Troubleshooting several internet issues?

Wait, What


Alright. For the past three weeks or so, my entire family has been having multiple internet issues, and we can't get to the bottom of it. Here's how my network is set up: The router and modem are upstairs, and my parent's computers are connected to it. Another set of two desktops are a floor below it, using WiFi to connect. Our ISP is Charter Communications, and we are paying for 30mbps at the moment. The problem we are having is that when one computer downstairs is being used, the other one has low internet speeds. This is proven in gaming and by using http://www.speedtest.net. The two computers upstairs are not affected.

During gaming, if my brother were to open up a video, I would immediately have my ping go up to 600+, and vice versa. When he is gaming, my download rates are around 5mbps download, and 3mbps upload. Usually when his computer is not in use my computer gets 18-25mbps. The router we have is a NETGEAR WNR3500L and our modem is a Motorola Surboard that is pretty old.

My question is, with the information given, what should we do? Should we purchase a more powerful WiFi router/modem, or go talk to Charter about our internet speeds? Thanks ahead of time.



Answer
Disconnect the wireless router and connect a laptop or PC directly to the modem via Ethernet to make sure that you have exclusive use of your Internet connection.

Reboot the PC or laptop so the modem can assign it a IP address. You should have Internet access now.

Go here http://speedtest.net and test your Internet connection speed.

This is your Internet speed. No wireless router, modem or connection type can make it any faster.

If you are going to have multiple users or simultaneous devices such s ROKU boxes to do HD streaming such as Netflix, then you'll want a minimum of 10 Mbps or faster.

Your Internet bandwidth is shared among all of the users of your LAN. So any bandwidth others are using will be deducted from the total WAN (Internet) bandwidth that is available to you.

In simple terms, the more users you have the more speed will be required. Streaming video, such as Netflix and Hulu require a lot of bandwidth. Here are the minimum recommendations from Netflix. https://support.netflix.com/en/node/306

For example, If you pay for a 3 Mbps Internet connection, you will get 3 Mbps.

No router or Ethernet connection will change your 3 Mbps Internet speed. This connection bandwidth is shared by your entire LAN via your router.

If you have a 3 Mbps Internet plan and one user is utilizing 2.5 Mbps of the bandwidth to stream a Netflix movie that only leaves 0.5 Mbps for all of the rest of the users on the LAN.

Fast wireless routers and connections are designed to stream large files on your LAN quickly. The high speed routers permit fast transfer of files between devices connected to your LAN, however WAN speed is still limited by your ISP. The only way to Improve your Internet speed is to upgrade your plan or switch to a faster ISP.

That being said,

If you are using a wireless connection, I would try temporarily plugging your PC or game console directly into the router via a Ethernet cable.

If your game still lags or video buffers with a direct connection, then the best router /modem in the world won't help, you'll need a better Internet connection.

However if the lag goes away then your problem is with the wireless connection between your router and your game console.

Wireless connections are not good for systems used for online gaming. Wireless signals are affected by many factors including distance, wall density, electrical interference, directional antenna range, etc.

By nature, interference in wireless systems causes problems with smooth, consistent speeds. Your latency (ping) may be 30 ms and wireless interference could cause it to spike to 200 ms or more.

You should try to centrally locate your wireless router or gateway up high and away from dense walls and electrical and 2.4 GHz wireless interference such as microwave ovens, cordless phones, baby monitors, etc.

For serious gaming or video streaming your best bet is a direct Ethernet connection. Ethernet is unaffected by wireless interference and will give you a rock solid, stable network connection.

If it is not feasible to run Ethernet cable the next best option would be a set of powerline network adapters http://isp1.us/reviews/netgear-xavb2101-powerline-adapter/

You plug one in by your router and one in the room where you need access and connect them to the devices with standard Ethernet patch cables. The network signals are transmitted over your existing home electrical wiring which will not be affected by wireless interference. There is still overhead in the connection but it is much more stable than WiFi.

Good Luck...

HP computers and reliability?

So I've been in the market for a new computer. I currently have a Toshiba Satellite A305 that has been my baby for the past 5 years but it's time for an upgrade. It has an old Centrino 2 processor, 4GB RAM, 320Gb HD and an ATI Mobility Radeon Graphics card. It does what I want, but slowly. It was fast when it was new, but the more expansions I add to my games the slower it gets, and Windows Vista has been nothing but trouble from the start. It uses too many resources and has way too many driver compatibility issues. And now I'm having weird black-out problems with the monitor.

This is my #1 prospect for the price: http://www.ebay.com/itm/HP-Black-dv6t-7000-15-6-i7-3612qm-2-1GHZ-6GB-640GB-DVD-RW-Cam-Laptop-Win-8-upg-/221171230259?pt=Laptops_Nov05&hash=item337ed52633

I really wanted an ASUS, based on what I've heard from others. I have heard mixed reviews on HP, but I think I may have to settle for HP due to the budget. What do you think? Would this computer work for my needs? I game (mostly Sims 3), use Photoshop CS 3 & 5, surf the internet, stream music, and watch movies. I frequently multitask. I also have a 15lb cat that likes to sit/walk on my computer. I also want this to be a long-term investment. I need something that will hold up and be reliable. Is an HP a decent prospect for that?
@Doru: A laptop is a computer. It is a specific type, yes, but it is still a computer. Did you even look at the link? This is not an entry level under $500. It DOES have a 3rd generation i7, a NVIDIA dedicated graphics card, and a 6GB HD. The specs are way better than what I have now and what I have now can handle the games I play. I'm just looking for an upgrade (that doesn't have monitor blackouts and the terror of Vista). I cannot afford more than $700. I'm trying to stick close to $600, so yes, for the specs I want, and in that price range, I'm looking at refurbished. I have bought refurbished before and have never had a problem. The computer I have now is a refurb and it lasted me a good 5 years. It could probably go longer if I forced it to. As long as there is a decent return policy I have no qualms about giving it a shot. I really just want to know if HPs are built to last or if they're too much of a hit-or-miss.



Answer
My sister has the same laptop that you want to buy and it works quite well with her I think. She uses it to do homework, stream videos, and plays games such as League of Legends with it. She's only had the computer for a year so I don't know how it runs long term. I'd say that the laptop would be a good choice for you, although you'll have to anticipate the battery life going down.
