The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Broadband includes several high-speed transmission technologies such as digital subscriber line (DSL), cable, fiber optics, wireless (for which there is a separate topic), satellite and broadband over powerlines (BPL).

I had this question after viewing Setup webcam to take photo every minute.

I don't even know if this is possible but I would like to automate a WiFi cam to email me a photo from my rooftop at regular intervals - say every half hour. I only want stills and want them emailed to a digital WiFi photo frame. The idea is to enjoy the view that I don't have but avoiding killing the broadband with continuous video streaming. I have heard about yawcam which seems to have this functionality, but appears to be for Windows only.
Thanks

Hi

I am running a Asus router with Asus WRT-Merlin as the firmware.

Until recently I always used Google's DNS servers of 8.8.8.8 and 8.8.4.4 rather than my ISP's as I thought for international traffic there was a slight speed improvement and that has worked fine for years.

However I recently moved to a new property and as per usual was using the Google DNS servers and everything is fine for a few days until my broadband starts getting really slow and if I go and change the DNS servers to automatically use my ISP's the broadband speed goes back to normal again for a few days until the same thing happens and then I again switch back to Google and keep repeating this process for months now.

I am fairly technical when it comes to networks but I can't figure out why this would be the case that I have to change the DNS servers three times a week to keep my broadband speed consistent. I know that DNS servers could be experiencing a slow down so it makes sense to switch DNS servers for a while but to have to repeat this on such as regular basis seems to apply there is a something else up with either my broadband connection as a whole or my router. It's not such a hardship to make the change but would rather not have to do it if I can avoid it and I am more curious than annoyed with the situation.

If someone has any ideas about what is going on or ever heard of something similar before?

Doubt it helps or makes a difference but previously I have always lived in a …

Hi.

My home broadband is, as I understand it, fibre to the local junction box (less than a mile away) and then very old copper to my house. When I first signed up a couple of years ago, I was consistently getting around 40Mbs down and 10Mbps up.

During this period ( the "golden age") , the line would occasionally "fail" but, as I'll explain,  with minimal impact to me. I say "fail" because Ping and TraceRT worked, but more importantly, using a VPN (Witopia), I could happily "punch through" the problem and reliably get my full 40Mbps. The ISP engineer would eventually arrive out, test the line, agree that it could support 40Mbs, agree that there was no problem in my house, go away, do "someting" and my connection would go back to providing 40mbs without the VPN. Happy days, indeed,

Sadly, back in May. at 23:36 one night, my line went down and when it came back *three* minutes later, my max speed had gone from 40Mbps to 22Mps (with upload going from 10Mbps to 3.3Mbps). Aargh! Unfortunately, I had neither the time nor the energy to get into an extended row with my ISP and "settled" for 30Mbps down, 10Mbps up (which I verified independently).

And now my latest situation - as of a week or so ago, performance has collapsed. Some times my line supports 30Mbs/10Mbps, but for extended periods, I'm getting some data, but usually not enough to even load a web page. Unless, of course, I use my VPN. But not all of its setups work - I get a perfect connection using …

I'm trying to understand the assignment of IP addresses when the broadband modem (for example Draytek 130, which in the UK only operates in bridge mode) is separate from the router.

My understanding is that a bridge operates at level 2; it passes packets from one side to the other, converting between the different technologies at levels 2 and 1 (in this case between Ethernet on the inside and some-telephone-stuff (which I don't really understand) on the outside.  Therefore it has no IP address of its own, IP being a level 3 thing.

So if the ISP assigns an IP address to the subscriber of (say) 81.152.10.12, then that's what the WAN port of the router is, and the modem is transparent at the IP level.

But the manual for the Draytek modem says that if you connect a PC to the ethernet port it can get a DHCP address in 192.168.2.x.  That's the same ethernet port that bridges 81.152.10.12 to the WAN port of the router.  How can this be? Does the modem run a web server on some 192.168.2.x address at the same time as bridging the external IP address to the router?

Like this?  Have I got that right?

Hi there,

I have been on ADSL in my apartment for 5 years and only JUST found out that there is actually a fibre to the building connection which then branches out via VDSL to the copper of all the apartments, I am looking to switch over immediately. However I am hesitant to disconnect my current ADSL as I rely heavily on the internet and downtime would impact me badly.
I spoke to the company that provides the fibre and VDSL and they said that It is possibly I could have two connections running  (VDSL and ADSL) and that in my apartment complex they are completely seperate in terms of wiring. However this confuses me a bit as VDSL would be running through the same copper wiring that my ADSL is currently connected to right? (my modem would be plugging into the exact same place etc).

Would it be wise to disconnect the ADSL before I sign up with VDSL with this other provider? they would be sending out a technician to configure whatever needs to be done in the MDF room? and then set up the router etc. is that just meaning he would switch the inactive copper line (if there is one) onto the VDSL connection and then the VDSL modem would then be configured to detect that and run off of that? or do they not know what they are talking about.

Also is it possible to have the internet on VDSL and keep the phone number and line active with my old provider as I cant be bothered to switch that over aswell or is that not possible? I need to get this done ASAP so any help would be …

Hi All,

We got Linksys LGS552p switch, and TZ400 Firewall.
behind a "AT&T Modem"  , but we have external IP for the TZ 400.

I need to setup VLANS, 90 for workstations, 20 or servers and 50 for voice.

am I missing any hardware to route between the VLANS?
where should I start with first?


thanks

I have two locations with almost duplicate setups.  
Location 1:  On a network run by a PDC.  The ISP is a cable company.   The one office in this location has 3 computers all connected to the network via a Netgear 5 port switch.  But also connected to this switch is a DSL connection via a dsl modem line to a preset location..  When the users need to connect to this dsl line they just click on the shortcut created on their desktop that directs them to the preset IP address.   All other communication for everything else goes through the regular PDC/cable network.  Using DHCP and automatically sees PDC as DNS provider.  Works great.

Location 2;  On a network but run just by a router, not a PDC,  through the local Cable company.  Two computers connected via an identical 5 port Netgear switch as in the location 1.  They have the the exact same dsl line via the same dsl modem connecting to the same IP address as in location 1.  The problem is that you can only connect to one or the other in location 2.  If you want to connect to the dsl location via the dsl modem, you have to disconnect the cable from the router from cable company at the Netgear switch.   Or if you want to  use cable you need to disconnect dsl modem from switch.  Also running DHCP and DNS being provided by either the DSL or cable depending on which you are using.  

What would cause one to work and the almost identical one won't?

Hello,
we have a TZ-210 wireless that need to change a couple of things on.  

We are connected to a comcast business gateway device.  It has wireless and we use that as an outside wireless,  It is not setup to access the internal network.  When we setup a laptop of phone we use that for VPN testing and remote connectivity.  I have 2 issues.

1. I cannot connect to the management interface on the modem, it is the default 10.1.10.1.  It keeps getting dropped in the firewall.  What rukes do I add to tallow this?
2. We cannot send email from our mobile devices when connected to the Comcast wireless.  I would expect it to be a rule as well, but I'm not sure what to add to make this work.

We want to keep the comcast wireless off the internal network. But we need to access the management interface, plus some of the users need to be able to send via exchange when using devices or phones and sending exchange email.

Thanks.

Over the past few weeks my laptop has appeared to be non-responsive. Running speedtests shows the download speed is fine, but the upload will start strong, then the test just seems to hang. I've tried multiple browsers, uninstalled the antivirus, turned off the firewall and Bitdefender but nothing seems to help. Thinking it was the router, I ran a speedtest tethered to my phone, but similar results. Another laptop worked fine with the router as well.

I see no issues in event log, and I tried to update the wireless drivers but it was up to date. I'm not sure what my next step should be.

Thanks for any help.

I have 5 IP's assigned by AT&T to me on my On Demand Fiber circuit, but I only have 1 public address to the WAN. How do configure my 3 TZ300 to each use one of the assigned IP address and each to be a DHCP server?

I have an internet semi leased line purchased it for business purpose (250 Mbps).

I've recently purchased a new wireless router (Dlink-DIR-842) and placed it in office for internet access. Initially when i setup the wireless router, i was getting speed of 35Mb UP 32Mb Down when over the wireless. All of a sudden, the wireless has gotten very very slow and i see only 3 Mb up/1Mb down sometimes not even 2Mbps. But when i connect thru LAN, it give me damn good speed upto 75up/80down. As a workaround, I've tried changing the wireless channel from Auto to 6 and then to 11 but none of them has changed anything.

Confirmed that there is no issues with the line as it give almost near to what ISP has promised if i connect directly. Any suggestion for the wireless settings?


I presume the issue is with Router itself. Also, Dlink-DIR-842 doesn't have much settings options where i could look for some sort of troubleshooting.

Screenshots of the settings are attached for your reference.

Hello,

I am switching some of our broadband connection from ADSL to NBN and with that need to put a new modem into our existing infrastructure

We are going to use a Cisco 887VAW which is compatible with the NBN network with the correct firmware for these

Can someone please take a look at my Bridge Config as its a little different to my normal ADSL ones i use on the old routers as now has the vdsl interface

I think this is right but please let me know

I have put a Management IP on vlan11 FA3 as well so i can access the until via telnet

Has anyone worked with DSLAMs before?  If so, what manufacturer?  I currently am testing a DSLAM but not having much luck when not in bridging mode.  We must have our clients isolated from the modems and DSLAMs and can't use these devices just to pass through data traffic.

VIDEO: THE CONCERTO CLOUD FOR HEALTHCARE

Modern healthcare requires a modern cloud. View this brief video to understand how the Concerto Cloud for Healthcare can help your organization.

This is our current small office's setup:


Ciena 3930 fiber modem (provided by at&t)
ethernet cable connected to modem (port #2)
cable drop through ceiling --> office IT room
1 port switch converting cable into RJ45 IN

Connecting my laptop directly with an ethernet cable into this port, using the static IP provided by my ISP, I get my full bandwidth during speed tests (100mbps down/up)

Connect a router into the port (Apple Airport Extreme) --> connect via wifi to router
speed test shows ~15mbps down/ ~50mbps up

Connect via ethernet cable into router
speed test shows ~15mbps down / ~50mbps up

Thinking the router was having issues, I brought my Asus AC1900 from home, factory reset it, and set it up with the static IP, etc. and am getting the same results as from the Apple router.

As soon as the router is removed, I can get a full 100/100 connection directly to my laptop

Are there any compatibility issues with "enterprise grade" fiber modems and "consumer grade" routers that could be causing this?

If you would like any other information that might help, please let me know and I will update ASAP.

Thank you

Hi Everyone,

I'm having what I believe to be a DNS issue.
We recently moved our office and have a new ISP; Comcast. We have a new external static IP address and that seems to be working. We are able to send and receive Email without issue. Comcast has updated our rDNS so that's all set too.
The problem is accessing certain web sites. For example, Google comes up fine but when I try to access support.hp.com, the site never loads.
I have a ReadyNet WiFi router (provided by Comcast) between our internal network and the Comcast modem which is in pass through mode. The ReadyNet router is acting as our Gateway and for all intents and purposes is working as it should.
When I use nslookup from my workstation for www.google.com, I get 2 responses. The first is from our internal DNS server. Good. But the second, Non-authoritative answer is:
Name: www.google.com.<our internal domain name>  i.e: www.google.com.company.com
Address: <this is our old external static IP address> ?????

I'm at a loss as to how it can be returning our old external static IP. Where is it getting that from?
I have 3 servers. One is the DC the other is our Exchange server and finally, a secondary DC of sorts.
Both the DC's are running DNS. One DC is running Windows Server 2008 R2 Std. Ed. and the other is running Windows 2003 Std. Ed.
The funny thing is I can surf any website from the servers without issue. Of course, these all have static IP's, DNS IP's, etc.
However, if I do an nslookup …

Hi There,

The internet speed at work has become very slow for our users,
We have 100mbp speeds however, its taking more than 3 seconds to load a page up.
We have changed the DNS names server from Google DNS to Open DNS on our firewall, However, this
Has had little positive effect.

I have a small business network where I want to limit the bandwidth to each user, preferably being able to configure that in groups or via SSID where I could limit groups of users.  The current setup uses 2 separate unlinked BT Infinity FTTC lines with BT hub5 router where the users are split across both lines however on either line it only takes a few people to stream and the service clogs up. I'd like to be able to limit each person so if someone streams video it doesn't affect other users.  It would be nice to to be able to block sites such as youtube if I need to go down that route.  The network is not server based, merely laptops connected directly to the router with IP's assigned via DHCP.

Over the past year I have had intermittent but repeated problems with dropped internet connections. Oddly, it usually happens only on weekends when activity on my home network I believe is low. My internet provider tells me that it is a bandwidth issue. Specifically, they are telling me I am exceeding the upload capacity of my connection and that this is causing the connection to drop.   They tell me that this is commonly due to a cloud backup or similar condition.  I am not running a backup at that time and cannot figure out what is causing this issue.
- Is there an "easy" way to troubleshoot this?
- Is there a way to use my Sonicwall firewall to place limits on upload and prevent the connection from dropping?
