I have the DIR-655, Rev. B running 2.07NA firmware, and have a strange problem with my wired clients. I have my primary computer/desktop PC connected via wired connection. I also have several wireless clients (laptop, iPad, iPhones, etc.). All have been performing normally. However, in December I connected a wired weather internet bridge to another ethernet port on the DIR-655.
It functions as it is supposed to, and all other connected devices do as well. But here's the problem - whenever I use the desktop PC (the only other wired connection) to do anything on the internet (mostly just web browsing ... I don't stream media from the internet on it, I don't do torrents....nothing out of the ordinary, and nothing really of high bandwidth), the wired weather bridge cannot communicate with its associated website. This continues as long as I'm using the desktop PC. When I stop using the desktop, the weather bridge resumes normally.
I have researched the weather bridge, and it is simply doing POST transactions (or so I'm told) to the website listening to it. It doesn't wait for acknowledgements or anything...just keeps POSTing updates. I tried reserving an IP for the weather bridge and the desktop, enabling QoS, and prioritizing the weather bridge (100 vs. desktop at 125), but it didn't work. I've tried moving the weather bridge into the DMZ. I'm totally baffled how just using the desktop to browse the internet could completely block the traffic from the weather bridge.
On the weather bridge support site, they suggested that I insure I'm not connected in gigabit speeds from my computer to the router, because in the past that has been known to cause issues on clients not running that speed, but I don't think my desktop is connected in that fashion. According to the settings, it can do 10 or 100, full or half. I have it set to AUTO.
I am troubleshooting interface resets on a 3660 connected to a 3550 over Fast Ethernet. I have hard coded both sides for full duplex and 100Mbit. The 3660 is incrementing interface resetes about 4-6 times a day and the 3550 is clean. I have noticed this in other similar configurations as well.
View 4 Replies View RelatedI recently purchased a DIR-815 and am currently trying to use the 2.4 GHz Wireless mode so I can connect a remote WiFI product to it (approx 30 feet separation) to get access to the internet for sending email and to FTP data from the remote WiFi product over the internet. It is imperative that this connectivitiy be reliable and continuously accessible. The PC host and the WiFI product are unattended and require 24/7 use and conneciton reliability.
My problem is that for no apparent reason the connectivity to the DIR-815 by the PC host (wired to DIR-815 by ethernet) is not reliable....and even though the connection is obviously lost, my PC thinks it is still connected according to the Network status info shown in Windows. I then have to do a Network Repair on the PC to get the connection back. Whenever this is happening during the loss of connectivity by the PC to the DIR-815, the WiFi connection from my remote WiFi product is also lost which we cannot tolerate.
PC host is connected to DIR-815 via ethernet cable. DIR-815 is connected to a ViaSat Surf Beam Satellite modem (model SM2100) that is accessing Big Blue sattelite service as the ISP. I have the DIR-815 using 2.4 Ghz channel set to WEP2 TPIK-AES security. When connected everything works fine. We just need it to stay coonnected without having to be rebooted all the time.
Is there any way to resolve this problem and improve the connection reliability of the DIR-815?? I wish there were some way to send a WiFI command from our remote application to the DIR-815 to reboot it, which we could program into the remote product, but when wireless connectivity is lost, obviously that is not possible.
I am using 3660 Router, all cards are working fine as expected but NM-2FE2W is booted & then down. Following error is occurred in show diag "Port adapter is disabled deactivated".I have reset the card as well as router, changed the slot of card, but the problem is not resolved.
View 8 Replies View RelatedI was very happy working with my WRT610N connected to the ethernetport of my previous internet modem. Recently I had to switch to a new modem CISCO EPC3925. Unfortunately this combination does not work anymore. I don't get an internet connection on my WRT610N anymore. I therefore have to connect all computers (LAN and WIFI) to this EPC3925. Especially for the WIFI I'm not fully happy. My IPAD2 sometimes does not want to connect, a problem which never occurred when connecting to WRT610N.
I probably need to change a setting, but where? In the EPC3925 or in WRT610N?

Here is my setup:
TWC / RR cable modem to 655
655 port to xp machine
655 port to voip adapter
655 wireless to 1522
1522 port to xbox 360
I am no guru but managed to get all this working about 6 months ago. Other than some TWC outages it has been fine.Couple days back the XP stopped seeing the net. It could still see the LAN. The voip adapter and 1522 / xbox 360 still work fine.Here is what I have tried:
Plugged XP in 1522, worked fine.
Plugged XP directly into cable modem, worked fine.
Plugged XP into port the voip is working on, did not work.
Tried other 3 ports on 655, did not work.
Since the XP machine works with the 1522 and cable modem I am assuming the XP machine is not the problem.Since the voip adapter works on the 655 ports I am assuming the ports are not the problem.
I installed the DIR 655 router using the install disk. I hooked up my Vista desktop machine via the ethernet port. I also activated a Roku box and my Itouch successfully via the wireless.I turned MAC filtering on and manually entered the MAC addresses for the three devises. Everything worked fine.After I rebooted the desktop, I could no longer get to the internet via the desktop connected through the ethernet. The Roku Box and I-Touch both work fine and enjoy a strong wireless connection.I've tried rebooting the desktop several times, but still can not access the web. I also can not access the router by typing in 192.168.0.1. I entered the configsys stuff and verifited that I am using the right numbers.

View 1 Replies View RelatedDuring an installation, we plugged a Ruckus wireless bridge (powered by a PoE injector) into G0/0 on the 1941. The port status remained down/down. We then tried connecting it to G0/1. Again, the port status remained down/down. We took another wireless bridge, plugged it into G0/0 and the port changed to up/up status within a few seconds. The same happened when connected to G0/1. Both ports are have speed/duplex set to auto/auto.We took the cable from the first wireless bridge and connected it a 3550 switch, the FastEthernet port went up/up. We then took the cable and connected it to a switchport card (HWIC-4ESW) that was installed in the 1941 router. The port came up/up.We connected to wireless bridge back to G0/0 in the 1941 and manually set the speed/duplex to 1000/full. The link light on the router became illuminated after a few seconds but no console message was displayed (nor did any events appear in the log) and a "show int g0/0" showed the port status as down/down. This was could not be duplicated as this only happened one time The wireless bridges sit atop of a water tower and are connected each via a shielded ethernet cable. The cable that we're having trouble with is cat5e STP and about 310feet in length. I should note that we have not yet swapped the PoE injector but it seams to be functioning properly as power is getting to the wireless bridge and its accessible. Also because if the wireless bridge for some reason didn't come back up after a power cycle it would potentially mean climbing the tower to perform a hard reset. We tried another 1941 with same results however we have not tried another router model to rule out a potential platform issue. Can you recommend any troubleshooting steps to determine why the port status of the gig interfaces on the 1941 don't come up?

In 2008-2010 timeframe, I used the ace 4710 appliances at one customer and kind of liked them. The deployment was not too SSL intensive and B/W requirements were low, but I configured a few HA pairs and that worked well. The configuration was pretty comparable to other Cisco devices; so easy to learn/pick-up.Fast forward to 2011: stepped into an environment, where customer purchased 3 - ACE 20 modules (before I got here), and had multiple issues with them. I found 4 documented TAC cases, and 1 was still open. I started working from December 2011 on getting Cisco to own-up WRT modules but customer by that time had had enough.
The most serious issue was a random reboot, hang or lockup. I wasn’t here to work with them to verify, but that’s eventually what the deal breaker was. Around the February 2012 timeframe, talking to Cisco SE, he revealed Cisco had an independent lab in Switzerland verify that some hardware component on the device had a terminal defect, in which a bit would flip, and force the device to lock or reboot - subject ot radioactive decay or interference.Cisco and the lab attributed this to improper shielding, coupled with defective material in the electronic component; hence the device was highly susceptible to radiation-type errors. This is the kind of stuff you read in doomsday reports! As a result, Cisco was EOL-ing the ACE-20 module. I am trying to get Cisco to replace the ACE-20 modules with something else, but they haven’t been too cooperative. They have also limited their SE/Salseperson presence where I work (Pacific Northwest); and are not too responsive.
I have gotten a verbal agreement to get a credit on prior purchases for the amount this customer spent on the ACE-20 modules. However, the credit is only a few points off their normal discounting model. And Cisco will not go into loss on new product sales. Using example, $100 product would cost me $55 with standard Cisco discounting. Cisco’s cost might be $45 so I will only get another $10 credit on this new purchase.The 3 Cisco ACE-20’s originally cost customer about $100K, so to dwindle this credit down, we would need to purchase about $1-$2 million of new hardware - that's a lot of new gear! And I don’t have any real way of knowing that Cisco is applying the credit honestly, and they won’t put anything in writing. This entire issue has really dampened customer’s impression of Cisco. They had smartnet on the ACE-20’s for 2+ years, but then dumped that after losing faith in the product. Now I am trying to resurrect smartnet to see if Cisco will give us an alternate product.
And to cap it all off, the original Cisco salesperson (who sold customer the ACE’s), has left and went to work for F5! And yes, he has been calling on customer to try to sell some big-IP's! At least there is some humor in all of this. So... Has anyone else had bad experience with ACE-20 module? How about ACE 4710? How to get a reliable working ACE module from Cisco?
My company has a cisco ASA 5510 and we have a Citrix remote desktop solution. In a nutshell I have users from outside our network accessing a virtual Citrix NetScaler inside our DMZ. There is a session reliability feature enabled on the Citrix solution. Session reliability uses tcp port 443. A user from outside the network connects to our network and is handed a virtual desktop to work with. When a remote user is working on their virtual desktop and there is a network connection issue the end user loses network connectivity for a brief period of time (in most cases just seconds) then the Citrix session reliability feature takes over and holds in a buffer all data destined for the end user . Once the connection is re-established then the buffer is emptied and the session goes on like before and the end user is able to use the virtual desktop. At least this is the way it should work.
In our case the connection never re-establishes between the end user outside the network and the NetScaler in our DMZ. We have been working with Citrix Support and they believe the issue is in our firewall. We have taken packets captures with Wire shark and we can see when the network failure occurs the NetScaler in the DMZ is holding information in a buffer and trying to communicate with the remote end user outside our network via packets and TCP port 443. We can also do the same packet captures from the end user computer and see where it is not receiving any packets from the NetScaler in our DMZ. The fire wall has an access list allowing any traffic in the outside port destined to the NetScaler Public IP on port 443. Then once in the firewall outside port we have a static rule pointing to the NetScaler IP in the DMZ.Everything is working quite well until we need to rely upon the session reliability. We have tried altering the TCP & Global Timeouts options in the firewall via the ASDM with no luck.
I've had trouble connecting to my own internet and have no wireless. I'm using my neighbor's wireless and it's really slowing her's down.

It could easily be -30F for several nights in any given winter. I am going to spend about $1,000 for two cams + cabling, etc. running into a PC to record video events.

I have a Dell XPS M1530 with Vista 32 bit. When i plug in a cable i get nothing, no error, and the comp does not recognize that a cable has been plugged in. I think that this started after my Hard drive failed and Dell replaced it but i'm not positive. No errors (? or !) in Device Manager and I can't find the Marvell 88E80XX 10/100 Ethernet Controller in device manager. I have attempted to Reinstall the drivers. The wireless is still working. I have one Light to the right of the port that is on all the time solid but no flashing with the cable in or out.
