I have a "Linksys AC1200" router which supports 802.11ac and I have a Dell Latitude (with Win7) with a "Dell Wireless 1504 802.11b/g/n (2.4GHz)" network adapter. Since 802.11ac is backwards compatible with 802.11n, as I understand it, it seems like I should be getting wireless-n speeds. But I'm not.  When I right click on the network connection and select Properties I see that my speed is 11.0 Mbps. It seems to me that my network speed should be a lot faster. Any idea as to why it isn't?

I have a Linksys E4200 router and a laptop with an Intel Centrino Wireless-N 135 adapter. If I place my laptop right next to the router, the link speed is about 20 Mbps. Is that normal or is there any way I can increase it?  (P.S. Sorry if this question sounds stupid...)

I have a number of servers in my room, and I'd like to have a high-speed wired LAN within the room between my servers and my desktop and laptop. My internet access is provided by a cable modem connected to a wireless router, and I'd like it to stay that way (my Internet connection setup is at the other end of the house). Are there any routers (wireless or wired) out there that could provide a wired LAN in my room, but use a wireless connection as the Internet source? (the router in my room would be connected to my house's hotspot and use that as the Internet connection for the LAN in my room).

Using a wired connection, I get a 38 Mbit/s download speed. When I switch to wireless one (Linksys WRT54GL router with Tomato firmware), the speed drops to 23 Mbit/s even if the distance between the router and the computer is 2 or 3 meters.  Is that a maximum effective bit rate I can expect from an 802.11g connection? Are there any settings I can tweak to to increase the download speed?

How can I set up my WiFi to be used as wireless access point on Ubuntu Server?  I have a local Ubuntu Server, it has a wireless card in it (802.11a/b/g/n) and I really want to set it up as an 802.11n access point since my normal access point does not support N.  It needs to work as a switch as well so I can connect and get DHPC through.  Edit: I don't see Network Manager as a good solution since it depends on a lot of X11 packages, and i don't want that on a server.

I've just decided to jump into the world of Ubuntu, so far I encountered no problems until I tried to connect to my wireless network. I'm running Ubuntu on my laptop, Acer Aspire 5333-2880, which has an Acer Nplify 802.11b/g/n wireless card.  After browsing for an answer, I think the problem is a missing driver. input:   lspci | grep Network   output:     02:00.0 Network controller; Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)   I found a couple of answers that might be right, but I have problems with both of them.    It requires me to load the site in my laptop, but I can't do it without internet and I have no idea how to save this into a USB.  But I have no idea how to really run or use this, and I wouldn't like to screw it up.    Any advice or other possible solutions will be greatly appreciated!   EDIT.  Thanks a lot for your input Marko and Jorge. I am sure the problem was with one of the drivers, but I was too distracted, or tired yesterday to realize I didn't restart my computer after installing. As soon as I got turned on my computer again, it was working. Annoyingly, I am not sure what the problem was exactly nor what exactly fixed it.  But still, thanks a lot Marko for the intel on how to build packages, I am sure it will be very useful later on!

I pay for a 50Mbit/s connection. When I connect modem from ISP directly to my PC, the speed is OK. But since we share this connection, I have to use router.  It's nothing archaic, TP-LINK TL-R402M, but when I connect modem to this router, and then PC to router the speed drops to 10Mbit/s (even when noone else is connected). I have absolutely no idea what causes this, I tried replacing a cable, even borrowed a router to try it with it, but it still acts the same.

I have read similar questions in the past (i.e.  and ), however they don't address my question adequately.  I am attempting to understand if I can use 2 separate wireless cards on my Desktop PC to connect to the same wireless router at the same time, specifically as so:   WiFi Adapter 1 using 5Ghz 802.11ac to Router WiFi Adapter 2 using 2.4Ghz 802.11n to Router (same router)   Currently I have them set to 2 different SSIDs, although that certainly can be changed if needed.  To be clear, I want to use both networks to boost speeds, that's the intent here.

I've been having an ongoing problem with my home WiFi network. As stated in the title, my 2.4GHz network is slow but 5GHz is perfectly fine. I've checked with a WiFi analyzer and there aren't too many other 2.4 networks around, and I'm using the recommended channel. The connection is generally spotty, sometimes seeming fine and other times dropping to a crawl.  In an attempt to combat the problem I bought a new router, and split off some of the traffic to my old router. So my network setup is:   main router: Netgear Nighthawk X10 R9000, on 192.168.0.1 child router (downstairs): TP Link Archer C3200, on 192.168.1.1   The child router is hardwired in to the main router on a cat5 cable, and broadcasts its own 2.4 and 5GHz networks, and both routers have the same problem. The main router does have other electronics nearby (AV receiver, home wireless phone, cable box, modem), but the child router has nothing nearby.  I've switched from 2.4 to 5GHz and run speed tests while 2.4 is going slow, and 5GHz is always fine.  For the most part this isn't a major problem, I'm just using 5GHz whenever I can. But I have a home security system, and those cameras only run on 2.4GHz. So whenever I connect to one of them, it complains that the network is slow, and it's difficult for me to review saved clips. Also, maybe one day in the future I'll decide to save money and switch to a cheaper internet plan, losing 5GHz entirely.  So my questions are:   how can this be? how can I troubleshoot it / fix it? could it be my ISP? (optimum online) is there a way to monitor all 2.4GHz traffic and see if some massive amount of data is passing through it all the time, indicating maybe a virus on a local machine or something?

I've got a new laptop with a wireless card which runs Windows 7.  At work, I put the laptop in a docking station that gives the laptop a hardwired internet connection and functions pretty much like desktop PC.  But there isn't any WiFi signal in my building that I can use, so various portable devices that depend on WiFi  for an internet connection (iPod Touch and Kindle) are hobbled.  I'd like to provide them internet connections without spending more money, if possible.  So what I'd like to do is install some sort of virtual WiFi router on my PC.  Is that possible?    N. B. There is a related (but not identical ) that has an  that I think will work for me.  It won't hurt my feelings if this question is closed with a link to the other question, but I think they require different answers.

What's a simplistic recipe to connect my PC to my WLAN through my laptop?  I have one wireless network, one desktop that (for practical reasons) has no connection to the WLAN, and one laptop with wireless and an ethernet port.  I would like to run a cable from my desktop to my laptop, connect my laptop to my WLAN and forward the network to my desktop.   Is there a solution?

In our home network, with continuous network IO happening latencies get ridiculous. It's fine with light loads but quickly becomes unusable if I'm, say, rsyncing a large number of small files, --other transfers essentially stop. Pings get through just barely.  Simple topology -- a broadband modem / WIFI router in a single box, with some wireless and some wired clients.   I've tried setting ifconfig wlan0/eth0 txqueuelen 1 on all clients, this seems to help a bit but not by much.  Tips welcome: how should I go about diagnosing and eliminating latency problems? Are there more configuration settings I can set on clients, or maybe a better WIFI routers could help?

Just installed Ubuntu on new HP desktop "pavillion"all in one. Dual boot set up. I get the message no wifi adapter found when attempting to get online. What to do? Oh I do not know how to copy and paste my terminal info so it actually looks like it does on the terminal. (A little help with that would stop annoying people that are reading my questions.)  When I enter sudo lshw -C network I get:  *-network                  description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 logical name: enp1s0 version: 15 serial: c8:d9:d2:7b:00:b3 size: 1Gbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl8168h-2_0.0.2 02/26/15 ip=10.0.0.223 latency=0 link=yes multicast=yes port=MII speed=1Gbit/s resources: irq:49 ioport:f000(size=256) memory:fea04000-fea04fff memory:fea00000-fea03fff *-network UNCLAIMED description: Network controller product: Realtek Semiconductor Co., Ltd. vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 version: 00 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: ioport:e000(size=256) memory:fe900000-fe90ffff   So I followed the already answered question advice of making sure I had the correct kernel which is currently 4.15 and I have the most updated rtl8822befw.bin firmware installed and I still am getting the no wifi adapter prompt.

I have just moved back to Ubuntu from Windows 7 and a few months ago, I bought a NETGEAR WNA3100 wireless adapter because my old adapter had broken. I plugged in my adapter and it doesn't seem to work, I also used the windows 7 drivers for it and tried them on the program "Windows Wireless Drivers" and they don't seem to recognize the device. However I have heard you need XP drivers but I can't seem to find them on the internet nor find them on the CD.  Could anyone help me get my wireless adapter to work? Any help is greatly appreciate.   P.S I do have internet connection though I have to tether my phone to my computer and then connect my phone to my router.

I have a router with ADSL Pentagram Cerberus 6331-42. Is it normal to have transfer speeds between two computers of max 1MB/s (not 1 Mbit)? How can I set my router up to make it faster at transferring data in my local WiFi network?  I have a PC and a laptop. Both are running Windows 7. I don't use a firewall. I've set the network area up correctly; I can see other computers.  Is it possible to make the router faster by changing its values? I don't use secure encryption such as WPA or WEP; only MAC filtering.  My values in Interface Setup > Wireless are:       Here are my thoughts after few years I've published this topic:    use 5Ghz bandwidth if possible  use range extender if Your router is too far  try wifi analyzer app for mobile phone to check what channel is the less used

I have a problem with my network adapter after upgrading from 13.04 to 13.10. The adapter works for literally several seconds after I establish the connection but then it looks as if it got clogged somehow.  This is what I see amongst my devices:  ~$ lspci | grep -i wireless 02:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01) ~$ uname -a Linux bubek 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:12:00 UTC 2013 i686 i686 i686 GNU/Linux ~$ lsmod | grep 80211 lib80211_crypt_tkip    17387  0  lib80211               14040  2 wl,lib80211_crypt_tkip cfg80211              401436  1 wl   Now, how does is behave. Let's assume I connect to my wireless network and straight after I get connected I ping the default gw:  ~$ ping 10.1.0.1 PING 10.1.0.1 (10.1.0.1) 56(84) bytes of data. 64 bytes from 10.1.0.1: icmp_seq=1 ttl=64 time=226 ms 64 bytes from 10.1.0.1: icmp_seq=4 ttl=64 time=222 ms 64 bytes from 10.1.0.1: icmp_seq=7 ttl=64 time=260 ms 64 bytes from 10.1.0.1: icmp_seq=11 ttl=64 time=265 ms 64 bytes from 10.1.0.1: icmp_seq=16 ttl=64 time=117 ms From 10.1.0.16 icmp_seq=45 Destination Host Unreachable From 10.1.0.16 icmp_seq=46 Destination Host Unreachable   What has happened over here? Is there any possibility I can get it working? The only way I could write that post was that I used my phone and USB tethering :)  Thanks for any tips in advance!

I haven't noticed any pattern and I'm sure the Wi-Fi works perfectly because I have no problems with the same computer using Windows 10. The Wi-Fi doesn't turn off though, it simply disconnects from the network and reconnects after about a couple of minutes.  I ran this and got:  lspci -knn | grep Net -A2 03:00.0 Network controller [0280]: Qualcomm Atheros AR9462 Wireless Network Adapter [168c:0034] (rev 01) Subsystem: AzureWave AR9462 Wireless Network Adapter [1a3b:2234] Kernel driver in use: ath9k Kernel modules: ath9k   Also running dmesg  Among the many messages the last one is:  [ 3818.806656] wlp3s0: Limiting TX power to 5 dBm as advertised by 00:23:eb:39:28:21   Any idea why this is happening?
