I have various unknown Mac addresses on my network, I need to detect if they are normal/non harmful OR if I've been hacked! I've uploaded a picture of the addresses, the second to the last address is my router's.

View 1 Replies View RelatedI noticed two ip addresses reserved with DCHP on my home wireless. From IP addresses I can't seem to figure out who these belong to at home. All connected computers and devices are accounted for. Could these possibly be someone(s) hacking to my wireless to connect to internet? Or are these for modem setup, etc.?

View 17 Replies View RelatedSince i got sky broadband it's always been running super slow, the amount of times i have called them is ridiculous. So i have just been looking around on the sky address to see if i can fix it and in my Attached devices i have, the pc, an ipod touch and an unknown device. I'm wondering if this has anything to do with the slow speeds and maybe it's somehow 'stealing' my broadband. I've read a previous post of the same type but that wasnt for sky. i ran the ipconfig/all into CMD

View 2 Replies View RelatedAfter getting unusual IP conflicts on my laptop, I did a scan of my home network with a program called Zamzom and got the following results:On my Macbook I used a similar program and got more than 40 devices showing up: Neither program says which devices are active. The Mac results bring up BlackBerrys among other things. I upgraded my security from WEP to WPA2, but nothing changed. I use NOD32 and recently installed AdAware, which picked up a few things, but again, results are the same.

View 6 Replies View RelatedI found two unknown computers on my network (using Explorer). I have a wireless setup at home (private) with a desktop (wired), two laptops and a phone (wireless).The encryption is WPA2/TKP with a hard to guess password. The two unknown computers were connected this morning and a few minutes after I tried to access them and do some checks,they disappeared could they have been watching me? I didn't check the router page until then and of course, they weren't there.Also, yesterday I was at a coffee place, so could it be that this is nothing and those two computers are from people at the cafe? Is there anything I can do to make sure nobody can access my network, unless it's the computers I want. I haven't manually set up a home network yet. [code]

View 1 Replies View RelatedFrom Chrome when I try to download from a file sharing site I get "Unknown network error". And from firefox I get "source file could not be read". From internet explorer it just stops. The downloads don't even get halfway thew before failing. I didn't have this problem with this computer previously before I moved. I'm using the same access point and same internet connection. One thing I notice is that windows network center shows at times that I'm not connected to the internet but I'm still able to browse and use the internet. The disconnected icon only lasts for a few seconds in network center.So I think its some kind of settings or access point issue.

View 1 Replies View RelatedI recently purchased a Linksys EA4500 Dual-Band N900 Router with Gigabit and USB. Everything set up great with no problems and after a day or 2 I managed to get all home devices connected (2 laptops, 2 printers, an iphone, 1 tv, 1 blu-ray, an old desktop, and a tablet). Everything was connected right and working and I installed the Linksys app on my iPhone which let me see what devices were connected and all that. Well, last night, an unknown device showed up as a connected device. It's labeled as: android_(insert string of characters) and has a MAC address. I've tried and tried to identify what this device is and I can't. Everything else on our network is still showing up independently of that device. I'm worried that someone using our connection and possibly putting our device security at risk. What can I do to A) try to identify what the device is and B) if it is an intruder, block it's access.
View 9 Replies View RelatedIt may be a coincidence but my Broadcom Network Adapter 802.11g stopped working after trying to fix 'unknown device' in Device Manager (It was working perfectly before this).OS: Windows 7 Starter on 'BenQ Joybook Lite U105'.I tried the Windows Network trouble shooter and it didn't work (saying there may be a problem with the driver. I uninstalled the driver and re-installed it (including a possibly newer one) and it didn't work. Within 'Network Connections" the Broadcom wireless adapter is shown as 'disabled' I R-clicked to enable it, a window popped up saying it was enabled but it still showed as being disabled. My feeling is that something is preventing it from being enabled, logically, I would guess. Also went to 'Component Services' and ether started or restarted everything with the word network on it still no luck..My Google search on an other pc , now on day 3, couldn't find anything. (BTW the 'unknown device' which according to the icon, seems to be the joybook itself, is still not fixed and still listed as 'unknown device').

View 1 Replies View RelatedIn setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.
View 2 Replies View RelatedI'm planning to setup a network with more than 300 PCs. I know that using class C address is not enough to allocate number of IP addresses required. What I meant in the preceding sentence is that If I use this network address 192.168.1.0 (class C), it will allow only 256-2 = 254 IP addresses, What about other PCs in the network ?

View 1 Replies View RelatedI have a home network with a Netgear N600 as my main router. I have a wirelesss HP printer that accesses fine as does Iphones and Ipad. Then I have hard wires. Off of the main router I have 3 Netgear 5 port switches. 1 switch with a line to bedroom tv and a line to family room tv. 1 Switch at family room TV which goes to Blu Ray, Direct Tv, and Xbox360. 1 switch at bedroom for Blu Ray and Direct TV. Believe it or not, this all worked. I tried to hook up a ZmodoH264 security system (the ones with four cameras, and a separate hard drive and monitor for viewing). I used one of the 4 inputs on the main Netgear router for this, and it seemed to be recognized. But, I can't access the security system mobilly, AND all my network addresses seem to have been screwed as Directv isn't working (Whole Home) and the printer stopped being recognized. However, Blu Rays are still fine. Is there a way with ipconfig to list all of my hard wired nodes? I assume wireless dont show up in a list.

View 4 Replies View RelatedIn my wireless table of who is connected to the wireless network there are 3 different mac addresses displaying when there is only two computers in the house(its not an outsider, it only shows when the other PC turns on), 2 of them have the same computer name but are connected at different IP addresses(192.168.1.101,192.168.1.102). Side Note:[The 2 PCs in the house were bought at the same time and the mac addresses are similar, but the third is different] Now that i have installed ubuntu i can really see what's going on with my ports, i notice that the mac address, that is not similar to my PC and the 'other pc', is poking around at my ports whenever the 'other PC' is turned on.
