Home Network :: Prevent Multicast From Flooding Wifi?
Apr 12, 2011
My IPTV connection works fine so far but as soon as I start watching TV I can't use my WiFi connection anymore. My router is an "Alice Modem 1121" (SIEMENS S1621-Z220-A) with 4 LAN ports and a WiFi interface (4th LAN port provides the IPTV). It is directly connected by wire to my PC's ethernet card for the IPTV and the internet is provided via the WiFi. When I activate the LAN connection the WiFi and internet connction stays up and requests can be sent but nothing returns anymore. Another device (iPod) has no problems with accessing the internet while IPTV is in use. I also have a Netgear WNR1000v3 router which I tried to use as AP instead but it's exactly the same problem. Unlucky the Netgear router is not supported to use dd-wrt firmware yet (I've found a step by step guide to prevent multicast floods with dd-wrt/ebtables). But maybe the Alice Modem can handle this problem on its own. I read some stuff about VLANs and splitting them but I have no clue how that would look like.
The "nas_0_1_34" is for the IPTV.

I have a 2x Cisco 3750G switches (Stacked) that are part of an IP Video Surveillance System .All network is set to 1 VLAN (VLAN 1 default).The Cisco SWs ( Core ) are configured with IGMP Querier + Snooping .Connected to the Cisco SWs are 4 Fiber Rings(Loops) for redundancy . RSTP and IGMP Snooping are enabled on all the network SWs .Network Architecture Figure :
When all Fiber Rings (Loops ) are connected , the Cisco and Ring SWs spanning-tree tables show the blocked and forwarding ports properly .I am able to connect all my IP Cams + Encoders to the Ring SWs and connect my Servers + WorkStations to the Cisco SWs to record and view the multicast ip streams .All streams from Rings 1 ,3 and 4 are getting normally to the Servers + WorkStations through multicast ( IGMP Snooping are filled correctly on the Cisco and non-Cisco SWs ) . All multicast streams are joined normally except for Ring 2 .The Multicast streams passing through Ring 2 will operate normally for around 2 hours then after that the Fiber SWs begin to flood their multicast traffic causing the cams on the same switch to drop off the network .
I checked the Configuration of all the SWs on Ring 2 but all are are the same .
What is weird is that I have to set all the streams to unicast to stop the flooding just on Ring 2 (All other rings are not affected ) then after some time if I enabled a video multicast stream on one of the SWs of the Ring it will be streamed properly to the Servers + WorkStations ( All IGMP tables along the way will be filled properly ) then again after 2 hours or so , the flooding will start again suddenly and all IGMP table entries for the SW on Ring2 will be empty . No problem occurs on the other Rings which have more multicast streams .

We have a couple of switches with a L3 Vlan 238 interface which runs PIM SM and OSPF, and HSRP. We have connected to this same segment telemetry processors which have raw socket interfaces configured - which means it picks up all IP packets which hit the interface and forwards them along.So we dont want the processor to recevie any of the 224.x.x.x switch housekeeping traffic? is there anyway to prevent that ?

Is blocking echo request to prevent ping sweep the same as having a firewall in stealth mode? And how could someone ping sweep from outside if you had a firewall at all?

Currently in my office have a TPlink wireless router (WR1043N), and Dlink 615 router.Below is my office's network organization.Internet-->TPLinkRouter(192.168.2.0)-->DlinkRouter(192.168.0.0)We want to host a demo website but we are afraid our network being attacked. So we wish to implement a DMZ network to hide our internal network from outside. My question is can i setup a dmz network with the above capabilities by using home routers?

I have a Canon ScanFront 220 network scanner that seems to have a problem with our network. It's plugged into a Cisco 3560. The network is operational, just chatty.
A wireshark session for just a few seconds looks like this: (192.168.81.42 is the scanner)

I can't find anything on the scanner that would cause this.

Here's the layout: Cable modem in the basement. Several devices in which I'd prefer a wired connection in the basement. Upstairs on the 1st and 2nd floor of the house are many devices in which wifi is fine or preferred.Here's the problem: As you might guess, wifi is weak upstairs and certainly on the patio and 2nd floor. I have an access point upstairs that I've experimented with but it is flaky.

I have high speed wifi at home and the wifi is WPA-PSK protected. My neighbour will be coming to my home to work with me and I will be keying my wifi password into his Windows XP laptop for him to access my wifi.
This is one time access only, after that he is not allowed to access my wifi. To prevent him from accessing my wifi, I will have to delete the password that I keyed into his laptop.
Where do I find this wifi password in the Windows XP? What folder and what filename?

My Wifi network has a wpa2 password that is a random string of characters and numbers and yet last month a rogue IP Address kept popping up on my DNS list. It has to be coming from my neighbor who's bedroom is about 15 feet away from my router. So unless someone is sitting out on my front lawn to do this then it must be him.I've been looking for software that will notify me when a connection my router is attempted and kudos if it also asks my permission first would be great.There are wifi packet sniffers out there like Cain&Abel, Airsnort, that sort of thing but I am not quite savvy enough nor do I want to turn this into a complicated hobby but just need a basic warningin case something gets past my passwords again

I'm having an issue with my network, where we're are experiencing random and brief network outages. They happen a couple times a day and last 5-10 seconds. when I check my two backbone switches (4506 : Supervisor: WS-X4516-10GE ,IOS : cat4500-ipbase-mz.122-31.SGA8.bin), STP remains normal and no topology change occurs.

Neighbor agreed to let me use his WiFi connection only if it requires no changes or disruptions on his side. His signal is broadcast with a wireless router. I can currently see his signal broadcast on my laptop, but it's very weak.I have a omnidirectional antennae already mounted outside my house with a clear sight of view. It has a cable attached to it that terminates with a N connector inside my building.I need to connect to his signal (there are several being broadcast in the area) and then forward it to my router. My router will then provide connectivity to my home network.What hardware do I need between the outdoor omnidirectional antennae (that terminates with a N connector) and the wireless router inside my building?

have a home network setup that works completely fine everywhere in the house except one room. That room happens to be my son's room that has his Xbox 360 in it. He wants to play online but I cant get a signal back in there and if I do it is extremely weak. I have a linksys E2500 router connected to my cable modem that is wired ot one computer and then my 2 laptops connect to the wireless from that router. The Playstation 3 that is about 15 feet away works fine as well. All our ipods and iPhones work well too. It is only his bedroom where we run into trouble with any of these devices. I actually just upgraded to the E2500 about 2 months ago, so I have a Motorola WR850G sitting around. Can I use this closer to his room to lengthen my signal or how can I proceed to get him a better signal

it shows that it is Online getting an Excellent Connection thru my Home Network... I go Online using Firefox with it at home.. stays up for a few minutes .. can get onto the internet...then loses the ability to stay connected.... it still states it's Connected though ... kind of baffling... like something is timing out then blocking it...I tried shutting down my AVG Anti-Virus.. also shut down Windows Firewall... it still continues to lose the Connection while stating it's connected getting a good signal... both of these are configured correctly as far as I can seeI've re-installed my Wireless driver thru the Acer Recovery Management included on the Netbook.. still no good..

At my workplace, we have high speed internet (dsl). We don't have Wifi or a full time tech guy at the moment. I was thinking about proposing it since I generally handle most of the technical items at my job, but wanted to verify a few things first. First of all.. on a work network.. is it any more difficult than your average home network to set up a wifi router? Anything special I should know before attempting to set one up?

I recently got my laptop fixed after it being out of commission for about a year (it turns out there was just too much dust collecting in it) and when I got home and tried to connect to my wifi network, I didn't have internet access. I received a message that said I had sucessfully connected to my network but it was only a local connection - no internet. It also shows up as "Unidentified Network." This is peculiar to me because my boyfriend's laptop is able to connect to the internet wirelessly just fine, and I am currently using the wifi on my iPhone. I ran the ipconfig and several ping tests in cmd and used a wifi inspector.

im using microsoft network monitor to monitor all traffic in and out (public) and mirrored ports for local traffic, except wireless traffic as its connecting to the router. I want to use a wifi NIC on the server to broadcast, so wireless clients can connect via the server and obtain DNS and DHCP etc from there, therefor, monitoring all traffic.

setting up a single home network in my apartment that will be able to connect to and use 2 separate wifi internet connections to provide stability and reliable bandwidth for a home network.
Situation: I have recently moved into an apartment complex that has 2 separate wifi connections that are available to the residents free of charge. (yes i am authorized to use both) I do have the option of paying for and having my own personal DSL line installed but I would much rather use the free wifi and not have the monthly bill.
The Problem: My apartment is located far enough away from each of the routers (One wifi at each end of the building and I am in the middle) that my signal strength is poor most of the time and sometimes heavy traffic on one wifi requires that I disconnect and connect to the other. Wifi A is farther and has very low signal and low or no connectivity. Wifi B has good signal most of the time but gets very slow during peek usage times of the day.
I understand that I need one or more high gain antennas in order to receive adequate signals from either Wifi connection.
Between me and my son we have 2 laptop PCs, 1 Desktop PC, 1 network printer, 1 Xbox, 1 HDTV and my smartphone. I don't want to try to equip each device with its own high gain antenna and try to figure out which device should be connected to which Wifi depending on available signal and bandwidth. Rite now I do not have a Home network set up at all and we are only using 1 laptop and the Xbox and each is directly connected via wifi (usually to Wifi B).
If I could connect to either Wifi A or B with decent bandwidth and reliability and then be able to network or connect all my devices via wireless or wired to my own router/extender etc. I would be happy. However.. Given that I must share bandwidth with the other residents and at times one Wifi has heavy use while the other does not. I have been trying to research how to connect to both wifi signals for load balancing, reliability and hopefully greater bandwidth.

My wife is moving into an apartment complex for school and she has a Brother HL-2270DW printer. Since she only has a laptop and moves around the apartment, I would like to use the wireless on the printer. Unfortunately, the internet for the building is just through wireless APs. I have the printer installed on the network, but my concern is that anyone can just search for network printers and install it. While printing on it won't be useful for them, it could be a good way to waste her paper/toner. Is there a way to prevent users from installing it without being able to change the router settings? I did not see any option in the web configuration.

I'm planning to replace my flaky minipcie wifi and I need advice about the antenna.My laptop has two sets of antenna, one for 3G WWAN and the other is for normal wifiAccording to the labels, both is "Main" and "Aux". The card that I'm planning to get is an Intel 5300 which has 3 antennas.Since the normal wifi only has two antennas, can I use the 3G WWAN as a third antenna? If yes, should I plug in the "Main" or the "Aux"? If no, Should I buy those additonal antennas in Ebay for the 3rd one?

Currently I am hosting a 7 day mountain retreat, for about 90+ people. Clearly they are dependent on the internet teet as am I I am trying very hard to provide internet to our friends, but I just can't seem to figure it out I have a Mobile Broadband Router (MBBR) which limits connected devices to 6, so I figured that if connect a home router with wifi (WIFI) that allows 253 connections problem solved right? So I put a short LAN cable from the LAN port on the MBBR to the WAN port on the WIFI and presto! The WIFI gets a IP address, but does not allow other users of the WIFI to get internet. I've even killed all security on the WIFI and put the WIFIs IP in the DMZ on the MBBR. I noticed the DNS was the same as the gateway on the WIFI, so I changed that to the DNS on the MBBR still nothing.
PS Yes I have a connection on the MBBR I am on it now.Connecting the LAN cable from the MBBRs LAN to the WIFIs LAN extends the range, and grants internet to the WIFI users... but uses the MBBRs DHCP to give IP addresses, which limits to 6.I guess the goal here is bypass the limitation of the MBBR by using the WIFIs DHCP to issue IPs?
