You would think that's easily found via Google but that is not the case Our firewall seems to be blocking some file transfers from wireless clients logged into the domain to our Server 03 file server so I need to make an exception but I don't know what port is actually used for that.

Netgear Wireless Bridge connects to my long term hotel's wifi, and feeds via ethernet into the Internet port of my WNDR4000.WNDR4000 has my Desktop and WHS connected via gigabit, while the HTPC is 450mbps wireless N with an Intel 6300n, and my Macbook air is connected via 5ghz wireless n as well.I'm having a very bizarre issue where all large file transfers - even over gigabit - are corrupted, while direct downloads are not. I've been pulling my hair out trying to figure out why I CANNOT make a working windows install disc from a tech net iso, and eventually starting checking sha1 hashes. This is how I discovered that direct downloads to machine's hash correctly, but if I transfer it to another machine the sha1 is completely different.
For example, if I download the iso on my macbook air and transfer it to my WHS, the hash is correct on the MAcbook but on the WHS it fails. If I download it to my desktop and transfer it to the HTPC or WHS, same thing happens. There errors are bad enough that Windows setup errors out with a corrupt file error if I make the disc from a networked machine. I have to use the local file to get it to work.
I have a couple of pc's between which I transfer video files using Wifi, one is a laptop running XP and the other is a media centre which *was* running Windows 7. The laptop is connected to an N router using an ethernet cable to increase speed and because they are located next to each other, and the media center which is on another floor of the house uses a Wifi connection to the router.
The file transfers between the pc's used to run at about 70Mbits/sec which I was happy with. However due to problems with the media centre, I recently downgraded that pc to XP since I get much smoother HD video playback from XP MCE. But... since these changes the transfer speed has now halved to about 35 Mbits! Remember all the pc and network hardware is the same, the only change is to the operating system on the media centre pc.
At first I though maybe the different XP drivers for the network card on the media centre might be rubbish, so I changed the network card altogether, but the speed has remained the same. I have also stripped the networking configurations down to the minimum to reduce overheads, so have removed QOS and unnecessary file and print sharing etc. But none of this has worked. Am I missing something in the XP network configuration that might correct this problem, or is it simply the case that Windows 7 Wifi is just that much improved and faster than XP?
I'm presently experiencing an issue with my Latitude E5410 notebook where the NIC disconnects during large file transfers. For instance, if I were to copy a large file (50+ MB) from a network drive (or vice versa, copy a 50+ MB file from my notebook to the network drive), the network icon in my taskbar suddenly changes to "No Network Access", the transfer fails, and I can't access any network resources until restarting my workstation.
At first I thought it was the network backbone in our office (SonicWALL Gateway + Dell PowerConnect switches), but this error also occurs at my house with my own networking equipment (D-Link) and NAS. The Latitude E5410 notebook is running Window 7 Professional SP1 and has a built-in "Broadcom NetXtreme 57xx Gigabit Controller", and a "Dell DW1501 Wireless-N WLAN Half-Mini Card". However, this issue seems to only occur with the Broadcom adapter when I'm physically connected to our network; when the Broadcom adapter disconnects, I can connect to our local wifi network and access network resources.
I recently got a Static IP from my service provider, I'm working from home & configured a FTP server in my PC.
I have to transfer huge files say around 40 GB of data as I'm a Multimedia professional. I was using my web server, before for file transfers but there are lot of limitations to huge transfers.
My client, who is downloading using my Local Server says, it takes 3 mins to download a 9 Mb file, which took 17 sec before, when it was done with the webserver.
Does this have anything to do with my Internet connection speed as my speed is 1 - 2 Mbps. If not is there a possibility to increase my transfer speed ?
I have a WRT54G v6 router and I am trying to get higher speeds from a wireless network, I have set up a dish and a cantenna and is going really well about 18-22dbi gain which is very noticeable but I have a question, does an ?Ethernet cable speeds up the transfers Like the Upload and download speeds will be faster? like a high speed cat7 or cat6 cable that can transfer data at much higher frequencies? I have cat 5 and get around 13Mbps, will cat 6 get me 16 or 17? or the router can't handle it?.Also another question is how can I make the gain on the dish higher?
View 2 Replies View RelatedI am a new network admin at my company, and I am investigating a problem that is on a network designed by someone no longer here. So, I can't ask why things were set up the way they were. Anyway, here's the issue:
We have 50Mbps WAN connections between locations. The WAN devices are 3750s, but the port plugged into the providers network is a layer 3 port. Config is below for one of the ports: [code]
So, these are Gig ports, but our service provider limits to 50Mbps. When we do a data transfer, we can't exceed about 20Mbps total on the circuit. The data transfers at maximum 15-16Mbps.
I'm not familiar with QoS. I've tried to read more about SRR, but don't understand it well enough to know. Are the QoS settings creating this restriction? Our provider swears that the bandwidth is allocated and its not being choked on their end. I have not taken off the QoS config to test it that way because I'm not 100% sure if its needed and serving some purpose. I don't want to break something in order to fix this.
Is the QoS causing this? Do I need to put a bandwidth statement on the port? Should we be using routers and LLQ?

Whether it be downloading or just trying to watch a video on youtube. For some reason everytime I try to download something it appears to start fast but then it basically just stops. I'm running windows Vista and I've tried going into the router security settings and unchecking Block Anonymous Internet Requests.
Recently purchased a Linksys E4200.Computers on network:Two hard-wired gigabit desktops: one Windows XP, one Windows 7One hard-wired 100mbps desktop running Windows 7One laptop with an Intel 4965AGN running Windows 7.File transfer rates between any of the desktops and the laptop is very slow: ~2 megabytes/s
File transfer rates between the gigabit desktops is good (~50 megabytes/s, hdd bottleneck), transfers between the 100mbps desktop and one of the gigabit machines gives ~10 megabytes/s.Currently running on the 5Ghz band, connected with N at 300 megabits, good signal strength. Disabled mixed mode on this band, enabled N-only.Use a scanner tool, I can tell that there are no other networks on 5Ghz band.Also, tried 2.4 Ghz band and got similiar low speeds.These transfer rates are much below what other people report for real-world throughput. Any ideas? I know there is an Advanced Wireless config page, is there a setting there that might work if adjusted?
This is a new RV180 install. FTP data transfers fail in binary mode. By fail I mean the first packet sent, isn't accepted (acknowledged?) by the FTP server (Network Solutions, Passive Mode), . If I pull the router and replace it with an old D link router or 5th gen Apple Airport Extreme, everything else the same, it works OK. I lack the tools and knowledge to proceed beyond this point.

I have upgraded to the latest firmware which solved lots of problems regarding unstable wifi connection as well as BitTorrent / P2P transfers.But I also observed that when my BT is on (Transmission for Mac) at around 50KB/s upload and download, my network latency hikes up from some 30ms to 500ms which affects a lot on web browsing or other apps requiring Internet.My BitTorrent app is showing I am merely making some 20 peers connection so I am not convinced that is an ISP problem but it's more about the router.
I am working on a Drupal site which is on a virtual server (the way it's been explained to me). I've been told I need to work with it through webdev. So I can copy a file off the server and onto my local machine. I make my edits and then try to upload it to the server. I get locked out with the message: Error 0x80070021: The process cannot access the file because another process has locked a portion of the file. I have tried shutting down my code editor, opening and closing the connection, tried different methods of reaching the server (Cyberduck and through Window's map network feature) to no avail. What can I do?

The configuration is as basic as I can make it, no VLANs, QoS or bonding. Both have been updated to current firmware as part of the troubleshooting process.
When I transfer data within one of my switches I see 50/60Mb/s. When I pass the same traffic between both switches I see 0.6 Mbs/ or less.
I have tried to eliminate every possible factor including switching out the cables. No success.

Is there any way of forwarding an external port to a different internal port on the TD-8970 ?I saw a question posed on an Australian forum implying that it might be provided in a later firmware release.Our TD- 8970 has replaced a previous NetGear WAG 320N which had this facility, and is useful to provide access to multiple machines without having to modify each individually to use a different port.
We just installed a hosted VOIP system using Cisco 7900 series IP phones. We are having a strange issue with a few computers where they pull DHCP information from our VOIP provider's DHCP server on the Internet and not our LAN DHCP server.
The switchports areconfigured as: switchport mode access
My rationale behind this is that the phones would use CDP to get their VLAN info from the providers Cisco router and the PCs would just ride on the default VLAN. But this is not the case. Computers randomly keep getting DHCP info from the provider's router. Do I have to use voice vlan x and make the switchports trunks?
So here is my network.
ASA5505--->Cisco1841--->Cat2960

Cisco 1841 c1841-adventerprisek9-mz.151-4.M2.bin
Cat 2960 c2960-lanbasek9-mz.122-55.SE1.bin
and here is my dilemma.
I can SSH from the internet to my ASA on default port 22, directly to my public IP. I can SSH from the internet to my Cisco 1841 on port 2001. I can not however, SSH to my Cat 2960. From what i can tell, on the Cat2960 i can't change the default port 22 for SSH to different port, just like i did on the Cisco 1841. I looked to see if I can change the default port for SSH on he ASA, it does not look like this is an option.
The bottom line is that i want to be able to SSH to all three devices from the internet. I only have one public IP. As of now, what i can do is only SSH to the ASA on default port 22 directly to the public IP and Cisco 1841 on port 2001. It appears that changing the default SSH port on Cat 2960 is not an option. It also appears that I can't change the default SSH port on the ASA, if i could, i would and then i should be able to SSH to the Cat 2960 on port 22. No matter what i did on the ASA, it always listens on port 22 for SSH connections.

Seems to work just fine when I plugged in an test. But I am not routing across that link yet as I still need to setup the far end.

I have a 3750g connected to a "core" switch stack of 7 other 3750g's via 2 GigE ports in a trunk. This is currently in a switchport mode access port- channel so only the default vlan data is sent over. Now we have a need due to physical location of these switches, to allow vlan20 (DMZ) from this 3750g to the switch stack. I will configure a few ports on the switch stack for vlan20 and they need to be able to talk to the stand alone 3750g.To do this I will change the port channel on both endpoints to
-switchport trunk ecapsulation dot1q
-switchport mode dynamic desirable
also making the appropriate change on the interfaces belonging to this trunk.My question is, now that its a trunk port that carries multiple VLANs, how much is the bandwidth reduced on that 2gbps link?I have a very active VLAN (10) on the stand alone switch, but on the core I'm not going to be assigning VLAN 10 to any ports. So does traffic from VLAN10 even come across the trunk (wasting bandwidth) if no ports on the core side are assigned to it? I really just need vlan 1 and 20 (for now).
is it possible to shutdown a specific port on my 3750x and monitor this port at the same time .for example , im dealing with a mac authenticated network using port security , i want to shut down all the ports that are not used at the moment , however , if some one gets connected to the one of the shutdown ports i want to know the mac address of the user or atleast to know that i have someone who is just plugged in to the one of the shutdowned ports .
