Hi James, |
80 |
|
81 |
:) |
82 |
|
83 |
The solution was as simple as follows: |
84 |
|
85 |
I did this: |
86 |
|
87 |
./create_ap wlan0 eth1 <name> <pass> |
88 |
|
89 |
and I was happy to have my first access point created... |
90 |
that one which seems to use morse code to transfer data. |
91 |
That was yesterday evenining. |
92 |
The I heard of different protocols from which one was |
93 |
old and slow and others speedy and "newer" |
94 |
|
95 |
Then I did this (a few miniutes ago): |
96 |
./create_ap --ieee80211n wlan0 eth1 <name> <pass> |
97 |
|
98 |
And TADA! the internet transfer rate measured with conky |
99 |
(as mentioned before) jumps from 80Kb/sec up to the most |
100 |
my DSL can delver (which is not that much, since I have |
101 |
choosen a cheap low end of transfer rates possible from |
102 |
my DSL provider. NOW the linux installation on my Android |
103 |
tablet show real progress (and fails for other reasons, |
104 |
I currently dont have figured out). |
105 |
|
106 |
I am happy with the result - except for the non working |
107 |
Linux installation, which is another problem...unfortunately |
108 |
I dont speak a single word Russian and the forum of the |
109 |
Android Installation tool is Russian spoken... |
110 |
|
111 |
We will see, James. |
112 |
|
113 |
Thank you very much for your detailed help!!! 8) |
