Ubuntu Networking :: Asus Eee PC 1005HA Drops 50% Of Incoming Packets Over Wifi?

Oct 30, 2010

Pinging out from my netbook (over wifi, to any host) gets ~0% packet loss. Pinging into it (from any host) gets about 50% packet loss.

The router is a Dlink-DIR615 (rev d, running DD-WRT v24-sp2) but all other hosts on it ping eachother fine. I've tried changing routing, disabling IPv6, using older kernels and using wicd, all with no luck. The wireless connections is at 100% most of the time. This could be a new problem with Maverick, but I may not have noticed it before. I believe this is causing web browsing to be really slow and causing SSH timeouts.

I haven't tried madwifi drivers or nsidwrapper yet.

Edit: just booted into Windows and it has the same problem. Could it be a hardware issue? Also tried with a static IP, with no change.

Strangely, a normal ping gets 50% packet loss, but ping -A gets < 1% loss.

Edit 2: no packet loss at all on eth0.

Code:
# uname -a
Linux hulbert-laptop 2.6.35-23-generic #36-Ubuntu SMP Tue Oct 26 17:03:18 UTC 2010 i686 GNU/Linux
Code:

Networking :: Mark All Incoming Packets On Connection?

Apr 6, 2010

I have a router which makes two ppp connections. PPP0 is my default route and is an uncapped ADSL. PPP1 is a Local Only (South Africa) account which has DNS resolving to its IP. PPP1 allows certain connections in. I want all packets coming in on PPP1 to be marked so that after they have been routed through our local servers they can go back out over PPP1. Both connections use dynamically assigned ip addresses. I want to use PPP0 to make a connection to one of our stores, but when our stores connect to us they will be using PPP1. All packets from these incoming connections will need to be routed back over PPP1.

CentOS 5 Networking :: NIC Drops Packets / But Reports No Errors

Jul 24, 2009

I've got an odd one, running the CentOS 5.3 kernel, I'm experiencing lost packets on one of the two NICs when tested with ping. In this particular case, it's the internal NIC that causes the problem, pings from the CentOS machine to the public network over the external NIC never loses packets.(internet)<-->CentOS<--> (LAN) <--> desktop

- CentOS can ping the internet with no packet loss
- CentOS loses packets when pinging the desktop(s)
- Desktops lose packets when pinging the CentOS box
- Taking the LAN switch out of the equation still results in lost packets
- When the LAN NIC on the CentOS box "acts up", all desktops start losing packets

I've swapped out the NIC a few times for different makes/models, and I'm still getting lost packets to/from the internal network. So, I'm thinking that there's something squirrely going on higher up in the network stack. But evidently, not enough to log anything to the console or into the log files.At the moment, I'm leaning towards it being an issue with the nForce 750a SLI chipset. But it's odd that it only affects the LAN card and not the WAN card. I've even swapped the positions of the two NICs, and the problem persists on the LAN card.The other possibility is that iptables is eating packets silently, but in a random fashion.

I have a system running 11.04 and it is dropping packets on the hardwired ethernet interface to other systems on the LAN, only in the inbound direction. It drops packets every 5 seconds. I verified this with iperf. Outbound packets pass with no problems. The network card in this system is a Broadcom Corporation NetXtreme BCM5752

Ubuntu Installation :: Asus Eeepc 1005HA Can't Boot From Usb

Nov 27, 2010

I can't get my Asus Eeepc 1005HA to boot from usb so as to re install Ubuntu. I did it right once - obviously - and now have a malfunctioning dual boot partition. My memory is of having to hit a function key repeatedly once I'd changed the BIOS and restarted the computer. Asus forums all repeatedly give me the same advice - F2 for BIOS, F10 to save settings then it should boot up, but --- nothing --- works.

So. Any additional or creative advice? The computer doesn't have a CD drive. My thumb drive is a Delkin 4gig... are there thumb drives known to work for this operation?

OpenSUSE Network :: No Internet Connection On Asus Eeepc 1005HA?

Aug 23, 2009

Within a dual boot option two os are now available on the asus eeepc 1005ha,

(1) the windows xp system and in addition (2) the linux 11.1 version of opensuse.

After and also during the installation process of the linux 11.1 os, an error message had occured:

No network found!

I tried to fix it by changing some settings (network manager on/off), but no

improvement could be achieved. Some people argue to wait for a kernel

update higher than *.27.*

Somebody knows something how to fix the network (eth0) internet connection?

Ubuntu :: No Incoming Packets With Ekiga?

Nov 2, 2010

I am using a NanoStation 2 in Router mode.The NS is connected wirelessly to my neighbor's router and a switch is connect via ethernet to the NS for LAN use.

The past few days I'm trying to use a VoIP client software to connect to my VoIP account.I use Ekiga Softphone to do so, which requires UDP ports 3478-3479 and 5000-5100 to be open.

So I have opened these ports both on my neighbor's router and on the NS.The problem that I'm encountering is that although I manage to register to the VoIP service, when I answer an incoming call the caller is able to hear me, but I'm not able to hear the caller.So I used wireshark and figured that there is no incoming traffic on my end.

I have used many linux VoIP clients with PCs connecting straight forward to an ADSL router and worked perfectly.

Ubuntu Networking :: Wifi Connection Drops On Laptop?

May 1, 2010

I'm having a really strange problem with my wifi connection on my laptop. The ethernet connection works fine and so does the wifi connection - as long as I sit within one meters range from my router! As soon as I take the laptop further away the connection drops. The router is still being found by network-manager and the signal is just below 100%, but when I try to establish a connection it fails.

I'm sitting here on a fresh Ubuntu 10.04 install, and I had exactly the same problem with 9.10. That time I went through a lot of different procedures, and in some strange way the problem was solved. I haven't been that lucky this time though, I've tried reinstalling network-manager, using ndiswrapper, installing the wireless backports package, tried all kinds of drivers.. nothing works.

There shouldn't be any problem with the connection itself; I've had a perfect connection downstairs but now I can't even connect if I stand two metres from the router! Has anyone experienced anything like this and managed to fix it? My wireless card is Atheros AR2413. This is an example from daemon.log

Ubuntu Networking :: Wifi Not Reliable And Picture Drops?

Sep 26, 2010

I have a dual booth system (ubuntu (64 bit) and windows 7 (also 64))... In both systems I have trouble with my wifi:Sometimes it works for a few hours without trouble and then I stops working every 10/15 seconds after reconnecting. In windows it keeps on reconnecting, but in ubuntu sometimes also the wifi logo/picture disappears from my panel, so I can't start wifi again or see it's status.

Ubuntu Networking :: Wifi Speed Drops Periodically And Will Not Increase Without Reconnecting?

Jan 25, 2011

after maybe half an hour, the wireless download rate drops to about 110ks (and runs happily at up to 20x this until then). At that point, it will never pick back up above that rate unless i disconnect and reconnect. Once the problem occurs once, its like to reoccur about every 5 to 10 minutes until the machine has rebooted.

Ubuntu Networking :: Get The Asus N13 WiFi To Be Controlled By The Network Manager App

Mar 11, 2011

I have eventually (a week's work) got my Ubuntu 10.04 to recognise my Asus N13 WiFi dongle (had to compile the source from Ralink with the "y" against the two things it tells you to if you want network manager to work (source that came with dongle wouldn't compile) and then set up rules (for some reason the driver - rt2870sta - wouldn't recognise the dongle until the rule about the vendor and product ID was in place; and the drivers that come with Ubuntu wouldn't recognise it even with the rule in place)).

Big thank you to chilli555 for all of the posts that got me this far.I would like to use the Network Manager app that comes with Ubuntu, to control the dongle. At the moment it will aknowledge when the driver has been loaded (have to do a modprobe), but does not "see" any of the many WiFi routers around my house, so I can't click on one to select one.

My only guess on this is that, to get the dongle to work I copied the config file that is part of the driver source files into /etc/Wireless/RT2870, and this is getting in the way. However, I have tried removing it and the network manager still doesn't work. Or is it because the network manager needs the dongle to be called "wlan0" and it's called "ra0"? If so, can you aliase this?

Ubuntu Networking :: Wifi Only Temporarily Connects On Asus EEE 1000HE?

Jul 4, 2011

I've got an Asus EEE 1000HE, and it's worked fine for a long time with the EEEBUNTU distro (a distro based on Jaunty (i think) with a custom kernel). Unfortunately, Eeebuntu is no longer maintained, so I recently did a clean install of Ubuntu 10.04.2. I am now unable to get my wifi to work reliably.

The wifi tries to connect for a while, then pops up the "Wireless Network Authentication Required" window. If I hit "connect" it will try again for a while, then pop up the window. Etc. Note I know that my connection information is OK. I haven't mistyped the password (see below). Also note that the wifi antenna is turned on. For example, iwlist scan is able to find my network.

There is a weird twist though: The netbook is always able to connect through an ethernet cable on eth0 just fine. If I boot the netbook with the ethernet cable plugged in, the wifi instantly connects as well! I can then unplug the ethernet cable (eth0 goes away), but I am still able to use the wifi connection for about 5 minutes before it disconnects, and goes back to trying and failing to connect.

This behavior is 100% replicable--the wifi always works fine (for about 5 minutes) if it boots with the ethernet cable plugged in. Very rarely, the wifi will also connect on boot without the ethernet cable, but that is not replicable.

Other EEE netbooks seem to have issues with multiple wireless drivers, like in this thread. Perhaps something similar is happening here? My card seems to be using rt2860sta as a driver. I tried blacklisting it, to see if another driver was trying to load instead, but that just negated my wifi altogether. (It's unblacklisted again)

My router is a very reliable Linksys WRT54GL with factory firmware which has never been flaky.

I'm at my wit's end. This netbook will be useless without wifi.

Below is the suggested information for a first post:

Here's lspci (note there is nothing listed as "Wireless Brand" to grep out):

Code:
lspci
00:00.0 Host bridge: Intel Corporation Mobile 945GME Express Memory Controller Hub (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)

Ubuntu Networking :: 10.10 / Asus EeePC 1001P - Can't Connect To Internet - Only Wifi

Feb 5, 2011

Just got a secondhand Asus EeePC 100P netbook, fresh install of Ubuntu 10.10, and while I can connect to my wireless network and access the router through the browser, I can't connect to the internet. Pinging any other sites, either by domain name or IP, doesn't work. I've tried various things suggested in similar threads (putting in the DNS server info manually, disabling ipv6, restarting about a gazillion times), but nothing's worked so far. (My other computer, a Mac, can connect just fine.)

Attempted to install ndiswrapper, failed miserably, and I'm not sure if that's just for situations where the wifi itself doesn't work?

I'd be very grateful for any suggestions.

Here's what's under Connection Information at the moment:Interface: 802.11 WiFi (wlan0)

Hardware Address: 1C:4B6:85:13:F4
Driver: ath9k
Speed: 1 Mb/s

Security :: Iptables State Module - Configuration Error / Not Enable Incoming Packets From Connections Initiated From Inside?

Mar 30, 2011

I have a server that I can only access via SSH (it's located far away) and I would like to secure it by blocking all ports except the ones that I need (which are HTTP and SSH). I still want to be able to make outgoing connections to enable software updates and other things.This is my iptables -L -n :

Code:
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:1:21
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:23:79
DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpts:81:65535
code....

In my opinion, this should block all incoming packets except the ones on port 80 and 22, but allow responses to outgoing connections. But a wget http://google.com does not work, it can't establish the connection.

Maybe this is not the best style for iptables rules, but I want to be absolutely sure to not accidently lock myself out from SSH, so I chose not to configure a "block-everything rule".

Does this configuration not enable incoming packets from connections initiated from inside?

Ubuntu Networking :: Asus EEEpc 1000H Wifi In WPA-PSK Mode No Longer Works

May 5, 2010

I have an Asus EEEpc 1000H netbook with both Ubuntu and WinXp. I just updated from Ubuntu 9.1 to 10.04 and I can no longer connect to my home WiFi!

I have a Netgear router and the network is WPA-PSK password protected. All other devices can perfectly connect. The netbook can under WinXp and could with Ubuntu 9.1. Now, with the 10.04, it keeps asking for the password but never connects. Obviously I triple checked the password and there's no chance of a mistype error.

Networking :: Can't Get Wireless Working In Slitaz (Asus Aspire ZG5, Atheros Wifi)?

Sep 17, 2010

So I decided to wipe out Windows and try Slitaz. It's an awesome well featured distro for it's size. One huge problem tho: I can't get wireless to work for the life of me. I actually went as far as to manually load the ath5k module but It just refuses to recognize my wireless router, much less any nearby routers. It simply doesn't see anything when it scans for wireless networks. I have no problem with that in Puppy Lucid. But I'd really like to use Slitaz, just for it's small size and quick bootup. Can anyone PLEASE help me with that?

PS: It happened here before that I had to plea and beg for any response, so PLEASE(!!) don't let me hang like that this time.

Networking :: Firewall - Allow Packets Coming From Internet After Authenticating And To By Pass Packets Generated From Internal LAN?

Feb 8, 2010

i have a linux server runnig oracle applications. i need to access this server from putty using ssh through internet. i did by registering my static ip with the dnydns.org and i am able to connect to the server. but now there is no security to authenticate any user as any one knowing the password can login to it.

i thought of configuring the firewall of linux server but the client ip`s are not static and they change continiously. so thought of keeping one more pc between the server and the router which will do the work of authenticating. but i am confuse as how to configure it to allow the packets coming from the internet after authenticating and to by pass the packets generated from internal LAN?

Ubuntu Networking :: "Wireless Is Disabled" For All Wifi With 10.04 On Asus A2500H?

Jun 16, 2010

having problems with wireless on my old Asus A2500H laptop, NetworkManager applet keeps the "enable wireless" greyed out and gives a "Wireless is disabled" for each wirelss network card. The wireless cards in this laptop are:

Code:
00:0c.0 Network controller: Broadcom Corporation BCM4303 802.11b Wireless LAN Controller (rev 02)
02:00.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)
It does look like the network interface come up fine as well:
Code:
wlan0 IEEE 802.11b ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=off

[Code]....

Of course the easy solution would be to just flick that hardware switch on, however there isn't any hardware button only a indicator light, which is off unfortunately.

Any clues to get wifi up? Also tried another pcmcia card but same problem, card is recognized but still "Wireless is disabled".
