when the power comes back on and a packet's destination is the outside the router should initiate a connection over the atm.
•Do not use this feature on a router that initiates PPPoA sessions.
•This feature supports ATM PVCs. Switched virtual circuits (SVCs) are not supported.
•PPPoA does not support static IP assignments within virtual templates.
The second and thrid I can understand and the 3rd will just get assigned an IP address from the ISP.But with the first point how is it possible to set this up when the router cannot initate the connection?

Here is where I want to go:
Windows server 2008 (providing DHCP and DNS) 192.168.89.1 on all
Cisco SG 300-20 (switch) 192.168.89.3
all Clients(15 x DHCP assigned IPs) connected to switch
WRT300N(192.168.89.2) connected to switch
Internet modem connected to WRT300N
To achieve this I need to disable DHCP on the WRT300N, since my server is providing DHCP.The issue I have is that when I disable DHCP at the WRT300N, I lose internet connection (connected to either switch or direclty to WRT300N).

Region : Malaysia
Model : TL-MR3220
Hardware Version : Not Clear
Firmware Version : 3.13.12 Build 120703 Rel.58323n
ISP :
I'm using the TL-MR3220 hardware version 2.0. Firmware version 3.13.12 Build 120703 Rel.58323n. I'm using D-Link DWM-156 3.75G HSUPA USB Adapter.The problem I'm encountering is the router does not auto detect the 3G USB adapter when I power up the router. The router will detect the 3G adapter only when I plug out and plug in the 3G USB adapter. I used to have the same router but version 1.2. Version 1.2 does not have this problem.

I'm just wondering if there is any documentation that confirms if the 2 built-in Gigabit ports on a Cisco 2851 router support (or otherwise) auto-mdix.I can find information for the modules but not the 2 built-in ports.

Have a client wanting to hand out public ip addresses to all clients from a PFSense Firewall terminating the internet connection.
How do I allow the Cisco Switches currently in place, configured with private ip addresses in the 10.10.x.x ranges and Vlans, where the main 3550 layer 3 has defined dhcp scopes for each vlan, to relay dhcp requests from all vlans to the PFSense firewall?
I assume I would take off the currently defined dhcp scopes for the vlans and configure each vlan/switch with the ip helper address and specify the PFSense firewall and that Nat would have to be disabled onthe firewall?

I'm a bit confused about what a wireless range extender gives me. I have bought a Sitecom Wireless Range Extender 300N. This extends the wireless range of your router to parts of the house that have a weak signal or none atall.
It is setup correctly and is working fine, however, the SSID is different from the Router.
Essentially, I want to extend the range of my router to parts of the house that have a low signal. This range extender seems to be the correct product to do this. However, I want my clients to switch to the appropriate wireless access point (either the range extender or my router) depending on the strongest signal, how can this be configured?
When a client is the overlap area (the area where both the router and the range extender can be sensed) I want the client to switch to the strongest signal.
In my case My Router is in the loft and the range extender downstairs. You can still get a low signal from the router when you are downstairs but the range extender give a full signal. However, I dont understand what makes a laptop 'switch' from router to extender when its downstairs.
Because the extender has a different SSID a laptop that can still get a low signal from the router when downstairs doesn't automatically attach to the extender to get a strongest signal.
If I set the extender to have the same SSID as the router

Any direct download of the EA2700 firmware upgrade. My inet is not dsl or cable and will not let the wan port connect, therefor the "auto firmware update" will not work. I'd like to update it and see if it fixes it before I return this for a dlink. url...Anyways, I just want the firmware link so I can decide if this thing is going back to the store or not.

Purchased an EA4500 router. I'm using an old HP 4L laserjet and have it connected to the router via the USB port. I have 2 Mac's and installed vusb on both. I can successfully print from both Mac's, however I have to manually disconnect and connect the printer in the vusb client. I can't get the auto-connect and auto-disconnect settings to work by themselves. Any guidance on the proper settings here?Additionally, do I need to configure the printer driver though the vusb client? When I click "configure", I get an error saying"Cannot connect to Prolific Technology Inc. IEEE-1284 Controller.

we are busy with a local service provider ( ISP ) and they want to evaluate the SRP500 series and have a few questions that i cant answer clearly.
Can the router auto provision back to the ISP's site , aside from the USB bootup option. i.e manufacture programmed "version "to dial into a specific ISP to provision.
Central administration of SRP500 series: Can the ISP manage and update/ close down SRP500 from a central point. I know the TR069 is std on the SRP500 series, but what does this encompass.

I have an E3000 Dual Band. On my 5Ghz channel, I can select Auto(DFS) or I can manually select a channel.First of all, what does the DFS stand for? My 2.4 GhZ channel only has Auto, not Auto(DFS).
Second, when I select Auto(DFS), my wireless speed defaults to 144Mbps, and is only a single channel (I can see it in the in SSIDer utility). When I manually select a channel, no matter what channel it is, I get 300mbps and I can see that the signal is two channels (for instance, 36+40). Why Auto(DFS) doesn't automatically select the best channel and fastest speed?

I flashed the firmware and the ipv6 automatic is on disabled and I cannot set it to enabled.the 6rd tunnel option I can change but that has not effect- in fact from what I looked up it seems to be something used by some cable providers.hate to have to reset the router to factory defaults and then reset the network up - just to see if i can get the option to set IPV6 auto to enabled.

Internet Connection Sharing. On one of my pc's with Win 7 I try to use ICS and it does not work. I have tried forcing the ip address on the LAN connection on the host computer (192.168.0.1 or something) and it will not assign an IP address to any device hooked up to it.On my macbook running Win 7 and all the settings the same, all of the same devices work fine. I tried using a cross-over cable and switch (not at the same time) with no luck. Not using any firewall and I've tried for days.

I have a Linksys e3200 which was working great until about a week ago. Now any device that connects via DHCP does not have access to the internet, though devices set up with a static IP outside the DHCP range still have full access.The devices connecting via DHCP still have full network access, just not internet access.I tried most of the obvious fixes (reboot, changing the range and lease time for the DHCP) but have at best received a temporary fix.

I need another set of eyes on my config. I am trying to set up my router for a basic connection for the time being. I set my gig 0/0 port to dhcp I see traffic being sent and recieved but I can not ping 8.8.8.8. I am connected to a basic comcast modem from 0/0 I have also tried setting gig 0/0 to 100 full. I do have IP routing enabled. I believe I have my acl's configured correctly. I am wondering at this point if I need a static block of IP's from comcast.

I have some DHCP trouble since I subnetted my network with a 2921. My clinets are in 172.16.2.0/23 and DHCP servers are in 172.16.5.0/24.Sometimes, randomly I guess, I get NACK from my DHCP server, and if I look into DHCP logs I got something like this:
15,11/09/12,09:52:27,NACK,172.16.3.172,switchE51D12.host.com,A0CF5BE51D12,,0,6,,,,,,,,

To extend my wired ethernet I have purchased a WAP300N access point and connected it according to the instructions. I can see the AP from a wireless client and connect, but no IP number is provided to the client. The AP is connected to a router which has a DHCP server via wired connection (though a switch). The AP does it self get an IP number from the router but does not pass through DHCP requests from the clients.Occasionally an IP number is provided, but then there is no route to the LAN or the WAN on the other side of the AP.I have tried a whole lot of things to make it work (and been in the internet chat for two hours with a Linksys supporter, who could not make it work either).I have tried to set the IP number in the AP to static.I have tried to remove security (has to be WPA2 eventually, but for the sake of testing it has been removed)I have tried to factory resetI have tried to reinstall the firmware (the same version as the factory installed)etc.
