Cisco Wireless :: WAP4410N - Duplicate IPs When Repeating Signal
Mar 17, 2010
First here is our network breakdown
8 Windows 2008 Servers - UN effected
5 Windows 2003 Servers - effected with dupe IP's
We have AP - A, B and C all configured static and outside of our DHCP scope
A - 104.240
B - 104.241
C - 104.242
WAP A is setup to allow the Mac's of A and B to repeat its signal. The issue starts about 1-2 minutes after I set B and C to client/repeater and select A in site survey then save the settings. Obviously its weird that only our 2003 servers are getting this error.
The system detected an address conflict for IP address 192.168.105.201 with the system having network hardware address *MAC ADDRESS OF ROUTER A*. Network operations on this system may be disrupted as a result.
Is it possible to use WAP610N Wireless-N Access Point repeating signal with another WAP610N Wireless-N Access Point?what the range of signal when using a single WAP610N Wireless-N Access Point ?How many devices can connect to WAP610N in the same time?
I bought TP-link wireless repeaters which i have failed trying to setup to an eircom zyxel dsl modem (ISP provided modem)i set it up as a universal repeater and had it auto latch on to the eircom modem but it just doesnt seem to boost the signal.i have turned all encryption and this doesnt work either. I have setup this situation using a netgear dsl modem and a netgear wireless router which if i remember i made a mac bridge, and it works great..am i wasting my time trying to get a TP-link talking to a cheap isp modem? i was reading an article somebody wrote that was doing the same thing yet the modem wasnt the same as mine, they said they got it working using WDS...and that the tp-link doesnt know about WDS and you need to use telnet to change settings on the tp-link looked a real hassle anyway.
I currently have a WAP4410N connected to an ethernet switch and the signal is very weak when attempting to connect to the AP from 4 rooms away. The structure is all block and the signal does not do well between the solid walls. I would like to roam from room to room on the same SSID. how to have the second WAP4410N repeat the original signal and reaplify it from the first WAP to solve this issue. Also, I cannot connect the second WAP to the ethernet switch it must be wireless.
we purchased 8 WAP4410N access points to cover our entire school with wireless internet. 2 of those could not have access to a wired network accesspoint, so we wanted those to repeat the signal of 2 others. The ones who are to provide the signal are set up as access points, with the option to allow the signal to be repeated enabled. The mac adress of the other access point is provided, and the channel is set to 6. The 'repeat' 4410N ones are set up as wireless WDS Repeater, with the mac adress of the remote access point entered through the site survey. The channel is also set to 6.
When I connect with the 'repeaters' however, I only get limited access, cannot get on the internet, and I cannot change the network settings in Windows 7 from 'public' to 'business'.
Purchase the unit from Amazon and installed it in December. Device worked perfectly with excellent coverage for approx 14 days then I got a call from the location stating that they where not seeing the SSID. Power cycled the unit and still nothing. The only way I could get a signal is if I held the wireless device within one foot of the WAP4410N and even then I would only get 1 bar of signal strength.
Im having problems with setting up my cisco WAP4410N as a repeater to extend the signal of cisco E2500.It works fine when there is no password to be set on both devices. But when either one of these devices had beenset a password on it, then WAP4410N failed to extend the signal of E2500.
I tried steps as below:
1. Same password type in WAP4410N and E2500.
2. Different password type in WAP4410N and E2500.
3. Set password in WAP4410N ONLY.
4. Set password in E2500 ONLY.
All steps above makes WAP4410N fail to extend the signal range of E2500. WAP4410N successfully works as a repeater to extend the signal of E2500 when there is no password to be set on both devices.
Any AP that would be able to wrielessly repeat traffic to my SA520W (so that the AP has no ehternet wiring at all). First off, there is no WDS option anywhere in the SA520W, so there is no method for which to simply create a WDS link between the two devices. Yet the Factory Default Settings table in the SA520W Admin guide indicates there should be (search on WDS in the PDF to find this). both at the lack of integration of these Small Business Pro devices, and moreso at the fact that I was told that these two would be compatible for wireless-only repeating. I've been messing around for hours trying to get something to happen. Maybe I'm just missing something obvious as this is my first time trying to get an AP to talk wireless-only to a wireless capable internet gateway device (the SA520W).
Currently I have an almost pure N environment, with the exception of 1 printer. My primary router is a WRVS400N v2, and the WAP 4410N is acting as a repeater. On the WRVS400N I have the option og g/n Mixed (which is what I use), but this option is not available to me with the WAP4410N.It seems like the WAP4410N is taking an all or nothing approach, as each speed is idividually available, or ALL speeds are available.What I would like to know is if this oversight will be resolved in a fufute firmware release so I can have both devices configured equally?
I just bought the Cisco E1200 about two weeks ago to replace an older Linksys non wireless router. With my old Linksys, I had an Acess Point installed, a trendnet TEW-638APB. Now that I have the new Cisco E1200 which itself is wireless, I'd like to add my TrendNet Access Point to the netowork and extend the wireless range. However the place in the house I want to put it does not have any CAT-5 cable running to it so I'm trying to set up a bridged connection between the two. I'm a bit new to netoworking stuff but I catch on pretty quick. I've been doing research on it all day between the TrendNet AP and the Cisco E1200 but I'm still a little lost. I've got WDS enabled on the TrendNet AP and have the first MAC address set to the Wireless MAC address of the E1200 but I don't get what to make the next three MAC address. Somone told me to make all 3 of them 00:00:00:00:00:00. Is that correct?
I also have both the E1200 and the TrendNet AP set to the same channel, both are on a 20Mhz channel width, Both have the same SSID though I'm pretty sure that doesn't matter in the long run from what I've read. Also, no incryption on either (no need for it out here).So I guess I'm just wondering how do I use the E1200 as a Wireless Base Station? If that's what it's called? I have upgraded the firmware of the E1200 from 1.0.00 to 1.0.03 but that didn't change anything in regards to seeing an option for a bridging mode or anything. Other than that I'm not sure what else to do.
I currently have 1 AP connected to the router via copper. The AP to AP link is over 802.11. I have attached a diagram reflecting the current topology.
The AP-to-AP link will come up utilizing B/G/N mixed mode; however, the connection is basically unusable. About 30% of the traffic is dropped, while the packets that do make it have a consistently volatile latency, anywhere from 15 to 1500 ms. I have had success using G-only and B/G mixed. The link is stable (I have had the best results with B/G). The problem is, I didn't buy the 2nd 4410N to run the G protocol. I would like to connect the APs running either B/G/N (hopefully negotiating to N) or N only. I am wondering if there is a certain configuration I can utilize (perhaps using WDS repeater or bridge versus Wireless Client/Repeater?), or a firmware upgrade set for release that can make this happen for me.
Ive been trying to figure out what is wrong with this MGX8950 for a while now, it keeps repeating...(i attached a longer file)Also, Ive tried 4 different PXM-HD backcards and 3 different PXM 45/C. I even went as far as dismounting all of the linecards and using 2 different UI-S3 cards.This item was shipped to us via freight on a pallett and all we know is that it came out of service from somewhere that was using it.
My customer is seeing these Errors coming up on one of his 2504 WLC's (ver7.3) The MAC's and IP addresses Mentioned seem to be completely fictitious as the customers IP plan is way off these subnets and the vendor lookup tool cant resolve the MAC addresses.I can confirm that there is no conflict.I've seen them appear on other 2504's across his network on seperate occasions.
I am using 2 anchor controllers 5508 as DHCP server. Anchor controller A is primary and anchor controller B is secondary. From time to time, client will complain "duplicate IP address error" when they try to connect guest wireless.First question: both anchor controller should have a recorder of IP address which is assigned to each PC, right?Second question: is there any way this type of issue can be avoided?
I am getting the following error messge on Cat4500:
Feb 18 23:37:53.098: %IP-4-DUPADDR: Duplicate address 10.237.66.3 on Vlan601, sourced by 001d.096b.4858 Feb 18 23:38:58.092: %IP-4-DUPADDR: Duplicate address 10.237.66.3 on Vlan601, sourced by 001d.096b.47ed
I have multiple wireless access points plugged into a 3560X. When the wireless clients begin roaming they cause duplicate MAC enteries to be created and this causes the switch ports to flap. Is there a way to configure the switch to either ignore the duplicate MAC enteries on the switchports that have been connected to the APs or is there a way to have the ARP tables update and resolve the conflicting MAC enteries with out causing the switchport to flap?
I have a WLC 2504 with 5 AP licenses for which I have installed an adder license via GUI. The installation completed successfully, but I still cannot view the new license. The maximum number of APs is still showing as 5 and in fact I cannot add more that 5 APs. I tried installing the license file again, but now I get a "duplicate" error.
In the process of setting-up a E2500 Linksys router, I set-up my secured network which is working fine but also (I do not know how I did this??) set-up the same named network but it is unsecured. How do I delete this unsecured network.Do I need to set-up the router again?
I'm using .01 firware and I notice that after I reboot the router I get duplicate filenames on the HD attached to it with the video files. What folder or config file can I delete so it will do a clean rescan? please fix the E4200 media server in .02 firmware
I'm seeing a TON of traffic in my ASA logs (via ASDM) indicating the following:"Duplicate TCP SYN from inside: (valid internal address of one of our laptops)/50164 to inside: (address on our other subnet, still trying to trace it)/9100 with different initial sequence number"This looks like an attack to me, likely someone's downloaded something they shouldn't have and got an infected laptop. Why it's trying to "call home" to something inside our network is what puzzles me, though.Is there any VALID reason I would see these sort of messages in my log?
We have LMS 4.2 installed and added devices;Now if for example a device is not reachable we get two messages with same failure ;only the component name is different
- one event with "dns" in component name - one with "dns(ip)" in component name dns == hostname
Everyday a few of the computer will error with "A duplicate name exists on the network:" A quick Google search shows the same answer EVERYWHERE on the internet. So I changed the names of a few of the computers too something I knew was unique. Still though the problem persists/ it afters the two XP bases computers the most, but my main workstations (windows 7 sp1) has had this error a few times, although it appears to have left for a while. I have a feenas server but Active directory is not turned on.My router is a e4200. I was using DHCP server on there (and would very much still like to) although I have turning it off, rebooted both the router and the computers but to no avail.
I am having peculiar issue in my setup. I recently replaced my ASA 5505 (8.2.1) with ASA 5510 (8.4.3). Everything works fine for a while suddenly I see some of the servers will not be reachable from the LAN all the servers gateway is my switch. If I check on my Dell switch the particular server's arp entry on the connected port is same as ASA physicall MAC. If im reverting to 5505 ASA everything goes smooth without any issue.
I got some issues with my CISCO ASA, the thing is that when I add a new rule on the device this rule duplicate and goes to the bottom. We already tried to delete the duplicate rule but it always show an error.
In case I configure duplicate IP addresses to the same VLAN(two interfaces in VLAN 1100 have IP address 192.168.2.2) I see following ARP messages rapidly(those six messages were received in less than 2ms time-frame)
I have just moved to the 3750X switch and have connected it to a 6509E. From the beginning I was having OSPF encryption errors, followed by flood warnings, LSA issue's, duplicate IP's which is baffling me.
There are no IP's which match on either switch however the 3750X was continually power recycling causing the interfaces drop continually.Even after disconnecting from the 6509 the 3750X continue to behave in the same manner. Could there be some issue with this switch?
I have a duplicate router ID problem that is confusing to me. A 6509 and 4510 swich both show the same router ID, but only the 6500 has the router ID IP address configured in it. We are running EIGPR. The 6509 has L0 as 164.72.239.1 configured, which is it's router ID. The 4510 doesn't have 164.72.239.1 configured on it, yet that's what it's router ID is. Below are a few show commands displaying this - and as you can see from the 'show run | include 239' from the 4510 there is no 164.72.239.1 configured on it:
6509 chassis
interface Loopback0ip address 164.72.239.1 255.255.255.255end RS6509-Core-A#sh ip eigrp topIP-EIGRP Topology Table for AS(1)/ID(164.72.239.1) Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply, r - reply Status, s -
[Code].....
why the 4510 has that router ID?
I know I can configure a different router ID on the 4510, but I'm curious as to why it is the way it is.
