I think it's showing the speed that the wifi card on the computer is capable of transferring data at, rather than the actual download speed which would be determined by the ISP. If you type
You're right, mine shows as 144MB/sec.
48MBit/sec is 3x my speed, you're rocking!
Sorry, it's the other way around, I'm rocking!
My 'old ones' that were removed & stored somewhere are rated for 72MB/sec, and one of those are dual band with BT4.0. As soon as I seen the word 'Atheros' on an Intel based PC, knew it had to go. Wouldn't have mattered if it was rated at 144MB/sec, still would have went. If I wanted Atheros branded products, would have bought (or built) an AMD based PC. Dell had it masked well under the name 'Dell 1703', dual band wireless card with BT4.0. It was only when I seen Windows Update offered a Qualcomm update for the card that I caught on, and a replacement was ordered that very same day. The XPS 8700 'SE' models has the Intel 6235 cards, which I found brand new for $16, twice the speed & still have BT4.0 for when needed. Browser loads faster & less ping during speed tests.
Like Al1000 pointed out above, those speeds are only those attainable by the card, speaking of which, I may need another upgrade, a dual band Linksys router is supposed to be here in the morning. Need network cards for my main & 2nd best computers to match speeds as close as possible, both are dual band already, but only a fraction of what the router can deliver, though will have to wait until next month for any more upgrading, the router was needed because I'm having to reboot mine a lot as of late. Have never been able to take advantage of dual band speeds on my desktop PC, but have on my notebook in a relative's home, properly configured, two bands are better than one & makes for blazing fast wireless speeds. Plus, the router can download files w/out having an impact on PC performance, can attach a drive through the USB port & be notified when completed (part of the router's software). Actually, am going to use that port to share my non-wireless printer across my network & hopefully, it'll improve Linux printing, there is software for network printing which gets regular updates.
Really though, these wireless cards are inexpensive, brand new ones can be had for $32 or so, if the consumer is willing to accept the last-gen ones, which still is faster than I'll ever go.
I may give Mint KDE one last shot on my Optiplex 740, have been running MATE on it, but it's not used much. Would allow me to learn KDE at my pace and it take up no room on my main PC. Should run OK on an Athlon X2 4850e & 8GB DDR2 (PC2-6400) RAM, though I have to admit, that Core2Duo you have is a superior CPU over mine, and can more than make up for less RAM, provided you don't perform a lot of RAM intensive tasks. The Core2Duo is still a sought after CPU for enthusiasts who are running computers from that era, only the Core2Quad can outperform it on those platforms.
Will likely shop for a DDR2 motherboard that will accommodate one of these CPU's, surely there was a similar Optiplex desktop version that the MB can be swapped for, these MB's & CPU's can be found at great prices on eBay. The Core2Duo of that era will outperform any of the P4's, dual core Pentiums, and any other Intel CPU that will run on the platform, even if the GHz level of the Core2Duo is lower. This is further proof that raw GHz levels alone (e.g. P4 3.8GHz) doesn't make one CPU better than another, it's the bigger picture that counts. Though if I can find a MB, will be looking for a Core2Quad instead. These are now also very affordable & may be an upgrade path for you also.
At any rate, I believe this Optiplex 740 would make a good Mint KDE PC, and it has good enough of a GPU for the eye candy (1GB GDDR5 Dell OEM AMD Radeon 7570). I tried Cinnamon on it, and though it would run it fine due to the newer GPU, it's just not for me. Some weird desktop effects that makes me uneasy, I don't like this 'desktop behind a desktop' setup, which can be seen during certain times, such as when opening a browser & some full screen software. Didn't run KDE long enough to see if it's the same. but if it is, won't be holding onto it long either. I'm not into 'cube or 3-D desktops', preferring all to be in front of me, on one desktop.
One thing that I would like more control over in a KDE desktop is the bouncing effect that has to do with opening of apps. Maybe it can be fixed or eliminated with a Leafpad edit.
I will have to go to LM.com and look over all that install stuff.
Yes, there's a wealth of information on the site, including release notes, and it's where the OS is distributed from. Clem & the Mint crew are a very talented developmental team, surely any questions has been asked and has been answered on the site. I'm not speaking of the forum, that's in addition to the site information.
As to the 'over three minute' wait time, there's been times when that's happened to me on a MATE install, as well as Ubuntu 12.04 recently. Sometimes the reboot will hang for any number of reasons, members has reported this, however the computer usually will boot normally afterwards. There's a lot going on during the time of install.
