SA520 and Lan ports problem

I would like to ask for your help. I have a Cisco SA520 with the latest firmware and I am experiencing a problem with the lan ports. After a minute all 4 lan ports are dead and are not working. although when you open it they are working after a minute they are dead. What you suggest to do.
Thanks in advance Konstantinos

Good morning
Hi Konstantinos, thanks for using our forum, my name is Johnnatan and I am part of the Small business Support community.

Problem 7911 and Lan port PC

I have a problem with IP phone 7911, when I connect a PC siemens on the Lan port of the 7911, Lan does not go up.
If I put one 7940 A the place of the 7911, it's ok.
If i connect a PC Siemens on the lan switch, it's ok.
My Ip phone 7911 is with a firmware 7.1.11

I think this is due to hardware problem on 7911 ip phone

DHCP on both Wifi and LAN ports?

Everything works well; Wifi clients (MAC only), AppleTV, USB Hub with Printer and 3 External disks etc...
I plug in my MacPro via a LAN Cable and it does not get a valid IP Address from the DHCP server.
Tried setting a fixed IP with all the proper config, nothing gives.
I am a tried and true IT professional with over 20 years, and can't figure this one out. Anyone else have this problem?

That certainly should work. The AirPort Extreme base station (AEBS) supports both wired clients (via the LAN ports) and wireless clients. All clients appear on the same subnet.
The MacPro has 2 Ethernet ports? Have you tried both of them? Check the Network preference pane to ensure that the one you are using is enabled.
Otherwise... have you tried using one of the other LAN ports? Have you tried a different Ethernet cable to eliminate the possibility of a defective cable?

Via Controller and Lan port

Hi all, first the bad news, I was OC'ing as a Sergent...one day I booted up and the system saw the Drive, but no windows(just a black screen) so I assume I lost my array. I was using the Promise controller, no issues until then. Now the problem, I am attempting to use the VIA for Raid0, it sets up great, but I can't seem to get the on brd LAN port to work correctly. If I re-install using the Promise..no issues...I know I am being somewhat vague..but I have never dealt with something like this
Ideas???

Hi jocko, thanks for the reply! Yes i did, it's really strange I send packets but the system will not receive. I really doesn't make since. Also before I lost the Raid I was getting weird questions on bootup , the system was starting to attempt to use the LAN boot mode even though I had never used it, it just showed up one day, then I got the error about having to restore the system, the next day I had nothing....I also ordered the nvida chipset brd today....

I want to know if Ican connect a print server (to print with several wireless printers) to the new airport express given that it has wan and lan ports. Tks!

The print server that I want to connect allows me to choose among 2 usb printers and 01 serail port printer. It needs to be connected to a router through a lan port. Given that the all new airport express now come with a wan and a lan port, i want to know if I can connect this device to the airport express.

You're welcome.
Beware that while USB print servers are commonly available and inexpensive, finding one with a serial port is more of a challenge. Apple Stores in the US do not sell them. Call the iStore before going there.
If you need recommendations for obtaining a print server with a serial port, let me know.

K8N Neo4 (MS-7125) USB, Mic, S/P Out, and LAN ports all non-functional

I'm hoping someone can give me a hand with this. I'm not a novice when it comes to motherboards but this particular board is making me feel like it.
Ok, I've got a K8N-Neo4 MS-7125 model. Athlon64 3700. I have all the current drivers and ran the liveupdate to make sure.
The LAN port will light up, but the Device manager will not recognize it, nor will the LAN utility.
The board has 4 USB ports. The top two are non-functional, the bottom two work.
The S\P OUT port has never worked, nor do I know how to engage it or find it on the device manager
The microphone....this one is fun. Its like the microphone is stuck in a feedback loop. Whatever comes through my speakers, is heard on the other end by other users. I am not heard at all, although I can hear myself through my OWN speakers. Even with the mic unplugged, people still can hear my speakers. Imagine having your speakers plugged into the mic jack. The only way to kill the feedback is to actually go into the sound manager and mute the whole mic system.
I can live without the LAN and USB ports, but it would be a HUGE help if someone can help me with the mic and S\P ports!!
Thanks!!!

Ok, I'll do my best to remember everything
Athlon64 3700 939socket
XP Pro Service pack 2
Rosewill case 400watts

GEForce 7300 256DDR (PCI Express)
120GB Seagate 7200 RPM Harddrive (IDE) Partioned two drives
1x512DDR ram PC3200 400mhz
As for the flavor of the NEO4 the only other numbers I know of, is on the board it says N1996 right below the processor. Is that what you need? Its a PCB V.3 board nvidia Nforce4.
Speakers are standard cyber acoustic
Logitech Mic/Headset combo
This particular case allows for hookups for headphones and mic in the front. The case has jumpers in the back that allow you to gain access from the front (but you probably already know that). I've always used the front MIC/Headset jack, and I have a splitter in the back for the headphones and that jumper. In trying to resolve the issue, I tried every jack with the microphone (even the ones that I know are labeled as speakers). I do get my own voice through MY speakers on the front jack AND the mobo jack.
Hopefully I got you enough info!
Thanks in advance!!!

Time Capsule's LAN Port Problems

Hi, y'all!
The LAN ports on my 1TB Time Capsule died last week. The status lights would not come on at all on any port. My iMac's Ethernet port could not see a connection.
AppleCare sent me a refurbished unit earlier this week, and it was working great. But this morning, when I woke it from sleep, the replacement unit would not connect over Ethernet. The three LAN lights would not come on, and the iMac could not make a connection. I rebooted the TC, and they came back, but 30 minutes later, I woke it from sleep and saw the LAN light turn off as the iMac came up. I moved the cable from port to port to port, and one finally came on. But this does not seem normal or acceptable.
Has anyone else had any trouble with the LAN controllers on their Time Capsules?
Thanks!
Jon

Thanks for your responses! Nope, I'm just using regular, straight-through Cat5 cables. Definitely a good idea to keep that in mind, though!
I believe the Time Capsule and Airport Extreme both have Auto-MDI/MDX, but I'm not sure.
My TC's LAN ports are behaving today, so fingers crossed.
Thanks!
Jon

SA520 optional wan port problems

Hi,
I've got some problems activating my optional wan port...

Itunes 7 and USB port problems

I recently upgraded to Itunes 7.0.2, and have been trying to get it to work with my 60GB Ipod Photo. With Itunes 6, I could connect my Ipod via USB with no problems. With Itunes 7, my Ipod will connect perfectly fine. When I attempt to update my Ipod, though, it will sync a couple songs and then say that my Ipod is corrupted. I forget the exact error message, but the gist of it is that Itunes won't write to the Ipod because it thinks it is corrupted. Syncing through Firewire works perfectly fine, though. Firewire is a pain for me, so I would like to get my USB connection working again.
I am running WindowsXP with Itunes 7.0.2 and using USB 2.0. Any help you can give me on this would be greatly appreciated.

I'll post my solution in the hope that this helps others. Tech support for Ipod is apparently non-existent.
1. Uninstall iTunes. Completely. This means deleting temporary files and any windows installation files. Also, ensure that there is no iTunes related registry values.
2. Connect your Ipod, go to the disk drive icon corresponding to your Ipod, and right click. Select Properties.
3. On the hardware tab, select the Apple Ipod option and press the Properties button.
4. Select the "Optimize for Performance." option. Hit the Apply and OK buttons until you've gotten out of the dialogues.
5. Restart the computer! This means turn it off! Do not just hit the restart button! Then re-install iTunes.
Although I doubt Apple reads this stuff, this will be my last Apple product that I buy. I find their lack of software support appalling. On top of that, they seem to only produce buggy software and unstable hardware. For $300 I expected something a little better.

Input and Output Ports Problem

Hi,
I have defined an IView where I defined the Outcome to an OUTPUT Port EMP which sends Employee Number.
And I had defined one more IView where it starts from an Input Port EMP, which takes Employee Number as Input for the RFC Enabled Function Module.
Both these IViews are there in the same page. So in the page level I tried defining a link between these two ports of these IViews. But I was not able to do that.
Why is it happening so?
Is it possible to define a link from OUTPUT PORT of FIRST IVIEW to INPUT PORT of SECOND IVIEW?
Can anyone let us know if this is possible.
Regards,
Raja Sekhar

Hi Deep,
Well, I am using VC 6.
And We are on EP 6.0 SP14.
And how to check if these .SDA files are deployed into my PORTAL?
Coming to EPCM values of both the PORTS...
com.sap.visualcomposer:epcm
Both have the same value.

Lan and Wan port on Airport express

Hi guys I am wondering if you could help me out with my airport express.
I recently bought an airport express and have it set up as the following:
Router--->ethernet cable in to the Wan of Airport express--->ethernet from Airport Express Lan to computer
This is so that I have hardwired internet to my gaming computer and wifi in my room for all my devices. The problem is, however, next year I will not be in a situation that allows me the same setup. I will be too far away to run an ethernet cable from the router to the airport express. So I have decided I shall use it to join the network wirelessly and relay internet through both the Wan and Lan port (think this is called bridge mode?). I was also intending on connecting an ethernet hub to one of the ports so that I can connect multiple devices, smart tv, macbook, ps3 etc. But having one of the ports exclusively to my gaming pc.
My question is, with both Lan and Wan ports relaying internet to multiple devices, would I see a drop in performance, in particular in regard to my compter? Or is the airport express able to join both the 2.4GHz or 5GHz and relay each connection to a specific lan port?
Unfortunately I am not in a position to test this yet, lacking a 5GHz connection in my halls, so I would appreciate if anyone could help shed some light.
Thank you

is the main router also an apple product? if so, then yes you can extend wirelessly, but if the main router is an apple product, why are you bothering to extend wirelessly at all when the main router's signals should be strong enough?
if the main router is NOT an apple router, then you wil NOT be able to extend it wirelessly period.
in my experience, there are very FEW places you NEED to extend a network wirelessly, and i always recommend against it since there is a big performance decrease.
In the case of a wirelessly extended network, throughput may be reduced to less than 60 percent of that of a single device.

RV180 (wired only) problems with firmware 1.0.4.14, fails to boot correctly + LAN ports power off during boot (downgrading to 1.0.3.10 = fine again).

Hi All,
A few months ago when 1.0.4.14 was released I was quick to update to this version from 1.0.3.10 but very quickly ran into issues.
Bit of background info... I am not doing anything complex with this box, basic IP4 network over all LAN ports, no VLANs, firewall enabled and allowing 2 port access rules to a static IP address. Any static IPs are assigned manual at host level but all other devices receive DHCP IP addresses. I don’t host VPN on this RV180 but I do with another. Routing VPN has no issues. WAN is connected to another switch provided by my ISP who provides DHCP IP Address with their DNS etc. Only LAN ports 1 and 2 are connected, port 1 to my Wireless AP (AP mode passing all requests to the RV180, DHCP etc.), port 2 connects to a 8 port Smart Switch (but all 'Smart' features are currently not in use, so basic switching only). All other settings on the RV180 are on recommended defaults.
Everything is working fine on 1.0.3.10 but I have all kinds of issues after updating to 1.0.4.14. Here are the actions and experiences I had...
1) Backup my RV180 config to txt file.
2) Navigate to the firmware upgrade page and follow steps to complete the upgrade process from 1.0.3.10 to 1.0.4.14. *router does the normal process of upgrading*
3) RV180 reboots to complete but doesn’t come back up even after waiting 5-10 mins. LAN ports enable during boot up (link lights on) but after about 2mins turn off (no link lights). WAN light is on alongside the Power Light.
4) Power cycle even with rest... Same results.
5) Reset the RV180 to default settings. I can sometimes get the unit to boot up and the LAN remains active and powered up. The web UI is VERY slow compared with 1.0.3.10. Internet sometimes works and sometimes doesn't (I would expect it all work without issue on default settings).
6) I repeat this a few times, various resets, powered off waiting periods, etc. but I always have issues. I did manage to get some log file information and the Kernel appears in the Alert, Error and also the Warning logs (please see attached files).
7) I gave up at this point. No major issues like this reported on the internet from a few google searches etc. So I then reset to defaults (1.0.4.14), downgrade to 1.0.3.10 and finally reset to defaults again + restore backup config settings (with some manual changes).
The router has remained like this and seem to be working fine, but I would like any security improvements from 1.0.4.14 firmware on my device.
Anyone able to help, have the same issue or can advise me in any other ways?
I see 1.0.3.10 isn’t displayed as a firmware download on the standard support page for the RV180 now. Only 1.0.2.6 and 1.0.4.14. Do I need to downgrade again to 1.0.2.6 before upgrading to the latest version?
Regards,
~FAZ~

Hi,
I recently bought a RV180 router and immediately I encountered the same problem; practically I am not able to access the web GUI.
The PC is directly connected to the router, nothing else is connected; the TCP/IP configuration is as follows:
PC: 192.168.1.100
RV180: 192.168.1.1
GATEWAY: 192.168.1.1
SUBNET MASK: 255.255.255.0
Once the router is turned on, the power LED flashes fastly, the Ethernet LED is on but after few minutes it disappears and the PC detects a disconnection of the Ethernet cable.
The router is not pingable and, as I said, the web interface is not reachable.
I have tried to power cycle the router, to reset it (pressing the reset button for more than 3 second and for more than one minute), to access the rescue mode and download a new firmware through TFTP, but nothing worked.
Few times, after many boot and reset trials,I was able to access the web interface and in one of these occasions I updated the firmware to 1.0.4.14 but once the router is powered off the problem arises again at the next power on.
I have not tried yet to downgrade to an older firmware version.
Can you suggest any solution? thank you.

Solve this and you're a genious: Port problems with SRW2016

Equipment:
One SRW2016 fresh out of the box and set to factory default settings
One Dell Laptop running Windows XP
One custom network appliance running a full TCP/IP stack but limited to 10M half duplex.
Setup:
The laptop has a static IP address. The network appliance has a static IP address. The switch has the factory default static IP address. All three devices are on the same subnet.
The laptop is plugged into port 1 on the switch, and the network appliance is plugged into various ports as described below. The laptop is set to continuously ping the network appliance using the ping –t command.
Problem:
When the network appliance is plugged into switch port 2 I am unable to ping the device from the laptop. When I plug it into port 3 I get the same result. In fact I am unable to ping the network appliance on any of the switch ports EXCEPT for ports 7, 8, 15, and 16. As soon as I plug the network appliance into any one of those four ports, the pings are replied to.
My question is - why am I unable to communicate with the network appliance on any ports other then ports 7, 8, 15, and 16? What makes these four ports different then the others?
Other Notes:
I have a second Linksys SRW2016 and notice the exact same behavior.
I’ve also tried a Linksys SLM2008 8-Port switch and experience NO communication problems on any ports.
I’ve tried a hub and it works 100%
I notice that after trying to ping the network appliance on a non-working port, I can see the device properly listed in the ARP table on both the switch AND laptop. So I am unable to ping the device yet it somehow makes it into the ARP table.
Any help with this issue would be greatly appreciated.
Best regards,
Rob

Hi,
Thanks for explanation that not all ports are the same.
I've just had a similar issue with a Siemens C470IP ip phone. It worked fine with my Dlink 8-port DES3010F switch which I've just replaced with the SRW2016, and also when plugged into my Draytek 2820n ADSL router's LAN ports. I'm a bit disappointed that I happened to plug the device into port 3 and suddenly my monitoring showed that things were not working properly. I checked cables and then remembered that auto-negotiation sometimes can cause problems.
On the SRW2016 if I leave the port with auto-negotiate on I see:
                              Flow
Port   Enable   Link Spd/Dpx Ctrl
g3      ENABLE   UP    10H     Off
Yet inspite this pinging the device does not work properly. That is I get from ping:
64 bytes from 192.168.0.36: icmp_seq=431 ttl=128 time=7.357 ms
Request timeout for icmp_seq 432
64 bytes from 192.168.0.36: icmp_seq=433 ttl=128 time=8.956 ms
Request timeout for icmp_seq 434
64 bytes from 192.168.0.36: icmp_seq=435 ttl=128 time=5.920 ms
Request timeout for icmp_seq 436
Request timeout for icmp_seq 437
Request timeout for icmp_seq 438
Request timeout for icmp_seq 439
Request timeout for icmp_seq 440
64 bytes from 192.168.0.36: icmp_seq=441 ttl=128 time=9.242 ms
Request timeout for icmp_seq 442
Request timeout for icmp_seq 443
Request timeout for icmp_seq 444
Request timeout for icmp_seq 445
Doing the explicit configuration of 10Mb Half duplex as suggested does not help either. In fact it's worse as I get no responses from a ping and it does not make any difference if I enable flow control or not.
So must be the Siemens device? Well plugging into port 16 as suggested makes all the difference:
Auto negotiation works and the link comes up and works fine:
That is:
                Auto          Flow
Port   Enable Neg. Spd/Dpx Ctrl
g13      ENABLE   On   Auto    Off
g14      ENABLE   On   Auto    Off
g15      ENABLE   On   Auto    Off
g16      ENABLE   On   Auto    Off
and
                                Flow
Port   Enable   Link Spd/Dpx Ctrl
g14     ENABLE   DOWN -----   ---
g15     ENABLE   DOWN -----   ---
g16     ENABLE   UP    10H     Off
and ping shows what I expect:
64 bytes from 192.168.0.36: icmp_seq=353 ttl=128 time=5.918 ms
64 bytes from 192.168.0.36: icmp_seq=354 ttl=128 time=6.675 ms

64 bytes from 192.168.0.36: icmp_seq=369 ttl=128 time=8.797 ms
So why is this broken? Is it a firmware issue or a hardware issue? The firmware I'm using is I believe the latest though it looks rather old:
Boot Version:          1.0.1 (Date: 11-Jun-2006, Time: 18:43:59)
Software Version:      1.2.2b (Date: 28-Feb-2008, Time: 16:47:37)
Hardware Version:      00.03.00
If this affects me it's likely to affect others and I really wanted to buy the switch to add to the number of "managed ports" I have. This current behaviour is rather disappointing and I would have hoped that perhaps a firmware upgrade would solve this, or the documentation would be clearer that some devices do not work properly (auto-negotiation seems to be rather a troublesome subject). Is such a fix available?

E1200 - Ports not working and mac filtering problem

If there was a way to give negative stars to this router, I would. As it is, the minimum rating I can give this product is one star, and that's one star too many.
I was upgrading from the WRT54G, which is an ugly thing to look at, but a reliable workhorse nonetheless. I turned that in to a downstream switch in my comms hub.
On the E1200, I flashed the latest firmware, used different Cat5 cables, and different laptops before committing to hating this product.
The first time I reached out to Amazon, the Amazon rep gave me a Cisco number to call. Turns out, that's some shady mortgage refinance hotline. Try it for yourself! 1-800-666-1771.
Now, the rant -
1. Two out of four wired LAN ports don't work: What can be the fix for this?! The activity lights on ports 3 and 4 blink and suggest data transfer is taking place, but the wired laptop simply can't acquire an IP address and access the internet. Same result when I connect my Panasonic Blu-Ray player to ports 3 and 4. None of the Viera Cast features load.
2. MAC filtering unreliable: The wireless routing works somewhat reliably, if and only if, one settles for the most basic security. If I only choose a password and WPA2 protocol, things work fine. If I add another layer of security (in my case, enabling MAC filtering and only PERMITTING gateway to listed MAC IDs), things break down. As soon as I disable MAC filtering, wireless access to authenticated clients is restored.
3. Cisco customer service: The censored world we live in, compels me to criticize politely. TERRIBLE. Cisco website is unintuitive, and frustrating. There's no easy way to register your purchased product. The Cisco "registration" is intentionally misleading and deceptive. For all intents and purposes, it's just an information gathering tool for Cisco. Don't bother registering there, unless you love the idea of storing your personal information on their servers. Their phone-based customer service is apathetic and uninterested. My rep was so distrusting of my intelligence and motor control, that he simply wouldn't believe that I had selected "PERMIT" and not "PREVENT" as the option under MAC filtering. After he asked me the same question for the fourth time, I raised my voice, and he gave up the idea of checking for the fifth time.
However, this review is a tale of two companies. I reached out to Amazon again. This time, I got a rockstar in the shape of Leanne C! She was incredibly helpful, and understanding. What's more, she set up my return without any hassle and this Cisco dud is on its way back. I'm a big fan of Leanne's and my confidence in Amazon is restored.
I'm sure that i received a lemon. I've never had problems with Linksys products. Maybe others' experience is different from mine.

In your case as port numbers 1 and 2 does not work, what you could have done a loop back test. To perform a loop back test you need to take an ethernet cable, connect one end of that cable to internet port and the other end to the non-working port on the router. If you get the led to glow on both internet and the respective ethernet port that indicates that the port is working fine.
It could also be a sychronization issue between the above mentioned lan ports and the lan card of your computer. As a part of trouble shooting you can try to reduce the card speed of your lan card. Following are the steps to reduce the speed of your lan card.
START--> right-click My Network Places and click Properties
right-click on the device manager and click properties
Click on the CONFIGURE button
Select the ADVANCED tab and in the box under the header property select "speed and duplex" and change the value on the right to 10 mbps half duplex. A restart would be recommended after performing these steps.
In the second half you said that after enabling the mac filter option the internet breaks down. Here, do you mean to say that the computer
gets disconnected from the wireless network or it stays connected with a valid IP address but without an internet connection.
Well, it is an unusual issue however you could have reset and reconfigure the router as you got the latest firmware upgraded on it.
Steps to reset the router:
Push the reset button on router for 30 seconds, turn off the router wait for 30 seconds and then power it on. Power light should blink when you perform the reset process.

Recently bought airport Extreme and have connected the device to the modem. WIFI works. However when I connect the LAN port to a switch I do not see the LAN printer and my NAS. Which setting do I miss?

I have installed my Airport Extreme and have conencted it directly to a modem. WIFI works fine. However I do not see my LAN network (printer. NAS,..).
Analysis:
Scen#1: When I connect the LAN port of the Airport Extreme to a switch (as input) and connect the other LAN devices also to the switch, those LAN devices do not have access to the internet. Also connecting the iPAD with WIFI to the Airport Extreme I cannot find my LAN printer and other devices.
Scen#2: When I connect the LAN port of the Airport Extreme to a router X (as input) and connect the router X to the same switch, and the LAN devices to the switch, those LAN devices do have access to the internet. Also connecting the iPAD with WIFI to the router X I can find my LAN printer and other devices in the LAN network.
Question what has impacted the behaviour of the Airport Extreme, not to detect the devices in the LAN network. Why is the use of a switch directly behind the Airport Extreme not working (no internet access for the other devices and Airport Extreme is not the basis station for the LAN network)?

Your scenario #1 is a correct configuration and should work. It seems as though your Extreme is not acting as a router as I believe you intend.
Most likely, you need to reset your modem. Power it down and let it rest for a few moments. Some need longer than others. Then, I recommend you "hard reset" your Extreme (see below) and configure it again, after the modem has been reset. From then on do not change what is connected to your modem without powering it down first.
Once configured, confirm your Extreme's wireless network works as expected and that your iPad and every other wireless device can load web pages. Then, connect the printer directly to one of the Extreme's LAN ports and confirm that it works as well. After that it should work equally well with a switch between it and the Extreme, as should every other wired device connected to the switch. This assumes your switch is an unmanaged device requiring no specific configuration.
Scenario #2: Having a router connected downstream of another is not a normal configuration, so don't pursue that as a solution. It will only distract you from determining the problem. If you want to repurpose Router X as another device do so only after everything else is working to your satisfaction.
To "hard reset" an AirPort Base Station: make sure it's powered up, then press and hold its tiny reset button and keep it depressed for five to ten seconds, long enough for its LED to flash amber rapidly. Release the reset button. Then, the LED will glow amber steadily for about a minute. Then, it will flash amber, slowly, about once every second or two, waiting for you to configure it with AirPort Utility.
