M4800 Owner's Thread

No, Im using autocad for general arrangement drawings in ships, 500-6000m2 packed with 3D block furniture, other times I do alot of hash to calculate square meters of everything, in 3-5 different layers on top of each others and that seems to really stress my system! I also switch alot between different drawings so I need to run a couple of 30-100mb drawings open at the same time + some 50mb or more PDF`s - Large excel sheets and a couple of browser pages...

 

Unfortunately its a "no go" for this as an alternative drive... I was part lucky I got normal 2.5 inch drive by mistake due to wrong image been used by company that sells them so they refunded me. I then got a bit impatient and tested normal MSata (which is what I should have done in the first place and not waste time on pipe dreams) and its said... Nothing.... wasnt recognized, soits safe to say slot is useless. back to RAID 0 as best bet. as for wear and tear of laptop I have found a very nifty solution will upload pictures as soon as I can, youll be surprised how easy you can protect it with 3$ invest.

 

If you're pegging the CPU, you probably could benefit from the more powerful CPU.

It's a shame that the finish wears so quickly - it might seem shallow but I do like the industrial look of the M4800 and to see the finish/paint wear to easily is a little sad.

 

I have no idea if this will help you but for years I had problems with occasional random disconnects. I had maximum DHCP users in the router control panel set to the exact number of devices used (3-5). Then I read that it needs to be higher, say 10. As soon as I changed that setting, no more disconnects. You might try increasing that and see if it helps but your issue sounds different. Also check your wireless channel, interference from other wireless devices, security software and windows network settings (sounds likely). In the Proset control panel try switching between let Proset manage and use Windows to manage wifi. Your ISP might also offer some help with this issue.

After years of using notebooks with no backlit keyboard I found that when I need it I really need it so the superior backlit keyboard on the M4800 was a selling point for me. I'll never get another notebook without a backlit keyboard.

 

I appreciate all your links, but I think I solved my problem. Specifically it was that the Intel 7260 wireless card really required an AC router to perform. It had a difficult time with the D-Link N router I was using; and, too, the drivers Intel initially came out with were half-baked. That has since improved. I bought the Netgear R7000 AC router, and ever since it connected to that baby, there has been not one disconnect. Going on 2 weeks now. Fingers and toes still crossed, but I think that was it for me.

 

I'm trying to access a university network from a distance with an M4800 that has a Intel® Centrino® Ultimate-N 6300 as a wireless network adapter. The signal is ok, but not great. I tried a few WIFI dongles that had external antennas but none of them seem to have the range of the N6300 and the signal is worse.





There are three small antenna connections on the card. How could I connect an external antenna to the three of them to further boost the range? I read on another site that something like this could be connected to the card. but not sure whether I'd need 3 antennas or whether there's some sort of MIMO antenna with a cable I can attach them to. Something like the following was suggested to attach to the card, but unsure what happens with the antenna itself.

Anyone done anything like this successfully?

 

For what use? In your dorm room? They have crappy coverage?

If so I would get an access point to pick up the signal, then run a cable to my laptop.

I wouldn't know of a way to connect external antennas to an internal wifi card. Usually the 6300 is pretty good.

 

Once I was forced to innovate and made few quick designs to boost local wifi signals.

hope these pictures will give you a clue how to boost WiFi signals.

Physics remain the same generally.

Best thing this type of DIY booster does is that it kills interference from the back and allows to receive better from the front, so you can get more reliable hook to AP. best to use solid metal, small satellite dishes (mesh) don't give much more than 70cm metal bowl sold for a probably 2$, as at some point it becomes useless due to sensitivity and power of dongles/wifi cards themselves,

I have managed to boost most signals by 20% upto 30% which is enough to get a hook. (it was long ago) best dongles were non MIMO enabled Buffalo and netgears were on par.:thumbsup:
