View 2 RepliesHow can I block my son's computer from internet access through our wireless router without having his computer in hand? I have accessed the router on line but don't know what to change there.

We have two network (one have internet access and other doesnt have) within a same office and some pcs are connected to both the network using two NIC. So i am planning to implement a router in between those network and as it implement default routing so we can share all the resources. make both the network secure from virus as one of the network should be worm free. What i personally think that implementing a router will reduce worm replication.

So here's the deal, my friend has horrible down speed, usually less than 1MB/s according to Speedtest.net, sometimes it hits 2MB/s. However, his brother's in the house have at least 17MB/s, which I can assume is their actual speed that my friend should have... however, he specifically does not.He had a very old wireless card that was installed on his motherboard (desktop PC) that I assumed was the issue upon him first telling me, and from the issues I was personally able to see. For example, he'd constantly disconnect... his internet would just die for him specifically, and then come back. His brother's never lost internet when he did.
After that, I figured his very old wireless card that was installed was just kicking the bucket, so I instructed him to replace it. He went out and bought a new wireless USB adapter, and then uninstalled the network card.Even after all of this, his internet is still poor in terms of down speed. HOWEVER, rather than his internet dying for a few minutes at a time every so often, his internet "stays connected" if that makes sense? For example, we'll be on Skype in a conference call, and his internet will be loading pages very slowly, and Skype will constantly show that it's going from "green - online" to "gray circle - connecting". During this, he's still in Skype, but it's very poor quality from him speaking, and laggy as well.

View 1 Replies View RelatedI purchased 3 AE2500s to connect 3 machines in my house.2 of the machines it works great. However on the 3rd machine, when I start browsing around (2.4Ghz or 5Ghz), things start going wonky and then the device basically loses connection, and the LED indicator starts flashing consistently indefinitely (with no connection).Removing and reconnecting the USB device will allow me to reconnect to my network and do stuff until it happens again. Speedtests on speedtest.net ALWAYS fail on upload test, I lose connection then.Streaming a movie across the network immediately causes this (exclamation mark on network icon) Regular browsing causes it also Checking event logs, I get the following error wlan extensibility module has stopped bcmihvsrv.dll The router is an E4200 I have tested all 3 AE2500s on this single machine, and they all do the same thing.Out of the 3 machines ONLY the one that doesn't work is Windows 7 32bit, the other 2 that do work are Windows 7 64bit Considering the event log is complaining about bcmihvsrv.dll, I know the 64bit version uses bcmihvsrv64.dll, could it be a bug in the 32bit drivers?I have attempted at trying different slots, uninstalling the drivers, removing and disabling any other network components in this single machine, lowering the power output in the advanced options, tried 2.4ghz and 5ghz, tried Wireless G only and then Wireless N only...

My roommate has refused to pay her share of the internet and, being a college student, I don't have enough money where I feel generous enough to let her have free internet after stiffing me. Basically, I have 2 routers at the moment (hoping to fix this soon): my Qwest modem works as a router but I also have a Linksys router connected to it. The only phone jack is in her room so I have no way of stopping her from plugging her computer straight into the modem and/or router. I've configured the wireless so that she would be unable to access the, wirelessly but I'd like to know how to prevent her accessing the internet when she plugs her computer directly into either component.

View 3 Replies View Relatedhow to check compliance for only one access list in cisco works.
Example:
I want to run a compliance template that only check access-list 13 to make sure it has the following and nothing else:
access-list 13 permit 1.1.1.1
access-list 13 permit 10.1.0.0 0.0.0.127
If something else is listed, then I'll deploy the template and it will remove any other entry besided the two above.
I have tried a Global config compliance on + access-list 13 permit 1.1.1.1 and it comes back and says it's not compliant and wants to remove everything else, which is every other access list. I have tried submodes thinking that it could check under ip access-list standard 13, but that didn't work either.
When I turned my computer on this morning, it had no internet access.
I haven't changed any settings - I think there was a Windows Update though.
Windows 8, Intel 82579V.
The DNS settings are correct, that is, unchanged and what we have always used.
I can access the network fine, browse shares, see the other machines etc. but the network icon in system tray says "No Internet access.".
I can ping the gateway.
All other computers on the network have Internet access.
The network cable works and provides internet access when plugged into a different computer.
I have tried disabling IPv6. I have tried disabling/enabling the network connection. I have restarted Windows multiple times. I have tried disabling Windows Firewall.
I am at a complete loss as to what to try next.

View 1 Replies View RelatedI am setting up a network for a friend with children. He has a BT homehub and wants to block their access between certain hours. However by using access control on BT it tells you that you have been blocked which is no good as he cannot feign ignorance and pretend he doesn't know what to do (as his kids will pester him to fix it). He therefore wants to block their access more discreetly (as if the internet was generally timing out or messing up instead of actually displaying they have access control).Is there a way to block an individual's access on the router without blocking everybody either on a timer or manually done each time (thus if there isn't a way of automating it he can at least do this manually each time).
