Switches :: Losing IP Address When Trying To Reset A Router
Jan 25, 2012
I own a HP laptop (runs Windows 7), and lately when I either turn it on or log back in for the first time in a day, it's not connected to the internet, despite my brother's desktop computer (Windows XP) being connected (it's right beside the router and modem). Before, we would have to just unplug the router for a few seconds and then plug it back in again to get the connection to work again on my laptop, which that alone we don't understand why, as there are periods of time we have no problems connecting on either end, like I just bought this laptop at Christmas and have had no connectivity problems until now. Now however, when we unplug the router and plug it back in, it kicks my brother's computer off the internet despite his connection being good prior to, apparently it loses its IP address when we do that. So then we have to unplug/replug the modem and router plus sometimes restarting my brother's computer to finally get it working again.

I recently switched routers to the DIR-615 and I'm trying to troubleshoot why one of our laptops keeps losing the IP address and gets a self-assigned IP address. I see the following messages in the log, I am wondering if the reason codes are listed and explained somewhere? I tried searching the manual but could not find any information.

ive been having a problem with my router since ive been using it for its wireless capabilities. it is a linksys wrt120n router. our internet comes from our local cable provider and it is good internet (10Mb download speed). running to our old router that split the connection between my xbox and our desktop computer worked fine and even for a large amout of time after i switched to this wrt120n there were no internet problems. now all of a sudden the router drops connection multiple times a day which can become a hassle when i'm doing something importaant and lose connection. and just a little bit of extra information i cycle the systems every time it does it and theres no fix.

I have a conflict with my satellite Internet connection between the modem and router IP addresses. I also somehow entered a password for the router which I now cannot duplicate. received a request for additional information which I responded to in September. I attempted to follow-up in October again, but I have not received any reply since the first one on August 11, 2011.

I am unable to connect to the internet thru my router, Lynksys WRT54Gs. The network worked fine before I went on vacation. I accessed the internet by connecting the ethernet directly to the modem, and have been unsuccessful at my attempts to reset the router with 192.168.1.1

I have 3 Dcs-3420's on the same network same static ip setup and they never have issues. Im testing 1 942L, I've upgraded firmware to1.11, but periodically the camera loses its ip address which is weird because it is set static. My wireless is set to Mac address security. Now camera is outside in a shaded area, over night the camera worked all night, this morning it has reset three times. Additionally, each time it resets/losses ip address it also loses the manually set time.

It is set to dummy mode so it should just pass through to the WRTG54S router which handles the DHCP.2) I have 6 computers sucking the internet off of the router. One is wireless.3) I have been set up for about 6 months this way. 4) I use to drop the DSL connection about twice a day. I would unplug the WRTG54S and plug it back in and everything would reset and work. Then, recently it has gone to about 15 times a dayThen, we have to make a major electrical change in the building, which required us to go to generator power only for 5 days. For 5 days, we never dropped the DSL connection a single time. Power was restored. Generator sent back home. Problem is back. Dropping DSL connection again.5) Hooked up APC battery backup power smoothing device to 3 cpus, WRTG54S, and DSL modem.

I started my PC (aser) as usuao but did not connect to internet that i am using TP Link modem/router, I turned laptop on and get conected the wireless is working fine, serached about TP links solutions and applied all of them, before I was using "obtain IP automatically" then I used to insert the required IPs manually, applied and save and restarted several times... still cannot connect to the internet while I still connected to the same modem+router via laptop wireless connection,
Finally I decided to format and installed new OS XP, though some wrong error was with my OS, unfortunately even after installing new OS still not able to connect, I checked the IP and tried both options and still cant access, i never experienced such..

how to reset IP address for Win 7 and it takes you to a XP dialog box...my problem is when I try to connect wirelessly I get the old ''Limited Access'' and not connected in the status box. And the wireless connection utility shows my old IP address as autoconfigured to IPv4 169.xxx.xx whereas it should be 192.xxx.xxx.x the 169 number was for a connection I had security on but that company went out of business and now I have an Alfa usb hi-gain antenna that picks up my work place that I can share a connection to but it keeps going back to my old IP address and when I go to the star>control panel>internet connection> connections tab all I have is the LAN. At this point I am having to use a Virgin Mobile usb dongle to go on line and it is as about as good as dial-up slow as Christmas in August...and would like to connect to the linksys at work which I show 4-5 bars in signal strength...

I just bought a SG200-18 in order to use LAG between a backup server and multiple computers and servers. Servers are supposed to all use 2 links and computers only 1.
As soon as I activate LAG on port 2 and 3, no matter what is connected on the switch I lose access to the switch interface (luckuly, it's still working on port 17 for a strange reason) and all computers / servers connected are randomly losing the network access. Everyrhing start to be slow but most servers and computers don't lose access to the internet. Browsing a web site will suddenly take ages but... it will work eventualy.
I already used LAG on other switch without a single issue.. The only uplink I have is to the router and I know that I don't have any issue with network cables....
So what am I doing wrong ??? I didn't even try to configure the TEAMING on the servers, just creating LAG on the switch will kill everything Oo.. I'm starting to think that my SG200 is dead out of the box.

I wanted to reset my IP address, so I called my cable internet service provider and they walked me through the process. I unplugged the ethernet cable from my router and connected my computer directly to my modem. Then, I unplugged the coax cable from my modem, plugged in back in again, and within Windows did ipconfig/renew in the command prompt. This successfully changed my IP address.
Then, I ran my wires back into the router again (instead of plugging the computer directly into the modem). To my surprise, the old IP address was back again! So, I went into linksys 192.168.1.1 screen to release the IP address and started the process over again.
I got a new IP address once again, but now the Linksys router can't seem to figure out the new IP address so nothing works going through the router.

I remember long ago I was upto some trial and error with my router and I ended up in changing some ip that I didn't know about that time, now when I was trying to forward some of the ports. I addressed the computer to 192.168.1.1 (as this was my ip that time I remember and on the box its written too) but it didn't respond, then I remember that I have changed this ip to something else and now I can't remember this.

I have a problem with my SG200, maybe more than one.
I tried to update to 1.3.0.59 this morning. It succeeded and the switch was restarted. After the restart I could no longer log into the switch. I tried to reset the switch but it still will not let me log in. I also tried to log into the switch using the forllowing method but I still cannot log in. I unpluged everything, held the reset for at least 30 seconds, waited 3 minutes, plugged a computer in and set it up to see the switch. All worked there and the login page appeared. It still would not take my login dredentials nor wold it that the default credentials. I has access through the switch but connot configure anything.

I'm trying to set up a new Cisco SF500-24P switch for our new Polycom IP phones but I'm having some trouble configuring them. It seems a fairly basic setup - We have a Cisco 2800 series router which is configured in a router-on-a-stick scenario to give DHCP addresses to two vlans, '1' for data and '20' for voice...
ip dhcp pool DHCPROUTER
network 10.10.0.0 255.255.255.0
default-router 10.10.0.1
dns-server 10.20.124.200 10.20.124.201
[cod]....
The switch worked practically straight out of the box- when I connected a PC or a phone into it they both got addresses in the 10.10.0.0 range and both worked fine. In the web interface I then set the Voice VLAN ID as 20 and as soon as I did this the phones can no longer get addresses from DHCP (although PCs can). The switch and the phone display both show that the phone is in VLAN 20. All ports are members of VLAN1(native, untagged) and VLAN 20 (tagged) and the port connecting to the router is trunked, as are the others.Also, I can ping 172.16.0.1 from the switch so there is no routing problem, although I did try using the switch as a DHCP relay to 172.16.0.1 but still no luck.I'm not sure how relevant this is but one thing I noticed is that data going to the router untagged (and therefore in VLAN 1) gets through but if I tag it with VLAN 1 then it doesn't.

The IP address is unknown and we need to reset the switch. SInce we can't access the configuration menus. I was wondering if we could reset this device to factory defaults another way. I couldnt locate a reset switch.

I can't seem to reset my switch and realized the reset button is missing/broken off. Is there an alternate method to reset the switch to factory settings? If not, how do I figure out the IP of the web interface, it is not the default.

My company just bought a SF300-24P, got it configured without much issue. Today I try to get into it and I can't. Tried via HTTP and console and nothing happens. Decided to try to reset it using the button on the front. Using the documentation, I held down the button for over 10 seconds. Didn't reset to factory defaults, tried again and rebooted it, still nothing. What I am I doing wrong. Also nothing comes up on console window and I'm using the setting for Hyper Terminal that the documentation says I should use.
