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'm looking for a solution to guarantee a particular LAN segment a particular amount of internet bandwidth.  As an example, if the ISP connection is 100Mbps, then I want allow a segment of the LAN and all of its connected clients to have access of up to 80Mbps and any of the other LAN segments the remaining 20Mbps.  The reason for this is separate organization's cost sharing the price of just one incoming cable broadband ISP.  The current setup is a standard cable modem which then feeds to a SOHO router (primarily used for internal DHCP) and then to a mix of managed (layer2/3 capable) switches to several buildings on campus.  I'm open to adding a capability or replacing any of the current devices that could allow for this type of bandwidth control.

I am new to learning computers, but I needto learn as much as I can and one of the areas that's been most difficult has been networks. I have an HP DeskTop computer and a Lenovo ThinkPad, both of which I use and also two Android phones. All of these things live with me in my small room. The network is set up via wireless adapter from my desktop and the entire building is seriviced by a broadband internet connection. This is kind of a hotel with some guests like myself staying for a prolonged period of time, so I often see a lot of people online and sometimes on my network. I want to make my own safe network with VPN and Firewalls and DNS and proxy... as much as I can do to stay invisable to prying eyes.

I have several schools we run an after school program with some are hard wired the others have Hotspots with VOIP phones. Anyhow the end user is using tablets or laptops. I need to setup the Hotspot and router but was looking for any ideas on spreading the signal? I was also considering some sort of Antennas?

 I'm unable to run wires, everything goes in our office and then from there. I need a stronger signal that can go 40-60 feet. I thought about using the hotspot and then using powerline to where the router will go? If that makes any sense. Hook the Hotspot to router, that will need a wire to get the router into the other room.

I have disabled the wireless on the hotspots so I can use my equipment. I have 2 schools I need to set this up at. I'm not sure what to buy or get yet? I'm going for a powerful router but to get from point A to B and then out to tablets. The kids could have 2-3 rooms to use.

Any ideas or anyone with experience that can suggest. I'll get Netgear 3200 unless someone has a better option. I wanted to get Ubiquiti's but I cant run a POE setup on the power adapters....

Any suggestions are greatly appreciated. I need to order equiptment soon... Thank You All...

I told a friend who needs to complete a point to point hardware VPN he needed to get a static IP address at both ends.  One end is his home, and so he calls AT&T uverse to have this done.

 They come out and make adjustments to the router which is a Pace.

Sometime after they leave he tells me he can't get his roku to work, and after calling AT&T they tell him he needs to assign it one of his new public IPs.  They did give his PC a static IP of 76.254.xxx.xxx.  Oddly, when he goes out to the internet to check (ipchicken.com) it's showing his public IP as: 107.200.x.xxx

I was under the assumption they would give him a single public static IP and everything internal would have remained 192.168.1.x

He's called them multiple times and they just keep telling him all of his devices need their own IP and he's responsible for assigning them.  They said static IPs are generally for corporate clients and they wont support a home with static IPs.

Anyone have any experience with AT&T and doing this residential?  Is there anything he can do at the router to have one public static IP and have internal devices get IP's via DHCP?

We have two isps (Virgin and BT) and both hubs have been tested independently and work as advertised.

However, the point of having two isps is that, in the event of one going down, we still have a service.

Hence they are both connected to a Netgear ProSafe Bonding Router. (which, when it's working properly also bonds the services and allows us to approximately double our broadband speed in certain use cases)

My problem is that the router recognises the Virgin Hub, no problem. But does not recognise the BT Hub and this the admin screen is telling me that WAN 2 (the BT hub) is down, when it isn't.

I thought I'd cracked it when I realised that the default ip address of the BT hub was 192.168.1.254 which was already occupied by a Novell Server. So I changed the hub address to .200. Forced the router to refresh its search for hubs.  Nada.

Any ideas?

Having a very strange issue whereby a few webpages do not display correctly on all computers in the office (including a mobile phone  - not on the company domain).
Two examples are speedtest and westin (see below)

speedtest.net page

As such I am doubting the issue is related to any specific computer. Have spoken with the ISP (BT) and they say if they come and visit they will charge if it is not a BT related broadband issue. I am guessing the issue must be either on the router or somehow network related. I have tried local stuff like flushing the DNS, changing DNS to  8.8.8.8 etc but running out of ideas, apart from perhaps resetting the router. Apparently all was working fine up until a couple of days ago on this network. Any help/ideas would be appreciated.

We are a serviced office and have freely just passed broadband between all the tenants.
Since one of the tenants are taking a lot of the bandwidth we now need to apply limits to the pipe.
I’ve checked with out switch and we can only limit upload.
Please can somebody suggest the best way to do this? We can get new hardware if required. But not sure if this is usually achieved via switch or router and how it passes through for 30 separate tenants.
Thanks in advanced.

I have a customer who is experiencing slow online service with Comcast. I have done the basic cleaning eliminating junk files, malware, etc without success. Rebooted the router, changed internet channels, etc. with now success. Since they are connected wirelessly I ran a speed test with Speakeasy. The test defaulted to the Miami NOC where the download speed was ridiculous at 15mbs however when I switched to a different NOC she was getting the speed that she was paying for which was 60-80 mbs and higher. I did this with a different speed test provider as well which showed the same disparity. The only one that showed a fast download time was Comcast's own speed test which of course I expected because in 10 years I have never seen a slow speed using Comcast's tests.
I hooked her up directly to the router with Ethernet and while the speeds were obviously better I received the same differences from various NOCS. Miami low, Atlanta, New York and California high.
My question is this. Does Comcast or for that matter any provider determine which NOC a router goes to by default or is it configurable somehow within the browser?
Or better yet, what am I missing here?
Any help on the subject will help me before I contact Comcast support for her which I'm reluctant to do until I get more information. I'm sure that they will run their test and say everything is OK and it isn't.  Thank you very much for any help anyone can provide.
Kindest regards,

So i have a Standard home broadband Netgear router (DGND3700v2) it connects  to ADSL using a phone line.

can I use a RJ11 TO RJ45 converter and then plug that phone line straight into the outside ethernet port of an ASA5506 and then configure the port to use PPPoe with the credentials from my ISP? would that work?

Thanks

Do cable broadband "splitters" work ?

Problem: one cable going into "TV Box" but if I remove this and use a "splitter". Does this mean I connect it to a cable modem?

No matter what router I use, I only get 30 - 50% of the internet speed through it.

If I connect a laptop directly to the Comcast modem, which is in "Bridge mode" so that the connected device gets a public IP address via DHCP, I get about 100mbps.  If I connect a router BETWEEN the modem and the laptop, the speed falls to 30-50.  There is NO OTHER device connected to the router or the modem.  I have confirmed this problem using a SonicWall TZ400, a Cisco RV180, an ASUS RT-N12, and a UTT ER518.  The issue remains for each of those routers.  I also used the same patch cables for each measurement.  Wireless is not involved.  

Why does this happen and how do I change it?

Dear all,

I would like to seek for all experts for help.
My company has a fortigate 40C firewall, and recently it kept giving me problems, which WAN1 was intermitent down. And after several minutes, it auto connect back. I got checked in the log files, nothing that i can find from there. Is it due to heavy usage of internet that caused the WAN link was down?

May i know how can i troubleshoot for such kind of issue? Kindly please assist.

Thanks,

I recently moved a small Call Center from one location to another. They contacted me late in the game to help them get a new call center setup with very little time. This left me with Comcast as the only ISP to choose from that could install services within their timetable. We decided to go with their new Gigabit package, which includes their new Gb modem. The client also chose to go with Jive for their PBX needs and subsequently ordered 20 Yealink T40P IP phones. Let the issues begin...

Comcast's modem would partially default to factory settings once a week. When I say partial, I mean things such as factory internal Gateway IP and Subnet revert back; passwords are set to default, yet the SSID's are still what we created. Comcast claims that they can ping the modem but when I test connectivity inside the modem to the internet I get 0/4 packets received. This test was run by the modem internal troubleshooting software. The Uptime clock inside the modem says 17,500+ days, which is not possible since we have reset the modem within the last 24 hours and we have only had the service for three weeks. We have factory reset the modem, replaced it with a new one, and we are still having the Yealink phones not obtain an IP address, or they have an IP address but say "No Service", even after they have previously worked. Phones continue to drop off of the network in that manner, and PC's that are using pass-through are losing connectivity as well. No matter how many factory resets on …

my boss has an ...@btinternet.com email account on his iPhone. When  he's connected to talktalk broadband at his home, the account shows error 'port 993 timed out' when synchronising. If the phone is connected to another network or using 3G/4G, it works fine.

The error began a few days ago.

Steps taken;
-turned device off/on
-removed/re-added mail account
-tried toggling SSL on/off
-Spoken to ISP who were unable to help

I'm assuming this is simply an ISP fault but any help would be appreciated.

Thanks

I have a network of about 30 users with a 100x100 fiber connection with Spectrum.  I am using a Sonicwall firewall.  I did a speedtest and saw 96 down and on 6 up so I called Spectrum and they told me we were over utilized and it was extreme.  My question is; how can I figure out what machine is using my bandwidth and narrow down my issue?

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?
