Cisco Wireless :: Copying A New IOS Image Into AP801
Oct 22, 2012
I struggle with how to install an IOS into an AP. And I am still not very clear on how this is to be accomplished. I have an 881W and have downloaded what I believe to be the latest IOS for this AP (ap801-k9w7-tar.152-2.JA). Problem is that I have not really found a good or at least clear set of instructions in how to load this IOS into my AP, so I have not done that yet.Does the IOS that is currently installed into the AP remain after an update or does the new IOS overwrite the current IOS. And how does one recover from a, heaven forbid, faulty installation. What is the fallback from that. How I can update my AP. Because, right now, I am most certainly hesitant to even attempt an upgrade.

I have an integrated 881W with a built in 801 access point. I'm interested in increasing the range of my AP. I'm interested in considering any configuration changes while still maintaining support for N. I've included a copy of my running config.As well, I've heard of high gain antennas. I'm using the default antennas that came with the 881W. If there are better antennas that I can buy to increase my range, I'm interested in considering that as well.

We are having issue with all our Cicso wireless devices (AIR-AP1142N-N-K9) when connected to Windows 8 Pro users. When copying large files, the connection changes to limited access. The initial connection to the access points is also slow for both windows 7 and windows 8 pcs.

I'm looking at adding a Cisco 3750-X switch running c3750e-universalk9-mz.122-55.SE1 (IP base license) into a stack of 3750-G switches running c3750-ipbasek9-mz.122-55.SE1.bin Given that the version and feature sets are the same I don't forsee any compatibility issues. Would there be any reason why a universal image wouldn't stack correctly with other switches running the single .bin file?

I have a laptop (let me call it A) with Intel Centrino 1030-N wireless (iwlwifi module), running Arch Linux, and another laptop (I will call it B) with Atheros AR928X wireless (ath9k module), running Ubuntu 11.10. They connect to a wireless network provided by a D-Link DI-524 router (802.11g), which in turn connects to a DSL modem (10Mbps/1Mbps link)
Copying files between those machines, either through scp or mounting a share via NFS or Samba, is very slow (at most 200 KB/s) and sometimes fails (times out), even when both machines are inches away from the router. However, downloading files on either machine works correctly at the expected speeds (~1.2 MB/s).
I ran iperf, as recommended in a comment, and it gave me this: [code] The bandwidth is very low, as can be seen from those results.

I have two mac laptops and am trying to copy a directory with a number of PDFs in it. The files aren't particularly large, but there are many of them. At some point in the process the router stops and must be turned off and on before it will respond again either wirelessly or wired. I have tried the same experiment with both devices wired and the router works fine. I have tried changing the MTU, channel, beacon setting, etc. as other forum posts have tried. I tried reflashing the firmware, resetting to factory defaults and reconfiguring. So far no success. Cisco support wants me to return the router. Frankly I'm at the point of considering the former Linksys/Cisco products complete rubbish. I am going to have to buy a new router even if I return this one since I can't be without a router for any length of time.

I transfered both shares to the NAS last weekend, and plan on configuring the shares to be hosted on the NAS this weekend. In order to do this, I need to copy all of the changed files to the NAS in the most efficient way possible. I was thinking of using either xcopy or robocopy. What do you think? Is there a command in either one that would allow me to copy only changed data? I don't want to wait another 18 hours worth of copying to move all the information over AGAIN

My parents bought a new computer today. My mom called me up today and asked me if I could transfer some stuff from the old computer to the new computer. I do not have a flash drive or an external hard drive, or jump drive.etc. So I was hoping I could just connect the two computers with an ethernet cable, and create a network.
Is this possible, or do you need additional equipment. I do not have a router, so if I create a network it has to be done with wires. So is it possible to create a network with nothing but an ethernet cable? Or is there another way I can get my moms i tunes transferred over?

I can't seem to access the Net when transferring large files between my desktop (WinXP SP3, 100Mbps net card) and my laptop (Win7, 54Mbps WiFi). I have an EDIMAX BR-6228nC 150 Mbps broadband router to which my desktop is wired and the laptop connects through WiFi. The speeds never go above 2.5MBps, so there should be plenty of bandwidth left for Internet use. My router config confirms that there's no Internet connection while transferring the files

I have a Cisco ASA 5510. I am trying to copy large files between DMZ and INSIDE network and it is copying at awfully a slow speed. I thought it might have been related to duplex mismatch but it doesn't seem to be. DMZ interface is set at 100 full duplex. I programmed the port on the managed switch where the DMZ uplink is connected to be 100 full duplex. I even hard set the NIC on server to be 100 full. Nothing worked. So, I come to a conclusion it isn't the duplex mismatch but there gotta be something else on Cisco ASA. I was googling for this issue and came across it could be a QoS policy. Now, checking my ASA I see a any to any global service_policy where it is defined to inspect certain protocols where 'netbios' is one of them (among others such as 'ftp', 'tftp', etc. Could the slow copying be related to the above policy? Could there be a bandwidth limitation between DMZ and INSIDE interface? How do I check?

i have to configure 80 Cisco 876 routers, so i planned to copy config via tftp from one configured router to PC, edit it in text editor (change ip addresses, dhcp pools, vpn keys...) and then copy it via tftp to another router, etc... Configuration looks fine and it works when i paste it in cli, but when i copy it via tftp i'm getting strange problems like dhcp not working or snmp not accessible. Am I missing something.
Here's config from router with dhcp problem:
ROUTER#sh run
version 15.1
no service pad
service tcp-keepalives-in
service tcp-keepalives-out
service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone
service password-encryption
service sequence-numbers(code)

When I try and copy files from my Windows 7 Home PC to my Windows Server 2003 share, it copies so much then hangs the Server sharing. It then appears that the share has disappeared. If I copy from the Server 2003 to 7, it copies fine, and copying from XP to 2003 also works fine. I had a chat with a colleague who told me that he has the same problem copying from Vista to XP.

I am working on a small business network. 8-10 computers, usually only 3-4 being used at any one time. I'm trying to improve network file transfer speeds between the local machines and a network READYNAS NV+. There are both 32 and 64 bit OS's in play. Between the READYNAS and the local machines are two non-managed switches (jumbo frames capable) and a patch panel. The cable from the READYNAS goes into the first switch, then out of that into the patch panel then into the second switch, and then out to several local machines.
Though i would love to improve performance to all the local machines, I am primarily concerned with one in particular. It has Windows 7 64 bit and an onboard Broadcom Netlink Gigabit network adapter. This device does NOT have a Jumbo frames option in the advanced settings. Here's the issue: When copying files from the READYNAS the upload speed is only 16mbps (jumbo frames enabled on the READYNAS) if I turn jumbo frames off on the READYNAS the upload speed drops to 9mbps. Just FYI, this is a photography studio and the files are always LARGE.
I have several questions that hopefully will lead to an illuminating discussion. 1) Is it possible that the universal patch is in any way a problem? Sorry if that is totally stupid, but I've never encountered one before. I understand routers and switches, but this patch thing is new to my experience. 2) Is having two switches a bottleneck? 3) Is it possible that the onboard Broadcom network adapter is junk? Why doesn't it have jumbo frames options? 4) Could I get better performance from an add on network card in a PCI-E slot and a couple of managed switches?I realize I'm all over the map here. Bottom line, I've got a small network situation here. Very simple, uncomplicated layout. All I want is better read/write performance to a single READYNAS NV+ to a handful of local machines. If I need to settle, I can live with better performance to the one single machine. 16mbps just seems tragically slow.

My work has a main office and a backup office which is off site. What I am trying to do is copy a folder from one computer at the backup site to another computer at the backup site, all while sitting at my computer in the main office. Let's say the two computers at the backup site are called comp1 and comp2.Whether I use Windows Explorer, or .net VB script, or XCOPY from the command prompt, if I try to copy \comp1c_drivefolder to \comp2c_drivefolder from my computer then it takes an extremely long time - around 5 hours for 2Gb of data.
However, if I Remote Desktop into comp1, and from that machine copy C:folder to \comp2c_drivefolder then it only takes 5 minutesI can only assume that when I try to copy the folder from my computer remotely that it is transferring the data from comp1 -> my computer -> comp2, and with the computers being at different sites it's very slow. What I need to know is if I can do this remote copy using VB without the data going via my computer, i.e. straight from \comp1 to \comp2.
I thought this was the way Windows handled copying between networks anyway, i.e. straight from one to the other, my only explanation for the terrible speed is that it is going via my computer. I'm writing a basic folder-backup program in VB and would REALLY like to cut that 5 hour transfer time down to the 5 minutes I know the network can do

I have a HTPC running XP and a Media Player connected on the same wired network. I also have a Win7 laptop connected to the same network over Wifi.
From the laptop I want to send files between the HTPC and Media player on the wired network however if I drag and drop or use the "send to" option they are sent via the wirelss laptop which is very slow.
Am I missing a trick how can I send files directly between the 2 devices?

I was using my laptop - working in MS Word and hadn't even opend a internet browser and suddently a command prompt appears and all i managed to see before closing it from the task manager (which had it running through internet explorer i think) was that it was copying files.Its a work laptop so i would like to know if it was remote access from IT which seems doubtful on a Sunday or if i need to be concerned about security. Is there a relatively easy (considering i have zero programming experience) way for me to check if anyone logged on with remote access and who and what files were copied?

When I use ASDM or the CLI to copy (ftp) files from my management station to flash on my ASA5520. I get to 99% and then the gui or cli window hangs.
The ASA itself completely freezes i.e. no traffic in or out until I kill the transfer window and then it may reboot
[and yes, there is more than enough free space on the flash file system for the files]
ASA5520 V8.2(3) / ASDM V6.4(5)

I was upgrading IOS on 4507 R with dual supervisor.I download the IOS on Active supervisior and did reboot.After reboot i login to switch then i got switch standby prompt.I found that after reboot active supervisior became standby supervisior.
Now new IOS is on standby supervisior.Need to confirm below..So this means that IOS does not syn within the supervisiors as compared to config right ?
-Which command i can use that will copy IOS from standby supe to Active supe??
-Which command i can use that will show both active and standby supe with new IOS?
-Is there any command that i can use to switchover from active to standby supe??

I'm looking for some software for copying large amounts of data from a Mac OS X machine to a Windows 7 machine over a Cat5e cable with IPv4 connectivity?
Another way I could ask this question is what IPv4 protocol will have the lowest overhead so that I may copy large amounts of data the fastest?
Also, would that mean it's a low-level protocol, like transport layer?
