After some time LMS stops to refresh network topology (not changing colors for devices which lost/found). However, if I restart topology services devices are refreshed.
Checked the processes. Everything is fine but there is a process named "1018". But I did not found any job with this number.
I've been having a problem with my wireless network connection. Whenever I try and hit the Repair function,it will get stuck on Renewing your IP address for a moment, then change to: Windows could not finishing repairing the problem because the following action cannot be completed: Connecting to the wireless network. I have internet connection on this same computer.Another point to make is that when I click Repair and navigate to the Network Connections window, then hit F5 ( refresh the window ), the wireless connection will quickly refresh and connect normally without error.I won't have to open the Network Connections page and hit F5 anytime I need to repair the connection? Also, as of right now, it's still "Acquiring network address" even though I'm connecting and typing this message.

View 2 Replies View RelatedWe currently support a third party VOIP software. Recently we have had issues with our T38 faxing to our SIP Trunk provider because our FW (sonicwall) doesn't support Nating the connection address within the SDP packet of the T.38 reinvite. This has caused us to look at alternate solutions. I have been in discussion with CISCO sales engineers and can't get a straight answer on which one of their products support this(RFC 3362, T.38 protocol used by our VOIP server)We were looking at replacing our sonicwall with an ASA but it seems it doesn't support RFC 3362 either . However, the sales engineer thinks that their regular routers will. So If I purchase a cisco router, i.e 8xx or 2621XM the question is where do I put it in my current topograpy. Currently we our at a Datacenter and our drop into our cabinet comes right into the Sonicwall and we have all NAT handled there, routing to different LAN ports on the Sonicwall. On LAN side all we have are standard switches supporting all of our Servers.
If I buy a Cisco router to handle my NAT issue for faxing.Do I put it on the WAN or LAN side of my FW?Do I setup the router to handle all of my NATing or just the NATing of my VOIP server that is having issues with the T.38? Would I need a Sonicwall FW if I purchased a CISCO 891?
As we know when multiple PCs share same link"line" they will need multiple access protocol like CSMA/CD to protected from collision,,share link like "bus topology" need multiple access protocol "CSMA/CD" but in star topology"switch not hub" PC0 connect to port0 ,,PC1 connect to port1 PCn connect to portn then every PC connect to separate port ,, and the switch mange the network"by using MAC" then why we need to used CSMA/CD in star topology"switch"???
View 9 Replies View RelatedI have 802.1x configured on a 3550 switch with ACS 5.1 acting as the AAA policy server.
My problem is this. When my computer boots up, ACS authenticates the machine to AD slapping me in a guest VLAN with limited access to the network. Once I login though, I reauthenticate to AD via ACS which then puts me into an employee VLAN but my IP address doesn't refresh automatically. I have to run ipconfig /renew to get my IP in the correct VLAN or write a logon script that does the same thing everytime I log in.
Is there anyway for this to be done automatically outside of writing a logon script?
I have a problem where clients cannot roam between Cisco 1231g-e-k9 and recently installed cisco 1242g-e-k9 access points.. On looking at the CDP option on the 1231 and 1242 access points they are all aware of each other. However if I use the Network View option I see a different picture. All the 1231 access points can see each other but not see the 1242's. Network View on the1242 shows all the 1231's but none of the 1242's. The 1231 are running ver. 12.3(8)JEB and the 1242's are running ver. 12.4(21a)JA1.

Even if the clients walks across the whole building, the client will stay at the same place for several minutes. Is there any way to tune the refresh rate? When I push the load button in the map, the clients position will refresh, or it did when I was on the site, now they just test with an application.
The setup:
WiSM 7.0.220
WCS 7.0.220
MSE 7.0.220
They use the API for MSE to get the location information to the external application, and that will show the information on a cisco 7925 IP phone.know a way to increasing the refresh rate?
when using SNMP on our cisco 3845 the traffic logs are set to refresh every 1 second but the data seems to come in 5 sec burst.so does not some a real time status of the interface throughput.
View 2 Replies View RelatedI just got an EA3500 and I guess I don't understand what "Refresh" does when viewing the DHCP client table under the "Status", "Local Network" tab of the web interface, either that or it's not working. If I have active wired and wireless clients and I power off the EA3500, wait a few minutes, then power it back on, the table is blank. If I hit "Refresh" I would expect it to re-populate the table with the connected clients. For whatever reason, it doesn't. I have to physically disconnect and reconnect the E-net cable, or power cycle the wireless client to get them to reappear in the table. Is something wrong with the router or its s/w

View 2 Replies View RelatedRecently my wirless computer has been loading web pages extremely slow. When I download anything the download speed will start at around 2Mbps and then within second drop to 1Mbps then so on untill it's showing a download speed of bytes. Not kilobytes but just the b. Then int will hang up and the download will fail. Sometime resetting the adapter will allow me another failed attempt to download it. Ive reset the router reinstalled the operating system (was due for a fresh install anyway). Still nothing. Adapter shows connection to the router with 4/5 bars and through to the Internet.
View 1 Replies View RelatedDuring the last month or so my internet connection keeps stalling and will not work until I repair the connection, however I am still connected to the network, I just can't send or receive packets. In particular when I am downloading things, it will stop after 2MB is downloaded or 300MB, it just random. After sending/receiving 7,000 packets or 700,00. This only happens to my computer with the wifi adapter. Prior to this I didn't have any issues for over two years. My phone and laptop still connect via wifi to the internet. And the xbox and blu ray player are connected via ethernet and have not had any problems. The log for my router states "deauthenticate reason 3", which I have found to mean "The access point went offline, deauthenticating the client". So, I figured that the issue could be the wifi adapter which I installed on the laptop and that too never had an issue. I used inSSIDer 2.0 to see the close by networks and changed channels to get away from the strongest ones. I tried switching to wireless n only instead of g and n, the problem still persists.
Then I figured the issue must be my computer and no malware, spyware, adware nor any virus was found. The same thing happened while in safe mode. I also tried the winsock fix to no avail, reinstalled the wifi adapter and made sure all firmware for the router and adapter were up to date as well as XP. I also tried with my firewall shutdown but I still loose the connection. So I then reluctantly did a clean install and even with the bare essentials it still stopped working. I also bought a 15ft USB extension to get a better signal but still, even though I have a good or excellent signal I still have problems. My latest thought was this was the only machine running firefox 4 so I went back to 3 and that didn't either. I checked my usage with my ISP and I am no where near the 250GB a month.
My computer runs bit torrent almost all the time, sometimes when I start Firefox the home page google never loads and neither do any other web pages yet bit torrent is still working as if nothing has changed. If I start a download in Firefox come back to the pc a few hours later Google doesn't load but the Firefox download still continues.What causes this is it DNS ?
View 2 Replies View RelatedOn the basement level, and on level 2, I have in wall junction boxes where the Cat5E Ethernet wires come together. There are 6 lines that go from the level 2 box to 6 wall jacks on levels 2 and 3. There are also 6 lines that go from the basement box to 6 wall jacks in the basement and on level 1. There is also a Cat5E line running between the two boxes.I have wired all these plugs on both ends with T568B standard, and in each box they go into a patch panel. I have used a cable tester to test and make sure all these plugs are properly wired. I have also tested individual computers hardwired linked through to my router (without going through switches) and confirmed that they work that way, so I'm pretty sure I've wired it correctly.
At the second floor box, I have an AT&T 2Wire wifi router and modem, with AT&T Uverse service. I also have a monoprice Ethernet switch. In the basement box, I have another monoprice Ethernet switch (link to the type of switches I have is below). The switches are connected together via the Cat5E that runs between the boxes, and the second floor switch is connected to a free port on the back of the AT&T 2Wire Uverse wifi router.These wall plugs are not all currently used. In fact the problem I describe below occurs even if nothing is plugged into the wall plates.My problem is: when I hook up everything, so my wifi router is wired to the first switch, which is in turn wired to the 6 wall plugs upstairs as well as to the switch in the basement, and that basement switch is in turn wired to the 6 wall plates downstairs... at that point when I plug it in, my wifi stops working. Basically, whenever my router is plugged into this hard wired network, the wifi stops working. When I unplug the network, the wifi comes back (I usually reset it, not certain if it would come back just from waiting).
Interestingly, it doesn't necessarily stop working if most or all of the plugs are removed so the network is not connected (for example, if I just go through one plug instead of all of them)Does a network of wired Ethernet, even if not plugged into anything, cause some sort of a load or drain on the router that could make it stop working?
I am having quite a large problem with my TalkTalk connection. Whenever i turn off my computer, internet access stops for the entire network, anyone who is conencted, however, local access is still possible.I am also having a problem with the wireless in my laptop also. Whereas every computer on my network is able to access the router wirelessly, my computer (the one that seems to chut down internet access) won't do that, i send packets, but none are received.

View 3 Replies View RelatedI bought a DIR-655 for my parents after their old router died in a planned power outage. It's a rev. B1 model running the 2.00 firmware. It worked fine initially for a day or two with great wireless coverage, even in the previously low-signal spots in the house.Then the problems started. The router now has trouble loading any website. What you get is instead a page returned from the router saying something along the lines of "network unreachable, please check you internet settings" (I will go there today or tomorrow so I'll update the post with the specific error). Refreshing the page a few times sometimes makes it load, but extremely slow and then the same thing happens again a few moments later. The same thing happens on both wifi and through the router's LAN ports. If I connect a computer directly to the modem it works just fine, as it has always done before getting this router.I have disable QoS, NAT endpoint filtering and the firewall (SPI). I have also set the WAN port speed to 100Mbit/s in the router, to match what the modem is set to (also had issues with the default setting).

I'm having an issue with a 2 week old WMP54G pci adapter. The behavior is as follows: I get a successful connection and excellent speeds, but every 10 seconds it stops transmitting and drops off the network for a moment. Then everything comes right back. 10 seconds on, drop, 10 seconds on, drop.I've investigated possible sources of interference, but there aren't any strong networks coming though on the same or nearby channels. Moreover, other devices sitting in essentially the same spot are connected consistently and show no variation in the signal strength.
