I'm in charge of the IT of a dorm with 200 inhabitants. A lot of people complain about the bad quality of "skype-calls". Audio is delayed and video stucks. The actual speed of our internet connection should be fast enough so I guess it has something to do with the QOS setting. I checked it on our WLC 3750 and right now we use Silver (best effort). Could there be any improvement when I set it to Platinum?
View 15 RepliesI just bought an e2500 to replace my WRT54g, hoping that it would fix my call dropping problem. I had tried installing some friend recommended third party firmware on the WRT54g that he said would fix my problem, and with my infinite technological wisdom and experience ended up bricking it.
My problem is that randomly during skype calls with my family back home, I will lose internet connection. It drops the skype call and then I cannot open a web page or anything for about 60 seconds. My internets dead, then it just starts working normally again by itself. I can have anywhere from 60 seconds of connectivity up to 20 minutes or more while skyping. This all happens over a wired connection. Changing the router didn't change a thing, the problem still happens in exactly the same way. I have good bandwidth and all that stuff.Also, I watch netflix on my Xbox 360 over a wireless connection. Sometimes it will just lose connection in the middle of a show. However, the difference is that I can reconnect almost instantly after an interruption on that device. I have fixed the settings on the two different channels according to one of the other post I found in this community, and have not tried those settings out yet. This doesn't worry me as much as the wired connection issues.
We have a 100Mbps metro-ethernet link connecting to a remote site. This link is terminating in our 3750-x stack switch.We are getting a LOT of output drop on that interface and our remote IP Phone calls keep going off because of that.I've disabled all kind of QoS, but no luck.

How to export Air Quality reports from a 5508? I'm pretty sure I have read that we can not look back in time at the Air Quality report from the WLC, but can from NCS. If NCS was in the picture, can the Air Qaulity Report somehow be exported?

I am facing voice quality issue while traffic flowing through the MPLS over GRE tunnel. Its working fine If I am removing the mls Qos in Cisco 3550 Interface.
[Code]....
I have a client using a VOIP service to a third party provider (RingCentral). They are connected via Cable ISP (6mb) to the Internet and now experiencing performance issues with their VOIP service. They indicated that the call can be heard but that there is jitter and choppines in the call and they have to place a regular landline call. Their provider recommended using QOS to improve. I did not see anything straight forward on the ASDM interface to do this and figure it may require command line to accomplish.
They have Cisco IP 303 and 5252G2 phones which connect through an ASA5505 7.2(4) to their provider for service. Apparently the voip app uses the following ports:
UDP
5060-5090
8000-8200
16384-16482
What would be the best solution to improve performance or perhaps traffic shape / priortize traffic to work. I assume this may be happening if there are heavy downloads or activity happening on the network. The ASA5505 is on 7.2(4). Some coded examples for the above info.
I have a cisco851 and is currently configured this way.
1 .- This well configured?
2 .- the internet encourages me a little as I can improve
3. - how I can improve the performance
I have a wireless router on the ground floor of my home which is wired to my PC on the 3rd floor. The wifi signal is of poor quality on the 3rd floor. I cannot move the router to a different floor since all of my connections are wired through the home into my networking room (on the ground floor where my router is). I wish to add a media receiver to a different room on the 3rd floor that is not wired already for networking. Streaming video files wirelessly to the media receiver from my router will not work because as stated previously the signal quality is poor on the 3rd floor. My mobo on my computer has ASUS wifi GO. Can I enable the wifi go on the mobo of my PC (located on 3rd floor) to connect to the media receiver (also on the 3rd floor) for streaming? The media receiver will also have an internet browser so will I be able to connect to the internet as well if it is networked to my PC and my PC is connected to my router on the ground floor?
I basically want to keep my PC connected to my main router for high DL speeds and also have my PC networked wirelessly to my media receiver using the on board wifi go. If possible I'd also like to be able to access the internet on the media receiver via the PC.
I'm considering using this cam as a live cam pointed across the street to a beach and ocean view. Would it produce a decent video if used for this purpose? I've been looking around for some sample video from this cam but so far no luck. Any sample sites I could log into to see the 930l in action?
View 3 Replies View RelatedHad problems with voice quality on VoIP with 4500 series switches and the qos dbl feature (which gets enabled by the auto qos feature)?? I have had a couple of customer complaining about voice quality and our voice team spent a lot of time investigating; I had ruled out the network infrastructure because it was all QOS enabled. The voip people came up against a blank so I looked at the network once more and disbaled dbl with hope more than anything else. Mysteriously the voice quality issues the customer was having have now disappeared. Not sure whether a coincidence (though I have done this on two customers now) or something to with with dbl. There is nothing on this on cco.

View 1 Replies View RelatedWe have branches all over the country and we take different links like fiber (Ethernet) radio links etc. Now sometimes when we ping from branch WAN ip to its gateway or to the aggregation router (ASR 1000) in this case, we see some drops, but see no problem in actual HTTP or lotus communication.
What i want to know, that now a days, should we rely on ping results to determine link quality ? or should i use tools like iperf to basically see if the link is actually treating tcp and udp packets properly, I have heard this countless times that normally network devices like Cisco routers, even without any QOS, will give low priority to ping packets.
I will be building my own computer here in the next month and am looking to become quite informed about building my own wireless network.Trouble is, I'm a bit out of to with what I need and what is good. I'm also officially tired of renting a modem from Comcast (bastards keep bumping my monthly rate up). So what pieces of equipment do I need to build a simple quality wireless network for my home? I would like the network to support two laptops, one desktop, and an Xbox plugged into a LAN line. Also, I'm thinking of using a Rosewill Wirelss Adapter 3 antenna [URL].

Starter info... I'm running Hardware Rev A4 of the DIR-655 on the 1.33NA firmware. I never upgraded past that firmware because of all the horror stories I'd read about new firmware here. Up until lately it's been fairly stable. The issues I refer to SEEM to coincide with my recent installation of Apple TV hardware on my wireless network, though I can't confirm. It's never been great with this router, so that could be coincidental. On my network I have a hardwired Mac Mini, wireless Macbook Pro, a hardwired D-Link DNS-321 NAS box, Apple TV, Logitech Revue, iPad, iPod Touch, iPhone and occasionally one each of a Samsung and LG Bluray player (only when they're powered up, which is rarely). I'm also using a wireless repeater in the middle of my house because the DIR-655 doesn't yield a very usable signal in my master bedroom, which is on the opposite side of the house as the router.
With all that being said... I have had terrible issues being able to keep a steady connection wirelessly with this router as of late. Streaming Youtube videos will stop after a few seconds, loading websites will just stop responding all together, and I can't even keep a connection to stream music from my Mac Mini to my phone or AppleTV using Home Sharing in iTunes. I'll get a few seconds of a song and it will just drop out completely. It's been extremely annoying and I'm ready to take a hammer to this router, to be honest.
I've checked my logs and there were all kinds of FIN:ACK, PSH:ACK and SYN:ACK TCP packets that are being blocked. I noticed many of them were coming from Apple IP addresses, so I assume that the AppleTV had a lot to do with those. I actually used the Inbound Filter settings to allow requests from a whole block of Apple IP's, which seems to have settled log items from them down a lot. There are still quite a few that seem to be coming from Google IP addresses (I presume the Logitech Revue since it uses the Google TV interface?), but the Google IP's are too random to go allowing a large block.

I have Advanced DNS disabled. All Traffic Shaping and QoS boxes are checked to enable. Comcast is my cable internet provider. I've noticed that my WAN Connection Up Time is often a fairly low number like the connection to the cable modem drops out frequently.
I play an online game, and latency is critical. I usually play at one server, and typically I get around 100ms ping. Today, when I joined the server I noticed my ping is now 40-45ms. My IP has not changed, internet service has not changed, service of server has not changed. It's almost as if the latency *just got better*. I know there are probably a huge number of factors regarding this, but I'm wondering how I could investigate this. Preferably, I'd like to keep my latency at 40ms, but I have no idea how it got there.
View 1 Replies View RelatedMy dad uses 2 modems, somehow they connect the whole house to the internet wireless. We all use laptops and 2 xboxs' but sometimes the connection will dip, not often but sometimes. Do you think this is my wireless adapter in my laptop or because of the use of modems to open up a wireless network?I was thinking about buying a router and just connecting it to the modem to maybe improve the connection. Suggestions? I really do not know the configuration my dad did for this network, the only thing I know is he uses modems not routers which is pretty strange.
View 1 Replies View RelatedBasically we have recently upgraded to a 100M connection but are having issues with the bandwidth we receive. Normally I'd blame the ISP and complain at them till something happens but there are some weird things.Basically one guy consistently receives 50M according to internet speed tests, while the rest of us have never measured above 10M. It should be noted that he is on a Mac and the rest of us are PCs.Having retested repeatedly at different times of day, wired and wireless.My network settings says that my LAN connection is 100M but my internet claims to never even reach a fraction of this. Are there any obvious ways to improve my connectivity?

View 1 Replies View RelatedBought the new EA4500 a couple of days ago and have looked at my wireless connection and see it varies from 72Mbps to 144Mbps. It has jumped up to 270Mbps a few times, but rarely. Shouldn't it be 300Mbps most of the time? My laptop is 4 feet away from the router and the router is on top of a card board box being elevated away from interference. The prior router was a dlink 855 that went whacky after 3 years. I believe I was usually at 270 Mbps with that. What gives? Do I have a faulty router? With this new router, I expected the range to be a lot farther and faster too, but it is not in my family room. 2nd floor router, family room is 1st floor about 50 feet away and I get 1Mbps - 5Mbps. Everything is set to Auto on router and IP6 is disabled on laptop.
