Cisco Wireless :: 2112 - Client Disconnection And Varying Signal Strength
Dec 16, 2012
We are having a 2112 WLC and LAP1042 access points and facing a client disconnection issue. Also signal strength is varying even when client is at steady position. We have a single SSID structure and clients are connecting through 802.1x authentication with WPA2. Access points are joined in H-REAP mode. We also tried by creating a new SSID with open authentication and even on that SSID signal stregnth is varying and client is getting limited connectivity. Attached are the debugs for a particular client and the show tech support for WLC.
I just installed a DIR-601 cascaded with a WiFi G Netgear router. The D-Link is handling DHCP. I am having varying degrees of success with the WiFi signal. One XP laptop gets anything between 80Mbps and 150Mbps (can change while sitting in the same location), while another Win7 netbook does slightly worse. My Son's MacBook Pro never seems to do any better than 72Mbps.
I dedicated the D-Link to 802.11N and only allow these 3 devices to connect to it as N devices. All other WiFi devices are G and use the Netgear G router. I am using WPA2-Personal/AES and Auto bandwidth (40 does not seem to be a choice).Didn't experience such performance fluctuations with the Netgear G router.
I work on an HP desktop that used to be able to connect to the wireless network. We moved offices and and I am unable to connect to the new wireless network.The network used to appear but had no signal strength. Now the network does not even appear.
I have three desktops and one lap. I have TWC RCA modem and cisco linksys router and two usb adapters for wireless connection. situation is this: the modem and router are at one end of the house and one of the pc's is located at the other end. that one gets low signal strength only one or two bars and the internet works slowly to a point it feels like i'm on dial up. I've had people tell me to upgrade the router from wrt45g to n which I did to an e1000, but I still have the same issue. also was told to move the modem and router to the center of the house. but twc says that would not correct the issue.
Something about dividing the mpbs and the farther the pc the lower the signal. so, guess my question would be 1. does that sound correct to you. would it be better to move the modem and router? would it be better to have the one in question wired in? I did try an extender by netgear, which gave more bars/signal strength but but then would not connect to the internet. but I did that before I got newer linksys router. not sure if maybe I should try the extender again, but then the geek squad, when they came an set up the new router, said that it would probably do the same thing.
I have purchased two WAP200 units to act as access point and repeater. AP and repeater functionality works fine.
The issue I am having is extremely poor signal from both units. Even when very close to the WAP200, I get poor signal quality. The range before loosing connection is only a few feet.
I'm using the antennas that came with the box and have tried multiple placements both in my house and in other locations. I have also tried changing several of the configurations without any effect on the signal strength. Older D-link and Linksys routers provide good reception to most of my house from the same location.
I have two AIR-AP350 SERIES AP's. I am receiveing wifi from my friends house a mile away across a valley with clear line of sight. I think there is a problem with one of these units because when doing a link test one unit shows 14% signal strength on either antenna from the remote router and the second unit shows 6% on the left hand antenna and 1% on the right.
My router has wireless capability and the signal inside my home is pretty strong so I have no compaints there. The problem comes in when I use my computer which is located in a shed outside. I get a signal maybe 35% of the time, and even then it's weak. I want to use an access point to allow the computer in the shed to aquire internet access. Do I need to hardwire the access point or can I do it wirelessly? Would a repeater be more effective and which config would be best in that case?
I find myself having to venture out into the realm of wireless (I'm more of a UC/DC engineer...) and i've got a problem i'm trying to track down. Installed two WLC 5508s, WCS, 3502i APs (123 of them...) in a 4-floor high school. What i'm finding is lousy throughput from a lab of PCs with little USB b/g/n adapters. I took my Macbook in and ran iStumbler to get an idea of the SNR but honestly, i'm not sure what i'm looking for.
For the particular room/SSID/band that i was looking at, i found that in the 2.4 range, i was getting 53% signal strength and about 16% noise. Is that a good level? In WCS, i can see close to a dozen APs in relation to the AP in question, so i'm wondering if the SNR is too high..
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.
I am using a desktop PC with a wireless USB stick attached in order to connect to the internet via a wireless router, however, although it states that I am connected with excellent signal strength, it continues to show a warning sign over the wireless connection signal bars ON THE DESKTOP TRAY ONLY. I can't surf the web on my desktop or on my IPAD through the wireless connection in which both devices detect. I have a Sitecom wireless router.

I have an intermittent problem with one of my PCs on my wireless home network. While I always have excellent signal strength, most of the time I can not connect to the internet. All the other computers on my wireless network work fine and I can always connect to my neighbors wireless network to get internet access with the problem PC(A dell latitude E6410 with windows 7). When I have no internet access on my network and I run some diagnostics it says that my default gateway is not available.
A while ago I replaced my wireless card, and the new one get's considerably weaker signal strength and drops out periodically. I'm sure the problem is with the card itself (or its firmware). It not only get's weak signal strength from my router, but every surrounding network, and sometimes can't detect any networks for a few minutes. I've used several other wi-fi devices in the same spot where this system is sitting and they all get excellent signal strength.I've already tried changing channels on my router and re-installing drivers. Neither has any effect.The card in question is a TP-Link TL-WN951N.
I have a wireless network in my home, mainly for internet access via any of the 3 or 4 machines we may be using. Normally, there's not a problem with normal surfing, email checking, youtube, etc.My wireless router is a Linksys WRT300N, and the wireless adapter card in my desktop is a D-Link AirPlus G DWL-G510 Wireless PCI Adapter. In my previous home, the router was in the very same room as my desktop, and had no problems to speak of with this setup streaming Netflix. Now, however, I'm set up in an older home, and the router is removed from my desktop by a few walls and tight rooms. I've noticed that my network status icon on the bottom right of my desktop seems to always show "Signal Strength: Very Low".I like to use my desktop sometimes to stream Netflix. My Netflix streaming sometimes goes OK, but typically it just freezes and shows the Loading bar, and sometimes doesn't really start back. It is so bad sometimes, that I am not willing to wait it out, because I know from this experience that even if it starts back up, it will just freeze again. The video is not downloading and caching fast enough.
My wireless router has been spotty since my cable company installed a new modem for cable internet. I have powercycled several times, downloaded new firmware, rebooted and am still having problems. Lately when I do finally get on the internet with a wireless device, the signal strength is very low. It is low on my iphone, on my Mac laptop and also on my Samsung Bluray player. Lately a window keeps popping up when I am trying to watch netflix that states my band width is too low, even though it has been working fine for 2 months. Is my router outdated?
I have a WET610N on my network with very little signal strength. My set up is:
Router E3000 48 ' (48 feet) to WET610N
The WET610N is on 5Ghz N, and is the only device at Ghz, and indeed the only wireless device during testing.
The use for the adaptor is to connect an Xbox 360 as a MCE for Video streaming.It is unusable, with unwatchable lags and intermittent failures.The 'Network Performance Monitor" doesn't read in mb/s, but essentially I get about 1 or 2 'bars', well under the acceptable for Standard def reading.
zInterestingly, when I bring the device within 3 feet of the router, I get great speeds (30 Mb/s down), but the bit rate reading in the status screen reads lower than the below reading.
Below is at the 45 foot mark->
Link Status:Connected MAC Address:68:7F:74xxxx:31 Network Name (SSID):sx BSSID:98:FC:11:xxxx9:94 Radio Band:5 GHz Channel Width:20 MHz Wide Channel:N/A Standard Channel:36 Bit Rate:43.3Mbps Signal:10% Security:WPA2 Personal
Currently I'm using one e4200 (v1) as my main router in the house. The wireless coverage downstairs is perfect, but upstairs the signal is weak. To improve this I thought about adding the WAP610N as an access point to my network. But this device gets quite some negative reviews ... Thus I was thinking why not add another e4200 (v2) to my network? The price difference is not that big, especially compared to other simultaneous dual band access points. So my question is, would following scenario work?
- first e4200, connected to my ISP, acting as a router, using both the 2.4 as 5 ghz band (basically my current situation)
- second e4200, connected (via UTP cable) to the first e4200, in bridge mode
- second e4200 also using both 2.4 and 5 ghz band, using the same SSID, security etc but a different channel
So when moving a laptop for example from downstairs to upstairs, automatically the router/access point with the strongest signal would be used.
We have a new e1000 router that was having trouble reaching the TV for Netflix movie streaming. Too many walls and too much distance. A simple solution was to direct the signals from the router by placing aluminum foil behind the router so all the signal was going towards the TV rather than in an 360 degree circle. Now the streaming works great! After the movie is done I remove the foil and everything looks just like it should.
I have a new e3000 series router and on all pc's I'm using model AE1000 receivers. Now, the laptops we use work great until we go out to a room built off the main house (a seasonal porch)
I have configured a new LinkSys e3000 as as wireless router in our house.I have left the configuration as default (only secured it and turned on the DHCP server).I have only turned on the 2,4 GHz network ( because the 5GH had an even shorter range).Everything works and all my devices can connect to the router and access the internet.However i find the signal strenght of the router to be very poor.Already in the next room it drops to 60%. And in some rooms on the 1st floor the signal drops completly.This happens not even 20m away from the router in an ordinary "family house".Is there a setting somewhere which could increase the signal strength ?I noticed that the router has no antenna, can one be bought and attached so the signal increases ?The firmware version is 1.0.02 and i found a newer on your web 1.0.03. How to improve the signal strength?
I have a two story house with a basement. Right now I have a Cisco Linksys E4200 router on the second floor in one of the bedrooms. I have a DLink GamerLouge 4500 in the basement. Both systems have the same SSID and are running on different channels. Computers connect to the appropriate one automatically. At least assuming that's what's happening.I am getting limited connectivity on the first floor in the kitchen and family room. Dining room, right by the second floor stairs is fine. All the bathrooms are dead zones. Note I have thick travertine tiles on the walls in the bathrooms so may inhibit signals. Trying to figure out the optimal solution for getting the house setup so everywhere has at least decent signals. I have alot of iPad and laptop devices floating around the house so wireless is key. Note I have wired plugs with Cat5e all over the house to a central hub in the basement which is where the DLink router sits. Thoughts on how to improve my signal strength? Especially in the farther reaching bedrooms and the first floor
I have already seen many threads with the same problem but none of the solutions worked for me.I am unable to connect to my router (Beetel 450TC1) via wireless network. Even if I enter an incorrect security key, no authentication error is displayed. The wired connection works flawlessly and I can access router admin panel through wired connection. Things I have tried:
1) Called up the ISP customer care.They upgraded the router firmware, did a hard reset and did all settings remotely. This did not fix the problem and the executive reported that I have a faulty hardware. I think my hardware is fine because the same problem exists with other smartphone devices and I can connect to college WiFi easily.
2) Changed wireless security authentication and SSID.
3) Tried a manual hard reset and firmware downgrade (same problem persists with downgraded firmware) and again upgrade.
4) Tried different operating systems (Windows 8, Windows 7, Ubuntu 12.04). Same problem exists with each of them.
On my asus laptop, wireless does not work. It works when connected with ethernet cable. Signal show wireless strength excellent but it does not work wireless.
I have a Linksys E1000 router. The macbook is getting great signal even out in the yard. The PC running Windows 7 and using an AE1000 wireless adapter is only getting 2 bars out of 5. I don't think there's any interference. I can't figure out why the signal strength is so poor.
Region : Denmark Model : TL-WDR4300 Hardware Version : V1 Firmware Version : 3.13.23 Build 121225 Rel.37950n ISP : Fullrate
No matter what I try, the signal strength never gets better that 30%, even when I have my laptop next to the router. I have tried various settings (found in these forums), but nothing seem to work. My old D-Link performed better, both close and over distances.
I've noticed something interesting, after having been disconnected from the WLAN in less than 1 minute in my first experience with this Linksys' Modem Router: The signal strength was poor when browsing the Wireless LAN. I was at home, in a room just beside the one where the router was placed at.So, I took a look at connection status, and saw the signal strength was Medium - Weak: something around 30% and 55% You could think it was due to mirrors, the kind of walls between the rooms, and everything else, but I instantly remembered when browsing WLAN from the same place but not with the same router, the signal was strong (100%)...but I let it alone In the other day, while browsing WLAN, I've noticed another thing, this time visible: "TX power" I've got in connection status was 39mW, while I was almost sure it should be 100mW, based on my past WLAN connections Then, today I decided to take a look more deeply in that, and unboxed my Linksys' WRT54G to test. The test was carried on consisting in both Wireless routers placed in the same room, and a solid wall was between me and the routers.I could connect to the two WLANs, but the status of connections were different.
WAG120N:
WRT54G:
As you can see, when connecting to WRT54G , signal reached 100% at some point, whereas in WAG120N , such a mark wasn't possible.Of course, the signal strength was unstable in both routers, but the average level in WRT54G WLAN was greater, being most of time over 90%, and never below 80%.In WAG120N WLAN, average was 82%, and lowest level was 55%.When I went to the room where the routers were at, and right in front of them, no need to say both reached 100%, but as you can see, in WAG120n's case, TX power was still 39mw: I believe it's a firmware fault, once all other routers I've connected to always showed TX power as being 100mW.It shoundn't be related to the general hardware, as Cisco products are high-quality ones.
For some reason my ps3 wont connect,the signal strength is 100% but it just times out.it will randomly connect BUT cant stream anything or connect online.Or it will get disconnected if someone turns on my mine computer in the other room/Should i DMZ the ps3?Routers a WRT610N dual N Firmware Version: 2.00.00 B05 cant upgrade to 3.00 because of "upgrade failed" error.

When I'm not connected to my wireless network, the signal strength is 4 bars (out of 5)Once connected, it drops to 2 bars. Speed is 39 Mbps. Why?I have updated the drivers (strangly, it says the drivers are from Ralink Technology. Corp, version 3.00.00.0041 built by: WinDDK)
What signal strength should I expect when in the same room as the e4200 ?I'm checking signal strength with iStumbler and with option-right click on airport menu icon on my Mac.I'm getting a signal strength of about -55 while in the room with the router.What signal strength should I expect while in the same room, no physical obstructions, etc. ?
I have a E2500 router and just got this AE3000 adapter. Thought that would bump up the wireless signal for using my laptop at the other end of the house about 75 feet from the router. The new E2500 Wireless N has been a big improvement. The AE3000 installed perfectly and shows up as working properly. It's just that the signal strength on my laptop shows 2 bars and the signal strength for the adapter shows 2 bars.
