Half Bandwidth Over Wireless

I bought an Asus Wireless Router RT-N66R yesterday, and it has successfully hooked up to everything around my home, except for my personal laptop. I run 14.04 Trusty Tsar on it. The wireless works for about 30 seconds before the computer stops recognizing it, and then I have to reconnect it again by clicking on the network name. Everything else in the house works great with it, and for the 30 or so seconds it stays connected to my laptop, my laptop works great as well. Also, when I am connected to Facebook, it tends to let me continue IMing people, even if I have no connection anywhere else. I can usually google my way to an answer, but I am really stumped on this one, please help!

I have several computers connected to a D-Link DIR605L router, two with ethernet cables and two through wifi. The Windows XP computer can see itself and nobody else. The Ubuntu (trusty) desktop and Ubuntu (lucid) netbook computers see nobody (unable to retrieve file list from server) and the Windows Vista computer only sees itself. Clearly, I have failed to configure something or a set of somethings.
Do I have to have one of the computers always on, acting as some kind of file server or can the router do this job? This is a new router. My old one (whose power supply went phut) connected everybody without arguing about it and we could share files around, even with a mix of OSs.
Since this is a local network only, I have no firewalls enabled, as far as I know ...
All of the network set-up posts I've found rabbit on about how to get your internet connection working through your router, which is not an option for me. I have dial-up working on the XP computer and a mobile wireless USB dongle for internet access on the trusty desktop.
I've installed samba and a few other packages, but so far, none of them have solved my problem. Can someone please tell me where to start and which tutorials to read? If I have to set up a computer as a file server, I guess it will have to be the XP thing, as it's the only one that is always running, but I'd like to avoid that, if possible, as I speak XP worse than I speak Ubuntu.
BTW, D-Link are no help at all, two hours on the 'phone and they were still trying to get me to connect to an ADSL service I don't have ...

I installed Ubuntu 15.04 but with earlier versions this happened too. The problem is, with HTTP or normal downloads like watching youtube the speed is like 20kB/s and with bittorrent I can achieve the full 600kB/s of my network, while in Windows 7 I can download the same files or watch the same videos and have them use the full speed of my network.

Any ideas? what do I have to change so HTTP works fast too? because I think the driver is not the problem since transmission works fine
Thanks

EDIT: And with ethernet cable everything works at full speed

I want to connect a windows workstation to a rh linux network by a 35 meter network cable but it reads 10 Mbps speed and I can't virualize a physical redhat machine in the network
Is the problem with the windows, the cable length or I need to do some configuration in redhat.

Hi,

I have Kali linux and updated it a few days ago and now when I search for networks after going into monitor mode it tells me "no wireless networks found". before the update, monitor mode used to be "mon0" After the update, after entering monitor mode it says "wlan0mon" not sure if this helps. I use Wicd network manager but the origional network manager also cant see any wireless networks, it says "device not managed".

Thanks

First time Linux Mint user and fist time poster to this forum. Need to install a Linux distro on my family member's HP Mini 1000, an older netbook with minimal hardware (1 GB memory stick, Intel Atom N270 processor, 80 GB ATA HDD, and it runs XP SP3. . I advised her to uninstall XP and buy Windows 7, but she doesn't want to spend the $93. So ...

I have been testing different Linux distros from flash drive on my HP Probook 4530S laptop. Have tried Ubuntu 14x and now Mint, which I prefer. Ubuntu wouldn't boot to desktop on the netbook after choosing "Use without installing." Mint runs OK on it, but I can't configure the wireless connection. I suspect that either the network hardware isn't compatible or I am missing something when trying to manually configure the settings. I read some info from the Mint web site about this issue, but not sure about whether the Mini's wireless card is compatible: Broadcom 802.11b/g WLAN. Does updating Windows drivers help with this?

TIA,

Don

Question: How do I get this laptop to recognize this wireless chip. I know from prior research and experience this chip is optimal for this laptop (used it on winxp)

i have an hp pavilion dv7 laptop and i installed openmandrivalx 14.1 x64 on it and cannot configure the wireless intel centrino wireless n-2230 adapter. Have downloaded the iwlwifi drivers but cannot install because the system cannot resolve the $MIRRORLIST problem.
This occurs on all mandriva based linux systems i hahe tried mageia with the same result. Mageia cannot even recognise the centrino adapter.
Ubuntu based linux systems install on the fly.
What good is an operating system in the modern era that you cannot connect to the internet seamlessly?

I am attempting to install debian to a desktop and It is not configuring my wireless adapter. I am including the error messages as follows:

"missing firm ware file htc-9271.fw"
"Network is probably not using dhcp protocol, network may be slow or hardare not working properly"

I attempted to go to /etc/network/interfaces as root however it says I do not have permission. I then tried adding a new user then going to visudo to add permissions but am unable to insert anything using the (i) command. So at this point I am at a loss.

Any help is greatly appreciated and thank you for your time.

OK this is kinda long, so I will shorten it as much as I can, as to not be long-winded.

My current network at home:
1 - CentOS 7 desktop (server)
1 - Ubuntu 14.04 desktop
1 - Fedora 21 laptop
2 - Windows 7 desktops
some other various windows boxes also that don't get used regularly, but are on the network.

My 2 Linux desktops (which I use as servers, but they really aren't) have shared folders on them, which I share to the network via Samba (CIFS). I use Samba because Linux is smarter than Windows and Windows won't read NFS, so I share them as Samba so all devices can see them.

Generally speaking, if I share the folders on each box as 0777, I have no issues. But lately I have been wanting to implement some better security, so I wanted to SETGID and chown the shared folders from the local machine to a specific group, then change the folders to 2774.

My problem is that I keep getting permissions errors when trying to connect from the other Linux machines, and sometimes the Windows machines also. My main question is: do I CHMOD 2774 the local mount-point before mounting it? Or so I CHMOD 2774 the shared folder on the other server, then mount it locally to a folder whose permissions are different? Or do I CHMOD both of them the same?

basically the uis and gid ownerships change on a local folder when I mount a shared drive to that folder, so when I try to write or sometimes read that local folder, I get permissions errors.

I can provide any additional info needed.
