Intel Mac :: WLAN Internet Connection Very Unstable
Jun 8, 2012
I am using an IMac connected to the internet via wlan. While my windows laptop which is connected to the same wlan has no problem, the imac connection to the wlan is very unstable. Working online is thus a problem.
About a week ago I got a DrayTek Vigor 2910VG router. The thing's a dream in terms of features (VoIP, Dual WAN, USB port, etc.), but WLAN has been a complete headache. After a fresh restart of my iMac (see my sig for the computers on my home network, all of which are affected by this problem), I can usually connect to the WPA/WPA2-encrypted WLAN. Then, for reasons I can't determine, I will lose all access to the Internet and to other computers on the local network.
I've been having issues with my wireless. I use my home wireless network as my primary internet connection. I've noticed that I'll be using it without any problems, and then suddenly I notice pages arent loading (or if i'm playing WoW, huge lag spike.) The only way to get it going normal again is to turn the airport off and back on, and let it reconnect. Sometimes that fixes it for the rest of the day, other times I have to do that every 30 minutes. It just depends. I found [URL] but that doesn't seem to be the issue at hand, because my signal never drops, the connection just dies. Anyway of a fix? It's a pain in the ass to have to always turn my wifi on and off.
my question is if the internet is disconnected for a while and then connected again, will the system auto-start the schedule job again. Because the internet connection may not be very stable at the mid-night time.
What happens is that i attend a school, where we are 700 people using the same internet. Actually it's divided into 4 sections, so there are probably 250 in my group. This network is protected by a WPA2 password, and has additional login forms, which gives the school the ability to check all in- and outgoing transfer. However, I have lately been getting some problems connecting. What happens is that I connect, and it works for about 2 minutes. Then, it just won't load any sites and just keeps trying to load until it finally admits that it can't retrieve the server. It's my third year. and I have never experienced this before, so I thought: Well, gotta be the school's internet, but i haven't heard of any other ones having this problem. This makes me worried that my macbook's airport extreme card is broken.
I was wondering if anyone had experienced a similar problem, or maybe could give a hint towards a solution? I am running a 13 inch macbook unibody (the silver one), with the newest system and all upgrades installed. Problem is: The airport extreme card is located in the display. I don't get why, but it makes me not want to change it myself, should it be destroyed.
I moved my room around yesterday, and originally my iMac was in the far corner of my small bedroom. After the rearrange, now its on the opposite side of the room, and since then the iMacs internet connection has been unstable. It'll drop, randomly slow down to a crawl etc. My MacBook is fine, and so is my PS3, its just my iMac thats causing havok, all because I moved it from one side of the room to the other. I can't be because I've simply moved the iMac from one side of the room to the other can it? My MacBook can pick up a strong signal from the bottom of the garden, so the iMac really has no excuse.
My iMac keeps dropping internet connection. This has only been a problem since installing Lion, it often tells me there is no connection when my iPhone and MacAir work perfectly so i know its not the broadband itself.† I also get the message that my network configuration has changed.
I have an iMac (without an Airport Base).† It is connected to a Sky router through an Ethernet cable but still with wireless capabilities. The internet connection keeps dropping out at regular intervals throughout the day to the point that my partner may just throw it out the window! The router lights still show it is connected as does the wifi signal at the top of the screen. Our iPhones still work even when the Mac drops off.
Recently just switched from 16mbps to 100mbps internet connection. Internet is connected tru Wifi and max speed i get is nothing more than 15mpbs and if connected through ethernet ill get speed more than 80mpbs. How to acheive 80-100mpbs tru Wifi? Called my service provider and reason given was that my network card doesnt support or its an old network card but my iMac is new
Since last week my iMac (Early 2009, OS 10.7.3) has been dropping its connection to the Internet. I'm using a router connected to an Airport Extreme and connect to it via WiFi. I tried connecting via Ethernet cable from modem to iMac but it would drop the connection entirely, which is why I had been connecting via WiFi. I have no problem with my other devices (iPad, iPhone and MacBook, this one with 10.7.2 installed), they connect immediately to the Internet and all, even the iMac, are able to connect to each other.¬†
I already tried restaring the Airport Extreme, zapped the PRAM, reset the SMC, repaired permissions, disconnected the router and Airport from the power source and it still won't connect. Last time this happened, my iMac went to sleep and dropped the Internet connection after waking. I put it back to sleep and woke it using the power button as someone had suggested in another post, that helped and the connection was reestablished. This morning the iMac it was working fine, did not go to sleep at any time and suddenly dropped the connection, which I haven't been able to restore since.¬†

Every hour (or even more often), I get the message "Safari cannot connect to the Internet", followed by a prompt to run diagnostics. I run the diagnostics, re-select my network (provided via BT Hub) and pronto - the issue is fixed, by why does the connection drop so often. Surely this can't be right - I can't be doing that every time I want to go online. ¬†
Interestingly, my iPad (which uses the same network and Safari) never drops the connection, so it is something to do with the iMac.
I'm newbie an just using apple the first time in my life. I bought imac i5 2.7 ghz..Can someone help me about my problem? I already check with my inet provider that my connection got no problem at all. But i felt that it is slow and the worse case again when back to my old windows notebook, i got no problem with the connection. The imac performance itself got no problem.
My internet connection has always been very fast and I have never had any problems with its speed or loading of web pages. Over the last two day I have experienced extremely slow connection speeds and webpages have been taking forever to load. Is there a setting I can check or cache to empty to help speed up my connection? Or is there a disk cleanup to help get rid of whatever may be causing this problem?

I have a 27" iMac running OSX Lion 10.7.3.¬†Some time in the last 2-3 weeks, it has started to getting into a state where the kernel_task is using 100% of one CPU constantly.¬†When this happens, it also kills my Internet connection and I cannot use the browser, email, Skype, Twitter, etc.¬†I have tried putting it to sleep, closing all programs that are open checked the process list with ps to see if I could find anything weird, but it still keeps happening.¬†
I have to restart the computer whenever this happens.¬†It might happen again in a couple of minutes or not for several hours, but happen it does.¬†I thought it might be Chrome or Mail for a while, but it happened today when those were not running.¬†
I am having trouble with the ping speed on my internet connection; it is registering at 174 ms, which is too high. My iMac is a 2009 24inch model running Lion. Is this due to my wifi or is it the ip server?
I have two identical iMacs hooked up to a router. Both had no internet connection problems until now. One iMac works fine, the other just stopped. I swapped LAN cables and router ports but the iMac that quit connecting still won't connect.
I do not have a problem with the Internet while I am using the system. However, when I wake the iMac up in the morning, there is no Internet connection.I have to use System Preferences/Network/ and select the network.iMac / Intel / Mac OS X version 10.7.3

Iimac uses airport extreme. For no known reason stopped connection to Internet. Reset. Still no connection with saying cannot connect because it timed out. When I connect extreme directly to the iMac I can get Internet. If I disconnect Internet does not work
Just got a new iMac and when I use safari, my connection is VERY slow.¬† I have my old imac and other NB's running on the same home network and they work very fast and work fine.¬† my new imac seems to show the address it's going to but sits there for literally min's before it connects or if it connects.
