Cisco Routers :: Suddenly Loosing WAN Connection SG 100D-08

Sep 5, 2012

I upgrade firmware from 1.0.3.5 to 1.0.4.17 and from this time I can't connect to any site time from to time. I have simple DHCP WAN connection between my provider and the router, my computer connects to router by wire (only Cisco SG 100D-08 stands between them). When I can't access sites I can access my router and the router needs much more time to answer to me via http. I don't use any vlans or internet access to my computer or router.

Routers / Switches :: Loosing Connection From A DHCP Router?

Jan 16, 2012

We are in a hotel that allows us to use their router with a Hawking 300N expander. We seem to lose connection each time their router gets a new IP address. The router seems to lose connection frequently. Is there a setting in the expander that will allow the expander to "follow" the DHCP address of the router without having to take it down and go thru the setup each time.

Cisco Routers :: Small Business Pro Srp527w Loosing Connection

Oct 29, 2012

The router keeps loosing connection to the internet. I can still log into the router locally but cant connect out or in from the internet. Which is a big problem as i use this device remotely. I have tried different firmware (.9, .19, .27) the .19 seems to be the most stable but i am still having problems. The only way to rectify it is to reboot the router. Is there a fix for this or a way to schedule a reboot on the router.

Cisco Routers :: WRVS4400N Wireless Connection Drop Suddenly?

Apr 16, 2012

I see a lots of problem associated with wirless connectivity with WRVS4400N, with following config
 
Firmware version - Firmware Version: V1.1.13
Wireless connectivity - G/N Mixed
Auth - WPA2 AES
Everything else default and AUTO,
 
Problem:The end devices suddenly drop connection. Wired connection works just fine. The DROPPED device can not be reconnected. On MAC I get AUTH time out. I see the SSID being broadcasted from my HTC wireless analyster so radio may not be the problem. I changed to set the speed to G only or N only but not avail. ONLY way to recover from this is rebooting the router.

XBox Keeps Loosing Connection

Mar 29, 2013

My nephew's XBox (he's an on line gamer, and quite a serious one for that matter...) seems to boot him off line when someone uses the phone or goes on line on another computer. The house is quite far from the exchange so the average down speed is only 1.75-2 Mbps. This connection is through a BT Infinity R/S/F and I wanted to know if we could just add another R/S/F device and subnet the games console into it's own DMZ with full bandwidth access and then the normal broadband & phone on a different subnet also with full bandwidth access?

Cisco Wireless :: WAP321 - Loosing Connection To DHCP Server

Jan 1, 2013

I have two WAP321s in my office.  The network they are on is a single VLAN (172.16.10.x).  Both WAPs are setup with the same SSID, and I have setup Single Point Setup.
 
I am having a problem that was happening before I setup Single Point Setup, and it is still happening.  Basically wireless will be up and running fine for part of the day.  Then people throughout the office will begin to lose their connections to the DHCP server.  They still retain the connection to the WAP, but can no longer access the network. 
 
The only way I have been able to fix this issue is to reboot the WAP.  As soon as it reboots the connections come back.  At first I thought it was due to the number of connections (which is why we now have 2 WAPs), however we only have about 20-25 conncurrent connections. 
 
I put in the second WAP to try to balance out the load but this does not seem to be working.  Is there a setting I need to change on the WAPs to balance out the load?

Linksys Wireless Router :: WRT120N Keeps Loosing Connection

Sep 3, 2011

I have several computers and printers connected to a WRT120N router which is connected to 10mpbs DSL.  The computers are all running WIN7 and are hardwired to the router.  On the one PC, it keeps losing network connection.  I've tried upgrading the router's firmware, reset, etc. to no avail.
 
I think it may be related to the same IP address being assigned to multiple machines connected to the router.  Is there a way to set specific IP addresses to each item connected to the router to see?

Linksys Cable / DSL :: WAG200G - Keep Loosing Internet Connection?

Mar 1, 2012

My IP provider has upgraded my broadband speed in early Jan. They require ADSL2. It seems to coincide with this date that I keep loosing my internet connection on a regular basis, say every 2 days or so, but not consistent. The cure is to unplug the linksys WAG200G ADSL home gateway. Plug it in again and all is well, until the next time. On the box it says the until is ADSL2/2+ compliant.

D-Link DCS Network Camera :: 920 Loosing Connection To Router

Oct 13, 2010

I have just purchased a DCS 2121 (I assume that it is a similar model to the DCS 920 in US).I have this setup:

- Connected the DCS 2121 wireless to my Belkin Router with a fixed IP address. Firmware version 1.4 is installed on the camera.

- I have a Synology 209 NAS server with surveillance station that I have connected to the Camera.

I all works fine for 5 minutes to a couple of hours at which point the DCS 2121 loose connection to the Router and does not try to reconnect. If I turn the Cam on and off it will reconnect - and then loose connection again af a short time.This is totally frustrating since the purpose of the Cam is to work as a surveillance cam - it kinda loose its value by not being connected...

Acer Aspire 5250 Keeps Loosing Wifi Internet Connection?

Nov 27, 2011

I purchased a brand new Acer Aspire 5250-BZ669 that included Windows 7 just two days ago. Everything is working fine on it except for it randomly looses connection to the internet. I have an established network that I have been using for years. The signal strength is always 5 bars and excellent. I also have a compaq connected to the same network, and it never looses connection. However my Acer will randomly drop connection. I have no idea why. Sometimes it will connect again in minutes or sometimes hours. I am using a Linksys G Wireless Router(Model # WRT54G2), Atheros AR5B125 Wireless Network Driver, and a Atheros AR8152 Controller. I have enabled and disabled in addition to uninstalling and installing the driver and controller many times. I have also moved the router and adapter all over the house. I have downloaded the newest versions of every driver from the Acer website. I have googled for hours looking for the answer to no avail. I run the troubleshoot and the answer it gives me is to make sure all the connections to the router is secure, which it is or else my other laptop wouldn't work.

Linksys Access Point :: WAP610N Loosing Wireless Connection

Jun 13, 2011

I  had the WAP610N for a few months with no issues.  As always, I have a custom SSID and password, using WPA2.  All of a sudden, none of my mobile units (at least 5) are unable to connect via the WAP610N.  However, I can connect to a Netgear N750 w/o any issues.  When I reboot the WAP610N, it resolves the issue for a few minutes, but then behaves the same as before.  I know its not my network because, I am able to connect via wired and wireless via the Netgear.  I verified via the web interface that none of the settings/configurations have changed - but still nothing. Latest firmware has been applied.  Note sure If I should perform a factory reset or re-apply the firmware.

Suddenly SOL On Network Connection

Jan 23, 2013

I have a print shop that runs several computers on one network off of a single adapter. Last week the boss and I went out of town for some off site training leaving a single employee in charge of holding down the fort. When we came back we ran into a whole slew of problems not the least of which being that one of our graphics computers doesn't seem to want to recognize the work network anymore. It seems like the employee who we left (who, of course, "didn't touch anything") must have disconnected the computer from the network and started a new one as it is connected to one simply entitled "network". The issue I'm running into now is that when I check the network list the work network is not showing up at all. I've checked and I can ping the other computers on that network, they are all connected to the same network adapter, I just can't seem to get this one computer onto the preexisting work network.
