[Connectivity] wired desktop ruining wireless for other devices?Hello. This might or might not be the correct place for this, so if not please redirect me. My problem is a reoccurring one. My desktop computer has a wired connection with the router and has zero problems whatsoever with connectivity. However, while gaming or streaming videos on the desktop, the wireless connections between the router and the PS3 and laptops becomes very bad if not disconnected altogether. We've had this router replaced 3 times so far and this problem keeps happening. The technician that inspected the last router said it was a faulty one, but we are still having the same problem with the new router we received. Are we just unlucky that we keep getting faulty routers? Or is my desktop doing something to interfere with the routers performance? Please help! This is very ANNOYING! |

Re: [Connectivity] wired desktop ruining wireless for other deviDoes sound like the router can't handle all the connections. But you say a technician came out. I'm assuming that you have a combo device that is your modem AND your router together? If this is true, I would HIGHLY recommend you to get a stand alone wireless router. There are several on the store shelf of BB or target or walmart, or you can get even better (and more expensive) units online. Then you can either get a stand alone modem from the store also, or call in and rent/buy one from the isp.
There's usually little that you can do to troubleshoot on a combo unit and they are generally just not as good as their separated counterparts. |

Thank you for the quick reply! You are correct it is a combo modem/router. When I mentioned all of the devices that we use, I did not mean they were all connected at the same time. If my desktop is the only one being used (streaming or games) on the router, turning on a playstation 3 to stream netflix or play games like Battlefield 3 doesn't work because it acts like there is little to no connectivity (and this is when only my desktop and the ps3 are turned on). When we first started using suddenlink as our isp, we could easily stream Netflix on my desktop and a ps3 at the same time, but now we can't. I apologize if this seems very unorganized, but thank you for your help! |

ya, that is just odd. To answer a question in your original post, no, your desktop isn't doing anything to interfere with the wireless performance. Even if you have some malware/virus on your computer that floods the router with traffic (you should run some scans BTW) that would not effect the signal strength you aren't getting.
On second thought, are you saying that the wireless signal is weak (i.e. 1 bar vs 5 bars or similar)? Or is the actual problem that you have no internet speed when both are on (signal is actually fine, but speeds to the internet are slow)? There is a big difference in what could be wrong based on this. |

Signal strength on the ps3 is strong, fyi. |

It is hard to answer because a ps3 doesn't show connection strength in bar form(that im aware of). However, the ps3 will actually connect to my online account so that I can access the network and whatnot, but after that streaming and gaming becomes seemingly impossible because of connection issues. In shorter terms, i guess you could say I am able to connect but not do anything. (The laptops will show excellent/very good strength. I have not done much with the laptop situation, im mainly aware of the desktop/ps3 issue). |

Could you run a couple speedtest and post them up here, along with what tier you are paying for from suddenlink.
If you are also able to post up your modem signal stats, that would be helpful. |

I ran a test on www.speedtest.net: ping showed 41ms, Download speed was 15.97Mbps and upload was 1.59Mbps.
Another test was ran on www.bandwidthplace.com: Ping was 52ms, Download speed was 13.2 Mbps and upload was 1.54 Mbps.
If I remember right I am paying for 10Mbps speed... I'll double check to make sure.
Haven't checked modem signal stats yet, but I will post them here when I can. |

One issue that I ran into while tooling around with the modem this last summer that cause a TON of issues for both myself and my room-mates is to ENSURE ""NAPT"" Mode is set to Enabled. When disabled, it tends to go with whatever connection is plugged in first, for example - modem resets, desktop is hardwired --> Desktop connects, wireless devices cannot see modem/router. Modem resets, desktop not plugged in ---> Wireless devices see and connect to modem, plugging in desktop will NOT work until you plug in the desktop and reset the modem. |

Without knowing what combo unit you are referring to, or that abaum has, that NAPT mode sounds more or less like the main on/off switch for NAT, without which you can't share a single IP w/out custom scripting all the ports and calls.
Just another reason to urge against combo units
Abaum, those speeds and ping time look fine for your package. You most likely have been upgraded from the 10 meg to the 15 meg package also. |

ps3 internet connection test | arris router |
We are using an Arris touchstone data gateway dg950 . Signal strength on a laptop was 5/5 bars. Ill attach some pictures for extra reference. |

You could just be saturating the link in upload or download. Upload saturation is very easily done with backup software like Carbonite, and especially Crashplan. Most consumer routers do not have QoS, so it is basically first come first served (IE FIFO: First in first out). Your desktop being wired has the most available, least latent connection and can easily overwhelm and saturate the link. Think 100Mbps or even 1000Mbps straight to the router with almost nil latency. Everything else wireless gets much higher latency and SHARED bandwidth at about 56-64Mbps even on Wireless N. And there are NO collisions on the wired link, but the wireless link, yep, many collisions which cause higher latency.
On my setup if Crashplan is running and backing up at full upload speed (2Mbps), my other devices can see a massive slowdown even on download, because remember to download you first have to upload a request and them possibly periodic awk packets.
My recommendation s a better wireless router, or even better, a wireless ap behind a really good wired router preferably one with QoS (Quality of Service). |

Not even sure if many residential router QoS actually works. I've never seen it kick in unless I manually add the rules on all of mine.
But yes, maxed upload = choked download. Usually try to leave 25% upload free at all times so I can atleast open a website unless I'm asleep or something |

You can buy a Cisco 871 for $100 on ebay now and it has QoS, and SDM (web setup) actually works if you don't know CLI. |

Update: we exchanged the router with a new one(same model) the other day and has been working fine so far. Thank you both for your time and effort! |
