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?
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.
I have a RVS4000 witch I use as router, and DHCP server. I have a WAP321 witch I have configured SSID with one VLAN. Both devices have fixed IP address. I can connect computer to the wifi access point. But the computer cannot get an IP address from the DHCP server of the RVS4000. If I set the IP configuration manually, it can get an access to the network and Internet.
With another wifi access point it works, the computer get an IP address for the DHCP.
What should I have to do to make my DHCP server works with my wifi access point ?
Setup a WAP321 with the new 220.127.116.11 firmware. Setup 2 SSIDS:
WIRELESS (vlan:1) GUEST (vlan:99)
The wap is plugged directly into a port on my router so I configured the port and additional vlan99 port. I have a DHCP scope assigned on the router to both the port and port.99 interfaces.clients on WIRELESS have no problem and work correctly, however when a client joins guest...a packet capture on the router port shows that a dhcp request is being received for the same MAC on both untagged and tagged 99 interfaces....thus it appears the WAP is not handling the vlans properly

Not sure if this is a problem with the switch or the wireless AP connected to the switch, but I have a couple of 3560's, one is a 3560G and the other is a 3560, both have phones and wireless ap's connected to them. The ap's on both of these switches continue to loose there ip address and thus disconnect from the controller. This happens about once a week, but the odd thing is that the phones never loose there ip address. All of my other 3560s and 3560g's that have AP's and phones connected are working fine.
Started this morning woke up checked my phone no wifi hmm weird checked my hp tpuchsmart connected but jo internet access checked my router(netgear wireless N 300) made sure my modem and all wires are connectedNext went to my router ip 192.168.1.1 after reading some forrums i thought maybe if i changed the ip or sum i would have worked i know dumb though.. any way i believe i disabled my dhcp.. and one of the ip ad on the same page to 192.168.1.3 thats when it got worst i tried ipconfig/release saysNo operation can be performed on bluetooth network connection 2 while it has media disconnected.No operation can be performed on local area connection while it has its media disconnected(Its a wireless connection from my touchsmart to my router) I have tried goin back to the routers page but i can no longer find itI have also tried ipconfig/renew but i get this...No operation can be performed on bluetooth network connection 2 while it has its media disconnectdAn error occured while renewing interface wireless network connection : unable to contact your dhcp server. Request has timed out.No opration can be performed on local area connection while it has its media disconnected
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?

That's a wonderful router on the paper! Really it has some problems with the wireless connection and the dhcp server. After 2 days of i must forced to reset the router because it refuse any wireless connection while the internet browsing on the other pc connected via ethernet ARJ45 is very slow.To complete the scenario the router doesn't allow any acces to his console page ..so what's the problem?
I try to change any channel for the wireless without no positive result.I bought it on amazon but if this situation will continue without any solution from tp-link i will forced to send it back with a totally negative feedback on the product.
I Updated the 5508 from 7.0.230 to 7.4.100 and made it a cluster.Sinse the Update the handscanners loose the connection to the AS400 Application.Where to start troubleshooting?I did a debug client, I see the client is roaming but I can not say if there is a relation between roaming and loosing connection to the application.
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.
We assign in our IPSec VPN the tunnel-address from our centralized dhcp server pools.In the profile we have two server's ip configured.In test (whireshark) we noticed that the discover always go to the first configured ip.
I do not understand and could not finf hints how the function is.
- backup server with a timeout when no answer comes from primary ?
- should ASA do simultaneous discover to all configured ip's ?
=>Problem is, that although the first server not answered in a timely manner, we noticed no discover to the second.
I just bought a WAP321 Wireless AP. I wonder why it cannot sync with our time server automatically. Every time I reboot it, the system time become "Fri Dec 31 1999 12:00:00 UCT". I have to do the sync manually by clicking on the "Save" button under the menu Administration > Time Setting.
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?
Is there a way to configure a DHCP server for my internal subnet of 192.168.20.1 which is on a 3550 layer 3 switch from my 5505 ASA Firewall.My subnet of 10.1.1.0/30 is connecting my 5505 to 3550. All I'm trying to do is run a DHCP server down to my hosts. The only options on ASA 5505 is
dhcpd address 192.168.20.1 - 192.168.20.254 outside or inside, which conflicts with my subnet of 10.1.1.0 used to connect my internal subnet of 192.168.20.1 for the whole network.
When I used my router it did not need the (inside, outside) keywords and just an ip helper-address command. How do I configure my my firewall DHCP server to propagate the 192.168.20.0 network through my 10.1.1.0 connection.
Ok, so if i open Utorrent and let it download for 10 minutes i loose my internet connection. I usually will disconnect my cat5 cable and plug it back in and it doesn't work so i would open up the CMD line and try to reset the network connection but it doesn't respond so the only way i can reset it is to restart the the computerI've tried reinstalling Utorrent but i still keep loosing my connection, yet all the while I am able to run netflix on my PS3 so my internet connection isn't going down.
I upgrade firmware from 18.104.22.168 to 22.214.171.124 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.
my linksys e3000 router loses connection quite often. E.G. we lost power last night and i tried resetting the router but it didnt work so I had to uninstall and then reinstall the router. A few other times it would lose connection for no apparent reason.
im loosing connection every few minutes , tried ipconfig /release , ipconfig /renew and im getting this error every time : An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has timed out. After typing ipconfig /all DHCP address is 255.255.255.255 and this IP 192.168.100.10. Tried other things like flushdns / netsh commands and nothing want to work. My connection works only after i restart my modem. Modem type Ubee 3236. The modem is new got it 4 days ago. And also why i cant access the modem configuration page by typing my default gateway in browser ?
I have recently changed my router from Netgear to TalkTalk because of an intermittent signal, no problem with my desktop ethernet or laptop wireless or tablet but I keep loosing connection with my WII internet connection for Netflix.
We installed a DIR-615 Vers. E1 FV. 5.00NA and since then i-Pods and i-Pads keep dropping wi-fi connections. All wireless PC's and printers are working fine. We have configured the wireless as:Mixed 802.11 n,g and b. Auto channel csan enabled, using channel 6. Wireless security is WPA-Personnal. WPA is configured as Auto, TKIP and AES with a pre-shared key.
My Cisco X3000 keeps loosing the internet connection after 1 day and will only reconnect if the device is rebooted. Pressing the Internet connect button in the Status page does nothing.Even when the Internet connection is lost, the wireless network is working 100% and all the devices on the network stays connected and are accessible.The router has been updated to the latest Firmware available from Cisco v1.0.03 build 001 Jun 11,2012
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.
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.
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...
Bought a Dir-600 from challenger, used it for 3 months and started expericing the common problems of loosing internet connection highlighted by many users here and in other forums. Would always have to do a modem / router power cycle to get it going again.Slightly after 3 months... the thing went dead. Can power up but no response. Cannot detect the modem.Got a one-for-one exchange at Funan. Used the 2nd one for less than 2 months. It just went dead on me! Same problem...
I've recently upgraded from a WAG54GS to the WAG320N. It seems to work OK for a period then looses the connetion to the Internet - DSL light on but not the Internet light. Normally I need to re-set the router to re-connect (either through the back switch or through the setup page)
This is my DSL information from [URL] whilst connected OK

When the modem looses connection to the Internet; the DSL Noise Margin drops way down to 0.0 or 0.5.
since a couple of days I've a strange behavior in my Spanning-Tree Topology.Every time I plug in a new Switch ( e.g. WS-2960S ) a topology change on my root bridge occurs and all client losing connection to the default gateway.The root bridge is also the default gateway.

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.
